4. There are two water tanks. Tank A and Tank B. At the onset of the situation, Tank A is empty and begins to be filled at a rate of 2 gallons per minute. At the same time, Tank Bhas in it, 140 gallons, and begins to be drained at a rate of 5 gallons per minute. Write a system of equations to model this situation, where x represents the minutes. Determine the number of minutes until the tanks have the same amount of water. How many gallons of water do each of the tanks have? ​

69

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
