There are 9 people that have a conversation with each other exactly one time.

Sedbober [7]

The question is an illustration of arithmetic sequence.

<em>The number of conversation for 19 people is 171</em>

<u />

<u>(a) 9 people</u>

$Total = \frac{9 \times 8}{2}$

9 represents the number of people

8 represents the number of conversation each person had

2 represents the number of people having a conversation at once (i.e 2 people at once)

<u>(b) 19 people</u>

We have:

$n = 19$

The number of conversation is:

$Total = \frac{n \times (n -1)}{2}$

So, we have:

$Total = \frac{19 \times (19 -1)}{2}$

$Total = \frac{19 \times 18}{2}$

$Total = 19 \times 9$

$Total = 171$

Hence, the number of conversation for 19 people is 171

She spent 1/6 of it on snacks and 1/3 of it on a new book. She saves the rest. What fraction of the money did she save?

Doss [256]

Answer:

Step-by-step explanation:

<em>First step is that you need to have the same denominators so 1/3=2/6</em>

<em>If she spent 1/6 on snacks and 2/6 on a book which means she spent 3/6</em>

<em>so the fraction of what she saved is 3/6 or 1/2</em>
