1. A set of steps leads down into a swimming pool. Some of the steps are above the water level and some of the steps are below the water level. The top of one of the steps is even with the water level of the pool. Each step is 8 inches tall. Positions below the water level are represented as negative values and positions above the water level are represented as positive values. Madison's feet are on the step that is even with the water level of the pool. Madison steps 1 step down. (a) What numeric value represents the position of Madison's feet now? (b) What is the additive inverse of "Madison steps 1 step down?" Describe the additive inverse in terms of the situation. Explain how you know this is the additive inverse.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.

um is there supposed to be a picture?
