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?

Answers

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.

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

Answers

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.

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

Answers

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
