if a company has 5 employees with annual saleries of $40,000, $50,000, $40,000, $60,000 and $90,000 what is the mean anulal sala

krek1111 [17]

To find the mean of something, add all the numbers then divide by the number of numbers there are.
40,000 + 50,000 + 40,000 + 60,000 + 90,000 = 280,000
Then divide:
280,000/5 = 56,000

The mean of the annual salaries at the company is 56,000

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches

pashok25 [27]

Answer:

Option 1st is correct

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$

Step-by-step explanation:

Area of the triangle is given by:

$A = \frac{1}{2}bh$

where,

A is the area of the triangle

b is the base and

h is the height of the triangle.

As per the statement:

For a project, you need to make three triangles out of cardboard.

Each triangle has a height of 5 inches and a base of 10 inches

⇒b = 10 inches and h = 5 inches

$\text{Area of each triangle} = \frac{1}{2} \cdot 10 \cdot 5$

Since, you need to make three triangles out of cardboard

⇒ $\text{Area of 3 triangle}(x) =3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)$

Therefore, an equation can you use to solve for the total amount of cardboard you will need is,

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$
