At every company meeting, the president speaks for 20 minutes and then takes questions from her employees. Let q represent the n

ololo11 [35]

Answer:

t = 20 + q (minutes)

Step-by-step explanation:

The meeting consists of speaking and Question & Answer (Q&A) sessions.

Speaking session = 20 minutes

Q&A session = q minutes

Total number of minutes spent for the two sessions = 20 + q (minutes)

But total number of minutes meeting lasted = t minutes.

Therefore, t = 20 + q (because they both represent the total number of minutes the meeting lasted)

Determine the volume of the rectangular prism.<br>

Flauer [41]

Answer:

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2 $\frac{1}{2}$ and the height is 2 $\frac{1}{2}$

8 × 2 $\frac{1}{2}$ × 2 $\frac{1}{2}$

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2 $\frac{1}{2}$ = 20

20 × 2 $\frac{1}{2}$ = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>
