Answer:2

Step-by-step explanation:

Solve for n

Group like terms

3n+5n-27.1+7.1

8n-20=0

8n=20

n=20/8

n=5/2

For the sum to be negative n has to be greater than 5/2

And 2 is the solution

An international company has 29,100 employees in one country. If this represents 23.7% of the company's employees, how many empl
WINSTONCH [101]

Answer:

122785 employees.

Step-by-step explanation:

Let the total number of employees be X

Given the following data;

Number of employees = 29100

Percentage = 23.7%

To find the total number of employees;

23.7/100 * X = 29100

Cross-multiplying, we have;

23.7X = 29100 * 100

23.7X = 2910000

X = 2910000/23.7

X = 122784.81 ≈ 122785 employees

Converting (x - 4)^2 + y^2 = 16 into polar form
dimulka [17.4K]

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

(x - 4)² + y² = 16

Step 02:

polar form:

x = r cos (θ)

y = r sin (θ)

(r cos (θ) - 4 )² + (r sin (θ))² = 16

(r cos θ - 4)² + r² sin² θ = 16

r (r - 8 cos (θ)) = 0

r = 8 cos θ

The answer is:

r = 8 cos θ

A bag is on sale for $30. If the sale is 25% off, what was the original price of the bag? Explain your thinking
Eva8 [605]

Answer:

30x25/100

25%=7,5$

30+7,5$=37,5$

The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.

Hope this helps, have a good day!

Pls mark brainliest :))
