Answer:
17
Step-by-step explanation:
The computation of the number of elements are in (A ∩ B) is shown below;
Given that
Set A contains 35 elements
And, set B contains 22 elements
Now if there are 40 elements in (A ∪ B)
So, the number of elements are in (A ∩ B) is
= 35 + 22 - 40
= 17
Surface area of small sphere = 1441cm^2
Surface area of bigger sphere = 2567cm^2
Surface area of largest sphere = 1441 + 2567
= 4008cm²

Kelby drank 168 glasses of water per week
i.e 24 glasses per day
Since 8 eight-ounce glass of water is for every 50 pounds.
1 eight-ounce glass is for = 50/8 pounds
and 24 glasses of water is for = 50*24/8
= 150pounds
So kelby probably weighs 150 pounds
