Santos flipped a coin 300 times. the coin landed heads up 175 times. find the ratio of heads to total number of coin flips. express as a simplified ratio.

7:12 is the right answer.

Step-by-step explanation:

Number of times Santos flipped the coin = 300

Number of times the coin landed heads up = 175

We have to find the ratio of heads to total number of coin flips, this means 175:300.

Simplifying this we get,

Divide both the numbers by 5, we get 35:60

Again divide both the numbers by 5, we get 7:12

Now, this cannot be simplified further as it does not have a common factor. So, 7:12 is the right 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
