Nester needs a cover for his circular outdoor pool. The circumference of the cover must be 16 meters. Which quantity is closest to the area of the pool cover measured in square meter?
Answer: 200.96
A - C/r, d = 16 ⇒ r = 8
A = (16π/2) (8)
= 8π (8) = 64π
A = 64 (3.14) ?
64 (3.14) = 200.96

The library raised $320,100 when 400 books were sold per day.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of days book sale = 4
The library paid for advertisement each day = $25
Cost of each book (b) = $2.00.
The expression represents the amount of money the library raised at the book sale.
= 4(25) + 2b(400)
Now,
Substitute b = 400 into the expression.
= 4(25) + 2(400)(400)
= 4(25) + 320000
= 320100
Therefore,
The library raised $320,100 when 400 books were sold per day.

Which expression shows another way to write 36+16?
4(9)+4
4(9+4)
6(6+8)
(6+4)(6+4)
Answer:
36+16= 52
4(9)+4= 40, which does not equal 52.
4(9+4) = 52.
6(6+8) = 84, which does not equal 52.
(6+4)(6+4) = 100, which does not equal 52.
So, 4(9+4) is correct.
