Explain how the decimal point moves when you multiply 2.3 by 10

10 = 10^1

The exponent 1 is positive. The positive exponent means we move the decimal point to the right. Specifically we move to the right 1 spot.

2.3 turns into 23 after multiplying by 10^1

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

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
