What is system of inequalities ?
A system of inequalities is a set of two or more inequalities with one or more variables. The solution to a system of inequalities is the set of all possible values of the variables that satisfy all the inequalities in the system simultaneously. In other words, it is the intersection of the solution sets of each individual inequality in the system.
According to the question:
The two correct statements are B and D.
B is true because trailing zeros after a decimal point do not change the value of a number, so 4.5 is equal to 4.50.
D is true because 1.51 is greater than 1.15, as the digits to the right of the decimal point represent fractions of a whole number, so 0.51 is greater than 0.15.
A is false because 1.01 is greater than 0.99.
C is false because 3.5 is greater than 3.39.
E is false because 2.09 is not equal to 2.9.

Let's name the quantity of housework the youngster performed "x".
The total earnings can be expressed by the equation below, where the child earns an additional $12 if they finish all the chores on the chore list:
Total income = 2x plus 12
We are informed that the child accomplished all of the chores on the list for the previous month and earned $44. We may set this equal to 44 and find x by using the equation above:
2x + 12 = 44
2x = 32
x = 16
The kid finished 16 housework tasks last month.
Now that we know which of the following is true:
A) The youngster finished ten domestic duties.
This is untrue, since we determined that the child accomplished 16 domestic duties.

Answers
Brad needs to score between 72 and 79 on the fourth test in order to get a C for the semester.
To explain why this is so, we need to first understand how the grade for the semester is calculated.Since the final course grade depends entirely on the average of four equally weighted 100-point tests, this means that each test will count for 25% of Brad’s final grade. Therefore, Brad needs to get an average score of 70-79 (inclusive) on the four tests combined in order to get a C for the semester.
In order to calculate what range of scores Brad needs to get on the fourth test in order to get a C for the semester, we need to look at the scores he has already obtained on the first three tests. Brad has scored 87, 89 and 78 on the first three tests. This gives him a total score of 254 (87+89+78=254). This means that Brad needs to get a score of between 70 and 79 on the fourth test in order to reach a total score of between 280-309 (inclusive), which will result in an average score of between 70-79 (inclusive), and give Brad a C for the semester.

what is unitary method ?Mathematicians use the unitary method, also referred to as the "single unit technique," to answer problems involving proportional relationships between two or more quantities. The unitary technique entails determining the value of a single unit or quantity and using that value to calculate the values of other quantities in relation to that unit or quantity. Problems requiring ratios, proportions, percentages, and other related ideas can be solved using this approach.
given
Shay's age will be denoted by the letter S, and her sister's age will be referred to as "Sister".
The first claim informs us of the following:
Sibling = 2S – 7
And based on the second assertion, we can infer that:
Sibling + S = 80
The result of putting the first equation into the second equation is:
S + (2S - 7) = 80
When we simplify this solution, we obtain:
3S - 7 = 80
7 added to both edges gives us:
3S = 87
When we multiply both parts by 3, we get:
S = 29
Since Shay's sibling is 7 years younger than twice her age, Shay is therefore 29 years old.

A student solved the equation extraneous? Explain. 5/x-4 = x/x-4 and got 4 and 5 as solutions. Which, if either, of these is extraneous? Explain.
Answers
Therefore , the solution of the given problem of equation comes out to be x = 5 is a correct answer to the problem.
What is equation?Complex algorithms frequently employ variable words to demonstrate coherence between two opposing assertions. Equations are academic expressions that are used to demonstrate the equality of different academic figures. In this instance, normalization results in a + 7 rather than a separate algorithm who divides 12 onto two separate components and is able to evaluate data obtained from x + 7.
Here,
We can begin by making the provided equation simpler:
=> 5/(x - 4) = x/(x - 4)
=> 5 = x
Consequently, x = 5 is the answer to the problem.
The result of adding x = 4 to the initial equation is:
=> 5/(4 - 4) = 4/(4 - 4)
That amounts to:
=> 5/0 = 4/0
However, since division by zero is undefinable, the answer x = 4 is superfluous and does not satisfy the equation.
The result of the initial equation with x = 5 is:
=> 5/(5 - 4) = 5/(5 - 4)
That amounts to:
=> 5/1 = 5/1
As a result, x = 5 is a correct answer to the problem.
In conclusion, only one of the solutions -x = 5 is correct, and the other
-x = 4 is unnecessary because it results in a divide by zero.

a cable tv receiving dish is in the shape of a paraboloid of revolution. find the location of the receiver, which is placed at the focus, if the dish is 6 feet across at its opening and 2 feet deep.
Answers
the receiver is located at (0, 0, 2.25 feet) or (0, 0, 27 inches).To find the location of the receiver, we first need to determine the equation of the paraboloid.
The standard equation for a paraboloid of revolution with a vertical axis is:
z = [tex](x^2 + y^2)[/tex]/(4f)
Where:
z is the height at any point (x, y) on the paraboloid.
x and y are the horizontal coordinates of the point.
f is the focal length of the paraboloid, which is half the depth of the dish.
In this case, the dish is 6 feet across at its opening, so the diameter is 6 feet and the radius is 3 feet. Therefore, the maximum value of x and y is 3 feet. The depth of the dish is given as 2 feet.
Using these values, we can solve for the focal length:
2 = [tex](3^2 + 3^2)[/tex]/(4f)
2 = 18/(4f)
f = 18/8 = 9/4 = 2.25 feet
Now that we have the value of f, we can find the location of the receiver, which is placed at the focus of the paraboloid. The focus is located at (0, 0, f).
Therefore, the receiver is located at (0, 0, 2.25 feet) or (0, 0, 27 inches).

The sum of two numbers is 25, and the larger is 3 less than three times the smaller. What is the number?
Answers
The smaller number is 5.5 and the larger number is 15.5.
Let's start by assigning variables to the two unknown numbers. Let x be the smaller number and y be the larger number.
From the problem statement, we know that:
x + y = 25 (the sum of the two numbers is 25)
y = 3x - 3 (the larger number is 3 less than three times the smaller)
We can use the second equation to solve for y in terms of x, by adding 3 to both sides:
y + 3 = 3x
Then, we can substitute this expression for y into the first equation:
x + (y + 3) = 25
Substituting y + 3 with 3x, we get:
x + 3x = 22
Combining like terms, we get:
4x = 22
Finally, we solve for x by dividing both sides by 4:
x = 5.5
Now that we know x, we can use the equation y = 3x - 3 to find y:
y = 3(5.5) - 3 = 15.5

Answers
The width of the rectangular prism box is 1.5 inches if the length of the box is 5 inches and the height of the box is 8 inches.
The volume of a rectangular prism = 60 cubic inches.
The length of the box = 5 inches
The height of the box = 8 inches
To calculate the width of the rectangular prism, we can use the formula for volume:
Volume = length * width * height
Mathematically,
V = l*w*h
60 = 5w * 8
w = 60 / (5 * 8)
w = 1.5 inches

Use the rational zeros theorem to find all the real zeros of the polynomial function. use the zeros to factor f over the real numbers. f(x)=x^3-5x^2-61x-55???
Answers
The polynomial function f(x) = x³ - 5x² - 61x - 55 has the following
Real zeros: x = -5, x = -1, and x = 11.
To find the rational zeros of a polynomial, we use the rational zeros theorem. We look at the factors of the leading coefficient and the factors of the constant coefficient.
The states that if a polynomial function is defined as P(x) = anxn + an-1xn-1 + ... + a1x + a0 with integers, then each rational zero of the polynomial can be expressed in the form p/q where p is a factor of a0 and q is a factor of an.
For example, if P(x) = 2x³ - 5x² + 3x + 6 then p can be any factor of 6 and q can be any factor of 2.
The factors of the leading coefficient, 1, and the factors of the constant coefficient, -55, are: ±1, ±5, ±11, ±55. So the possible rational zeros are: ±1, ±5, ±11, ±55, ±1/1, ±5/1, ±11/1, ±55/1, ±1/1, ±5/1, ±11/1, ±55/1.
Simplifying the results, we have that the potential rational zeros are: ±1, ±5, ±11, ±55, ±1, ±5, ±11, and ±55.
By testing each possible rational zero, we find that x = -5, x = -1, and x = 11 are the real zeros of f(x).
Hence, using synthetic division, we get:
(x + 5)(x + 1)(x - 11) = x³ - 5x² - 61x - 55
Thus, the function can be factored over the real numbers as
f(x) = (x + 5)(x + 1)(x - 11).

Help me find the surface area and the lateral area of this
Answers
The surface area οf the cylinder is 170π & the lateral area οf the cylinder is apprοximately 376.99 square centimetres.
What exactly is a cylinder?In geometry, a cylinder is one of the basic three-dimensional shapes with two distant parallel circular bases.
Tο find the surface area and lateral area οf the given shape, we need tο first identify the shape. Based οn the given image, it appears tο be a right circular cylinder.
The surface area οf a right circular cylinder is given by the fοrmula:
Surface Area = 2πr² + 2πrh
where r is the radius οf the base and h is the height οf the cylinder.
Frοm the image, we can see that the radius οf the cylinder is 5 cm and the height is 12 cm.
Consequently, the cylinder's surface area is as follows:
Surface Area = 2π(5)² + 2π(5)(12)
Surface Area = 2π(25) + 2π(60)
Surface Area = 50π + 120π
Surface Area = 170π
Sο, the surface area οf the cylinder is apprοximately 533.15 square centimetres.
The lateral area οf the cylinder is the area οf the curved surface, which is given by: Lateral Area = 2πrh.
Substituting the values οf r and h, we get:
Lateral Area = 2π(5)(12)
Lateral Area = 120π
Sο, the lateral area οf the cylinder is apprοximately 376.99 square centimetres.

Mitchelle and Angela won R18000 in a competition and they decided share the money in the ratio 2:3how much will each get
Answers
Mitchelle will receive R7200 and Angela will receive R10800.
How to find the value of one part by dividing the total amount won by the total number of parts?
To determine how much Mitchelle and Angela will each receive in the ratio of 2:3, we need to first find the total number of parts in the ratio, which is 2 + 3 = 5.
Value of one part = R18000 ÷ 5 = R3600
Therefore, one part of the ratio 2:3 is equal to R3600.
How to find out how much Mitchelle and Angela will each receive?
we can multiply their respective parts by the value of one part:
• Mitchelle's share = 2 parts × R3600 per part = R7200
• Angela's share = 3 parts × R3600 per part = R10800
Therefore, Mitchelle will receive R7200 and Angela will receive R10800.

who in 1706 first gave the greek letter pi its current mathematical definition
Answers
The mathematician William Jones is credited with first using the Greek letter π
The mathematician William Jones is credited with first using the Greek letter π to represent the ratio of a circle's circumference to its diameter in a 1706 publication. He wrote, "there is no other more proper than Pi," and thus the symbol caught on among mathematicians. However, it's important to note that the concept of pi and its calculation had been around for thousands of years prior to Jones' use of the symbol.
Ancient Egyptian, Babylonian, and Indian mathematicians all had methods for approximating pi, and Archimedes famously used a geometric method to calculate it to a high degree of accuracy in the third century BCE.

An angle measures 62° more than the measure of its complementary angle. What is the measure of each angle?
Answers
one angle measures 76°, and
its complementary angle measures 90° - 76° = 14°.
Step by step explanation:
Two angles are complementary if the sum of their measures is 90°. Let x be the measure of one angle, then the measure of its complementary angle is 90° - x.
The problem states that one angle measures 62° more than the measure of its complementary angle, so we can set up the following equation:
x = (90° - x) + 62°
Simplifying and solving for x:
x = 90° - x + 62°
2x = 152°
x = 76°
Therefore, one angle measures 76°, and
its complementary angle measures 90° - 76° = 14°.
Which number correctly completes the ratio table?
2 8 13 14
16 Square 104 112
A. 64
B. 48
C. 40
D. 32
Answers
Using a constant factor, the number that completes the ratio table is calculated as: A. 64.
How to Solve Ratio Table?To complete the ratio table, we can observe that each number in the second row is obtained by multiplying the corresponding number in the first row by a constant factor of 8.
Thus, the ratio of the first row number to the second row number is 1:8.
This means that:
2 * 8 = 16
13 * 8 = 104
8 * 8 = 64.
Therefore, we can also get the correct number that completes the ratio table by multiplying 8 by 8, which is:
8 * 8 = 64.
So, the missing number in the ratio table is: A. 64.
