Question

You are installing a pipe that is 6 2/3 feet long. How long is it in inches

Answer 1

You are installing a pipe that is 6 2/3 feet long. How long is it in inches

Remember that

1 ft=12 in

so

6 2/3 ft=(6 2/3)*12

Convert mixed number to an improper fraction first

`6(2)/(3)=6+(2)/(3)=(20)/(3)`

substitute

`(20)/(3)\cdot12=80\text{ inches}`

therefore

the answer is 80 inches

Part 2

You have a pallet of building materials that weighs a total 9,500 lbs. The materials are organized in three bundles. The first one weights 2,243 lbs., and the second weighs 3,431 lbs. What is the weight of the third bundle?

Let

x ------> the weight of the third bundle

we know that

9,500=2,243+3,431+x

solve for x

9,500=5,674+x

x=9,500-5,674

x=3,826 lbs

therefore

the answer is

The weight of the third bundle is 3,826 lb

Part 3

You are painting a wall that is 11 feet high and 25 feet long. What is the total surface area to be painted

To find out the surface area multiply the high by the length of the wall

so

(11)*(25)=275 ft2

the answer is 275 square feet
