Step-by-step explanation:

The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:

If:

15 windows ---- 18 min

28601 windows ---- ?

Then:

? = (28601windows)(18min)/15windows

? = 34321.2min

Answer:

The answer is 10.9

Step-by-step explanation

#1 think of the formula of the area

length x width = area

#2 do the oposite of what you would to to find the area to find the width

82.84➗7.6 = 10.9

#3 check your answer

7.6 x 10.9 = 82.84

#3 answer

width= 10.9

Answer:

1.4 or 30.8

Step-by-step explanation:

1.4 is for regular math because it's basically 16.1 - 14.7

30.8 is for KCO or Keep Change Opposite (Beginners math)

Basically it would turn the equation into 16.1 + 14.7

You can use either but if you aren't sure ask your teacher about the strategy.

Hope this helps and if not tell me your strategy.

Answer:

1,320

22 and 0,

6 and 22

0 + 1,320 = 1,320

Hope I helped! Plz leave a comment or rating to help me!

Answer:

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

Answer:

Step 1: take the total price and divide it by one plus the tax rate.

Step 2: multiply the result from step one by the tax rate to get the dollars of tax.

Step 3: subtract the dollars of tax from step 2 from the total price.

Pre-Tax Price = TP – [(TP / (1 + r) x r]

TP = Total Price

Answer:

y=kx

2=k.-4

k=-1/2

then

y=-1/2×20

y=-10

Answer:

y = - 10

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 2 when x = - 4, that is

2 = - 4k ( divide both sides by - 4 )

[tex]\frac{2}{-4}[/tex] = k, that is

k = - [tex]\frac{1}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] x ← equation of variation

When x = 20, then

y = - [tex]\frac{1}{2}[/tex] × 20 = - 10

Answer:

v=7

Step-by-step explanation:

add 15 to both sides 5v-15+15=20+15

simplify

5v=35

divide both sides by 5

5v/5 = 35/5

and you get 7

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.

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.
