X / 6 + 2 = 9
x/6 = 9 - 2
x/6 = 7
x = 7 * 6
x = 42 <== ur number
Using conversion of units and volume of a cylinder, it is found that 23.17 cubic yards of concrete are needed, option D.
The volume of a cylinder of radius r and height h is given by:

In this problem:
- We want the volume in cubic yards, thus, the units of radius and height have to be in yards.
- 32 inches in diameter, thus 16 inches of radius. Since each inch has 0.0278 yards, this is a radius of 0.44 yards, thus
. - Height of 8 feet, and since each feet has 0.33 yards, this is a height of 2.67 yards, thus

- 14 poles, thus the volume is multiplied by 14.
Then:

23.17 cubic yards of concrete are needed, option D.

Answer: A. There all 90 degrees
Step-by-step explanation:
Given: Three parallel lines are cut by a transversal and one angle is measured to be 90 degrees.
We know that if two lines cut by transversal the following pairs are equal:
- Vertically opposite angles.
- Corresponding angles.
- Alternate interior angles.
- Alternate exterior angles.
If one angles measures 90°, then its supplement would be 90°.
Then by using above properties , we will get measure of all angles as 90°.
Answer: Yes ,because it isn't the same the number since the number of digits aren't the same so you make it the same number of digits by putting 0 in the back so 1.7 turns to 1.700 to make it the same digits of 1.700.
Step-by-step explanation:
I’m pretty sure that the answer 783 :)
