If the volume of the pyramid shown is 360 inches cubed, what is its height?

A rectangular pyramid with base of 12 inches by 10 inches and a height of h.
1 in.
3 in.
6 in.
9 in.

9 inches

Step-by-step explanation:

The formula for the volume of a rectangular pyramid is

We need to manipulate the volume equation to solve for the height (H)

Now we can plug in the given values:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
