Lisa's family drove 830.76 miles to visit her grandparents. lisa calculated that they used 30.1 gallons of gas. how many miles per gallon did the car average?

27.6 miles per gallon

Step-by-step explanation:

Lisa's family drove 830.76 miles to visit her grandparents.

Lisa calculated that they used 30.1 gallons of gas.

To calculate the car average =

                                         =

                                         = 27.6 miles/gallon

The mileage of the car would be 27.6 miles/gallon.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
