There are 4 classrooms for fifth grade and 4 classrooms for sixth grade at a school. Each classroom has 20 students. A teacher is planning a field trip for some fifth and sixth grade students at this school. The teacher knows the following information: 90% of fifth and sixth grade students have permission to go on the trip. 4 teachers are going on the trip. The school requires 1 parent volunteer for every 8 students going on the trip. Part A How many parent volunteers are needed to go on the trip? Show your work or explain your answer. Enter your answer and your work or explanation. Part B All of the students, teachers, and parents going on the trip must ride in a school bus. The teacher needs to reserve 1 school bus for every 44 people. How many school buses does the teacher need to reserve? Show your work or explain your answer. Enter your answer and your work or explanation

Answers

Answer:

18

Step-by-step explanation:

Fifth grade has 80 students and sixth grade has 80 students. so if you get 90% of both then you have 72 and 72. Add and divide by 8 and you have the answer of 18 parent volunteers going.

There are a total of 8 classrooms with 20 students each, for a total of 160 fifth and sixth grade students.

What is volunteer?

It is a person who does something, particularly helping others, voluntarily and without being forced or paid to do so.

Part A:

There are a total of 8 classrooms with 20 students each, for a total of 160 fifth and sixth grade students. 90% of them have permission to go on the trip, so:

0.9 x 160 = 144 students have permission to go on the trip

To calculate the number of parent volunteers needed, we divide the number of students by 8:

144 ÷ 8 = 18 parent volunteers needed

Therefore, the teacher needs to find 18 parent volunteers to go on the trip.

Part B:

The total number of people going on the trip is:

144 (students) + 4 (teachers) + 18 (parent volunteers) = 166 people

To calculate the number of school buses needed, we divide the total number of people by 44:

166 ÷ 44 = 3.77

Thus, as we can't reserve a fraction of a school bus, we round up to the nearest whole number. Therefore, the teacher needs to reserve 4 school buses.

Answer:

y=5x-3

Step-by-step explanation:

Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b

Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept

7=5(2)+b

Then you just solve for b

7=10+b

Answers

Answer:

45°

Step-by-step explanation:

The angles of any triangle add up to 180 degrees

then subtract the sum from 180 to get answer: 180-135=45

Answer:

45

Step-by-step explanation:

In a triangle the angles add up to 180 degrees. So, we can subtract 47 and 88 from 180. The result, 45, will be your final answer.
