Answer:
9 percent of 578 is 52.02.
Step-by-step explanation:
578/x=100/9
(578/x)*x=(100/9)*x - we multiply both sides of the equation by x
578=11.111111111111*x - we divide both sides of the equation by (11.111111111111) to get x
578/11.111111111111=x
52.02=x
x=52.02
volume of a cylinder = V = πr²h, r = radius and h = height.
if r = 3 and h = 4, then V = π3²(4) => V = 36π => V ≈ 113.1.
Let the width be 2w. Then the lenght is 5w. So:
(2w)(5w)=490
10w²=490
w²=49
w=±7
So, 2w=width=14 in; and 5w=length=35 in

Answer:
x = -15/2
Step-by-step explanation:
For this problem, we will simply use equation properties to solve for x.
2x - 5 = -20
2x - 5 + 5 = -20 + 5
2x = -15 ( Add positive 5 to both sides )
2x * (1/2) = -15 * (1/2)
x = -15/2 ( Multiply both sides by 1/2)
Hence, the solution to x is -15 / 2.
Cheers.
