Shown below are the steps a student took to solve the simple interest formula A = P(1 + rt) for r.

asambeis [7]

To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:

A/P = 1 + rt.

Next, isolate rt by subtracting 1 from both sides:

A/P - 1 = rt

Finally, divide both sides by t:

A/P - 1

----------- = r

This could be written in other formats, such as:

A - P

-------- = r

A circle with a radius of 1/2 ft is dilated by a scale factor of 8. Which statements about the new circle are true? Check all th

AfilCa [17]

The circle is being dilated by a factor of 8 so the radius will be 8 times the original radius (4 ft).

The circumference of a circle = $2\pi r$ , so if r is replaced by $8r$ we get $C = 2\pi * 8r$ or just $C = 8*(2\pi r)$ .

Basically the circumference will be 8 times the original circumference.

If you plug in the original radius, into this new formula you get $C_{new} = 8*(2\pi * \frac{1}{2}) = 8\pi \: ft$

The area of a circle = $\pi r^2$ , so if r is replaced by $8r$ we get $A = \pi*(8r)^2$ or just $A = 64\pi r^2$

Basically the area will be 64 times the original area.

If you plug in the original radius into this new formula you get $A = 64\pi * (\frac{1}{2})^2 = 16\pi \: ft^2$

The answers are A, C, F, G, and H

Write As Percent

andrew-mc [135]

To make a fraction a percent, you have to divide the numerator by the denominator. You get a decimal. Multiply the decimal by 100 to get the percent or just move the decimal two places to the right.

So,

Divide 1 by 5 and you get 0.20

Multiply 0.20 by 100. The answer is 20%

Divide 2 by 3 and you get 0.6666.......

Multiply 0.6666..... by 100 and you get 66.6%

Divide 1 by 40 and you get 0.025.

Multiply 0.025 by 100 and you get 2.5%

Divide 4 by 8 and you get 0.5.

Divide 0.5 by 100 and you get 50%.

Divide 12/16 and you get 0.75.

Multiply 0.75 by 100 and you get 75%.
