Jen uses 8.6 gallons of gasoline to drive 164.7 miles. Which is the best estimate for the number of miles per gallon of gasoline her vehicle gets?

19.15 miles/gallon

Step-by-step explanation:

Gasoline used = 8.6 gallons

Distance driven = 164.7 miles

Number of miles per gallon = Distance driven / Gasoline used

= 164.7 miles / 8.6 gallons

= 19.151162790697 miles/gallon

Approximately 19.15 miles/gallon

Number of miles per gallon of gasoline her vehicle gets is 19.15 miles/gallon

i am sure it will be 90 degrees.

step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
