Answer: 48π ft2

Step-by-step explanation: The formula for area of a circle is A = πr2. The radius of each rug is 4 feet. We substitute 4 into the formula and we get 16π ft2. Multiply by three to find the total area covered is 48π ft2

Answer is D.) 48π ft²

Given:
3 circular rugs.
radius: 4 ft

Area of a circle = π r²
A = 3.14 * (4ft)²
A = 3.14 * 16ft²
A = 50.24 ft² 

Total area of 3 rugs

50.24 ft² * 3 rugs = 150.72 ft²

Equation leaving π.

150.72ft² ÷ 3.14 = 48ft²

D.) 48π ft²

1.) Some banks charge a fee on savings accounts that are left inactive for an extended period of time. The equation y = 5000 * (
oee [108]

Answer:

a. The initial amount of money that was left in this savings account was of 5000.

b. Decrease of 2% each year.

Step-by-step explanation:

Exponential function:

An exponential function, with an initial value of A(0), and a decay rate of r, as a decimal, is given by:

A(t) = A(0)(1-r)^t

In this question, we have:

y = 5000*(0.98)^x

a. What was the initial amount of money that was left in this savings account?

This is y(0) = 5000

The initial amount of money that was left in this savings account was of 5000.

b. What is the percent of change each year in this savings account?

First as a decimal.

1 - r = 0.98

r = 1 - 0.98

r = 0.02

So a decrease of 2% each year.

What is the result of 1/10 of 40?
WARRIOR [948]
This is not a difficult question and I will help you solve it :)

When calculating 1/10 from 40, what we have to do is this:

(1/10) * 40 = 4 

This means that we have to multiply 40 by 1 and divide by 10 :)

So the answer in this case is 4.
