What is the center of the circle that has a diameter whose endpoints are (9, 7) and (-3, -5)?

(3, 1)

Step-by-step explanation:

Midpoint of the diameter is the center

Since endpoints are (9, 7) and (-3, -5)

Midpoint will be:

So the center is (3, 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
