Answer: Hope this helps you!

6th floor

Step-by-step explanation:

<em>If it starts on the 9th floor and goes down 7 floors that is:</em>

9 <em>(9 floors) </em>+ -7 <em>(down 7 floors)</em>

<em>which is also equal to 9-7</em>

9-7 = 2

<em>Next, we need to go up by 4 floors starting with 2, 2+4</em>

2+4 = 6

How to solve -6&lt;-2x&lt;14
algol13
Hey there! :) 

-6 < -2x < 14

We're trying to solve for x. To solve for x, we must isolate x.

So, let's divide everything by -2!

-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2

**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **

3 > x > -7

So, our answer is : → 3 > x > -7

the volume of a cylinder is 411π in^3. The height of the cylinder is 9 in. Calculate the diameter of the cylinder to the nearest
EleoNora [17]

Answer:

13.5 in, or 34.3 cm.

Step-by-step explanation:

First, use the formula volume = pi * r^2 * height- you have the volume, so just solve the equation 411pi = pi * 9 * r^2 for r, and you get that r = 6.75. Since diameter is equal to 2r, multiply 6.75 by 2 to get your answer of 13.5 inches. The questions asks for the diameter in centimeters though, which makes it 34.3 cm.

Hopefully this helps- let me know if you have any questions!
