Convert 290 into centimeters

290 what sir,

To change, first you need units

Okay

10mm = 1cm

290 mm =29 cm

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

if you need just tell me and i will come to the rescue.
