The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.
Both concepts are fundamental in arithmetic and algebraic calculations.
In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:
1. **Unknown Factor:**
- An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.
- In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.
- For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."
2. **Quotients:**
- "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.
- In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).
- For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.
- Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.

Step-by-step explanation:
9 of the students in Sarah's grade like to watch football and 12 like to watch figure skating. 7 students like to watch both football and figure skating. How many students like to watch football but not figure skating?
Answer:
Step-by-step explanation:
Total for football: 9 +7
Total for figure skating: 12 +7
NEW Total for football: 16
NEW Total for figure skating: 19
The question says that 9 people like football
The question says that 12 people like to watch figure skating
The question also says that 7 people like to watch both, and because of that, you should add 7 to both 9 and 12, but keep the new numbers separated from each other. So once we know the sum of 9 +7 is 16, and 12 + 7 is 19, we can subtract the two numbers, and get 3 as the answer. Because you are counting the number of times that you have to travel up or down to the other number, and so if you are on a set of stairs that go up to the 16 level and you are on the 14th level, you need to travel up 2 sets of stairs to get to level 16.
Hope that example helps and can help in the future with other problems!
Convert 37.45 to a fraction
Answer:
37 9/20
Step-by-step explanation:
Answer:
[tex]{ \bf{answer \: is \: { \underline{37 \frac{9}{20} }}}}[/tex]
Step-by-step explanation:
When converting to fraction, you must get to know about the place values.
3 » tens
7 » ones
.4 » tenth
5 » hundredth
since last place value is hundredth, fraction denominator must be 100
therefore:
[tex]37.45 = \frac{3745}{100} [/tex]
then you can reduce by 5:
[tex] = \frac{3745 \div 5}{100 \div 5} \\ \\ = \frac{749}{20} [/tex]
In mixed fraction:
[tex] = 37 \frac{9}{20} [/tex]

find the size of unknown angle
Answer:
Step-by-step explanation:
ΔAOC is an isosceles triangle as OC = OA ----> RADIUS
42 + 42 + ∠AOC = 180 {Angle sum property}
84 + ∠AOC = 180
∠AOC = 180 - 84
∠AOC = 96°
y = 96/2 {Central angle theorem}
y = 48° ------------(I)
∠B + ∠D = 180 {sum of opposite angles of Cyclic Quadrilateral}
x + y = 180
x + 48 = 180 {from (I) }
x = 180 - 48
x = 132°
Answer:
x = 132°
Step-by-step explanation:
ΔAOC is an isosceles triangle as OC = OA ----> RADIUS
42 + 42 + ∠AOC = 180 {Angle sum property}
84 + ∠AOC = 180
∠AOC = 180 - 84
∠AOC = 96°
y = 96/2 {Central angle theorem}
y = 48° ------------(I)
∠B + ∠D = 180 {sum of opposite angles of Cyclic Quadrilateral}
x + y = 180
x + 48 = 180 {from (I) }
x = 180 - 48

Find the equation of the line through (-7, -2) that is perpendicular to the line y = x/3+6.
Give your answer in the form y = mx + b.
Answer:
y = −3x − 23
Step-by-step explanation:
The equation of the line in the slope-intercept form is y= x/3 + 6.
The slope of the perpendicular line is negative inverse: m = −3.
So, the equation of the perpendicular line is y = −3x + a.
To find a, we use the fact that the line should pass through the given point:
−2 = (−3) ⋅ (−7) + a.
Thus, a = −23.
Therefore, the equation of the line is y = −3x − 23.
Answer: y =−3x − 23

If point P(2,-4) is reflected over the x-axis, determine the coordinates of the image.
(-2, -4)
(-4, 2)
(4, 2)
(2, 4)
Answer:
(2,4)
Step-by-step explanation:
the x values stays the same because you are reflecting over its axis. the 4 becomes positive
Step-by-step explanation:
Algebra Explanation: If something is reflected over the x axis, the x coordinate's sign will stay the same while the y coordinate sign will switch.
Using this info, the answer will be (2,4)
Geometric Explanation: Point P is in Quadrant 4. If we reflect a point about the x axis, it can only go to Quadrant 1. Quadrant 1 has a positive x and positive y. So this eliminates the first 2 options.
Reflecting across a line will align the pre image and current image with each other. This means the x coordinate and y coordinate will stay in the same place. So (2,4) is the answer.
What is the degree of rotation that takes quadrilateral FGHI to F'G'H'I?
Answer:
What is the degree of rotation that takes quadrilateral FGHI to F'G'H.
Step-by-step explanation:
The figure will have 180 degrees of rotation.
What is translation?The process of changing the location of the image on the coordinate system will be known as the translation.
The angle of rotation is a unit of measurement in mathematics that expresses the angle at which a figure is rotated about a given point, frequently the center of a circle.
Given that the figure FGHI is translated to become F'G'H'I. Each point of the given diagram must be changed from (x, y) to (z) when it is rotated 180 degrees around the origin, either clockwise or counterclockwise (-x, -y)
Here the point H of the figure changes from ( -4,5) to (4,-5). It shows that the degree of rotation of the figure is 180.
Therefore, the figure will have 180 degrees of rotation.

Substitute given information into given equation
b=2, c=-7/4
2-(-1/8) + - 7/4
Make 2 into 16/8 (by multiplying it by 8/8 To make denominator the same)
16/8 -(-1/8) + -7/4
17/8 (Because when negative and negative will make positive)
17/8+ -7/4
Make -7/4 into -14/8 (by multiplying it by 2/2 To make denominator the same)
17/8 -14/8 (Because negative and positive will make negative)
3/8 is the final answer

The histogram represents the distribution of lengths, in inches, of 25 catfish caught in a lake.
1. If possible, find the mean. If not possible, explain why not.
2. If possible, find the median. If not possible, explain why not.
3. Were any of the fish caught 12 inches long?
4. Were any of the fish caught 19 inches long?
An histogram provides a good visualization of data, however, the values of the data points are left out in an histogram
The correct responses are as follows;
1. The possible mean is given as follows;
Mean = ∑(fx)/(∑f)
Using the central values, we have;
Estimate of the Mean = (4.5×4 + 7.5×9 + 10.5×5 + 13.5×6 + 16.5×1)/(1 + 9+ 5+ 6+ 1) ≈ 10.7
2. The median is the middle value class
The total area of the histogram is given as follows
3 × (4 + 9 + 5 + 6 + 1) = 75
The middle value is located at half the total area = 75/2 = 37.5
The median class is the class of catfish with length 6 - 9 inches
3. There where 5 fishes caught that have lengths between 9 and 12 inches and there where 6 fishes caught that are 12 to 15 inches long
4. No, the longest fish caught was 18 inches long

A.)
Total Number of students = 60
Since each candidate passed in atleast one of English and Math ; the none of the students failed.
Percentage who passed :.
Mathematics only = 20%
English only = 40%
Since, no one failed ; percentage that passed both = 100% - (40+20)% = 40%
Number who passed Mathematics only :
20% × 60 = 12 students
Number that passed English only :
40% × 60 = 24 students.
Number that passed both = (40% × 60) = 24 students
Number that passed English = (Number that passed English only + Number that passed both) = 24 + 24 = 48
.Number that passed mathematics = (Number that passed Maths only + Number that passed both) = 12 + 24 = 36
2.)
Total daddy has = 50
Half given to mummy = 1/2 × 50 = 25
Amount given to houseboy = 10
Amount left = 50 - (25 + 10) = 15
Fraction of Amount left = 15/50 = 3/10
C.)
Length of cuboid = 12
Height = 8 cm
Volume of cuboid = 480
Width = w
Recall :
Volume = Length × width × height
480 = 12 × 8 × w
480 = 96w
w = 490 / 96
w = 5
Width of the cuboid = 5
The surface area of a cuboid : 2(lh + lw + hw)
