The Thompson family is buying a car that can travel 70 miles on two gallons of gas. Assume that the distance traveled in miles y
varies directly with the amount of gas used x. This can be represented by y=35x. Graph the equation on the coordinate plane. How many miles does the car per gallon of gas?

<u>Volume Of A Regular Solid</u>
When a solid has a constant cross-section, the volume can be found by multiplying the area of the base by the height. The area of a trapezium is
where and
are the lengths of the parallel sides and h the distance between them.
The figure shows a solid with a trapezoid as the constant cross-section and a height x. The volume of the solid is
The image doesn't explicitly say if the length of 4.5 is the height of the trapezium or the length of that side. We'll assume the first, so our data is:
We now compute the volume
