Please help 6th grade math im new to it pleaae explain good​

0.6

Step-by-step explanation:

Given the trapezoid formula:

1/2(b1+b2/2)xH

We are given the numbers for the trapezoid:

0.3,0.9,1

To solve this here is what we are going to do.

1/2(0.9+0.3)x1

So add 0.9+0.3=1.2

Then Divide 1.2/2=0.6

So multiply 0.6 x 1=0.6

0.6 is your answer

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

f(x) = y

f(-3) = -5
