Answer: the answer is (D) A′(0, 0), B′(−5, −2), C′(−5, 5), D'(0, 3).
Step-by-step explanation: To rotate the polygon 180°, we need to reflect each point over the line passing through the origin and perpendicular to the x-axis.
The point (0,0) will remain the same as it is the origin and the line of reflection passes through it.
To find the coordinates of B', we reflect the point (5,2) over the line to get (-5,-2), then we translate it 5 units to the left to get (-5+5, -2) = (-2, -5).
To find the coordinates of C', we reflect the point (5,-5) over the line to get (-5,5), then we translate it 5 units to the left to get (-5+5, 5) = (0, 5).
To find the coordinates of D', we reflect the point (0,-3) over the line to get (0,3).
Therefore, the coordinates of A', B', C', and D' are:
A' = (0,0)
B' = (-2,-5)
C' = (0,5)
D' = (0,3)
So the answer is (D) A′(0, 0), B′(−5, −2), C′(−5, 5), D'(0, 3).

Three softball players discussed their batting averages after a game.
Probability
Player 1 four sevenths
Player 2 six tenths
Player 3 five ninths
Compare the probabilities and interpret the likelihood. Which statement is true?
Player 1 is more likely to hit the ball than Player 2 because P(Player 1) > P(Player 2).
Player 3 is more likely to hit the ball than Player 1 because P(Player 3) > P(Player 1).
Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1).
Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2).
The table shows the prices of two types of juice. How much does each type of juice cost per gallon? There are 4 quarts in a gallon.
Answer:
Since there are 4 quarts in a gallon, we can convert Peach’s volume to gallons by dividing 1.5 quarts by 4 quarts/gallon which gives us 0.375 gallons.
Therefore, Orange juice costs $6.50 per gallon and Peach juice costs $12.00 per gallon.

Step-by-step explanation:
you currently have 225$ in your bank account you make withdrawals of 445$ and 30$ and then deposit 90$ what is the balance of the account now? Please thank you so much
Answer: -$160
Step-by-step explanation:
Start with $225
withdrawal means subtract $445
225-445 = - 220
you are now in negatives because you took more than you had
you take out another $30
-220 - 30 = -250 you are even more negative because you took out more
but you deposit, put back $90, means add
-250 +90 = -160 you are still negative because you didn't put back enough
-$160
The table shows the cost, c, of making different numbers of shirts, t. Create an equation to model the cost.
Number of Shirts, t 100 250 500
Cost to Company, c $600.00 $1,387.50 $2,700.00
Answer: c=(5.25)t+75
Step-by-step explanation:
To solve this problem, we need to think of this as a graph. First, we find the slope of our two coordinate points. There are three given: (100,600) (250,1387.5) and (500,2700)
We know that the number of shirts will be x in this equation because it is the independent variable. The cost to the company depends on the number of shirts made.
I like to choose whole numbers because they are the easiest to work with. Therefore, I will choose the coordinates (100,600) and (500,2700)
Now we use the slope formula:
2700-600/500-100
=2100/400
=5.25
To check to make sure that the slope is consistent throughout, we can look at our other coordinate: (250,1387.5)
Use the slope formula to check:
1387.5-600/250-100
=787.5/150
=5.25
Now we know that we have a consistent slope, the next step is to find the y-intercept.
(You could also use the point-slope formula, which would give you the entire equation outright. Although it is faster, there is more potential for an accidental mistake, so I like to use this method, although this method will be a bit slower.)
To find the y-intercept with a slope and point, use the equation y=mx+b.
y=(5.25)x+b
Now we can take a point and substitute it in. I'm going to use the point (100,600) as it is the easiest one.
600=5.25(100)+b
600=525+b
b=600-525
=75
Therefore, the equation is c=(5.25)t+75.

The frequency of grades earned on a Spanish test are displayed in the histogram.
Which of the following best describes the shape of the data, and why?
A. The data is symmetric because the average test grade falls in the middle of the data.
B. The data is not symmetric because the grades are spread out in each of the intervals.
C. The data is skewed because there is a large amount of data, showing the average grade in the middle.
D. The data is bimodal because there is a low amount of data in the first and last intervals, showing that many students had low grades.
Answer:
C) The data is skewed because there is a large amount of data, showing the average grade in the middle.

Sarah wants to make a quilt that is 6 feet wide and 8 feet long. She is patching together 4-inch-sided squares of fabric to make the quilt. How many patches of fabric will Sarah need?
Answer:
Step-by-step explanation:
Sarah will need 482 patches of fabric
Answer:
x = 36
Step-by-step explanation:
First calculate the area of both quilts.
First Quilt area: LxW
So, 6 x 8 = 48 48 ft^2
= Square Quilt Area: S^2
= 4 × 4 = 16 inches^2
= 16 square inches = 1.333 ft
= 1.333 ft = 48
Answer: x = 36
Sara would need 36 patches of fabric.

The diameter of a child's bicycle wheel is 14 inches. Approximately how many revolutions of the wheel will it take to travel 2,400 meters? Use 3.14 for π and round to the nearest whole number. (1 meter ≈ 39.3701 inches)
4,298 revolutions
2,149 revolutions
1,340 revolutions
171 revolutions
Answer:
2,149 revolutions
Step-by-step explanation:
First we need to find circumference of the circle (the bicycle)
C = 2πr (radius is half the diameter)
C = 2 x 3.14 x 7
C = 43.96in.
Then convert meters to inches
2,400 meters = 94,488 inches
Lastly, divide the inches by the circumference of the circle
94,488 ÷ 43.96in.
= 2,149.40
So it is an estimate of 2,149 revolutions

Ken’s seventh grade class plans to collect empty aluminum pop cans as a fund raiser to
buy two new books for the school library. The books will cost a total of $50.
a.) The number of pounds of empty cans needed by the class is 200 pounds.
b.) The number of empty cans needed by the class to collect are 5486 cans.
The books will cost a total amount of $ 50.
If $ 0.25 per pound is the current price for aluminium at the recycling centre, the number of pounds the class will have to collect is found by dividing the total amount needed by cost per pound is,
⇒ 50/0.25 = 200
b.) Six empty cans weigh 3.5 ounces.
1 pound = 16 ounces
200 pounds = 200 × 16 = 3200 number of ounces
3200/3.5 = 914.29
914.29 × 6 = 5485.7 cans ≈ 5486 cans
