If you divide these numbers instead of trying to simplify it equals the decimal 0.8.
If you move the decimal point two places to the right it's 80%.
Answer: -120
Step-by-step explanation:
this would be the answer because if you take a positive and add it to a negative you get zero if their the additive inverse of the number.
Answer:
63 in.3 that's what I got so I hope it's right
Answer:
d = 13.8 feet
Step-by-step explanation:
Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:

Simplify on the right to get

Divide both sides by 125.6637061 to get that

Taking the square root of both sides gives you
r = 6.90988299
But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8
