Answer:

A constant is a defined value often portrayed as a number.

A variable is a value that can change and is often represented as a letter.

Step-by-step explanation:

For example:

In the equation ? = 10x + 3y + 17

10, 3, and 17 are all constants.

X and Y are both variables.

To reiterate, constants are known values that can NOT change while variables are unknown values that can change!

An architect increases the radius of a circle window by 20 percent. By what percent
ale4655 [162]

Answer: 44%

Step-by-step explanation:

For a circle of radius R, the area is written as:

A = pi*R^2

Where pi = 3.14

If we increase the radius by 20%, the new radius will be:

R´ = R + 0.20*R = 1.20*R

The new area will be:

A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2

   = 1.44*pi*R^2

And pi*R^2 = A, the original area, then_

A´ = 1.44*A = A + 0.44*A

This means that the percentage in which the area increased is:

0.44*100% = 44%
