Answer:

\frac{6}{\sqrt 2}= 3\sqrt 2

Step-by-step explanation:

Given

\frac{6}{\sqrt 2}

Required

Rationalize

\frac{6}{\sqrt 2}

To do this, we simply multiply by \frac{\sqrt 2}{\sqrt 2}

\frac{6}{\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}

This gives:

\frac{6 * \sqrt 2}{\sqrt 2 * \sqrt 2}

\frac{6 \sqrt 2}{2 }

3\sqrt 2

Hence:

\frac{6}{\sqrt 2}= 3\sqrt 2

levacccp [35]

NikAS [45]

Answer:

47 meetings

Step-by-step explanation:

1. You know the company generates 100,000 dollars in profits, and pays 50,000 dollars to host the event, therefore, subtract both numbers to determine how much profit they make.

100,000 - 50,000 = 50,000 dollars

2. You now know that company generates 50,000 dollars in profits for each meeting

3. You also know that the company is aiming for a profit of 2.35 million, so you would divide the the goal by the total profits per meeting

2,350,000/50,000 = 47

It takes 47 meetings for the company to reach their goal.
