My four factors add up to 48, and i am between the numbers 30 and 40. what number am i?

Your factor adds up to 48. That means you can’t be a prime number, so starting from 39 and adding all of the factors: 39 + 13 + 3 + 1 = 56, 35 + 7 + 5 + 1 = 48. You are 35.

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
