Using Composition of functions, the value of g(h(24)) = 1158.
What is meant by Composition of functions?A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.
The new function h is created by combining the two functions f and g, where h(x) = f(g(x)) for all x in g's domain where g(x) is in f's domain. Function composition is denoted by the notation h = f • g, also written as h(x) = (f • g)(x), which can be interpreted as "f of g of x."
Given,
g(x) = 2x + 4, h(x) = x² +1
Using composition of functions,
⇒ h(24) = 24² + 1
⇒ g(h(24)) = 2 (24² + 1) + 4
⇒ g(h(24)) = 2 × 577 + 4
⇒ g(h(24)) = 1158

4. Mariela purchases a used microwave for $50. She marks the price up 60%. If a 5.8% sales tax is also added, what is the final price of the microwave?
Mariela spends $50 on a used microwave. By 60%, she raises the price. When a 5.8% sales tax is additionally included, the ultimate cost is 20 in 60% and 47.1 in 5.8%.
How do you mark up 60%?Cost plus markup % multiplied by cost is the formula used to increase a product's markup percentage. Let's say you're utilising a markup of 60% and the item costs $75. multiplying by 60 percent $75. Now you have $45. For instance, the markup percentage would be 50% if the cost to produce your product was $50 and the selling price was $75: ($75 - $50) / $50 =.50 × 100=50%.
0.6 is 60 hundredths of a unit, thus write it as 0.60. 60% is equal to 60 hundredths. The decimal point can alternatively be shifted two places to the right to find the % equivalent. As a result, the markup equation is now: markup = 100 × (revenue - cost) / cost. Last but not least, use revenue = cost + cost × markup / 100 to determine the selling price.

Is every triangle 90 degrees?.
A triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 90 degrees.
No, a triangle is not always 90 degrees. In geometry, a triangle is a three-sided polygon with three angles. The sum of the angles in a triangle is always 180 degrees.
This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.
For example, if a triangle has angles of 90 degrees, 60 degrees, and 30 degrees, the sum of these angles is 180 degrees (90+60+30=180).
Therefore, In short, a triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 90 degrees.

What is the proportion?
A proportion is two ratios that have been set equal to each other; a proportion is an equation that can be solved. When I say that a proportion is two ratios that are equal to each other, I mean this in the sense of two fractions being equal to each other. For instance, 5/10 equals 1/2.
Given that 4/9 of the fans in a football match are men and 200 are women. We must determine the total number of spectators at the football game.
If 4/9 of the total spectators are men, the remaining 5/9 are women.
Let x be the total number of spectators.
Mathematically,
5/9 of x = 200
5/9 × x = 200
5x = 1800
X = 360
As a result, the total number of spectators is 360.
The number of male spectators may also be calculated.
Males + Females = Total number of spectators
360 = Males + 200
Males = 160
Therefore, 4/9 of the spectators in a football match are males. If 200 of them are females, then the total number of spectators is 360.

Why is addition commutative and subtraction is not?.
Addition is commutative because the order in which two numbers are added does not affect the result.
Commutative property is applicable only for addition and multiplication processes. Thus, it means we can change the position or swap the numbers when adding or multiplying any two numbers.
Addition is commutative because the order in which two numbers are added does not affect the result. For example, 1 + 2 = 2 + 1 = 3. In contrast, subtraction is not commutative because the order in which two numbers are subtracted does affect the result. For example, 1 - 2 = -1, but 2 - 1 = 1. The operation is different when the order of the numbers are changed.

The probability that you win first prize and your friend wins second
prize is option D: 13/2730.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
Total number of prizes awarded = 3
Number of people entering the drawing competition = 15
Number of ways to award the prize = 2730
Out of the 3 prizes the first and the second is needed.
So, the prize for the first and the second positions are fixed and there is no need to consider the remaining 13 people to win the prize.
Hence the remaining number of people who can win the 3rd prize = 13
The number of ways one of them wins the 3rd prize = 13
The total number of ways = 2730

A claim is a statement or assertion that is made about a particular topic or issue. In this case, the statement is being made by "doctors" and is being presented as evidence of a causal relationship between lack of sleep and negative health outcomes. The statement is not an argument, which would include reasoning or logic to support the claim, nor is it a testimony or excerpt, which would be a statement or quote from a specific person or source.
Option 2, "an argument," is incorrect because it suggests that reasoning or logic is being provided to support the claim. However, in the sentence provided, there is no indication that any reasoning or logic is being presented to support the claim that many people who do not get enough sleep each night suffer from illness and stress. Usually, an argument has a claim and evidence or reasoning to back up that claim.
Option 3, "a testimony or an excerpt," is incorrect because it suggests that a statement or quote is being provided from a specific person or source. However, in the sentence provided, there is no indication of a specific person or source providing the statement.

Different properties, significance of those properties and their applications in mathematics.
Associative property : Associative law states that the order of grouping the numbers does not matter. This law holds for addition and multiplication but it doesn’t hold for subtraction and division. This can be observed from the following examples.
Addition:
a+ (b+c) = (a+b) + c
Subtraction:
a-(b-c) ≠ (a-b) – c.
Multiplication:
a x (b x c) = (axb) x c
Division:
a ÷ (b ÷ c) ≠ (a ÷ b) ÷ c
Distributive property : This property is used to eliminate the brackets in an expression. The distributive property states that each term inside the bracket should be multiplied with the term outside. This property is very useful while simplifying the expressions and solving the complicated equations.
Addition:
a(b+c) = ab + ac
Subtraction :
a(b-c) = ab – ac

Do the equations 4x 3y 1 5 and 12x 9y 15 represent a pair of coincident lines?.
The given equations do not represent a par of coincident lines. As the equations do not satisfy the conditions.
It is given that the pair of equations are,

Solve each system using substitution
Answer:
Step-by-step explanation:
To solve the system of equations using substitution, we first need to isolate one of the variables in one of the equations. We can start by solving the first equation for y:
x - 5y = -6
y = (x + 6) / 5
Now we can substitute this expression for y into the second equation:
7x - 3y = 42
7x - 3((x + 6) / 5) = 42
Simplifying and solving for x:
(35/5)x - (3/5)x - 18/5 = 42
32x = 210+18
x=57/8
Now we can substitute this value of x back into the first equation to find the value of y:
y = ((57/8) + 6) / 5
y = 21/8
So the solution of the system is (x, y) = (57/8, 21/8).
