If a diameter of a cylinder is 5 yd and the height is 8 yd what is the volume?

Answers

Answer 1

Answer:

Answer:

$\large\boxed{V=50\pi\ yd^3\approx157\ yd^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the diameter d = 2r = 5yd → r = 2.5yd and the height H = 8yd.

Substitute:

$V=\pi(2.5)^2(8)=\pi(6.25)(8)=50\pi\ yd^3\n\n\pi\approx3.14\to V\approx(50)(3.14)=157\ yd^3$

You are going to mix a gallon bucket of window cleaner. The instructions direct you to mix 1 part cleaner to 3 parts water. How much cleaning solution will you need to use?* 1 ½ quarts 1 pint 2 quarts 1 quart

Answers

Answer:

Option D. 1 quart

Step-by-step explanation:

In a solution of 1 gallon we have to calculate the amount of cleaning solution will be needed.

Since mixture prepared will be in the ratio of 1 : 3 (cleaning solution : water)

So total amount of cleaning solution in 1 gallon = $(1)/(4)$ gallon

As we know 1 gallon = 4 quarts

so $(1)/(4)$ gallons = ( $(1)/(4)$ )(4) = 1 quart

Therefore, 1 quart of the cleaning solution will be added.

1 quart

Further explanation

Given:

You are going to mix a gallon bucket of the window cleaner.
The instructions direct you to mix 1 part cleaner to 3 parts water.

Question:

How much cleaning solution will you need to use?

1 ½ quarts
1 pint
2 quarts
1 quart

The Process:

From the text above, we will mix the window cleaning liquid in a gallon bucket by mixing 1 part cleaner to 3 parts water. In other words, the ratio of the mixture between the cleaning solution with water is 1 : 3.

The sum of the ratios is 1 + 3 = 4, meaning that in a gallon bucket there are four parts.

Furthermore, based on this ratio we can state the composition in solution as follows:

$\boxed{(1)/(4)}$ of a gallon bucket is a cleaning solution
$\boxed{(3)/(4)}$ of a gallon bucket is water

Remember that $\boxed{ \ 1 \ gallon = (1)/(4) \ quarts \ }$ .

Thus we need $\boxed{ \ (1)/(4) \ }$ of cleaning solution to mix a gallon bucket of window cleaner.

If x > y and y > z, then x > z. This describes which ordinal scale preference? A. Asymmetry B. Transitivity C. Negative transitivity D. None of the above

Answers

Answer:

Step-by-step explanation:

Final answer:

The given statement 'If x > y and y > z, then x > z' describes the concept of transitivity in ordinal scales.

Explanation:

The given statement 'If x > y and y > z, then x > z' describes the concept of transitivity in ordinal scales. Transitivity is the property that allows us to compare elements in a set based on their relationships with other elements. In this case, if x is greater than y and y is greater than z, then we can conclude that x is also greater than z.

A washer and a dryer cost $814 combined. the washer costs $36 less than the dryer. what is the cost of the dryer?

Answers

This is a systems of equation problem.
First, set up the equation.
814=w+d w=d-36

Second, insert w= in for w in the equation.
814=d-36+d

Third, combine like terms.
814=2d-36

Fourth, solve the equation by adding 36 and dividing by 2 to both sides.
814=2d-36
+36 +36
___________
850=2d
----- ----
2 2

__________
425=d

So the dryer (d) costs $425.
