N = number of sides in the shape.

The formula I know it from is; n - 2 x 180

For example; 7 - 2 [5] x 180 = 900

So, a heptagon's interior angles should add up to 900.

A vet bill for your dog is $145. The bill includes $23 per vaccination shot and a $53 office fee. How many shots did your pet re

Subtract $145-$53 and you will get 92.
Then divide 92 by 23 and you get 4.
The answer is 4 because when you subract 53 from 145 you are seeing how much you paid without the fee.

Zoe is making a quilt using 15 red squares and 30 green squares. Which combination shows the same ratio of red squares to green
Scilla [17]

Answer: A. 3 red squares to 6 green squares

Step-by-step explanation:

Method 1) Find a common factor between 15 and 30. For this problem, I'll pick 5. Divide both numbers by this common factor.

15/5=3 red squares

30/5=6 green squares

<em>3 red squares to 6 green squares</em>

Method 2) Find the greatest common factor between 15 and 30. The GCF is 15. Divide both numbers by the GCF.

15/15=1

30/15=2

This leaves you with a ratio of 1 red square to 2 green squares. 1:2 is equivalent to 3:6

<em>3 red squares to 6 green squares</em>
