Aclassroom has a length of 30 ft. and a width of 20 ft. the flooring is to be replaced by tiles. if each tile has a length of 36 in. and a width of 24 in., how many tiles are needed to cover the classroom floor?

100

Step-by-step explanation:

Hello! to calculate the number of tiles needed for the floor you need two things

1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile

Width=20ft=240in

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.

leght=30ft=360in

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.

N=10X10=100

no he doesnt because "-16' is negatiive

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
