Lisa collected leaves from different trees for a science project. every day for a week (7 days), she collected 7 leaves. how many leaves did she collect by the end of the week? 14

49 leaves

Step-by-step explanation:

Given: Lisa collected 7 leaves each day and everyday for a week (7 days).

To find: The number of leaves collected by the end of the week.

Solution:

Total number of leaves collected in a day is 7.

Since there are 7 days in a week.

The leaves are collected for 7 days.

So, in order to find the total number of leaves collected we need to multiply 7 by 7.

the number of leaves collected by the end of the week

Therefore, she collected 49 leaves by the end of the week.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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.
