Answer:
Step-by-step explanation:
We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.
The volume for a cone is given by:
Where r is the radius and h is the height.
Since the diameter is 14, the radius is 7.
And we are given that the height is 15.
Therefore, the volume will be:
Use a calculator:
The volume of the cone is approximately 769.7 cubic inches.
x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3
<h3>Your answer is 3.</h3>
Answer:
Step-by-step explanation:
-6n + 2.9 = 11
subtract 2.9 from both sides
-6n = 8.1
divide both sides by -6
n = -1.35
2/3n - 3 = 8
add 3 to both sides
2/3n = 11
multiply both sides by 3
2n = 33
divide both sides by 2
n = 16.5

There would be 60 pages in the book totally because you would set 40/x=2/3 and solve for x.
40/x=2/3
2x=120
x=60
