6. Solve for x. Show all work and round to the nearest hundredth if necessary.
20
55°

x ≈ 11.47

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos55° = = ( multiply both sides by 20 )

20 × cos55° = x , then

x ≈ 11.47 ( to the nearest hundredth )

correct

step-by-step explanation:

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
