DanielleElmas [232]

Answer:

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 \times 4 = 14400 seconds

<u>By unitary method:</u>

150 friends get time in 5 activities = 14400

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

That means <u>each friend get 96 seconds in all 5 activities.</u>

Each friend get time on each activity = ?

Each friend get time on 5 activities = 96

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

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

jada goes to get her hair done the cost for a haircut and blowout is 65.42 she leaves a 25% tip for the stylist what is the tota
Art [367]

Answer:

The total cost is $81.78

Step-by-step explanation:

First lets calculate the tip

tip = cost * percent of tip

tip = 65.42*.25

tip = 16.355

Which rounds to 16.36  since we are working with money and round to the nearest cent

total cost = cost of cut and blowout + tip

                = 65.42 +16.36

                     =81.78
