The graph shows gas mileage for a car. What is the unit rate?
A)
54
miles per gallon
B)
miles per gallon
27
09
27 miles per gallon
D)
54 miles per gallon

The unit rate = 27 miles per gallon.

Hence, option C is true.

Step-by-step explanation:

From the given line graph:

Taking two points

The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)

Refine

Therefore, the unit rate = 27 miles per gallon.

Hence, option C is true.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
