PLEASE HELP!! A tree broke during a storm. The part left standing was 10m, and the top of the tree landed 24 m from the base of the tree. How tall was the original tree?

A) Let c=20, b=12 and use the equation 202+122=a2

B) Let c=20, b=12 and use the equation 202−122=a2

C) Let c=12, b=20 and use the equation 122+202=a2

D) Let c=12, b=20 and use the equation 122−202=a2

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
