Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

\large{ \frac{ {x}^{2} }{ {5}^{2} }  =  {4}^{2} }

First, we simplify 5² and 4²

\large{ \frac{ {x}^{2} }{25}  = 16}

Multiply the whole equation by 25 to get rid of the denominator.

\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\  \large{ {x}^{2}  = 400}

Square both sides and solve the equation.

\large{ \sqrt{ {x}^{2} }  =  \pm{ \sqrt{400} }}

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

\large{x = \pm{20}}

Tatiana [17]

It will take 764664.6875 days to empty the water

<h3>How to determine the time to empty?</h3>

The given parameters are:

  • Volume = 1 cubic mile
  • Rate = 1000 gallons per minutes

The time is calculated as:

Time = Volume/Rate

So, we have:

Time = 1 cubic mile ÷ 1000 gallons per minute

Convert gallons to cubic mile

Time = 1 cubic mile ÷ (9.0817e-13 * 1000) cubic mile per minute

Divide

Time = 1.10111715 × 10^9 minute

Convert to days

Time = 764664.6875 days

Hence, it will take 764664.6875 days to empty the water
