Answer:

Surface Area = 82.8 square meters

Volume = 37.96 cubic meters

Surface area:

6 × 2 = 12

9 × 2 = 18

8.8 × 6 = 52.8

12 + 18 + 52.8 = 82.8

Volume:

6 × 2 × 9.49 = 113.88

113.88 ÷ 37.96

Please please help. I have a bunch of these and I don’t understand it at all
shtirl [24]
The correct option is: Option (B) \sum_{i=1}^{7} (5i-2)

Explanation:

First thing is that the difference between each number in the series with the next number is 5. It means it must be the multiple of 5. There are two options that contain multiples of 5: Option B and Option D. Now in the option D, the upper limit is 6. If we put 6 in the expression: 5(6)-2, the last term would be 28. However in the series given in the question, the last term is 33. Hence 5(7) - 2 = 35 - 2 = 33 which is Option B.

When i=1: 5(1)-2 = 3
When i=2: 5(2)-2 = 8
When i=3: 5(3)-2 = 13
.
.
When i=7: 5(7)-2 = 35-2 = 33
Hence the correct option is (B).

How to do question 4?
Nutka1998 [239]
Marie states that any integer greater than 4 will always get an even number of factors.

This can be proven wrong by (for example) 12.

12 has these factors:

1 x 12
2 x 6
3 x 4

12 has an ODD number of factor pairs.

Another example is 28.

28:
1 x 28
2 x 14
4 x 7

28 has an odd number of factor pairs.

I hope this helps!
