The total volume of the 21 bowling balls is 6048π cubic inches.
We have,
To find the total volume of the 21 bowling balls, we first need to calculate the volume of a single ball and then multiply it by the number of balls.
The volume of a sphere can be calculated using the formula:
V = (4/3) x π x r³
where V is the volume and r is the radius of the sphere.
Given that the diameter of the bowling ball is 12 inches, the radius can be calculated as half of the diameter:
r = 12/2 = 6 inches
Now we can calculate the volume of a single ball:
V_ball = (4/3) x π x (6³) = (4/3) x π x 216 = 288π cubic inches
Since there are 21 balls, we can calculate the total volume by multiplying the volume of a single ball by the number of balls:
Total volume = 21 x 288π = 6048π cubic inches
Thus,
The total volume of the 21 bowling balls is 6048π cubic inches.

Point A is translated 2 units up and 5 units to the right, where it now overlaps point B(3,-1)
Point A will have coordinates (-2, -3), which overlaps with the coordinates of Point B (3, -1).
To determine the new coordinates of Point A after the translation, we can start with the coordinates of Point B and apply the inverse translation.
Given that Point B has the coordinates (3, -1), we know that Point A after translation will have the same coordinates. We need to determine the inverse translation that will bring Point B back to its original position, and then apply that inverse translation to Point B.
The inverse translation of moving 2 units up and 5 units to the right is moving 2 units down and 5 units to the left. Therefore, we need to subtract 2 from the y-coordinate and subtract 5 from the x-coordinate of Point B.
Applying this inverse translation to Point B (3, -1), we have:
New x-coordinate of Point A = 3 - 5 = -2
New y-coordinate of Point A = -1 - 2 = -3

We have,
The number of different homework sets Mrs. Brown could assign can be calculated using the combination formula.
In this case, she wants to choose 8 problems out of 11 available problems. The formula for combinations is given by:
C(n, r) = n! / (r! * (n - r)!)
Where n is the total number of items to choose from and r is the number of items to be chosen.
Using this formula:
C(11, 8) = 11! / (8! x (11 - 8)!)
C(11, 8) = 11! / (8! x 3!)
Simplifying the factorial expressions:
C(11, 8) = (11 x 10 x 9 x 8!) / (8! x 3 x 2 x 1)
The factorial terms cancel out:
C(11, 8) = (11 x 10 x 9) / (3 x 2 x 1)
C(11, 8) = 165

There are 52 students taking none of the three languages.
There are 14 students taking both Arabic and Bulgarian. Of these, some may also take Chinese. We can find out how many by subtracting the students taking only Arabic or only Bulgarian from the total number of students taking Arabic and Bulgarian (14 + 15 + 19 = 48). So, 48 - 30 - 19 = 15 students are taking both Arabic and Bulgarian, and some of them may also take Chinese.
Next, we can subtract the students taking only Arabic, only Bulgarian, and only Chinese from the total number of students taking each language to find out how many students are taking all three languages.
From the students taking Arabic, we subtract the 15 students taking only Arabic: 30 - 15 = 15 students who may also be taking Bulgarian and Chinese.
From the students taking Bulgarian, we subtract the 19 students taking only Bulgarian: 36 - 19 = 17 students who may be taking Arabic and Chinese.
From the students taking Chinese, we subtract the 19 students taking only Chinese: 35 - 19 = 16 students who may be taking Arabic and Bulgarian.
So, there are 15 + 17 + 16 = 48 students who are taking some combination of the three languages.
Finally, to find out how many students are taking all three languages, we subtract the students taking only two of the languages from the total number of students taking some combination of the three languages (48 - (15 + 19 + 17) = 48 - 51 = -3). This means there are no students taking all three languages.
To find out how many students are taking none of the three languages, we subtract the total number of students taking some combination of the three languages from the total number of students at the school (100 - 48 = 52).
Hence, there are 52 students taking none of the three languages.

How many tiles can fit in a rectangular floor with length 14 ft and width 6 ft if the the square tiles has an edge of 3/4 ft.
A rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.
To determine how many square tiles can fit in a rectangular floor, we need to calculate the total number of tiles that can fit both horizontally and vertically.
Given:
Length of the rectangular floor = 14 ft
Width of the rectangular floor = 6 ft
Edge length of square tile = 3/4 ft
First, let's calculate the number of tiles that can fit horizontally:
Length of the rectangular floor / Edge length of square tile = 14 ft / (3/4 ft) = 14 ft × (4/3 ft) = 56/3 ft
Since we want a whole number of tiles, we need to round down or take the floor value:
Number of tiles horizontally = floor(56/3) = 18 tiles
Next, let's calculate the number of tiles that can fit vertically:
Width of the rectangular floor / Edge length of square tile = 6 ft / (3/4 ft) = 6 ft × (4/3 ft) = 24/3 ft
Again, we round down or take the floor value:
Number of tiles vertically = floor(24/3) = 8 tiles
To find the total number of tiles, we multiply the number of tiles horizontally by the number of tiles vertically:
Total number of tiles = Number of tiles horizontally × Number of tiles vertically = 18 tiles × 8 tiles = 144 tiles
Therefore, in a rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

John, Rick, and Molli can paint a room working together in 5 hours. Alone, Molli can paint the room in 14 hours. If Rick works alone, he can paint the room in 10 hours. Write an equation comparing the group rate to the sum of the individual rates. Then find how long it will take John to paint the room if working alone.
It will take John approximately 2.69 hours to paint the room alone.
Let's denote the individual rates of John, Rick, and Molli as J, R, and M, respectively. We are given the following information:
John, Rick, and Molli can paint the room together in 5 hours.
Molli alone can paint the room in 14 hours.
Rick alone can paint the room in 10 hours.
To find the equation comparing the group rate to the sum of the individual rates, we can use the concept of work done. The amount of work required to paint the room is the same, regardless of who is doing the work.
The equation can be expressed as:
1/5 = 1/J + 1/R + 1/M
Now, let's substitute the given information into the equation. We know that:
M = 14 (since Molli can paint the room alone in 14 hours)
R = 10 (since Rick can paint the room alone in 10 hours)
Substituting these values, the equation becomes:
1/5 = 1/J + 1/10 + 1/14
To solve for J, we can find the least common denominator (LCD) of 10 and 14, which is 70:
14J + 7J + 5J = 70
26J = 70
J = 70/26
J ≈ 2.69
Therefore, it will take John approximately 2.69 hours to paint the room alone.

arrange the numbers: -7 -5 -3 3 -1 1 into three pairs with the same total
The numbers -7, -5, -3, 3, -1, and 1 can be arranged into three pairs with the same total (-7, 7), (-5, 5), (-3, 3), (-1, 1).
To arrange the numbers -7, -5, -3, 3, -1, and 1 into three pairs with the same total, we need to find a combination of pairs that will give us the same sum for each pair.
Let's start by examining the numbers:
-7, -5, -3, 3, -1, 1
To find pairs with the same total, we can start by pairing the numbers with their additive inverses (numbers that sum to zero). In this case, -7 and 7, -5 and 5, -3 and 3 can be paired up. This leaves us with -1 and 1.
We have three pairs now: (-7, 7), (-5, 5), (-3, 3). However, we still have -1 and 1 remaining. To make the sum of the pairs equal, we can pair -1 with 7 and 1 with -5.
The three pairs with the same total are:
(-7, 7), (-5, 5), (-3, 3), (-1, 1).
Each pair sums up to zero, resulting in the same total for each pair. For example, (-7 + 7 = 0), (-5 + 5 = 0), and so on.
Therefore, the numbers -7, -5, -3, 3, -1, and 1 can be arranged into three pairs with the same total:
(-7, 7), (-5, 5), (-3, 3), (-1, 1).

Find the mystery number from the following clues
It is a 2-digit number
It is a factor of 48
It is a multiple of 6
The sum of the digits is 3
Based on the given clues, the mystery number is 12.
Let's analyze the clues given to find the mystery number:
It is a 2-digit number: This means the number is greater than or equal to 10 and less than 100.
It is a factor of 48: The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
It is a multiple of 6: The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and so on.
The sum of the digits is 3: From the clues, we know that the mystery number is a 2-digit number, so let's consider the possible numbers where the sum of the digits is 3:
12 (1 + 2 = 3)
21 (2 + 1 = 3)
Now let's check which of these numbers satisfy the first three clues:
12: This number is a factor of 48 (48 ÷ 12 = 4) and it is a multiple of 6 (12 ÷ 6 = 2). The sum of the digits is 3. Therefore, 12 satisfies all the clues.
21: This number is not a factor of 48 (48 ÷ 21 ≈ 2.29), so it doesn't satisfy the second clue.
Based on the given clues, the mystery number is 12.

What is the meaning of "A function f is one-to-one"?
A function f is said to be one-to-one, or injective, if it has the property that for any two different inputs, it produces two different outputs.
What is the meaning of "A function f is one-to-one"?More formally, a function f: X -> Y is one-to-one (or injective) if for every x1, x2 in X, if x1 ≠ x2 then f(x1) ≠ f(x2).
This means that no two different elements of the domain X map to the same element of the codomain Y. If you were to draw a horizontal line through any point on the graph of a one-to-one function in the Cartesian plane, that line would intersect the graph at most one time. This is known as the "horizontal line test" for one-to-one functions.

Uncle Joe made chocolate chip cookies. Michael ate 50% right away. Robert ate 50% of what was left. fourteen cookies remain. How many cookies did Uncle Joe make?
Answer:
50% ate uncle joe and 50% ate robert so, uncle joe make 14 cookies
Answer:
1. Michael ate 50% of the cookies, so the remaining cookies are 50% of the total. Let's denote the total number of cookies as T. So, after Michael ate his share, 0.5 x T cookies remained.
2. Robert then ate 50% of what was left, leaving only 50% of the cookies that were left after Michael ate. So, after Robert ate his share, 0.5 x 0.5 x T = 0.25 x T cookies remained.
3. We know that 14 cookies remained after Robert ate his share.
So, we can set up the equation 0.25 x T = 14 and solve for T:
T = 14/0.25 = 56
So, Uncle Joe made 56 chocolate chip cookies.

Susan has two solutions that contain alcohol. She uses 100 millileters less of solution a than solution b. Solution A HAS 13% ALCOHOL AND SOLUTION b is 10% alcohol. How many milliliters of solution b is used if the resulting mixture has 102 milliliters of pure alcohol
Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.
Let's set up the equation based on the given information.
Let x represent the amount of solution b in milliliters.
Since Susan uses 100 milliliters less of solution a than solution b, the amount of solution a is (x - 100) milliliters.
We know that solution a has a concentration of 13% alcohol, which means that for every 100 milliliters, it contains 13 milliliters of alcohol.
Similarly, solution b has a concentration of 10% alcohol, which means that for every 100 milliliters, it contains 10 milliliters of alcohol.
Given that the resulting mixture has 102 milliliters of pure alcohol, we can set up the equation:
0.13(x - 100) + 0.1x = 102
Simplifying the equation, we have:
0.13x - 13 + 0.1x = 102
0.23x - 13 = 102
0.23x = 115
x = 115 / 0.23
x = 500
Therefore, Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.

Is the relationship linear, exponential, or neither?
Based on the given data, the relationship appears to be exponential.
To determine if the relationship between the given values is linear, exponential, or neither, we can examine the pattern in the data.
If the relationship is linear, we would expect the values of y to increase or decrease at a constant rate as the values of x increase. In other words, there would be a constant slope between the points.
If the relationship is exponential, we would expect the values of y to change by a constant factor as the values of x increase. In this case, the relationship would exhibit exponential growth or decay.
Looking at the given values of x and y, we can observe the following differences between consecutive x-values: 7, 9, 9, 9. These differences are not constant, indicating that the relationship is not linear.
To determine if the relationship is exponential, we can examine the ratios between consecutive y-values: 5/10 = 0.5, 10/20 = 0.5, 20/40 = 0.5. These ratios are constant, suggesting that the relationship may be exponential with a common ratio of 0.5.

} One number is 8 times another. When the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number. What are the numbers?
The numbers are 1 and 8.
We have,
Let's assume the lesser number as "x" and the greater number as "8x".
According to the given information, when the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number:
8x - x = 5x + 2
Simplifying the expression:
7x = 5x + 2
Subtracting 5x from both sides:
2x = 2
Dividing both sides by 2:
x = 1
So, the lesser number is 1 and the greater number is 8 times that, which is 8.
Therefore,
The numbers are 1 and 8.

What is a translation?In Mathematics and Geometry, the translation of a graph to the right simply means a digit would be added to the numerical value on the x-coordinate of the pre-image:
g(x) = f(x - N)
Conversely, the translation of a graph downward simply means a digit would be subtracted from the numerical value on the y-coordinate (y-axis) of the pre-image:
g(x) = f(x) + N
Since the parent function y = ∣x∣ was translated 4 units to the right and 9 units down in order to produce the graph of the image, we have:
y = ∣x - 4∣ - 9

A) Two equations are,
S = 18 + 4t
L = 30 + 3t
Where, "t" represents the number of weeks that have passed.
B) It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.
C) when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.
Part A:
For a system of equations to represent the number of rocks in each person's collection.
Let "S" be the number of rocks in Samuel's collection and "L" be the number of rocks in Lewis's collection.
Hence, We can represent the situation as follows:
Equation 1:
S = 18 + 4t
Equation 2:
L = 30 + 3t
Where, "t" represents the number of weeks that have passed.
Part B:
To find out how many weeks it will take for Samuel and Lewis to have the same number of rocks in their collections, we need to set Equation 1 equal to Equation 2 and solve for "t".
This gives us the following:
S = L
18 + 4t = 30 + 3t
1t = 12
t = 12 weeks
Hence, It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.
Part C:
For number of rocks Samuel and Lewis will have when the amount of rocks in their collection is equal, we can substitute the value of "t" that we found in Part B into either Equation 1 or Equation 2.
Hence, substituting "t = 12" into Equation 1 gives,
S = 18 + 4(12)
S = 18 + 48
S = 66 rocks
Therefore, when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.
