Answer:

Step-by-step explanation:
Given expression:

To evaluate the expression.
Solution.
The values are
Let
-----------1
Multiplying 10 both sides.
----------2
Subtracting 1 from 2.

- 
-------------------------------------------

Dividing both sides by 9.



Let 
Multiplying both sides by 100
------------3
Multiplying 1000 both sides.
----------4
Subtracting 3 from 4.

- 
-------------------------------------------

Dividing both sides by 900.


So, we can evaluate the given expression as:
⇒ 
⇒
⇒ 
Taking LCD = 900
⇒ 
⇒ 
Adding numerators.
⇒ 
⇒ 
⇒

Answer:
Step-by-step explanation:
What is the equation?
You need to replace all A with 3 and all c with 12. If I had the equation, I'd be glad to help further.
The Formula to find the Area of a circle using the radius is:

r = 8
So:



And you get about 201.06193
So, the area of a circle with a radius of 8 is about 201.06
Hope this Helps :)
You need to calculate 12% of 800.
To find a percent of a number, multiply the percent by the number.
Change the percent into a decimal by dividing the percent by 100 (move the decimal point of the percent two places to the left.)
12% of 800 =
= 12% * 800
= 0.12 * 800
= 96
Answer: 96 students
Answer:
A = P(1+r÷100)^n
where A is amount after some days
r is the rate
n is the number of years
p is the principle (the amount of money before the interest)
A = 5000 ( 1 + 12÷100)^5
A = 8811.70
A = 8812
