She invited 150 friends. But she only had 5 activities for her friends and her party only lasted 4 hours. How much time will each friend get on each activity

19.20 seconds.

Step-by-step explanation:

Given:

She invited 150 friends.

But she only had 5 activities for her friends and her party only lasted 4 hours.

Question asked:

How much time will each friend get on each activity ?

Solution:

First of all convert 4 hours into seconds:-

1 hour = 3600 seconds

4 hours = 3600 4 = 14400 seconds

By unitary method:

150 friends get time in 5 activities = 14400

1 friend get time in 5 activities = 14400 150 = 96 seconds

That means each friend get 96 seconds in all 5 activities.

Each friend get time on each activity = ?

Each friend get time on 5 activities = 96

Each friend get time on 1 activity = 96 5 = 19.20 seconds

Thus, each friend will get 19.20 seconds on each activity.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

you probably already have the answer but anyways it's b. 15.0
