To calculate the sale price of the sweatshirt, multiply the original price by the discount rate to get the discount amount and subtract from the original price. The sweatshirt is now priced at $24.
Explanation:We can find the amount discounted by multiplying the original price of the sweatshirt by the discount rate. So, we calculate 60% of $60. First distinguish that 60% is the same as 0.60 in decimal form. Therefore, we multiply $60 by 0.60 (60%) to get $36. This is the amount that is discounted from the original price. To find the new price after discount, subtract this amount from the original price. So, $60 - $36 equals $24. Therefore, the sweatshirt on sale is now priced at $24.

Step-by-step explanation:
The shadow of a moon during a solar eclipse travels 2,300 miles in 1 hour. In the first 20 minutes, the shadow traveled 766 and 2/3 miles. How long does it take the shadow to travel 1,150 miles?
Answer:
30 minutes
Step-by-step explanation:
Let
y ---> the distance in miles
x ---> the time in minutes
Remember that
[tex]1\ h=60\ min[/tex]
[tex]766\frac{2}{3}\ mi=\frac{766*3+2}{3}=\frac{2,300}{3}\ mi[/tex]
we have the ordered pairs
[tex](20,\frac{2,300}{3}),(60,2,300)[/tex]
Find the slope
[tex]m=(2,300-\frac{2,300}{3})/(60-20)[/tex]
[tex]m=(\frac{4,600}{3})/(40)[/tex]
[tex]m=\frac{4,600}{120}\\\\m=\frac{115}{3}\ mi/min[/tex]
Find the linear equation in point slope form
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=\frac{115}{3}[/tex]
[tex]point\ (60,2,300)[/tex]
substitute
[tex]y-2,300=\frac{115}{3}(x-60)[/tex]
[tex]y-2,300=\frac{115}{3}x-2,300\\\\y=\frac{115}{3}x[/tex]
Is a proportional relationship between the variables x and y (speed)
For y=1,150 miles
substitute the value of y in the linear equation and solve for x
[tex]1,150=\frac{115}{3}x\\\\x=1,150(3)/115\\\\x=30\ minutes[/tex]
Final answer:
It takes approximately 30 minutes for the shadow to travel 1,150 miles during a solar eclipse.
Explanation:
To determine the time it takes for the shadow to travel 1,150 miles, we can set up a proportion using the given information. Let's call the time it takes to travel 1,150 miles 't'. We can set up the proportion:
766.67 miles / 20 minutes = 1,150 miles / t
Now, let's solve for 't'. We can cross-multiply:
766.67 * t = 20 * 1,150
Divide both sides by 766.67:
t = (20 * 1,150) / 766.67
Simplifying the right side of the equation gives us:
t ≈ 30
Therefore, it takes approximately 30 minutes for the shadow to travel 1,150 miles.

in the diagram,MNO is a right angled triangle,Mn=13 cm and MN is 5 cm. Find the value of x
Answer:
x = 12
Step-by-step explanation:
Pythagoras' Theorem
[tex]a^{2} = b^{2} + c^{2}[/tex]
a = 13
b = 5
c = x
[tex]13^{2} = 5^{2} + x^{2}\\169 = 25 + x^{2}\\169 - 25 = x^{2}\\144 = x^{2}\\12 = x[/tex]
After applying the Pythagorean theorem on the given right-angled triangle the value of x we get 12.
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
The Pythagoras theorem for a right-angled triangle:
(Hypotenuse)²= (Perpendicular)² + (Base)²
For the given triangle:
The hypotenuse 'MC' = 13
The perpendicular 'MN' = 5
Base 'NC' = x
Substituting these values into the Pythagorean theorem:
(13)²= (5)² + (x)²
Simplifying the square,
169 = 25 + x²
Subtracting 25 we get,
x² = 144
Take square root on both sides,
x = 12
Hence,
The value of x is 12.

Mr. Wilson owes $288.40 on his credit card. He would like to make 4 equal payments. How much will each payment be?
Each of the 4 payments made by Mr. Wilson will be $72.10.
How much will each payment be?
From the question, we have the following parameters that can be used in our computation:
Amount owed = $288.40
Number of payments = 4
To calculate the amount of each payment, we can divide the total amount owed by the number of payments:
Amount per payment = Total amount owed / Number of payments
Substitute the known values into the equation
Amount per payment = $288.40 / 4 =
Amount per payment = $72.10
Hence, each payment will be $72.10.

Laura made $324 for 18 hours of work at the same rate, how much would he make for 8 hours of work
Final answer:
Laura earns $18 per hour, and for 8 hours of work, she would make $144.
Explanation:
The question asks us to determine how much Laura would make for 8 hours of work, given that she made $324 for 18 hours of work. To find the hourly rate, we divide the total amount earned by the total hours worked. Then we multiply the hourly rate by the number of hours we want to find the earnings for.
To calculate Laura's hourly rate: $324 / 18 hours = $18 per hour.
Now, we can find out Laura's earnings for 8 hours: $18 per hour * 8 hours = $144.
Therefore, Laura would make $144 for 8 hours of work at the same rate.
which of the following graphs represents a quadratic function f(x)=(x-3)^2+5
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
[tex]f(x)=(x-3)^2+5[/tex]
This is a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (3,5)
The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex
so
[tex]x=3[/tex] ---> axis of symmetry
Find the y-intercept (value of f(x) when the value of x is equal to zero)
For x=0
[tex]f(x)=(0-3)^2+5=14[/tex]
The y-intercept is the point (0,14)
Find the x-intercept (values of x when the value of f(x) is equal to zero)
For y=0
[tex]0=(x-3)^2+5[/tex]
[tex](x-3)^2=-5[/tex] ---> has no real solutions
The function has no x-intercepts (The roots of the quadratic equation are complex numbers)
therefore

The data to represent average test scores for a class of 16 students includes an outlier value of 72. If the outlier is included, then the mean is 86. Which statement is always true about the new data when the outlier is removed?
a.) The mean would increase.
b.) The mean would decrease.
c.) The median would increase.
d.) The median would decrease.
Answer:
Step-by-step explanation:
when the outlier is removed, the mean increases.....the removing of the outlier does very little to the median or mode.
example :
1,2,3,4,5
mean = 15/5 = 3......median = 3
now throw in an outlier..
1,2,3,4,5,50
mean = 65/6 = 10 5/6.....median = (3 + 4) /2 = 7/2 = 3.5
as u can see, it drastically affects the mean...and does little to the median

You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page of science and 0.8 of a minute to read each page of the play. How much time do you spend reading?
CLEAR
The time spent for reading is 31.3 minutes
Solution:
You read 9.75 pages in your science book and 24.5 pages of a play for English class
Therefore,
Number of pages read in science = 9.75
Number of pages read in play = 24.5
Also given that,
Time taken to read each page of science = 1.2 minutes
Time taken to read each page of play = 0.8 minute
To find: Time spent for reading
Time spent for reading = Number of pages read in science x Time taken to read each page of science + Number of pages read in play x Time taken to read each page of play
[tex]Time\ spent\ for\ reading = (9.75 \times 1.2) + (24.5 \times 0.8)\\\\Time\ spent\ for\ reading = 11.7 + 19.6\\\\Time\ spent\ for\ reading = 31.3[/tex]
Thus time spent for reading is 31.3 minutes
The diagram shows the outline of a dining room with a bay window. Explain how to find the area of the room.
Answer: Divide the room into two figures (a rectangle and a trapezoid), then find the area of both figures and add them in order to calculate the area of the dining room.
Step-by-step explanation:
Divide the room into two figures: a rectangle and a trapezoid (as you can observe in the picture attached).
You need to find the area of the trapezoid and the area of the rectangle and then add them. This sum will be the area of the dining room.
First, you need to remember that:
1. The area of a rectangle can be calculated with this formula:
[tex]A_r=lw[/tex]
Where "l" is the lenght and "w" is the width of the rectangle.
2. The following formula is used to calculate the area of a trapezoid:
[tex]A_t=h(\frac{B+b}{2} )[/tex]
Where "B" and "b" are the bases of the trapezoid and "h" is the height of the trapezoid.
Therefore, the area of the dining room will be:
.[tex]A_{room}=A_r+A_t\\\\A_{room}=lw+h(\frac{B+b}{2} )[/tex]
Answer:
Break the figure into two rectangles and two triangles. Find the area of each using the formulas A=bh and A=1/2bh. The sum of the areas is the area of the dining room.
Step-by-step explanation:
Break the figure into two rectangles and two triangles. Find the area of each using the formulas A=bh and A=1/2bh. The sum of the areas is the area of the dining room.

A dog store has 3 female Chihuahuas. 14 of the 25 dogs at the store are not Chihuahuas. What is the probability that a dog selected at random is female, given it is a Chihuahua?
Answer 3/11
Answer:
Answer C
Step-by-step explanation:
The probability that a randomly selected dog is female, given it is a Chihuahua, is 3/11. This is calculated by dividing the number of female Chihuahuas (3) by the total number of Chihuahuas (11) in the store.
Explanation:Probability of Selecting a Female Chihuahua
First, let's determine the total number of Chihuahuas in the store. Since the store has 25 dogs and 14 of them are not Chihuahuas, we subtract 14 from 25 to get the number of Chihuahuas:
25 - 14 = 11
There are 11 Chihuahuas in the store. We are given that there are 3 female Chihuahuas. Therefore, the probability that a randomly selected dog is a female Chihuahua is the number of female Chihuahuas divided by the total number of Chihuahuas:
Probability = Number of Female Chihuahuas / Total Number of Chihuahuas = 3 / 11
This calculation gives us the probability of 3/11 that a dog selected at random is female, given it is a Chihuahua.

paula riddle charges $2.25 per hour to babysit before 9 pm and $2.75 per hour after 9 pm. if she babysits from 6 pm to 11 pmhow much will she earn?
Answer:
The Total earning of Paula riddle from 6 pm to 11 pm is $7.25
Step-by-step explanation:
Given as :
Paula riddle charges per hour before 9 pm = $2.25 per hour
Paula riddle charges per hour after 9 pm = $2.75 per hour
Let The Total earning of Paula riddle from 6 pm to 11 pm = $A
Now, According to question
∵ before 9 pm , charges = $2.25 per hour
The time spend between 6 pm to 9 pm = 3 hours
So, The charge between 6 pm to 9 pm = $2.25 per hours × 3 hours
i.e The charge between 6 pm to 9 pm = $6.75
Again
After 9 pm , charges = $2.75 per hour
The time spend between 9 pm to 11 pm = 2 hours
So, The charge between 9 pm to 11 pm = $2.75 per hours × 2 hours
i.e The charge between 9 pm to 11 pm = $5.5
So, The Total earning of Paula riddle from 6 pm to 11 pm = charge between 6 pm to 9 pm + charge between 9 pm to 11 pm
i.e A = $6.75 + $5.5
Or, A = $7.25
So, The Total earning of Paula riddle from 6 pm to 11 pm = A = $7.25
Hence, The Total earning of Paula riddle from 6 pm to 11 pm is $7.25 Answer
Answer:

{x - y = -2
Answer:
See attachment
Step-by-step explanation:
The given system is
2x-y=4
x-y=-2
We write the system in slope-intercept form:
y=2x-4
y=x+2
The first equation has slope of 2 and y-intercept at (0,-4)
When y=0, x=2.
We plot (0,-4) and (2,0) to graph this first equation.
The second equation has a slope of 1 and a y-intercept at (0,2)
Also when y=0, x=-2.
We plot (0,2) and (-2,0) and draw a straight line through them.
The graph of the system is shown in the attachment.
