Given

Length (L)=18 in.

width (B)=12 in.

height(h)=4 in.

Volume of water is increasing at a rate of 569 in^3/s

Volume of a box is given by=LBh

and \dot{V}=LB\dot{h}

as L&B are constant therefore

How do you solve this problem<br> (2x+8)2=64
asambeis [7]

Answer:

12

Step-by-step explanation:

If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;

How do you convert degrees to percents
denpristay [2]

Answer:

Step-by-step explanation:

A circle has 360 degrees, so if you want to express an angle in terms of a percentage, just divide the angle measurement (in degrees) by 360 and multiply by 100. In reverse, divide the percentage by 100 and multiply by 360.
