The cost of a cleaning service includes labor and supplies. Supplies are 30% of the total cost. The cost of supplies for a certain cleaning service is $54.
What is the total cost of the cleaning service?
Enter your answer in the box.
Answer:
The total cost of the cleaning service is $180
Step-by-step explanation:
We have, 30% × x = 54
or,
30/100 × x = 54
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 54 × 100/30
x = 180
If you are using a calculator, simply enter 54×100÷30, which will give you the answer.

Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.
To find x, we can use some facts from geometry and trigonometry.
• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.
• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.
• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.
• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have
tan(70°) = 12 / (x/2)
and solving for x gives
tan(70°) = 24/x
x = 24/tan(70°)
x = 24 cot(70°) ≈ 8.7
Then the total area of the nonagon is
54x = 54 • 24 cot(70°) ≈ 471.7

Answer: 4 inches
Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4
Based on the calculations, the height of this pyramid is equal to: D. 36 inches.
Given the following data:
Volume of pyramid = 1,944 cubic inches.Dimensions of rectangular base = 18 inches by 9 inches.How to calculate the height of this pyramid?Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × b × h
Where:
b is the base area.h is the height.For the base area, we have:
Base area = length × breadth
Base area = 18 × 9
Base area = 162 square inches.
Substituting the given parameters into the formula, we have;
1,944 = 1/3 × 162 × h
1,944 = 54h
h = 1,944/54
Height, h = 36 inches.

A tank can be filled in 22 and a fifth minutes. What fraction of it will be filled in 21 min
Answer:
I believe the answer is about 95 percent.
Step-by-step explanation:
The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...
22 1/5 over 100 = 21 over x
Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer
What I just wrote is the rule of proportions
Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

Explain your answer.
Answer:
60%
Step-by-step explanation: Because the graph flattens out at about 60% meaning that that is the most likely percentage.
A weather forecast states that there is a 20% probability of rain on each of the next 3 days.
Complete the description of a simulation you could perform using random numbers to find the experimental probability that it will not rain on any of the next 3 days.
To simulate a 20% probability of rain over 3 days, let

of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.

Answer:
The perimeter is 380 ft^2.
Step-by-step explanation:
To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.
To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.
Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

Answer:
9 days
Step-by-step explanation:
1 day: 5/6 2 days: 10/6 3 days: 15/6 4 days: 20/6 5 days: 25/6
6 days: 30/6 7 days: 35/6 8 days: 40/6 9 days: 45/6
If you divide 45 and 6 by 3 you get 15/2. If you put 15/2 into a mixed number you would get 7 1/2. So 9 days would be your answer.
Answer:
7 1/2 bottles will last 9 days
Step-by-step explanation:
To answer this, divide '7 1/2 bottles' by '5/6 bottle per day:"
7 1/2 bottles
-----------------------
5/6 bottle/day
The unit "bottle"/"bottles" cancel, and so we are left with
7 1/2 day
------------------- and this is equivalent to 15 days/2 divided by 5/6 OR
5/6
15 days/2 times 6/5:
15(6)
--------- days = 18/2 days = 9 days (answer)

7 1/2 bottles will last 9 days.

Step-by-step explanation:

From the triangles given, ∆ DEF was dilated to ∆ ABC
The dilated triangle is = ∆ ABC
To find the scale factor uses for the dilation of the triangle, the length of the triangle AC and DF are considered.
AC from the scale= -2 -(-7)
= 7-2= 5
DF= 9-6.5
= 2.5
Therefore the scale factor = 5/2.5 = 2
And since the scale factor of dilation is 2 this means that ∆ A' B' C' can be translated to the 0.5 by 2 units.
