The tiles that bruce used were each of a square foot in the area. the table shows the area covered by felicia’s tiles in terms of the number of tiles used. number of tiles area covered (sq. ft.)9                             118                           227                         3 bruce and felicia want to know whose tiles cover the most area per tile. write an equation representing the area felicia covered, y, in terms of the number of tiles she used, x.

Step-by-step explanation:

We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.

Let x= Number of tiles

y=Area  covered by  Felicia's tile

The ratio of x and y remains constant.Therefore, it is direct proportion .

Equation of direction proportion is given by

Where

k=The value of ratio of x and y

x and y are variables

We have k=9

Substitute the values in the equation

Then, we get

This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.

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

78.59 is the mean
