Answer:
Step-by-step explanation:
For this case we assume that the square have sides of length x.
So then the area for this square is given by
We have a rectangle and on this case we have this information :" the rectangle has side lengths 2 less and 2 more than a square"
So then the sides of the rectangle needs to have lengths a-2 and a+2, and if we find the area for the rectangle we got:
And as we can see th area for the rectangl is 4 units less than the area for the rectangle:
Answer:
Exact answer is 10.4ft ... approximation is 12ft
Step-by-step explanation:
The formula for volume of a sphere is as follows
Simply plug volume in and solve for r to get the radius
now simply multiply the radius by 2 to get the answer of 10.4ft
if you do the same calculation but switch 113.04 to 120 to do the approximation value you get 12ft
Total number of volunteer students for a committee = 7
Number of committee = 5
Number of ways of selecting the committee from the 7 volunteers = 7C5 = 7!/(5!*2!) = 21 ways.
There are 21 ways in which the 5-committee member can be selected from the 7 volunteers.
