Question 1)
The answer is B because all the points correlate.
Question 2)
Your numbers are:
2,2,4,5,6,7,8, and 9.

Since it says "1 decimal place" the answer is 5.4
Question 3)
Your numbers are:
1,2,3,3,4,5,7, and 8.
Start crossing them out.
1-2-3-3-4-5-7-8
2-3-3-4-5-7
3-3-4-5
3-4
Since your left with 2 numbers, you go in between.
3.5
120,000×0.016=1,920
(1,920+8,962.49)÷120,000)*100=9%
(8,962.49÷120,000)*100=7%
I am assuming this is for a circle??
Area for circle is pi*r^2
you didn't say what to use for pi so I will use 3.14
so area = 3.14 * 6^2
6^2 = 36
so 3.14*36 = 113.04 square feet. Round this answer off as needed.
