The first thing we must do for this case is to define variables.
We have then:
x = number of dimes
y = number of half-dollars
We write the system of equations:
x + y = 36
0.10x + 0.50y = 12
Solving the system we have:
x = 15
y = 21
Answer:
He has 15 dimes

We have an eight of a circle has area 9π sq in, so the total circle has area
πr² = 8(9π) = 72π
r² = 72 = 2(36)
r = 6√2 ≈ 8.485281374238571
Answer: A. 8.48 inches
Answer:
28%
Step-by-step explanation:
total percent is 100%
we could rewrite the equation as:
48% + 24% + f = 100%
72% + f = 100%(subtract 72 on both side)
f = 28%
