The rainfall, r, is inversely proportional to the water shortage, s, in a city. if the rainfall in the city is 40 inches, there is a water shortage of 200 million gallons per day. which statement best describes the inverse relation of the rainfall in terms of the water shortage? a. the equation can be used to tell that if the water shortage is 150 million gallons, then the rainfall in the city is approximately 53.33 inches. b. the equation can be used to tell that if the water shortage is 150 million gallons, then the rainfall in the city is approximately 33.33 inches. c. the equation can be used to tell that if the water shortage is 150 million gallons, then the rainfall in the city is approximately 33.33 inches. d. the equation can be used to tell that if the water shortage is 150 million gallons, then the rainfall in the city is approximately 53.33 inches.

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

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
