Considering the volume of a cylinder, we have that:
The volume of a cylinder of radius r and height h is given as follows:
Considering that the radius is half the diameter, and that each inch has 0.0833 feet, the parameters in feet for this problem are given as follows:
r = 0.25, h = 5280.
Hence the volume in cubic feet is:
V = 3.14 x (0.25)² x 5280 = 1036.2 feet³.
The number of barrels in this pipeline, considering the volume of a single barrel, is given as follows:
1036.2/5.61 = 185 barrels.
The worth of 1 mile of oil, considering the price of $100 per barrel, is given by:
185 x 100 = $18,500.
One mile of oil is worth $18,500.

First, notice that we want the average to be 85 or higher. We can write this like this:
where mu is the average.
We know that there are four tests, and there are already three grades: 78,80 and 88. Then if we calculate the mean we have:
but we already know that the average must be greater or equal than 85, then, combining both expressions we get the following:
solving the inequality for x, we get:
therefore, Erika needs a score of 94 or higher in order to make the honor roll
Check the picture below.
the volume of the prism will simply be the product of the triangular area and its length, it has a length of 8, thus
