Sarah has received £ 294
Solution:
Given that £980 is divided between Caroline, Sarah & Gavyn
Let "c" be the amount received by caroline
Let "s" be the amount received by sarah
Let "g" be the amount received by gavyn
Caroline gets twice as much as Sarah
amount received by caroline = twice as much as Sarah
amount received by caroline = 2(amount received by sarah)
c = 2s ---- eqn 1
Sarah gets three times as much as Gavyn
amount received by sarah = three times as much as Gavyn
amount received by sarah = 3(amount received by gavyn)
s = 3g ------- eqn 2
Given that total amount is 980
c + s + g = 980 --- eqn 3
Let us solve eqn 1, 2, 3 to get values of "c" "s" "g"
From eqn 2,
[tex]g = \frac{s}{3}[/tex] --- eqn 4
Substitute eqn 1 and eqn 4 in eqn 3
[tex]2s + s + \frac{s}{3} = 980\\\\\frac{6s + 3s + s}{3} = 980\\\\6s + 3s + s = 980 \times 3\\\\10s = 2940\\\\s = 294[/tex]
Thus sarah has received £ 294
Final answer:
To solve for the amount Sarah receives, set up ratios based on the information provided and solve the resulting equation. The total amount divided among them is £980, which when divided by the total parts (10) gives Gavyn's share as £98. Sarah's share is three times Gavyn's share, resulting in £294.
Explanation:
The problem described is a classic division in ratio mathematics question where £980 is being divided among Caroline, Sarah, and Gavyn following certain rules.
According to the problem, Caroline receives twice the amount that Sarah receives and Sarah receives triple the amount that Gavyn receives.
We can set up the following ratios: C = 2S and S = 3G, where C stands for Caroline's amount, S for Sarah's, and G for Gavyn's. If we denote Gavyn's amount as G, then Sarah's amount is 3G and Caroline's is 2 × 3G which is 6G.
To find the value of G, we can write the equation G + 3G + 6G = £980 or 10G = £980. Solving for G gives us G = £98.
Therefore, Sarah, receiving three times as much as Gavyn, gets 3 × £98 = £294.

What is the area of the shaded region in the figure below? Leave answer in terms of pi and in simplest radical form.
Answer:
C. 54π + 20.25√3 cm²
Step-by-step explanation:
The shaded area can be split into two areas: a sector and an isosceles triangle.
Area of a sector is:
A = (θ/360°) πr²
where θ is the central angle and r is the radius.
Area of an isosceles triangle can be found with SAS formula:
A = ½ ab sin θ
where a and b are two sides of a triangle and θ is the angle between them.
In this case, r = a = b = 9 cm. The central angle of the sector is 240°, and the vertex angle of the triangle is 120°. Therefore, the total area is:
A = (240°/360°) π (9 cm)² + ½ (9 cm) (9 cm) sin 120°
A = 54π + 20.25√3 cm²

Hasn't worked two jobs last summer to start saving for a car he mowed lawns during the day and work at a pizza place in the evening with my cousin earn a total of $1400 if you earn 360 more at the pizza place the mowing one how much did he earn each job
Answer:
Hudson earned $520 in moving lawns and $880 by working in Pizza place.
Step-by-step explanation:
Given:
Total Money Earned = $1400
Let Money earned in moving lawns be 'x'
Also Given:
he earned $360 more at the pizza place than mowing lawns
Money Earned working at pizza place = [tex]x+360[/tex]
we need to find money earned in each job.
Now Total money earned is equal to sum of Money earned moving lawns and money earned working at pizza place.
Framing the equation we get;
[tex]x+x+360=1400[/tex]
Solving the equation we get;
[tex]2x+360 =1400\\\\2x = 1400-360\\\\2x =1040\\\\x=\frac{1040}{2}=\$520[/tex]
Money Earned working at pizza place = [tex]x+360 = 520 +360 = \$880[/tex]
Hence Hudson earned $520 in moving lawns and $880 by working in Pizza place.
Final answer:
To determine the earnings from each job, equations were set up using the total amount earned and the difference between the two earnings. The student earned $520 mowing lawns and $880 at the pizza place.
Explanation:
The student has provided information indicating that he worked two jobs and earned a combined total of $1400 over the summer. He earned $360 more at the pizza place than he did mowing lawns. To solve for how much he earned at each job, we need to set up two equations based on the given information. Let the amount earned mowing lawns be x and the amount earned at the pizza place be y.
From the information given, we have two equations:
x + y = $1400 (The total combined earnings) y = x + $360 (Earned $360 more at the pizza place than mowing lawns)Now we can substitute the second equation into the first to find how much he earned from each job. From the second equation, we have y = x + $360. Substituting this into the first equation gives us:
x + (x + $360) = $1400
Combining like terms gives us:
2x + $360 = $1400
Subtract $360 from both sides yields:
2x = $1040
Dividing both sides by 2 gives us:
x = $520
Therefore, the student earned $520 mowing lawns. To find how much was earned at the pizza place, we substitute x back into the second equation:
y = $520 + $360
So, the student earned $880 at the pizza place.
To estimate the length of the lake, caleb starts at one end of the lake and walk 95m. He then turns a 60° angle and walks on a new path and walks 8m more then arrives at the other end of the lake. Approximately how long is the lake?
Answer:
Length of the lake is 97.30 m
Step-by-step explanation:
We have given Caleb starts at one end of the lake and walk 95 m
So [tex]d_1=95m[/tex]
And then he turns at an angle of 60°
So [tex]\Theta =60^{\circ}[/tex] and then again walk 8 m
So [tex]d_2=8m[/tex]
We have to fond the total length of the lake , that is d
Total length of the lake is given by [tex]d=\sqrt{d_1^2+d_2^2+2d_1d_2cos\Theta }=\sqrt{95^2+8^2+2\times 95\times 8\times cos60^{\circ}}=97.30m[/tex]
So length of the lake is 97.30 m
Final answer:
Using the Law of Cosines with Caleb's path measurements of 95 meters and 103 meters at a 60-degree angle, the length of the lake is found to be approximately 104 meters.
Explanation:
To estimate the length of the lake, we can represent Caleb's path as a triangle, where the length of the lake forms one side of the triangle. Caleb starts by walking 95 meters along one side, then makes a 60° angle and walks 8 meters more than the length of the first path, forming the second side of the triangle. The length of the lake, which is the final side, can be calculated using the Law of Cosines.
The Law of Cosines is given by c² = a² + b² - 2ab×cos(γ), where γ is the enclosed angle and a, b, and c are the lengths of the sides of the triangle.
In this case, a = 95m, b = 95m + 8m = 103m, and γ = 60°. Plugging these values into the Law of Cosines, we will find the length of the lake (c).
c² = 95² + 103² - 2×95×103×cos(60°)
c² = 9025 + 10609 - 19570×0.5
c² = 9025 + 10609 - 9785
c² = 10849
c ≈ √10849
c ≈ 104.16 meters
Therefore, the length of the lake is approximately 104 meters long.
If there were 400 foreclosures this year and 500 last year what is the percent of change?
Answer:
-20% ?
Step-by-step explanation:
I'm not sure but 2% of 5 is 1 so 20% of 500 is 100. so minus 20% would give you 400.
To find the percent of change in foreclosures, subtract the new number from the old number, divide by the old number, and multiply by 100. The foreclosures went from 500 to 400, resulting in a 20 percent decrease.
To calculate the percent of change in the number of foreclosures from one year to the next, you take the difference in the numbers (new number - old number), divide by the old number (the number from the earlier year), and then multiply the result by 100 to obtain a percentage. In this case, there were 500 foreclosures last year and 400 this year. Therefore, the calculation is as follows:
(Old Number - New Number) / Old Number × 100 = Percent Change
(500 - 400) / 500 × 100 = 100 / 500 × 100
0.2 × 100 = 20%
There has been a 20 percent decrease in foreclosures from last year to this year.

Worldwide quarterly sales of a brand of cell phones were approximately q = −p + 126 million phones when the wholesale price was $p. (a) If the cellphone company was prepared to supply q = 9p − 354 million phones per quarter at a wholesale price of $p, what would have been the equilibrium price? $ 48 Correct: Your answer is correct. (b) The actual wholesale price was $43 in the fourth quarter of 2004. Estimate the projected shortage or surplus at that price. HINT [See Example 4.] There is an estimated Correct: Your answer is correct. of Incorrect: Your answer is incorrect. million phones.
Answer:
a) equilibrium price = $48
b) shortage of 50 million phones
Step-by-step explanation:
Quarterly sales of a brand/quantity demanded (q) =
-p+126 million phones
a) if supply(q) = 9p - 354 million phones, at equilibrium quantity demanded = quantity supplied
-p + 126 = 9p - 354
-p - 9p = -354 - 126
-10p = -480
p = -480/-10
p = $48
The price at equilibrium = $48
b) actual wholesale price in the fourth quarter of 2004= $43
Quantity demanded = -p + 126
= -43 + 126
= 83 million phones
Quantity supplied = 9p - 354
= 9(43) - 354
= 387 - 354
= 33 million phones
Since quantity supplied is less than quantity demanded, there will be a shortage.
Shortage = 83 -33
= 50 million phones
The equilibrium price is determined to be $48 by equating the demand and supply. At an actual price of $43, there is a shortage of 50 million phones. This is found by comparing the quantities demanded and supplied at that price.
Equilibrium Price and Surplus/Shortage Estimation
We are given the demand and supply functions for cell phones, where the demand function is q = −p + 126 and the supply function is q = 9p − 354. To find the equilibrium price, we set the demand function equal to the supply function:
−p + 126 = 9p − 354Solving for p:
126 + 354 = 9p + p480 = 10pp = 48Hence, the equilibrium price is $48.
For part (b), we need to estimate the shortage or surplus at an actual wholesale price of $43. We substitute p = 43 into both demand and supply functions:
Demand: qd = −43 + 126 = 83 million phonesSupply: qs = 9(43) − 354 = 387 − 354 = 33 million phonesTherefore, there is a shortage of 83 - 33 = 50 million phones at the price of $43.

In the rectangular coordinate system, points (4,0) and (–4,0) both lie on circle C. What is the maximum possible value of the radius of C ?
Answer:
There is no finite maximum value of the radius of C.
Step-by-step explanation:
We have been given that in the rectangular coordinate system, points (4,0) and (–4,0) both lie on circle C. We are asked to find the maximum possible value of the radius of C.
If the center of the circle C would have been at origin (0,0), then the radius of the circle C would be 4 units.
Since there is no information given about center of circle, so radius can be infinitely long. Therefore, there is no finite maximum value of the radius of C.

Answer:
The 10% off sale will save Melissa $10.49.
Step-by-step explanation:
Given:
The listed price of the camera is $195.99.
The camera is no sale for 10% off and Melissa has a coupon for 5% off the sales tax is 7%.
Now, to find the money Melissa will save of the 10% off sale.
So, to get the price of camera of the 5% off sale:
[tex](195.99-5\%\ of\ 195.99)[/tex]
[tex]=(195.99-\frac{5}{100}\times 195.99)[/tex]
[tex]=(195.99-9.80)[/tex]
[tex]=186.19[/tex]
Now, adding the sales tax:
[tex]186.19+7\%\ of\ 186.19[/tex]
[tex]=186.19+\frac{7}{100} \times 186.19[/tex]
[tex]=186.19+13.03[/tex]
[tex]=199.22[/tex]
Thus, the price is $199.22.
Now, to get the price of 10% off sale:
[tex]195.99-10\%\ of\ 195.99[/tex]
[tex]=195.99-\frac{10}{100} \times 195.99[/tex]
[tex]=176.39[/tex]
So, adding sales tax:
[tex]176.39+7\%\ of\ 176.39[/tex]
[tex]=176.39+\frac{7}{100} \times 176.39[/tex]
[tex]=188.73[/tex]
Hence, the price is $188.73.
Now, to get the money 10% off sale will save Melissa:
[tex]199.22-188.73[/tex]
[tex]=10.49[/tex]
Therefore, the 10% off sale will save Melissa $10.49.
Final Answer:
The 10% off sale will save Melissa approximately $19.60.
Explantion:
To calculate the savings from the 10% off sale on the listed price of the digital camera, follow these steps:
1. Determine the listed price of the camera. In this case, the listed price is $195.99.
2. Calculate the discount amount by multiplying the listed price by the discount percentage (expressed as a decimal). For a 10% discount, you would convert that percentage to a decimal by dividing by 100:
10% = 10/100 = 0.10.
3. Multiply the listed price by the decimal form of the discount percentage to find the savings:
Savings = Listed Price × Discount Percentage
Savings = $195.99 × 0.10
4. Calculate the actual savings:
Savings = $195.99 × 0.10 = $19.599
5. Since savings are typically represented in dollar format (rounded to two decimal places), we round the savings to the nearest cent:
Savings ≈ $19.60
So, the 10% off sale will save Melissa approximately $19.60.

Monthly cost for 7 slices: Monthly cost for x x slices:
Evan would have to pay $10.50 to the pizza shop if he bought 7 slices of pizza. The monthly cost for x slices of pizza would be $1.50x.
Explanation:Evan purchased a membership to a pizza shop that has a membership program for frequent buyers. The membership costs $5 per month and members get a discounted price of $1.50 per slice of pizza. If Evan bought 7 slices of pizza this month, he would have to pay $1.50 per slice, since he is a member. Therefore, Evan would have to pay 7 x $1.50 = $10.50 to the pizza shop.
The monthly cost for x slices of pizza can be calculated by multiplying the cost per slice ($1.50) by the number of slices (x). So, the monthly cost for x slices would be x x $1.50 = $1.50x.

The height of a curved support can be modeled by
f(x) = x^2/256 + 16
Find the width of the beam
Answer:
128
Step-by-step explanation:
I assume there's a negative sign missing, since the image is a downwards parabola.
f(x) = -x²/256 + 16
The width of the beam is the distance between the x-intercepts.
0 = -x²/256 + 16
x²/256 = 16
x² = 4096
x = ±64
So the width is:
64 − (-64) = 128
what is the difference between Compound Interest and simple interest???
Answer:
Simple interest is calculated using initial principle while compound interest is calculated considering the interest also .
Step-by-step explanation:
Interest is the cost of borrowing money, where the borrower pays a fee to the lender for using his money. The interest, typically expressed as a percentage, can either be compounded or simple .
Simple interest is based on the principal amount , while compound interest is based on the principal amount and the interest that adds onto it in every period and the final principle is used for calculating the interest.
Simple interest is calculated on the principal amount of a loan and it's easier to find out than compound interest.

First of all, have to find gradient using the formula above :
(2,4) & (14,-2)
m = (-2-4) / (14-2)
= -6 / 12
= -1/2
Second, using y = mx + b as b is a constant and is a y-intercept. Using any of these 2 coordinates to find the value of b with given gradient :
y = mx + b
Let y=4 & x=2
4 = (-1/2)(2) + b
b = 4 + 1
= 5
Lastly, put the value of gradient and y-intercept into the equation :
y = mx + b
Let m=-1/2 & b=5
y = (-1/2)x + 5

The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated up.d. The graph of the new line is less steep than the graph of the original line, and they-intercept has been translated down.
Answer:
b. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up
Option b is right.
Step-by-step explanation:
Given that linear function f(x)=x is graphed on a coordinate plane.
The graph of a new line is formed by changing the slope of the original line to 2/3 and the y-intercept to 4.
The original slope was 1. Now changed to 2/3 i.e. slope is reduced. Hence the new line will be less steeper.
Also original line y =x has y intercept at the origin.
By changing y intercept to 4, we changed y intercept to upwards by 4 units.
Thus there is a vertical shift of 4 units.
b. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up
Option b is right.
A linear function is represented by a straight line.
The true statement is: (b) the graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up.
The function f(x) is given as:
[tex]\mathbf{f(x) = x}[/tex]
The attributes of the new function are:
Slope = 2/3y-intercept = 4So, the new function is:
[tex]\mathbf{f'(x) = \frac23x + 4}[/tex]
The slope of [tex]\mathbf{f(x) = x}[/tex] is 1.
2/3 is less than 1.
So, the new line is less steep
The y-intercept (4) means that:
The new line is shifted up by 4 units
Hence, the correct statement is: (b)

Project B: A 10-inch by 8-inch blueprint with a scale of 1 inch to 8 feet and a projected cost of $25,000. Project C: A 15-inch by 12-inch blueprint with a scale of 1 inch to 6 feet and a projected cost of $27,000. Project D: An 8-inch by 6-inch blueprint with a scale of 1 inch to 12 feet and a projected cost of $30,000. Order the projects from greatest to least projected cost per square foot of the actual offices. Project C Project B Project D Project A
Answer:
Cost in decreasing order: Project B>Project A>Project D>Project C
Step-by-step explanation:
Project A
Area: [tex]A=20 in*15 in= 300 in^2[/tex]
Scale: [tex]S=\frac{4 ft *4ft}{1 in*1in}=16 \frac{ft^2}{in^2}[/tex]
Cost:
[tex]C=\frac{22000}{300 in^2*16 \frac{ft^2}{in^2}}[/tex]
[tex]C=\frac{4.58}{ft^2}[/tex]
Project B
Area: [tex]A=10 in*8 in= 80 in^2[/tex]
Scale: [tex]S=\frac{8 ft *8ft}{1 in*1in}=64 \frac{ft^2}{in^2}[/tex]
Cost:
[tex]C=\frac{25000}{80 in^2*64 \frac{ft^2}{in^2}}[/tex]
[tex]C=\frac{4.88}{ft^2}[/tex]
Project C
Area: [tex]A=15 in*12 in= 180 in^2[/tex]
Scale: [tex]S=\frac{6 ft *6ft}{1 in*1in}=36 \frac{ft^2}{in^2}[/tex]
Cost:
[tex]C=\frac{27000}{180 in^2*36 \frac{ft^2}{in^2}}[/tex]
[tex]C=\frac{4.16}{ft^2}[/tex]
Project D
Area: [tex]A=8 in*6 in=48 in^2[/tex]
Scale: [tex]S=\frac{12 ft *12ft}{1 in*1in}=144 \frac{ft^2}{in^2}[/tex]
Cost:
[tex]C=\frac{30000}{48 in^2*144 \frac{ft^2}{in^2}}[/tex]
[tex]C=\frac{4.34}{ft^2}[/tex]
Which correlation coefficient best represents a moderate relationship showing fewer anxiety symptoms in people who report higher life satisfaction? –0.5 +0.7 –0.2 +0.4
Answer:
-0.5
Step-by-step explanation:
The correlation coefficient represents the relationship between two variables and here two variables are anxiety symptoms and life satisfaction. As it is mentioned in the statement that less anxiety symptoms are present in the individuals who have higher life satisfaction, so there is negative/ inverse relationship between anxiety symptoms and life satisfaction. Just to be clear the inverse relationship means that increase in one variable lead to decrease in second variable and vice versa. Also according to rule of thumb 0.5 represents the moderation correlation because correlation coefficient ranges from -1 to +1 and 0.5 is a middle value. So the correlation coefficient in the given scenario is -0.5.
Kira goes running Monday, Wednesday, and Friday of each week. Each Monday she runs 2.5 miles, each Wednesday she runs 5.75 miles, and each Friday she runs 7.75 miles. How many total miles does she run in 9 weeks
Kira runs 144 miles in 9 weeks.
Step-by-step explanation:
Given,
Distance ran on Monday = 2.5 miles
Distance ran on Wednesday = 5.75 miles
Distance ran on Friday = 7.75 miles
Distance ran in one week = 2.5+5.75+7.75 = 16 miles
Distance ran in 9 weeks = Number of weeks * Distance ran in one week
Distance ran in 9 weeks = 16*9 = 144 miles
Kira runs 144 miles in 9 weeks.

*trigonometry and area.*
Find the area of a regular octagon with a side length of 8cm. Round to the nearest tenth.
Answer:
The correct answer is that the area of the regular octagon is 309 cm²
Step-by-step explanation:
There are several formulas for calculating the area of a regular octagon. We will use this one for solving this question because it does not require additional information .
Area = (2 * s²)/tan 22,5°
s = 8 cm
Replacing with the real values, we have:
Area = (2 * 8²)/tan 22,5°
Area = 2 * 64/0.4142
Area = 128/0.4142
Area = 309 cm² (Rounding to the nearest tenth)
