What is a set?
Sets are represented as a collection of well-defined objects or elements and it does not change from person to person. A set is symbolised by a capital letter. The number of items in the finite set is known as the cardinal number of a set.
We are given two sets as S = {r, e, l, a, x} and T = {i, t, s, o, k, a, y}.
Now,
n (S) = 5
This is because there are 5 elements in this set.
n (T) = 7
This is because there are 7 elements in this set.
S ∪ T = {r, e, l, a, x, i, t, s, o, k, y}
n (∪) = 11
This is because there are 11 distinct elements in the sets.
S ∩ T = {a}
n (∩) = 1
This is because there is only 1 element common in the sets.
Hence, the required solution has been obtained.

Roselli's Machine Manufacturing Co reported its sales as R120 000, a gross profit of R50 000, and current liabilities of R25 000. If the current ratio is 2,5 and the quick ratio is 1,75, what is the inventory turnover for the company?
Answer:
Step-by-step explanation:
To find the inventory turnover for Roselli's Machine Manufacturing Co, we need to use the formula:
Inventory turnover = Cost of goods sold / Average inventory
First, we need to find the cost of goods sold (COGS):
COGS = Sales - Gross profit
COGS = R120 000 - R50 000
COGS = R70 000
Next, we need to find the average inventory. We can use the quick ratio formula to find the current assets:
Quick ratio = (Current assets - Inventory) / Current liabilities
Rearranging the formula to solve for inventory, we get:
Inventory = Current assets - (Quick ratio x Current liabilities)
Plugging in the values we know, we get:
1.75 = (Current assets - Inventory) / R25 000
Current assets - Inventory = 1.75 x R25 000
Current assets - Inventory = R43 750
Inventory = Current assets - R43 750
Since the current ratio is 2.5, we know that:
Current assets / Current liabilities = 2.5
Solving for current assets, we get:
Current assets = 2.5 x R25 000
Current assets = R62 500
Substituting the values we found for inventory and COGS into the inventory turnover formula, we get:
Inventory turnover = COGS / Average inventory
Inventory turnover = R70 000 / [(R62 500 - R43 750) / 2]
Inventory turnover = R70 000 / (R18 750 / 2)
Inventory turnover = R70 000 / R9 375
Inventory turnover = 7.47
Therefore, the inventory turnover for Roselli's Machine Manufacturing Co is 7.47.

What does perpendicular bisector mean?
A line that bisects another line segment into two equal-sized segments by crossing it perpendicularly might be said to be a perpendicular bisector. The midpoint of a line segment is traversed by a perpendicular bisector. A ruler and a compass are needed to build it. The line segment that is being divided is bisected at an angle of 90° on both sides.
What use serve perpendicular bisectors?
A line that cuts through the junction of two adjacent line segments at a right angle is known as a perpendicular bisector. With this in mind, we may state that a perpendicular bisector always splits a line segment in its middle. The word "bisect" itself refers to an even or uniform division.

Which expressions can be used to find each angle measure of a regular polygon with 28 sides? Select all that apply.
The correct answer is the third option: (28 - 2) x 180 / 28.
A regular polygon is what?An -sided polygon with regular sides that are all the same length and symmetrically arranged around a common centre is known as a regular polygon (i.e., the polygon is both equiangular and equilateral).
Every side of a regular polygon with 28 sides is the same length, and every interior angle is the same size.
The formula: gives the sum of the internal angles of a polygon with n sides.
Interior angle total equals (n - 2) x 180 degrees.
Each interior angle of a regular polygon has the same measure, thus we can calculate each interior angle's size by dividing the total of its internal angles by the number of sides. For a regular polygon with 28 sides, the expression to get each angle's measure is as follows:
(28 - 2) x 180 / 28
Simplifying the phrase:
(26 x 180) / 28
For a regular polygon with 28 sides, the shortened expression that may be used to determine each angle measure is:
4680/28
Which is further condensed to:
105*(4/7)
Hence, the appropriate phrase is:
(28 - 2) x 180 / 28 = 4680/28 = 105*(4/7)
As a result, the third option—(28 - 2) x 180 / 28—is the proper response.

Given ABC shown in the graph below, XYZ is found according to the following combined transformation function.
Look at both photos below to help answer the question.
The coordinates of triangle XYZ are X(-2,-2), Y(2,4), and Z(-4,8).
Describe Transformation?In mathematics, a transformation refers to a change or modification of an object's position, shape, size, or orientation in a coordinate plane or space. Transformations can be described as functions that map the points or vertices of an object to new positions in the plane or space.
Common transformations include:
Translation: a transformation that moves an object without changing its size, shape, or orientation. Translation involves shifting all points of the object by the same distance in the same direction.
Rotation: a transformation that turns an object about a fixed point or axis by a certain angle. Rotation preserves the size and shape of the object, but changes its orientation.
Scaling: a transformation that changes the size of an object by multiplying the coordinates of each point by a fixed factor. Scaling can either enlarge or reduce an object.
Since the transformation function is not provided, I'll assume that D2(ABC) means dilating the triangle ABC with center at the origin and a scale factor of 2.
To find the coordinates of the new triangle XYZ, we can apply the dilation transformation to each vertex of the original triangle:
For vertex A(-1,-1), we multiply its coordinates by the scale factor 2, giving us point X(-2,-2).
For vertex B(1,2), we multiply its coordinates by the scale factor 2, giving us point Y(2,4).
For vertex C(-2,4), we multiply its coordinates by the scale factor 2, giving us point Z(-4,8).

Form. Two different methods need to be shown.
You can choose between Area Model, Distributive
Property and FOIL.
(3x − 4)(2x − 1)
Answer:
Method 1: Distributive Property
To multiply (3x - 4) and (2x - 1), we can use the distributive property:
(3x - 4)(2x - 1) = 3x(2x) + 3x(-1) - 4(2x) - 4(-1)
= 6x^2 - 3x - 8x + 4
= 6x^2 - 11x + 4
Therefore, the final answer in standard form is 6x^2 - 11x + 4.
Method 2: FOIL
To multiply (3x - 4) and (2x - 1), we can use the FOIL method:
(3x - 4)(2x - 1) = 3x(2x) + 3x(-1) - 4(2x) - 4(-1)
= 6x^2 - 3x - 8x + 4
= 6x^2 - 11x + 4
Therefore, the final answer in standard form is 6x^2 - 11x + 4.

what are the x- and y- coordinates of point P on the directed line segment from A to B such that P is 2/3 the length of the line segment from A to B? x= [m/m+n](x2 -x1) +x1 y = [m/m+n](y2 - y1) +y1
Where m is the distance from A to P and n is the distance from P to B.
What is Length?Length is a measure of distance or size. It is the measurement of the longest dimension of an object, such as a line, segment, or plane. It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches. Length is also used to measure the amount of time it takes for something to occur, such as the length of a movie or a song.
Therefore, if the coordinates of A are (x1, y1) and the coordinates of B are (x2, y2), the x- and y- coordinates of point P would be:
x= [2/3(x2 -x1) +x1
y = [2/3](y2 - y1) +y1
This equation can be used to calculate the coordinates of any point P on a directed line segment from A to B such that P is a fraction of the length of the line segment from A to B. By setting the fraction equal to 2/3, we can calculate the coordinates of point P that is 2/3 the length of the line segment from A to B. This can be useful in a variety of applications, such as computer graphics, game design, and engineering. For example, this equation could be used to calculate the coordinates of a point on a line segment that is an exact distance from the two endpoints, or to calculate the coordinates of a point that is a certain percentage of the distance between the two endpoints.

It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches.
Given the coordinates of the points A, B and P, we can calculate the x- and y- coordinates of point P such that it is 2/3 the length of the line segment from A to B.
To do this, we need to use the following formula: x = [m/m+n](x2 -x1) +x1, y = [m/m+n](y2 - y1) +y1, where m is 2/3, n is 1/3, x1 and y1 are the x- and y-coordinates of point A, and x2 and y2 are the x- and y-coordinates of point B.
In this case, m = 2/3, n = 1/3, x1 = 2, y1 = -1, x2 = 4, y2 = -3.
Therefore, plugging these values into the formula we get:
x = [2/3](4 -2) +2 = 4
y = [2/3](-3 - (-1)) + (-1) = -2

Pls help Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units? What is the area when x = 3?
Answer:
Step-by-step explanation:
The area A of a rectangle is given by the formula:
A = length × width
In this case, the length is 2x - 4 units and the width is x + 1 units. So the function that models the area of the rectangle is:
A(x) = (2x - 4)(x + 1)
Expanding this expression, we get:
A(x) = 2x^2 - 2x - 4x + 4
A(x) = 2x^2 - 6x + 4
To find the area when x = 3, we can substitute x = 3 into the function:
A(3) = 2(3)^2 - 6(3) + 4
A(3) = 18 - 18 + 4
A(3) = 4
Therefore, when x = 3, the area of the rectangle is 4 square units.
a telephone company makes up its monthly bills as follows: a fixed charge of 800 naira plus a charge proportional to the number of units of call on the telephone. if it charges 2 naira per unit of call, calculate the total charge on
a) 80units
b) 150units
c) 782 units
The total charge for 782 units of call is 2364 naira.
What is a total charge?
Total Charges refers to all payments made by the Customer and all amounts due under the Contract for products and services that the Council has actually provided, regardless of whether the Customer has received an invoice.
We can use the formula:
total charge = fixed charge + charge per unit x number of units
a) For 80 units of call:
total charge = 800 + 2 x 80
total charge = 800 + 160
total charge = 960 naira
Therefore, the total charge for 80 units of call is 960 naira.
b) For 150 units of call:
total charge = 800 + 2 x 150
total charge = 800 + 300
total charge = 1100 naira
Therefore, the total charge for 150 units of call is 1100 naira.
c) For 782 units of call:
total charge = 800 + 2 x 782
total charge = 800 + 1564
total charge = 2364 naira
Therefore, the total charge for 782 units of call is 2364 naira.

The perimeter of a rectangular garden is 30 ft. The length is 3 ft more than the width. Find the length and the width of the garden.
Step-by-step explanation:
the perimeter of a rectangle is
2×length + 2×width
in our case
length = width + 3
and
2×length + 2×width = 30
using the first equation in the second :
2×(width + 3) + 2×width = 30
width + 3 + width = 15
2×width + 3 = 15
2×width = 12
width = 12/2 = 6 ft
length = width + 3 = 6 + 3 = 9 ft

By using the Pythagorean theorem we know that the given triangle is not a right triangle.
What is the Pythagorean theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.
According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Pythagorean triples consist of the three positive numbers a, b, and c, where a2+b2 = c2.
The symbols for these triples are (a,b,c). Here, a represents the right-angled triangle's hypotenuse, b its base, and c its perpendicular.
The smallest and most well-known triplets are (3,4,5).
So, we have the values already,
Now, calculate as follows:
3² + 4² = 6²
9 + 16 = 36
25 ≠ 36
Hence, the given triangle is not a right triangle.
Therefore, by using the Pythagorean theorem we know that the given triangle is not a right triangle.

Whats the the sum of x and 2
The sum of x and 2 is equal to x + 2.
What is value?Value in math is the numerical representation of a quantity or expression. It can also be defined as an amount or a numerical representation of a quantity that is assigned to a variable or a constant in a mathematical expression. Value can be expressed in various forms, such as decimal, fraction, and scientific notation. Value is also used to calculate the result of an equation or a problem. Value is a fundamental concept in mathematics, and it is used to measure and compare different quantities.
This equation can be used to calculate the sum of any two numbers, x and 2. For example, if x is equal to 5, then the sum of x and 2 is equal to 5 + 2, which is equal to 7. Similarly, if x is equal to 10, then the sum of x and 2 is equal to 10 + 2, which is equal to 12. Therefore, the sum of x and 2 depends on the value of x.
