The perimeter of a rectangular fence is to be at least 144 feet and no more than 216 feet. If the length of the fence is to be three times the width, what is the range of values for the width of the fence? __ ft ≤ width ≤ __ ft

let width be x

then length= 3x

in first case

2(x+3x)= 144

8x=144

x=18

again

2(x+3x)= 216

8x= 216

x=27

the range for width is

18≤ width ≤27

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

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
