In a group of 15 children the ratio of the boy : the girl is 2: 3: 5 more girls join the group. Calculate the percentage of boys in the new group. What is the percentage decrease for the boys? Find the increase percent of the girls

Step-by-step answer

P Answered by PhD

Percentage of new group boys = 30%

Percentage decrease for the boys = 10%

Increase percent of the girls = 10%

Step-by-step explanation:

Given:

Number of children = 15

Ratio (Boys to Girls) = 2 : 3

Number of more girls join = 5

Find:

Percentage of boys in new group

Percentage decrease for the boys

Increase percent of the girls

Computation:

Number of boys = 15[2/5]

Number of boys = 6

Number of girls = 15[3/5]

Number of girls = 9

Percentage of boys = [6 / 15]100

Percentage of boys = 40%

Percentage of girls = [9 / 15]100

Percentage of girls = 60%

New number of students = 15 + 5

New number of students = 20

New number of boys = 6

New number of girls = 9 + 5 = 14

Percentage of new group boys = [6 / 20]100

Percentage of new group boys = 30%

Percentage of new group girls = [14 / 20]100

Percentage of new group girls = 70%

Percentage decrease for the boys = 40% - 30%

Percentage decrease for the boys = 10%

Increase percent of the girls = 70% - 60%

Increase percent of the girls = 10%

1. A middle school conducted a survey of students to determine if they spent more of their time playing games or watching videos their tablets. The results are shown in the table below. Boys Girls Total Playing Watching Total Games Videos 138 46 184 54 142 196 192 188 380 Of the students who spent more time playing games on their tablets, approximately what percent were boys?

Step-by-step answer

P Answered by Master

Students = 192

$\%Boys = 72\%$

Step-by-step explanation:

Given

See attachment for proper table

Solving (a): Students who spend more time playing games on tablets

To do this, we simply consider the playing games column.

The student are:

Students = 192

Solving (b): The percentage of boys.

From the same columns, the numbe of boys are:

Boys = 138

So, the percentage is:

$\%Boys = \frac{Boys}{Students}* 100\%$

$\%Boys = \frac{138}{192}* 100\%$

$\%Boys = 0.71875* 100\%$

$\%Boys = 71.875\%$

Approximate

$\%Boys = 72\%$

A survey of 200 school children classified students by gender and the number of times Sharky s Soda was purchased each month at school. Examine the chart below, where each respondent is classified according to the two criteria. - What percentage of boys bought 1 Sharky s? What percentage of girls bought 2 or more Sharky s? -What percentage of people bought no Sharky s? -How would you characterize the relationship between boys that purchased Sharky s and the total of people buying 2 or more Sharky s Soda?

Step-by-step answer

P Answered by Specialist

15%

65%

7.5%

Step-by-step explanation:

1.) Percentage of boys who bought 1 Sharkys

Number of boys that bought 1 sharkys = 15

Total number of boys = 100

= 15 / 100 * 100% = 15%

2.)

Percentage of girls who bought 2 or more sharkys :

Number of girls who bought 2 or more sharkys

= 65

Total number of girls = 100

= 65 / 100 * 100% = 65%

3.)

Percentage of people who bought no sharkys

Number of people who bought no sharkys = 15

Total number of people = 200

15 / 200 * 100% = 7.5%

The CBGC pays college and high school students $5.75 per hour to tutor the younger boys and girls. If one of those tutors works 3.4 hours on Monday and 2.7 hours on Thursday, what will the tutor earn for the week? Type here If the Club has a tutoring budget of $250 per week, how many tutoring hours can be provided? Type here Dany is tutoring Abe. Below are the results of two check-up quizzes. Write the score of Abe s first quiz (21 out of 30) as a percent. Type here Abe is pleased with his improvement on the second check-up. He says he has made

1. $35.075

2. 43.5 hours

3. 70%

4. Danny is correct

5. Abe's score out of the 30 points of the last quiz to get an overall checkup quiz grade of 80% should be 28.5

Step-by-step explanation:

The pay per hour for student tutors = $5.75

1. A tutor who worked 3.4 hours on Monday and 2.7 hours on Thursday has worked, 3.4 + 2.7 = 6.1 hours for the week, therefore

The week earning for the tutor = 6.1 × 5.75 = $35.075

2. The Club's tutoring budget per week = $250

The number of tutoring hours that can be provided per week is given by the relation;

$\frac{The \, Club's \ tutoring\ budget \ per \, week}{The \, pay \ per \, hour\, for\, student\, tutors} = \frac{\$250}{\$5.75/hour} = 43.47826 \approx 43.5 \, hours$
