Write a real problem you could answer by solving the equation -8x+60=28

tankabanditka [31]

Bob found out that he can dig 8 inches down every minute. If he wants to put a 5 foot stick in the hole with 28 inches showing, how long does he have to dig?

(so to solve you convert 5 feet to 60 inches then do the equation -8x+60=28 then you add 8x to both sides, subtract 28 then divide by 8 leaving you with 4 minutes)

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Anettt [7]

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

$V=\pi r^2h$

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:

$6000=(3.141592654)(r^2)(40)$

Simplify on the right to get

$6000=125.6637061r^2$

Divide both sides by 125.6637061 to get that

$r^2=47.74648294$

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
