Each of the triangular faces has an area of 32 m2.
What is the surface area of the square pyramid?

128 if you don't count the square base

Step-by-step explanation:

because each side has an area of 32, there are 4 triangular sides in a square pyramid, therefore 4*32 = 128

I couldn't find the area of the base because there were no side lengths given.

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

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.
