Solve the formula for the specified variable
A=p+prt solve for r

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

The first step is to take p on both sides:

A - p = p + p*r*t - p

On the right hand side, cancel p and -p, since p-p=0. The equation will be:

A - p = p*r*t

Then, divide both sides of the equation by p*t:

(A-p)/(p*t) = (p*r*t)/(p*t)

On the right hand side, p*t can be cancelled:

(A-p)/(p*t) = r
Answer 2
Answer:

Answer:

r=A-p     (the line is the bar so this is a-p over pt)

    pt

Step-by-step explanation:

P+Prt=A

     

Prt=A−P            isolate the term which contains  r

   

Prt=A−P

divide pt by each side

Owen draws the cube shown. Pat draws a cube with a side length that is 3 unitsgreater than the side length of Owen’s cube. Carly draws a cube with a side
length that is 1/2 the side length of Pat’s cube. What is the volume, in cubic inches, of Carly’s cube?

Answers

Answer:

  • The volume of Carly's cube is 125 in³

Explanation:

The volume of a cube is calculated as the length of the side raised to the cube:

  • Volume = side³

1. Cube drawn by Owen

From the drawing:

  • Side = 7 in

2. Cube drawn by Pat

Side length  is 3 units greater than the side length of Owen’s cube:

  • Side = 7in + 3in = 10 in

3. Cube drawn by Carly

Side length is 1/2 the side length of Pat’s cube:

  • Side = (1/2) × 10 in = 5 in

  • Volume = (5 in)³ = 125 in³

Factor the given expression. 64^3-343

Answers

Your answer is 261201

63³-343 = 261801

Factor the following integer:

261'801

The sum of the digits of 261801 is 2 + 6 + 1 + 8 + 0 + 1 = 18, which is divisible by 9. This means 261801 is too.

261801 = 9×29089:

261801 = 9×29089

9 = 3^2:

261801 = 3^2×29089

Because 29089 is odd, only test odd numbers for divisibility.

29089 is not divisible by 3, 5, 7, 9, 11, 13, 15 or 17.

29089 = 19×1531 which means 29089 is divisible by 19:

261801 = 3^2×19×1531

3 is prime:

261801 = 3^2×19×1531

Because 19 is odd, only test odd numbers for divisibility.

19 is not divisible by 3.

Since 19 is not divisible by any integer up to 4, it is prime:

261801 = 3^2×19×1531

Because 1531 is odd, only test odd numbers for divisibility.

1531 is not divisible by 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39.

Since 1531 is not divisible by any integer up to 39, it is prime:

261801 = 3^2×19×1531

There are 2 copies of 3, 1 copy of 19 and 1 copy of 1531 in the product:

Answer: 261801 = 3^2×19×1531
