The principal of a school asked all 7th grade students, "Would you prefer to add pizza or hamburgers to the lunch menu?" Everyone surveyed had to choose one of the two choices. The survey showed that 38% prefer to add hamburgers. Choose all of the statements that are valid conclusions based on the data.

A - all of the students at the school prefer pizza to hamburgers

B. 62% of the 7th grade students at the school prefer to add pizza

c. 38% of all of the students at the school prefer to add hamburgers

D. all of the 7th grade students at the school like pizza and hamburgers
0.38% of the 7th grade students at the school prefer to add hamburgers

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

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

faster, im not sure why but i know it is faster
