The earth has a diameter of 7926.41 miles. what is the circumference of the earth?

frutty [35]

Circumfrence is to a circle as perimeter is to a polygon. The circumfrence of a circle always equals the diameter (or two times the radius, since the radius is half of the diameter) times pi.

The circumfrence would be 7926.41π miles because of this.
Should you round pi to 3.14, the circumfrence would be 7926.41 * 3.14.
This is equal to 24888.9274 miles. (round that if needed)

A newly launched clothing line is rapidly increasing in popularity. Every month 20% more items of clothing are sold. If 70,800 i

prohojiy [21]

Answer:

212,400 items were sold in 10 months.

Step-by-step explanation:

Given:

Items sold this month = 70,800

Percent Increase in every month = 20%

We need to find number of items sold in coming 10 months.

Solution:

First we will find number of items increase in each month.

number of items increase in each month can be calculated by Percent Increase in every month multiplied by Items sold this month and the divided by 100.

number of items increase in each month = $\frac{20}{100} \times 70800 = 14,160$

Now we will find number of item sold in 10 months.

number of item sold in 10 months is equal to sum of Items sold this month and number of items increase in each month multiplied by 10.

framing in equation form we get;

number of item sold in 10 months = $70800+10\times 14160 = 212,400$

Hence 212,400 items were sold in 10 months.

The amount of revenue in dollars, y, that Amahd receives from selling x posters is given by the equation y = 4x. The cost of pro

n200080 [17]

Answer: B: 20

Step-by-step explanation:

You are given two functions that are both equal to y. What you would do is set each function equal to y and solve:

4x=3/2x + 50

Next you would subtract 3/2x to isolate the x to one side:

5/2x=50

Then you would multiply by 2/5 to get rid of the fraction so all you’re left with is x=__

x=20

Hope this helps!
