Emily has 7 cups of water in a jug.If she drinks 2/3 of a cup every hour.How long would it take her to drink the whole jug
zepelin [54]

It would take her 10.5 hours to drink the whole jug.

Step-by-step explanation:

Given,

Cups of water in jug = 7

Water drunk every hour = \frac{2}{3} of cup

Let,

x be the number of hours.

According to given statement;

\frac{2}{3}x=7

Multiplying both sides by \frac{3}{2}

\frac{3}{2}*\frac{2}{3}x=7*\frac{3}{2}\\x=\frac{21}{2}\\x=10.5

It would take her 10.5 hours to drink the whole jug.

Given a group of 17 people in a party, we consider the number of times a person shakes hand with someone else. Show that there i
aev [14]

Answer:

Step-by-step explanation:

Given that there is a group of 17 people in a party.  There takes place a number of hand shakes between them.

To show that there is always two people who shake hands with the same total number of people.

If possible let each person did a different number of handshake.

We know that since there are 17 people, there cannot be more than 16 hand shakes for any one in the group.

Hence if different hand shakes must be 0,1,2...16

Consider the last person having 16 hand shakes. He has shaken hand with each other person in the group thus making it clear that no one could have done 0 hand shakes.   Since we get a contradiction, our assumption was wrong. That is, there is always two people who shake hands with the same total number of people.

vivado [14]

This question is incomplete

Complete Question

A school held several evening activities last month—a music concert, a basketball game, a drama play, and literacy night. The music concert was attended by 250 people. How many people came to each of the other activities?

Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?

Answer:

350 people

Step-by-step explanation:

Percentage of people that attended a drama play =

Number of people that attended the drama play/Total number of people at the concert × 100

Attendance at the drama play was 140% of attendance at the concert.

The music concert was attended by 250 people

Let the number of people that came to the drama play = x

Hence:

140% = x/250 × 100

140/100 = x/250

Cross Multiply

140 × 250 = 100 × x

x = 140 × 250/100

x = 350 people

Therefore, the number of people that came to the drama play = 350 people
