State whether the lines are parallel, perpendicular, coinciding, or neither y=0.3x+40 and y=-3 1/3x+15

Perpendicular

Step-by-step explanation:

The slope of the first equation is 0.3 = 3/10

You need the opposite sign of the reciprocal for perpendicular

10/3 is reciprocal, 3 1/3 is equivalent, - 3 1/3 is perpendicular

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
