In a trapezoid with bases of lengths a and b, a line parallel to the bases is drawn through the intersection point of the diagonals. find the length of the segment that is cut from that line by the legs of the trapezoid.

if we name that part x, then we can say

1/x = 1/a + 1/b

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
