75% of 72 hours find the quantity represented by each percent

Answers

Answer 1

Answer: 54 is 75%
You set up a proportion
75/100=x/72
Mulitply 75×72 = 5400
Then divide it by 100=54
Therefore, 54 is 75% of 72

Answer 2

Answer: To solve this all you need to do is multiply 0.75 and 72 and you get 54.

A bakery sends 4 carton of rolls . Each carton contains 6 box's holding 12 rolls each. The store divides the rolls into 8 in each bag. How many bags of rolls are there?

Answers

4 times 6 to find out how many boxes there are.
There are 24, so you multiply this by 12 to find out how many rolls there are. There are 288 rolls.
Divide this by 8 to find how many bags there are. There are 36 bags.

start by finding how many rolls are in each carton: 6 X12= 72
now that you know how many rolls are in each carton, find the total amount of rolls in 4 cartons, simply by 72 X 4 = 288
now that there is 288 rolls total, just divide by 8 to find your answer: 36

0.6 is 10 times as much as what

Answers

To start, divide 0.6 by 10.
0.6/10
Now look at it, sentence should be 0.6 is 10 times as much as 0.06
To check just simply do 0.06 * 10 = 0.6
and it is correct.

0.6 / 10 = 0.06 and that is your answer.

S=2πr^2+2πrh
Solve for h

Answers

h = [S / (2πr)] - r

Further explanation

It is a case about two-variable linear equations and we have to solve the equation to get the variable h.

Our main plan is to isolate the variable h alone at the end of the process on one side of the equation until the variable will be equal to the value on the opposite side.

$\boxed{S = 2 \pi r^2 + 2 \pi rh}$

We can set it to be like this, i.e., just swapping positions on both sides but not changing the signs.

$\boxed{2 \pi r^2 + 2 \pi rh = S}$

We subtract both sides with $\boxed{2 \pi r^2}$ .

$\boxed{2 \pi r^2 + 2 \pi rh - 2 \pi r^2 = S - 2 \pi r^2}$

$\boxed{2 \pi rh = S - 2 \pi r^2}$

We divide both sides with $\boxed{2 \pi r}$

$\boxed{(2 \pi rh)/(2 \pi r) = (S - 2 \pi r^2)/(2 \pi r)}$

$\boxed{h = (S)/(2 \pi r) - (2 \pi r^2)/(2 \pi r)}$

We get the results as follows: $\boxed{\boxed{h= (S)/(2 \pi r) - r}}$

- - - - - - -

Let's check again from the beginning.

For example, r = 2 and h = 3, then we first calculate the value of S by using the initial equation.

$\boxed{S=2 \pi (2)^2 + 2 \pi (2)(3)}$

$\boxed{S = 8 \pi + 12 \pi }$

$\boxed{\boxed{S= 20 \pi}}$

Then, we substitute the results of S (with r = 2) into the new equation that we have compiled with h as the subject.

$\boxed{h =(20 \pi)/(2 \pi (2)) - 2}$

$\boxed{h = 5 - 2}$

We get the value h = 3 and it means that the equation has been proven.

Notes:

The formula that we discussed above is a formula for calculating the surface area of a closed cylinder.

$\boxed{S = 2 \pi r^2 + 2 \pi rh}$

Keywords: S=2πr^2+2πrh, solve for h, subtract, divide, subject, to isolate the variable h alone, two-variable linear equations

Final answer:

To solve for 'h' in the equation S = 2πr^2 + 2πrh, subtract 2πr^2 from both sides, divide by 2πr, simplifying the right side of the equation.

Explanation:

To solve for h in the equation S = 2πr^2 + 2πrh:

Start by subtracting 2πr^2 from both sides of the equation to isolate the term containing h.
This gives us 2πrh = S - 2πr^2.
To solve for h, divide both sides of the equation by 2πr.
The final step is to simplify the right side of the equation, giving us h = (S - 2πr^2) / (2πr).

Taylor and Morgan would like to spend some time on the river while camping with their family. Taylor wants to rent a two-person kayak. There is a $5 setup fee for kayak rentals and then kayaks are rented at $8 per hour. The setup fee for canoes is $9 and they are rented at $6 per hour. Determine the number of hours it takes for canoe rentals and kayak rentals to cost the same amount.

Answers

Answer:

After 2 hrs canoe rentals and kayak rentals cost would be same.

Step-by-step explanation:

Let the number of hours be 'x'.

Given:

Set up fee for Kayak rental = $5

Hourly rate for Kayaks rental = $8

Solution:

First we will find the total cost of Kayak rentals.

total cost of Kayak rentals can be calculated by sum of Set up fee for Kayak rental and Hourly rate for Kayaks rental multiplied by number of hours.

framing in equation form we get;

total cost of Kayak rentals = $5+8x$

Now Given:

Set up fee for Canoe rental = $9

Hourly rate for Canoe rental = $6

Now we will find the total cost of Canoe rentals.

total cost of Canoe rentals can be calculated by sum of Set up fee for Canoe rental and Hourly rate for Canoe rental multiplied by number of hours.

framing in equation form we get;

total cost of Canoe rentals = $9+6x$
