Answer: $235,62
Step-by-step explanation:
You need to use the formula for calculate the volume of a cylinder:
Where "r" is the radius and "h" is the height.
You know that the cylindrical container has a diameter of 0.5 feet and a height of 5 feet (Remember that the radius if half the diameter):
Then, you need to substitute these values into to get the volume of the cylindrical container:
Since the gas costs $60 per cubic foot, you need to multiply the volume of the container by $60 to get the total value of the gas in the container if it's filled completely. Then:
29,140. 31000 times 6% = 1860.
The question is incomplete. Here is the complete question:
A machine covers 5/8 square foot in 1/4 hour. what is the unit rate?
Answer:
2.5 square feet per hour
Step-by-step explanation:
Given:
Area covered by a machine =
Time taken to cover the given area =
Now, unit rate of the first quantity with respect to second quantity is the magnitude of the first quantity being when the second quantity is one unit.
Here, the first quantity is the area covered and the second quantity is the time taken.
So, unit rate is the area covered by the machine in 1 hour.
In order to find that, we use the unitary method and divide the area by the total time taken. Therefore,
Thus, the unit rate is 2.5 square feet per hour.
You plug in a 3 wherever you see an x
2x^3-4x^2+6x
2(3)^3-3(3)^2+6(3)
2(27)-3(9)+18
54-27+18
27+18
=45
