Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 17 pennies, 12 dimes, and 26 quarters. The rest of the coins are nickels. There are 66 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
_____ of the coins are not nickels.
Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11

Jeremy wants to verify that the transformation shown is a dilation. He finds the lengths of segments QA and AD to be 4 units.
Point Q is the center of dilation. Triangle A B C is dilated to create triangle D E F. The length of Q A is 4 and the length of A D is 4.
To verify that the transformation is a dilation, Jeremy should also check which of the following? Select three options.
QB = One-halfQE
QC = CF
DE = 2AB
AC = One-halfEF
if BC = 2.25, then EF = 2.25
Answer:
1,2,3
Step-by-step explanation:
Based on the information given regarding the triangle, to verify that the transformation is a dilation, the things that should be checked include:
QB = One-halfQEQC = CFDE = 2ABSolving the traingle.
From the information given, it was stated that Jeremy wants to verify that the transformation shown is a dilation and that he finds the lengths of segments QA and AD to be 4 units.
Therefore, to verify that the transformation is a dilation, Jeremy should also check QB = One-halfQE; QC = CF; and DE = 2AB.

y = 6/5x -5
Step-by-step explanation:
Points are (5,1) (0,-5)
-5 - 1/ 0-5 = 6/5 slope
y-y1= m(x-x1)
y- 1 = 6/5(x-5)
y -1 = 6/5X - 6
y = 6/5X -5
There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for a film cost £7.50. The sale of the tickets that night made was £2587.50

Step-by-step explanation:
Here is the full question
There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold
Total number of seats = 17 x 22 = 374
Number of tickets sold = £2587.50 / £7.50 = 345
So 345 people filled 345 seats
Unoccupied seats = 374 - 345 = 29

Answer:
21 square feet
Step-by-step explanation:
To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.
Version 1: 6 * 2 rectangle and 3 * 3 square
(6 * 2) + (3 * 3)
12 + 9
21 sq. ft.
Version 2: 5 * 3 rectangle + 2 * 3 rectangle
(5 * 3) + (2 * 3)
You could really just do 7 * 3 here.
7 * 3
21 sq. ft.
Either way, you still get 21 square feet as your answer.
