The equation to this would be $0.50m+$30.00=130 because each mile is $0.50 and m would represent as how many miles it well and then adding $30.00 because it’s the flat rate.
The formula for volume of a pyramid is V = 1/3 bh. If we plug everything into the formula, you should get an answer of 17cm cubed. Hope this helps!
Using the cosine function:
Solve for b:
