Jack is designing a t-shirt for his geometry class. the front reads: the polygon in which one angle is 68 degrees and each additional angle increases by 20 degrees. what is the only possible answer for the back?
triangle
quadrilateral
pentagon
hexagon

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
