Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel. How long would it take Russel to build the shed if he were to work alone?

Answer:

32 hours.

Step-by-step explanation:

Let x represent the time taken by Russell and Aaron to build the shed.

We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.

Russell's work rate would be .

Since Aaron works three times as fast as Russel, so Aaron's work rate would be .

Part of work done by in one hour would be .

We can represent our given information in an equation as:

Let us solve for x.

Therefore, it will take Russell 32 hours to build the shed working alone.

about 2 out of every 3 people son lee apeaks to agrees tonsign the petition. if she speaks to 150 people about how many signatures will she get?

Lee will get 100 signatures if she speaks to 150 people.

What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

If 2 out of every 3 people that Lee speaks to agree to sign the petition, and she speaks to 150 people, then she will get the number of signatures as:

⇒ (2/3) × 150

Apply the multiplication operation,

⇒ 300/3

Apply the division operation, and we get

⇒ 100

Thus, she will get 100 signatures.

What number can you cube to make it bigger than 200 but smaller than 400

If you would like to cube one number and make it bigger than 200 but smaller than 400, you can find the number using the following steps:

n ... the number

200 < n^3 < 400

For example:

If n equals to 6, then n^3 = 6^3 = 6 * 6 * 6 = 216 and 200 < 216 < 400, so the result could be 6.

If n equals to 7, then n^3 = 7^3 = 7 * 7 * 7 = 343 and 200 < 343 < 400, so the result could also be 7.

But, if n is 8, then n^3 = 8^3 = 8 * 8 * 8 = 512 and 512 > 400.

Result: You can take the numbers 6 and 7.

n ... the number

200 < n^3 < 400

For example:

If n equals to 6, then n^3 = 6^3 = 6 * 6 * 6 = 216 and 200 < 216 < 400, so the result could be 6.

If n equals to 7, then n^3 = 7^3 = 7 * 7 * 7 = 343 and 200 < 343 < 400, so the result could also be 7.

But, if n is 8, then n^3 = 8^3 = 8 * 8 * 8 = 512 and 512 > 400.

Result: You can take the numbers 6 and 7.

Intercept Form: y=2(x+3)(x-5)

Standard Form?

Vertex Form?

I'm not sure but,

Intercept Form to Standard:

y=2(x+3)(x-5)

y=[x^2-5x+3x-15]

y=[x^2-2x-15]

y=2x^2-4x-30

Standard Form to Vertex:

y=2x^2-4x-30

y=2(x^2-4)-30

y=(x^2-4x+4x)-30-4(-2)

y=2(x-2)^2-22

If a crew of 4 workers complete the job in 10 hours, how long will it take 5 workers to complete the same job?

We can solve using proportions

or 4 works is to 10 hours as 5 workers is to x hours.

to solve we cross multiply to get

so it will take 5 men 12.5 hours!

2/5 divided by 9/10 A. 2/5

B. 4/5

C. 2/9

D. 4/9

actually 0.00444444444 as a fraction

It would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!

HIGH SCHOOL GEOMETRY/ ALGEBRA The areas of two squares are in the ratio 25:36. What is the ratio of their perimeters? Express your answer in the form a:b.

Answer:

The ratio of the lateral sides and perimeters = the ratio of square root of their areas

Then, the ratio of the sides and the perimeters is 6:5 or if this is wrong it it is 5:6
