HELP ME!! I NEED HELP WITH A MATH QUESTION/ BRAIN TEASER!! PLEASE?

Question

A certain type of gutter comes in 6-foot, 8-foot, and 10-foot sections. How many different lengths can be formed using three sections of gutter?

Answer 1

6-6-6

6-6-8

6-8-8

6-8-10

6-10-10

6-6-10

8-8-8

8-8-10

8-10-10

10-10-10

10

Answer 2

dont know 6 8 10 maybe  

Answer 3

Since the difference between 6 and 8 is 2, and 8 and 10 is 2, you can just count off by 2s from the min to the max.

Min = 6 + 6 + 6 = 18

Max = 10 + 10 + 10 = 30

So 18, 20, 22, 24, 26, 28, and 30.

7 Different lengths can be formed.

Answer 4

7

Answer 5

List out the different ways to arrange the sections and note what the total length would be:

6,6,6 = 18

6,6,8 = 20

6,6,10 = 22

6,8,8 = 22

6,10,10 = 26

8,8,8 = 24

8,8,10 = 26

8,10,10 = 28

10,10,10 = 30

There are 9 different combinations.  But only 7 different total lengths.

Answer 6

the answer is 7

possibilities:

1. 6 foot

2. 8 foot

3. 10 foot

4. 6+10=16

5. 8+10= 18

6. 6+8= 14

7. 6+8+10=24

Answer 7

I won't give you the answer but I'll tell you how to solve it.  Start creating a grid of all the possible combinations and add up the lengths.  I'll get ya started 6,8,10= 24 / 6,6,6 =18 / 8,8,8 = 24 ... etc.  Be careful not to include duplicate lengths in your final tally.  Good Luck.

Answer 8

666=18

888=24

101010=30

668=20

8810=26

6810=24

688=22

81010=28      ......................I believe 7 because some lengths added together make the same length.

Answer 9

i think 6,8,10,16,18,14,24
