F(x) = 2x g(x) = 50x
Find (f. g)(x). Assume x2 0.
A. (f. g)(x) = 50x
B. (f. g)(x) = 10/2
c. (f. g)(x) = 52c
D. (f. g)(x) = 10x

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

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

they would have to work 32 hours.
