the ship left port x at 22 45 on friday and arrived at port y at 7 1/4 hours later. at what time and day did the ship arrive at port y?

The ship arrived at 5 am on Saturday

Step-by-step explanation:

Here, we want to know at what time and day the ship arrive the second port

we simply need to add the time it left the first port and the amount of time the journey took

Mathematically, that will be;

22:45 + 7 1/4

1/4 is same as 60/4 = 15 minutes

So we have;

22:45 + 7:15

= 5 am on Saturday

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.
