11x+14y=13
11x+10y=25

Answer:

  y = -1/6x +2

Step-by-step explanation:

The black vertical line in the middle of the graph is the y-axis. The blue line crosses it a the point marked 2. This is known as the y-intercept.

The slope of the line is the ratio of "rise" (vertical change) to "run" (horizontal change).

There is a marked point on the line at the y-intercept, where x=0 and y=2. There is another marked point to the right of that, where x=6 and y=1.

The vertical change between those two points is 1 -2 = -1.

The horizontal change between those two points is 6 -0 = 6

The slope is then -1/6.

__

The slope-intercept form of the equation of a line is often written as ...

   y = mx + b

where "m" is the slope (-1/6), and "b" is the y-intercept.

Using the values we found above, the equation of the line is ...

  y = -1/6x +2

Answer:

2 1/6 chapters per hour

Step-by-step explanation:

Find the unit rate, as follows:

   9.75 chapters

 ----------------------- = 2.166666 ... chapters per hour, or

     4.5 hours                            2 1/6 chapters per hour

The unit rate in chapters per hour is 13/6.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Chang reads 9 3/4 chapters in 4 1/2 hours.

So, the unit rate of reading is

= 9 3/4 / (4 1/2)

= (39/4) / (9/2)

= 39/4 x 2/9

= 13/2 x 1/3

= 13/6.

Hence, the unit rate is 13/6.

Answer:

x = 3/2 + root(3)/2  or  x = 3/2 - root(3)/2

In vertex form the equation is  y = (x - 3/2)^2 + 3/4

Step-by-step explanation:

y = x^2 - 3x + 3

y = x^2  - 3x  + 9/4  - 9/4 + 3

y = (x - 3/2)^2  + 3/4

I think you want to find the roots to the equation, right?

so  

y = (x - 3/2)^2  + 3/4 = 0

(x - 3/2)^2 = -3/4

x - 3/2 =  root(-3/4)

x = 3/2 + root(3)/2  or  x = 3/2 - root(3)/2

The total cost of an order of n concert tickets, with each ticket costing $35 and a fixed processing charge of $15, is represented by the expression 35n + 15.

To represent the total cost of an order of n number of tickets, we need to account for the cost of each ticket as well as the processing charge that applies to the entire order. The cost of one ticket is $35, and thus for n tickets, the total cost for the tickets alone would be 35n dollars. Since the processing charge is a fixed amount per order, not dependent on the number of tickets, we add the flat fee of $15 to the cost of the tickets. Therefore, the expression for the total cost of the order is 35n + 15.

Answer

The student ate 72ounces of fruit snacks

Explanation

If there are 20packs of fruit snacks in a box and each pack weighs 6 ounces, the total weight of 20packs will be 20×6 = 120ounces

If there are 48 ounces of fruit snacks left in the box after student has eaten some, the amount of ounces of fruit eaten by the student will be:

Total number of ounces of 20packs - weight of left over snacks

= 120-48

= 72ounces

The students ate 72 ounces of fruit snacks.

First, we need to calculate the total weight of the fruit snacks when the box is full. Since there are 20 packs in a box and each pack weighs 6 ounces, the total weight of a full box is:

[tex]\[ 20 \text{ packs} \times 6 \text{ ounces/pack} = 120 \text{ ounces} \][/tex]

Next, we are given that there are 48 ounces of fruit snacks left in the box after the students have eaten some. To find out how many ounces were eaten, we subtract the remaining weight from the total weight of a full box:

[tex]\[ 120 \text{ ounces} - 48 \text{ ounces} = 72 \text{ ounces} \][/tex]

Therefore, the students ate 72 ounces of fruit snacks.

The students ate 72 ounces of fruit snacks.

Answer:

The ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

Step-by-step explanation:

The height of a right circular cylinder is 1.5 times the radius of the base.

Let the radius of base be x

So, Height of a right circular cylinder = 1.5x

Total surface area of cylinder =[tex]2 \pi r h + 2 \pi r^2 = 2 \pi r(h+r)=2 \pi \times x(x+1.5x)=2 \pi \times x \times 2.5x[/tex]

Curved surface area of cylinder = [tex]2 \pi rh = 2 \pi \times x \times 1.5 x[/tex]

So, Ratio of the total surface area to the lateral (curved) surface area of the cylinder = [tex]\frac{2 \pi \times x \times 2.5x}{2 \pi \times x \times 1.5 x}=\frac{2.5}{1.5}=\frac{25}{15}=\frac{5}{3}[/tex]

Hence the ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

Answer:

$3125

Step-by-step explanation:

[tex]A = P(1 + \frac{r}{100} )^{n}[/tex]

A = 250(1 + 0.25)ⁿ

A = (312.5)ⁿ

n = 10

A = $3125

A = I

After converting the annual nominal interest rate to decimal and applying the values, the calculated interest earned on a principal of $250.00 at 4% over 2 years is $20.00.

The student is asking how to find the missing value of interest earned (I) given the principal (P), the annual nominal interest rate (r), and the time (t) in years when the interest is not compounded.

The formula for simple interest is I = P x r x t.

In this example, you'll need to convert the percentage into a decimal.

Hence, the annual nominal interest rate of 4% is written as 0.04 in decimal form.

Now, let's calculate the interest earned over 2 years on a principal of $250.00 at a rate of 4% per year.

I = P x r x t

I = $250.00 x 0.04 x 2

I = $250.00 x 0.08

I = $20.00

Therefore, the missing value of interest earned (I) after 2 years is $20.00.

Step-by-step explanation:

I'm not entirely sure this is right but it's what i got.

The distance from the center of dilation to the midpoint of B'C' is 4 times the original distance from the center to the midpoint of BC, given the dilation scale factor is 4.

To find the distance from the center of dilation to the midpoint of B'C', we use the properties of dilations in geometry. Since triangle ABC is dilated with a scale factor of 4, every length in triangle ABC is multiplied by 4 to get the corresponding length in triangle A'B'C'. If the original distance from the center of dilation (the origin) to the midpoint of BC was 'x', then after the dilation, the distance from the center (the origin) to the midpoint of B'C' is 4x. If the original distance x is known, we calculate the dilated distance by multiplying x by the scale factor of 4.

when you square the 4, you get 16

16 x 3.14 is 50.24

Answer:

Step-by-step explanation:

The question is incomplete as the table that shows the data distribution is missing.

However, the table is as follows:

Fruit ------------- Frequency

Apple ------------ 10

Orange ---------- 13

Banana ---------- 24

Pineapple ------- 5

Watermelon ---- 8

To accurately draw a pie chart; first, the total frequency or population must be calculated.

Total = 10 + 13 + 24 + 5 + 8

Total = 60

Then the portion which each fruit will take in the pie chart is also calculated.

This is calculated by

(Frequency * 360)/Total;

For Apple

Apple = (10 * 360)/60

Apple = 3600/60

Apple = 60°

For Orange

Orange = (13 * 360)/60

Orange = 4680/60

Orange = 78°

For Banana

Banana = (24 * 360)/60

Banana = 8640/60

Banana = 144°

For Pineapple

Pineapple = (5 * 360)/60

Pineapple = 1800/60

Pineapple = 30°

Lastly,

For Watermelon

Watermelon = (8 * 360)/60

Watermelon = 2880/60

Watermelon = 48°

After this has been done, the final step is to plot these data on a pie chart.

Answer:

Area of shaded region/area of square = [tex]\pi[/tex]/8

[tex]\frac{50\pi cm^2 }{400 cm^2} = \frac{1}{8}[/tex]

Area of the semi-circle: 50[tex]\pi[/tex] cm^2

Step-by-step explanation: The problem asked us to prove that the area of the shaded region within the diagram divided by the area of the square equals 1/8. An image will be provided down below for visual representation.

First, we must figure out the area of the shaded region. We do this by finding the area of the semi-circle inside the arc circle that goes A to C.

Area of a semi-circle (diameter): [tex]A = \frac{\pi * d^2}{8}[/tex]

[tex]A = \frac{\pi *(20)^2}{8}[/tex]

[tex]A = 50\pi cm^2[/tex]

Now to find the area of the shaded region, we must subtract the area of the semi-circle from the area that covers the arc circle AB.

In the diagram, we can see that the arc circle within the square looks like a quarter circle. We need to manipulate the equation to highlight this.

Area of a semi-circle (radius) divided by 4  = [tex]A = \frac{\pi *r^2}{4}[/tex]

[tex]A = \frac{\pi *20^2}{4} \\A = 100\pi\\A = 100\pi - 50\pi \\A = 50\pi cm^2[/tex]

Area of a square = [tex]A = s^2[/tex]

[tex]A = (20)^2[/tex]

A = 400 cm^2

Now we take these two solutions to see if it equal [tex]\frac{\pi }{8}[/tex].

[tex]\frac{50\pi }{400} \\\frac{50*\pi }{50*8} = \frac{\pi }{8}[/tex]

That is how we get to our final answer: [tex]\frac{\pi }{8}[/tex]

d ≤ 95

Step-by-step explanation:

The inequality that states we have at most 95 days is d≤ 95.

A connection between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

The inequality can be resolved by adding the same amount to each side, subtracting the same amount from each side, multiplying or dividing each side by the same positive integer, and more. If you multiply or divide either side by a negative value, you must flip the inequality sign.

If d represents how many days are left in school this year.

And we have at most 95 days.

Then,

d can not be more than 95.

d ≤ 95

Therefore, the inequality is d ≤ 95.
