Answer: 64%
Step-by-step explanation:
The band needs $800 for new uniforms and of that, they only raised $512.
Set up a proportion 
and plug everything you know in.
= 
Solve for x by cross multiplying and dividing.
512 × 100 = 51200
51200 ÷ 800 = 64
x = 64
The school band has raised 64% of their goal already.
Answer:
x=3
Step-by-step explanation:
First, combine like terms on the left side
4x-5x+9=5x-9
-x+9=5x-9
Subtract 9 on both sides
-x=5x-18
Subtract 5x on both sides
-6x= -18
Divide by -6 on both sides
x=3
Hope this helps! :)
U didn't mess up....
V = pi * r^2 * h....divide both sides by (pi)r^2
V / (pi)r^2 = h
