For a science experiment, Claudia observes the effects of temperature on a substance. The original temperature is 9°C, and Claudia increases the temperature by 2°C each hour. Then Claudia graphs the relationship between time and temperature. What is the y-intercept of Claudia’s graph and what does it represent?

The drop in temperature is 42-(-54)=42+54=96℉. Rate of drop is 12℉. So it will take 96/12=8 hours.

Another way: -54-42=-96, -96/-12=8 hours.

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.
