Answer:
9.48 mm
Step-by-step explanation:
C=59.59 mm
59.59=2*3.14*r
r=9.48 mm
First, let's multiply 86.50 by 20 since she deposited $86.50 each month for 20 months.
86.50 * 20 = $1,730
Now, we have to divide this by 24.50 * 20 to find how much out of her $1,730 that she used on singing lessons.
24.50 * 20 = $490
Subtract how much she used for singing lessons from her total amount.
1,730 - 490 = $1,240
Finally, we multiply the amount she has left by 1/4 to find out how much she spent on her summer camp. We can also do this by multiplying 1,240 by 0.25 since 0.25 = 1/4.
1,240 * 0.25 = $310
So, Molly spent $310.00 on her summer camp.
Hope this helped!

Answer:
Step-by-step explanation:
To get from the top square to the bottom square, multiply by - 3 So the middle position of the bottom square is - 30. If you solve all of the top square, you can get the bottom square easily enough.
The diagonal of the top square adds to 13 + 10 + 7 = 30
The top line of the top square must add to 30 as well 13 + 11 + 6. Put 6 in the middle position.
The right hand vertical line must add to 30. 11 + 7 + 12 = 30
The middle row must add to 30. 10 + 12 + 8. 8 goes in the left position of the middle row.
Let's summarize what we have so far.
13 6 11
8 10 12
7
We can fill in the last two spaces by adding to 30
13 6 11
8 10 12
9 14 7
That completes the top magic square.
To get the bottom magic square, multiply by -3
- 39 - 18 -33
-24 -30 -36
-27 -42 -21
