There are 4 quarts in one gallon.
Divide 65 quarts by 4 to see how many gallons this is equivalent to.
65/4 = 16.25
65 quarts = 16.25 gallons, so 32 gallons would be more than 65 quarts.
<u>32 gal > 65 quarts</u>
is your answer.
Option B: The area of the trapezoid is 157.5 m²
Explanation:
We need to determine the area of the trapezoid.
The area of the trapezoid can be determined by the formula,

where h is the height, a and b are the base of the trapezoid.
From the figure, it is obvious that
,
and 
Substituting these values in the formula, we have,

Simplifying the terms, we have,

Multiplying the terms in the numerator, we have,

Dividing, we get,

Thus, the area of the trapezoid is 157.5 m²
Hence, Option B is the correct answer.
Assuming that

That means that since a

value is the test score (because that's what the y-axis is labeled), your predicted test score is a
64.
