Write a real-world problem that could be represented by the expression 3(23). Then explain how you could solve the problem mentally.

Answers

3(23) really means 3*23, or just 3 multiplied by 23. For example: "Jana has 23 dollars. Her friend John has $23, and his friend Jacob also has 23 dollars. How much money do they have all together?" To solve this problem mentally, you could break 3*23 into two numbers you're familiar with multiplying, like 20 and 3, and then add the numbers together. For example: 3*20 + 3*3. 3*20=60, 3*3=9, and 60+9=69. So, 3*23=69.

A middle school principal wants to change the lunch menu at the school. The principal surveys the students to determine how the students would feel about the changes. Which survey method will produce the best representative sample? A: survey every fifth student who rides in a car to schoolB: survey 3 randomly selected students from every homeroomC: survey every tenth seventh grade student during lunchD: survey 5 randomly selected students from every art, drama, and music class

Answers

The survey method that should generate the best representative sample should be option b.

Best survey method:

It is considered to be the best way for survey since all the other should contain the sort of the variable.

Also, the principle should not know who purchased the lunch and who does not so here the kids should be asked who ride the car since the kids who ride the buses or the 7th grade students.

So based on the above information, we can say that the option b is correct.

Answer:

B: Survey 3 randomly selected students from every homeroom.

Step-by-step explanation:

This would be the best way to survey, because all the others have some sort of variable. The principle doesn't know who buys lunch and who doesn't, so why would he just ask kids who ride in a car as there are kids who ride buses, or only 7th grade students, so the best answer would be something that everyone has, like homeroom.

What is the total weight of the water in the pool when it is completely filled?

V = L * W * D
V = 18 * 9 * 54/12
V = 18 * 9 * 4.5
V =729 cubic feet

729 cubic feet of water times 62.4 pounds = 45489.6 pounds
