Which geometric object is defined as the set of ballpoints in a plane at a given distance a. parabole b. line segment c. line d. circle

Check the picture below.

notice, all points are equidistant from the center of it, wherever the center happens to be.

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
