On solving the provided question, we can say that difference of cylinder between the height of the soap 8 cm.
what is cylinder?One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.
[volume of cylinder]=pi*r²*h- = h=[volume of cylinder]/(pi*r²)
Volume=5652 cm³
r=7.5 cm, so, h= [tex][5652]/(3.14*7.5²) = h=32 cm[/tex]
the height of the soap in the full dispenser is 32 cm
the height when 4,239 cubic centimeters of soap remains in the dispenser is h [tex]=[4239]/(3.14*7.5²) = h=24 cm[/tex]
the difference is [tex]32-24 = 8 cm[/tex]
the answer is
8 cm

How to calculate area?step1
Perimeter of square = 40m
We have given that perimeter of square is 40m. To find its area, we have to calculate its side first.
Perimeter of square = 4× side
Substituting values in formula
Area of square = 4 × side
=> 40 = 4 × side
=> side = 40÷4
=> side = 10m
Side of square is 10m.
step 2
Calculating area of square :
We found that side of square is 10m. To find it area, required formula is:
Area of square = (side)²
To find area, substitute values in formula :-
Substituting values in formula :-
Area of square = (side)²
=> Area of square = (10)²
=> Area of square = 10 × 10
=> Area of square = 100m

52 = Total collection
Because the total is 52, the equation would be x + 3x + 4 = 52. Add the like terms to get 4x+4=52. Subtract 4 on both sides to get 4x=48. Divide 4 on both sides to get x = 12. Because Maci's collection is 3x, she should have 36 earrings.

rotation 180° about the center of symmetryreflection across the horizontal and vertical lines through the center of symmetry, in either orderreflection across any horizontal line, translation to the left, and translation up or down to final position (depending on where the horizontal line is)Step-by-step explanation:
The question is asking you what combinations of rotation, reflection, translation, and dilation will make the W have the position, orientation, and size of the M.
The image (M) is the same size as the preimage (W), so no dilation is involved.
The up-down orientation of the image is opposite that of the preimage, so reflection across a horizontal line, or rotation 180° will be involved. Depending on the line of reflection or the center of rotation, translation to the final image position may be required.
The preimage is symmetrical about a vertical centerline, so translation left or right can also be accomplished by reflection about a suitable vertical line.
_____
If you have trouble visualizing this, it can help to cut the letter from a piece of paper and manipulate it to model rotation, reflection, or translation.
A salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $18. Option B is a commission rate of 4% on weekly sales. How much does he need to sell this week to earn the same amount with the two options?
Let S be the amount of money the salesperson needs to sell in a week to earn the same amount with the two options. The salesperson earns 40 * $18 = $<<40*18=720>>720 with Option A.
We can set up the following equation to represent the amount of money the salesperson earns with Option B:
0.04S = $720
Solving for S, we find that the salesperson needs to sell $720 / 0.04 = $<<720/0.04=18000>>18,000 to earn the same amount with Option B.

A parallelogram has vertices at (-5, -1), (-2, -1), (-3, -4), and (-6, -4). What is the approximate perimeter of the parallelogram? Round your answers to the nearest hundredth.
A. 9.16
B. 12 units
C. 12.32 units
D. 14
Answer:
12.32 units
Step-by-step explanation:
Use the distance formula to find the lengths between two points:
[tex]d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
the distance between (-2, -1) and (-5,-1) is
[tex]\sqrt{(-2-(-5))^2+(-1-(-1))^2}[/tex]
=[tex]\sqrt{3^2+0^2}[/tex]
=[tex]\sqrt{9}[/tex]
=3
the distance between (-2, -1) and (-3, -4) is
[tex]\sqrt{(-2-(-3))^2+(-1-(-4))^2}[/tex]
=[tex]\sqrt{1^2+3^2}[/tex]
=[tex]\sqrt{10}[/tex]
≈3.16
the distance between (-6, -4) and (-3, -4) is
[tex]\sqrt{(-6-(-3))^2+(-4-(-4))^2}[/tex]
=[tex]\sqrt{(-3)^2+0^2}[/tex]
=[tex]\sqrt{9}[/tex]
=3
the distance between (-6, -4) and (-5, -1) is
[tex]\sqrt{(-6-(-5))^2+(-4-(-1)^2}[/tex]
=[tex]\sqrt{(-1)^2+3^2}[/tex]
=[tex]\sqrt{10}[/tex]
≈3.16
Now, add all the sides:
3+3.16+3+3.16=12.32 units
Note: A property of a parallelogram is that it has two pairs of congruent sides, so for this problem, you could solve for 2 different sides, double them, then add and you will get the same thing.

0.01 is not the way of expressing the relationship because it does not represent the correct ratio between 10 square and 100 square
What is ratio ?A ratio tells the relationship between two or more quantities by comparing their relative sizes.It is typically written as two or more numbers separated by a colon (:), such as 2:4, or expressed as a fraction, such as 2/4. The numbers in a ratio represent the relative amounts of the quantities being compared. A ratio can be used to compare any type of quantity, such as length, weight, or time.
A) 10 square is 1/10th of the area of 100 square. It can be represented as a fraction, where the numerator is the area of the smaller square (10) and the denominator is the area of the larger square (100). The fraction would be 1/10.
B) Another way of expressing the relationship is as a percentage, where the smaller area (10) is divided by the larger area (100), and the result is multiplied by 100 to get the percentage. So 10 square is 10% of 100 square.

An object is moving at a speed of 3 yards per month. Express this speed in centimeters per day.
The speed of the object is 9.14 cm per day.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
Given that, An object is moving at a speed of 3 yards per month. we are asked to express this speed in centimeters per day.
For this, we will have to convert the units,
1 yard = 91.44 cm
3 yards = 91.44 × 3 = 274.32 cm
Therefore, we can say the object is moving 274.32 cm per month
Now,
If it moves 274.32 cm in one month,
Therefore, in day, it will move = 274.32 / 30 [1 month = 30 days]
= 9.144
Hence, the speed of the object is 9.14 cm per day.

What is the inverse of 7 5?
The multiplicative inverse of 7/5 is 5/7 using the formula of multiplicative inverse like (x)^-1 which equals to 1/x.
let's try to learn what is multiplicative inverse.
1/N or [tex]N^-1[/tex] is used to denote a number's multiplicative inverse, such as the number N. From the Latin word "reciprocus," it is also known as reciprocal. Inverse refers to something that is the opposite. The acquired reciprocal of a number is such that its value equals identity 1 when multiplied by the original number. In other terms, it is a technique for producing identity 1 by diluting a number by itself, as in N/N = 1.
One is obtained when a number is multiplied by its own multiplicative inverse.
When a number is multiplied by its original number, the multiplicative inverse of that number, or x^-1, produces a value equal to 1. The multiplicative inverse of 2, for instance, is 2^-1 since it fulfils the formula: 2 x (2^-1) = 2 x (1/2) = 1.It is also known as a number's reciprocal.
Multiplicative inverse of 7/5 is (7/5)^-1 = 1/(7/5) = 5/7.
