Answer:
24π cm
Step-by-step explanation:
s = (∅/360) * 2πr
s = (216/360) * 2π(20)
s = (216/360) * 2 * 20 * π
s = 24π cm
That is a dodecagon, so x without context is 150.
Answer:
The answer is not complete. I will explain the concept of profit to you.
Step-by-step explanation:
We can determine profit deducting direct costs (cost price) of commodities from sales (selling prices) of the commodities.
Profit = Selling Price - Cost Price
Example:
A trader buys some dresses for #2,500 in May and agrees to pay for it in three months’ time. He sells off all the dresses in August for #4,500. The profit for the month is #2,000.
The formula for percentage profit is 
The formula for gross profit is Revenue – Cost of Sold Items
Profit Margin =
* 100
While Gross Profit Margin can be calculated as
* 100
Any of these formulas can be used to calculate profit-related questions.
Answer:
No, it is NOT a prime number.
Step-by-step explanation:
To find out if a number is a prime number, you can divide it by two. If it is a whole number, it isn't prime. It would be a mixed number/fraction if so.
<em>All prime numbers are whole numbers but the result of the division shouldn't be when you divide the number you want to find out. If it is a fraction/mixed number, your unknown number is most likely a prime number. (my explanation was confusing)</em>
Answer:
x^2 - 5
Step-by-step explanation:
x = -1, y = 1 - 5 = -4.
x = 0, y = 0-5 = -5.
x = 1, y = 1 - 5 = -4.
