Multiply 22 and 0 to get 0

Multiply 60 and 22 to get 1320

0 + 1,320 = 1,320

Step-by-step explanation:

When doing multiplication, you first start by multiplying the the bottom right number by the top right, then left numbers. In this case it’s 0, and multiplied by 0 is 0. In this case, since the first answer was 0, you just have to grab a calculator for 22 x 60

A dance student wants to know the favorite type of dance class for students at The Dance Academy. She surveys each student in her ballet class. In which way could the results of her survey be most improved? She could sample an equal number of students in each type of dance class. She could sample a proportional number of students in each type of dance class. She could sample one student in each type of dance class. She could sample one teacher from each type of dance class.

Answers

Answer: (B) She could sample a proportional number of students in each type of dance class.

Step-by-step explanation: 100%

The teacher should sample a proportional number of students in each type of dance class so that it possess all qualities of a good sample.

What is a good sample?

Firstly, the sample should be representative of the population. The teacher's goal is to determine the favorite type of dance class for students. Thus, sample should also consist of students only. This rules out option four. Sample cannot consist of teachers.

Secondly, the sample should be large enough to draw meaningful conclusions from it. This rules out option three. Sampling one student in each type of dance class will not give reliable results.

Third, the sample should be proportional. It will give truly accurate results id each unit or group of the population is fairly represented in the sample. Therefore, option two i.e., sampling a proportional number of students in each type of dance class is the best choice.

A proportional relationship is formed when y = 16 and x = 4. What is the value of y when x = 2? The relationship is assumed to be directly.

Answers

Answer:

x=7

Step-by-step explanation:

Answer:

y = 8

Step-by-step explanation:

Given the relationship is direct then the equation relating the quantities is

y = kx ← k is the constant of proportion

To find k use the condition when y = 16, x = 4, then

16 = 4k ( divide both sides by 4 )

4 = k

y = 4x ← equation of proportion

When x = 2, then

y = 4 × 2 = 8

Answer:

1. Multiply the tax rate by the sale amount to find the tax:

  0.04 × $251.99 = $10.08 . . . . sales tax on the dresser

2. The relation can be written as a proportion:

  area/bags = 150 m²/(0.5 bags) = A/(14 bags)

Multiply by 14 bags.

An employee named Bolarry in a restaurant makes $22.50 an hour. He gets a 12.5% raise (Markup). What does this man make for a weekly salary, if he works 6 hours a day, for 6 days a week?

Answers

Answer:

$911.25

Step-by-step explanation:

For 1 day the man works for 6 hours.

Then for 6 days the man will work for (6×6)hours = 36 hours

If the man makes $22.5 an hour, then for 36 hours, the man will earn ($22.5×36) = $810

Given, that the man gets a 12.5% raise, the we would have to apply the formula, where the 12.5% should be added to $810.

New Value/Old Value = 100 + rate/100

New Value/$810 = 112.5/100

By solving this equation, we get $911.25. So the man will earn $911.25 if he works for 6days a week.
