If a sweatshirt cost $45, and sales tax is 7%, how much tax did you pay?
$48.15
Good Luck!!! :)
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

A window-washing crew can finish 15 windows in 18 minutes.
If this crew was assigned to wash all of the 24,348 windows on the outside of the Burj Khalifa at this rate, how long will the crew be washing at this rate?
Answer:

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 ---- ?

If y varies directly with x, and y = 2 when x = −4, what is the value of y when x = 20 ?
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

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.
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.

Answer:
$10.08 4200 square metersStep-by-step explanation:
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.
(14/0.5)(150 m²) = 4200 m² . . . area covered by 14 bags
