Answer:

x=13

Step-by-step explanation:

By the definition of an angle bisector, we have that 8x-23=5x+16.

We can add 23 to both sides to get 8x=5x+39.

We can then subtract 5x from both sides to get 3x=39.

We can finally divide both sides by 3 to get \boxed{x=13}

A certain cylindrical tank holds 20,000 gallons of water which can be drained from the bottom of the tank in 20 minutes the volu
zalisa [80]
Given that the volume of water remaining in the tank after t minutes is given by the function

V(t)=20,000\left(1- \frac{t}{20} \right)^2

where V is in gallons, 0 ≤ t ≤ 20 is in minutes, and t = 0 represents the instant the tank starts draining.

The rate at which water is draining four and a half minutes after it begins is given by

\left.
 \frac{dV}{dt} \right|_{t=4 \frac{1}{2} = \frac{9}{2} 
}=\left[40,000\left(1- \frac{t}{20} \right)\left(- \frac{1}{20} 
\right)\right]_{t= \frac{9}{2} } \\  \\ =\left[-2,000\left(1- 
\frac{t}{20} \right)\right]_{t= \frac{9}{2} }=-2,000\left(1- 
\frac{4.5}{20} \right) \\  \\ =-2,000(1-0.225)=-2,000(0.775)=-1,550\, 
gallons\ per\ minute

Therefore, the water is draining at a rate of 1,550 gallons per minute four ans a half minutes after it begins.

Answer option E is the correct answer.
