The volume of a rectangular pyramid

Given a rectangular pyramid of width W, length L, and Height H, the volume is

V=\frac{\text{WLH}}{3}

We have to assume the pyramid given in the question has a square shape of length and width of L=34.5 feet and W = 34.5 feet, and a height of H=55 feet, thus the volume is:

V=\frac{\text{34.5}\cdot34.5\cdot55}{3}=21,821.25ft^3

Correct choice: A

Given f(x) = x3 – 2x2 – x + 2, <br><br> the roots of f(x)
anyanavicka [17]

f(x) = x³ – 2x² – x + 2

 

 0 = x3 – 2x2 – x + 2

 (x-2)(x-1)(x+1)=0

 x1=-1

 x2=1

 x3=2

Which ratio is incorrectly written in Olivia's conversion?
klasskru [66]

Answer:

Choice 3

Step-by-step explanation:

The third fraction (third refers to the answer number) is incorrect. As written, the cups won't cancel. The correct way to do this is to invert the fraction.

4 tablespoons

===========

1/4 cup

This is an extremely important procedure to know. Make sure you understand what the basis of it is. Often  times in higher physics, you don't have a proper relationships and this method (called dimensional analysis) is the only tool you have to work with.

So each term has at least 1 cancelation that occurs with the prior term. And it is the units that you look to cancel, and that determines which way to put the intermediate steps.
