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.

Step-by-step explanation:
Just made it up on the spot :)
Jared invited his friends over for lunch. He bought a pizza and ate 3/4 of it himself before calling his friends. He called Bob, Matombe, Steve, Owen, and Bill. Now, Jared must divide the 1/4 of the pizza into 5 parts for his friends to eat.
Answer:
Step-by-step explanation:
If 1/4 is divided by 5 we can think about it as 1/4 is a quarter of a whole and we need to divide that quarter in 5 equal parts.
Story Problem:
Alexa has 5 more days to finish reading the ELA book assigned by her teacher. She still has to read 1/4 of the book. What fraction of the book she should read on each of the 5 days to ensure she will be done in time?
(1/4 ) / 5 = (1/4) *(1/5) = 1 / 20
If Alexa reads 1/20 of the book each day she will finish the book in 5 days.

First you gotta add the cubes inside of it to find the volume then the ones outside you have to take them out and slant them then you have to fill the whole thing up and there you go [or you can just add all the numbers together for a easier explanation. ] Sorry if its wrong! ~Bread
Answer:
68 in³
Step-by-step explanation:
To find the volume of the figure, we first need to find the volumes of the 2 triangular prisms and 1 rectangular prism.
Triangular prism
[tex]{\boxed{\text{Volume}= \text{base area ×height}}}[/tex]
The base area here is the area of the triangular face, since it is the face that repeats itself throughout the entire length/height to form the volume of prism.
Base area
= area of triangle
= ½(base)(height)
= ½(2)(3)
= 3 in.
Height= 2 in.
Volume
= 3(2)
= 6 in³
Volume of rectangular prism
Volume
= base area ×height
= length ×breadth ×width
= 14(2)(2)
= 56 in³
Total volume
Volume of figure
= 2(6) +56
= 12 +56
= 68 in³

Answer:
It could be the probability or this for an example: 1/2 = an equal chance of getting 1 or 2, 3/4 = likely, 1/4 is going to be unlikely since you have a lower chance of something, and 4/4 = 1 = a certain chance of something happening.

According to the frequency table, what is the mean of the score?
Round your answer to the nearest tenth.
A) 6.0
B) 6.1
C) 6.2
D) 6.3
The mean of the scores is approximately 6.2. The correct answer is (C).
What is arithmetic mean?The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
To calculate the mean of the scores based on the given frequency table, we need to multiply each score by its corresponding frequency, sum up the results, and then divide by the total frequency.
Let's perform the calculations:
(1 x 1) + (2 x 1) + (3 x 3) + (4 x 1) + (5 x 4) + (6 x 5) + (7 x 6) + (8 x 5) + (9 x 3) + (10 x 1) = 167
1 + 2 + 9 + 4 + 20 + 30 + 42 + 40 + 27 + 10 = 185
The total frequency is 1 + 1 + 3 + 1 + 4 + 5 + 6 + 5 + 3 + 1 = 30
Now, we divide the sum (185) by the total frequency (30) to find the mean:
185 / 30 = 6.1667
Rounding this value to the nearest tenth, the mean of the scores is approximately 6.2.
Therefore, the answer is C) 6.2.

The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
Answer:
1) The length of the entire walkway to the nearest hundredth of a yard is 50.24 yds
2) 50.24 is a rational number
Step-by-step explanation:
1) To calculate the length of the walkway, you need to find "b"
the value of b using the Pythagoras theorem can be written as,
D²=12²+b²
15²=12²+b²
225=144+b²
b²=81
b=9
the value of each of the four hypotenuses can be written as,
A = [tex]\sqrt{12^2+8^2}[/tex] = [tex]\sqrt{208}[/tex] = 14.422
B = [tex]\sqrt{6^{2} +8^{2} }[/tex] = [tex]\sqrt{100}[/tex] = 10
C = [tex]\sqrt{6^2+9^2}[/tex] = [tex]\sqrt{117}[/tex] = 10.82
D = 15
Adding the value of all the hypotenuse to get the length of the walkway, therefore, the length will be,
14.422 + 10 + 10.82 + 15 = 50.24
So, the entire walkway to the nearest hundredth is 50.24
2) Because Irrational numbers are ones that never end.
50.24 is a nice, round number, even though its a decimal.
Answer:
50.24 - rational number

___ sold ___ more rings than ___
Jacob 5 lou
lou 8 jacob

15
Answer:
Lou sold 5 more earings than JacobStep-by-step explanation:
Step 1
Find 20% of 200
For fraction: divide 20 by 100 and remove the % sign.
[tex]{20}\%=\frac{20}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
[tex]{20}\%=0.2[/tex]
Multiply the decimal or fraction by the quantity that equals 100%
[tex]100[/tex]%[tex]=200[/tex]
[tex]\frac{20}{100} *200=0.2*200=40[/tex]
20% of 200 is 40
Lou sold 40 rings
Step 2
Find how much more or less earings did Lou sell than Jacob
40-35=5
So Lou sold 5 more rings than Jacob
Final Answer:Lou sold 5 more earings than Jacob

A carpenter lays 15 ft2 of tile in 35 of an hour.
How many square feet of tile does the carpenter lay per hour?
Enter the correct answer in the box.
Answer:
16 is equivalent to 2/3 therefore you just multiply by 3/2 because 2/3 times 3/2 gives you one which would give you the number of square feet per hour and x would be the amount of square feet per hour made. To show in steps...
16=2/3x
16(3/2)= 2/3 (3/2)

Leena pulls a blue tile out of a bag of same-size tiles without looking. There are 4 purple tiles, 6 blue tiles, and 8 green tiles left in the bag. Find the theoretical probability that the next tile she picks is the same color and the probability that it is a different color. Is it likely the next tile she picks will match?
Answer:
1/3
Step-by-step explanation:
To find the probability of finding a blue tile you have to find blue tiles over the total number of tilesFirst, we have to find the total amount of blue tiles
4 purple 6 blue 8 green
we have 6 blue tiles
Next, we have to find the the total amount of tiles
4+6+8=18
Now, we put it as a fraction then simplify

Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.
Answer:
Unit Cubes = 125 in
Volume = 125 in
Step-by-step explanation:
To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.
Volume of rectangular prism = length x width x height
Advance explanation:
The formula to find the volume of the rectangular prism is this:
L x W x H = V
L = Length = 5 in
W = Width = 5 in
H = Height = 5 in
V = Volume = 125
You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In
Hope this helps!

Multiply the Length and Width with the Height (L x W x H).Your answer will be the result of the equation.Answer:

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.
Answer:
The point closest to the number 40
Step-by-step explanation:
To find volume of cone:
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
(but in this case we will be substituting [tex]\pi[/tex] for it approximation: 3.14)
So our new equation is [tex]V= 3.14r^{2} \frac{h}{3}[/tex]
All right, let's get to work now.
Following the order of operations our first step would be: [tex]3^{2}[/tex] or 3x3 wich is 9Next step would be 3.14x9, which is 28.26After that we would solve [tex]\frac{4}{3}[/tex], which is 1.3 repeating but we can round to the nearest tenth and get 1.3Next we would multiply 28.26 by 1.3 which is 36.73800We would next round to the nearest whole and our final answer is: 37
