C=2πr and x^2+y^2=r^2
r=4 because of the equation (16)^1/2 is 4
C=8π
First we subtract it:
18 - 15 = 3
Now we divide it to the original:
3 / 15 = 0.2
Multiply by 100:
0.2 * 100 = 20%
Answer:
Let x be the price of an adult ticket and y be the price of a youth ticket.
One family spends $134 on 2 adult tickets and 3 youth tickets so we can write: 2x+3y=134
Another family spends $146 on 3 adult tickets and 2 youth tickets so we can write: 3x+2y=146
We need to find y so we eliminate x. Multiply (1) by 3 and (2) by 2 to obtain (3) and (4): 6x+9y=402
6x+4y=292
Subtract (3) and (4) and solve for y: 5y=110
y=22→$22

Answer:
G 328 ft
Step-by-step explanation:


AB = 229.431 ft
AB² + BC² = AC²
229.431² + h² = 400²
h = 327.659 ft ≈ 328 ft
