What is 84 ft. to 84 sq ft.

2. The quotient of a number and -9 increased by 10 is 11.

MrMuchimi

Answer:

Step-by-step explanation:

This question isn't worded the greatest, there are two ways you can read this.

1. The quotient of a number and -9, increased by 10, is 11

2. The quotient of a number, and -9 increased by 10, is 11

The first equation will look like this

$\frac{x}{-9} +10 = 11$

And the second will look like this

$\frac{x}{-9+10} = -11$

So I have solved for both (I personally believe the second way of reading the question is the correct way)

Over the course of a year, a company goes from 115 employees to 124 employees.

just olya [345]

An equation that could be used to find the percent change, p, in the number of employees is:

$\begin{array}{l}{p=\frac{\text {change in number of employees}}{\text {previous count}} \times 100} \\\\ {\mathrm{p}=\frac{9}{115} \times 100}\end{array}$

<h3><u>Solution:</u></h3>

Given that, Over the course of a year, a company goes from 115 employees to 124 employees.

Given that "p" represents the percent change

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.

$\text { Percent change "p" }=\frac{\text { change in number of employees }}{\text { previous count }} \times 100$

Change in number of employees = present count – previous count

So, change in number of employees = 124 – 115 = 9

$\begin{array}{l}{p=\frac{9}{115} \times 100} \\\\ {p=\frac{9}{23} \times 20} \\\\ {p=\frac{180}{23}=7.82}\end{array}$

The equation that is used to find the percent change is:

$\begin{array}{l}{\mathrm{p}=\frac{\text { change in number of employees }}{\text { previous count }} \times 100} \\\\ {\mathrm{p}=\frac{9}{115} \times 100}\end{array}$

What is the sum of the interior angles of a decagon?

iren [92.7K]

I hope this helps you

n=360/exterior angle

10=360/exterior angle

exterior angle=36

36+interior angle=180

interior angle=144

sum of decagon interior angle

10.144

This one is hard! try your best please.

Answer:

1. 301.6 $in^{3}$

2. 576 $in^{3}$

3. 274.41 $in^{3}$

Step-by-step explanation:

We know that the diameter of one of the spheres must be 4 in, because the length of the box is 12 in and there are 3 spheres along each side, and $\frac{12}{3} =4$ . That means that the radius of a sphere is 2 in. Put 2 into the formula for the volume of a sphere, and then multiply your solution by 9, to get the total volume.

Then, you can find the volume of the box, because you know its dimentions are 12x12x4.

Subtract your answer for part 1 from your answer for part 2, and you have the solution to part 3. Hope this helps!! :-)
