Answer 2

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.

Answers

Answer:

Volume of a Cylinder:

In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.

Answer:

I thought of 24 and 14 and the larger number is 24

Step-by-step explanation:

24-16=8

The larger number will be "32".

Let the two numbers:

The first number be "32".

and,

The second number be "24".

By applying the subtraction between the above two numbers, we can find the difference between the numbers.

So,

→ [tex]32-24[/tex]

→ [tex]8[/tex] (difference)

We can see that the greater number between "32" and "24" is "32".

Thus the above answer is right.

Answers

Answer:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

Sandra

t = 1 year

I= $75

P= $2,500

r= ?

substitute in the formula above

75=2,500 (r(1))

solve for r

r=75/2,500)

r= 0.03

Convert to percentage form

r= 0.03 * 100 = 3%

Ron

t=1 year

I = ?

P= 8,000

r= 0.03

substitute in the formula of interest

I = 8,000(0.03 *1)

I = $240

is f(x) = x^3 - x even, odd, or neither. Explain your answer.

Answers

Odd function : f(-x) = -f(x)
Even function : f(-x) = f(x)

f(-x) = (-x)^3 = -x^3 = -f(x) thus it’s an odd function

Answer:

odd

Step-by-step explanation:

a function is even when f(-x) =f(x) and a function is odd

when f(-x)= -f(x)

so let's substitute -x into our function

f(-x)= (-x)^3 -(-x)

= -x^3 +1

so, f(-X)= -f(x)

therefore our function is odd
