The perimeter of a rectangle is 154 cm. The ratio of the length to the width is 10: 1. Find the length and the width

length=70cm

width=7cm

Step-by-step explanation:

total ratio=10 + 1

=11

length(2)=10/11 x 154 cm

=10 x 14cm

=140cm

one length is 140 cm/2=70cm

width(2)=1/11 x 154cm

=14cm

one width is 14cm/2=7cm

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
