In ∆WXY, if∠X ≅ ∠Y , WX = 9x – 11, XY = 4x + 1, and WY = 7x – 3, find x and the measure of each side.
Answer:
12)x=26.125°
∠P = 115.625°
∠Q =21.125°
∠R=43.25°
13)x=52°
∠L=52°
∠J =45°
∠K =69°
14)x=11°
∠C = 36°
∠D =36°
∠B = 108°
15)x=7
WX = 52
WY=52
XY =29
Step-by-step explanation:
12)In ∆PQR
∠P is 14 less than five times x = 5x-15
∠Q is five less than x=x-5
∠R is nine less than twice x=2x-9
Angle sum property of triangle : The sum of all angles of triangle is 180°
So,5x-15+x-5+2x-9=180
8x-29=180
8x=180+29
\(x=\frac{180+29}{8}\)
x=26.125
So,∠P = 5x-15 =5(26.125)-15=115.625°
∠Q =x-5=26.125-5=21.125°
∠R=2x-9=2(26.125)-9=43.25°
13) In ∆JKL
Let the angle L be x
∠L=x
∠J is seven less than ∠L=x-7
∠K is 21 less than twice ∠L=2x-21
Angle sum property of triangle : The sum of all angles of triangle is 180°
So, x+x-7+2x-21=180°
4x-28=180°
4x=180+28
\(x=\frac{180+28}{4}\)
x=52
∠L=x=52°
∠J =x-7=52-7=45°
∠K =2x-21=2(45)-21=69°
14)In ∆BCD
BC ≅ BD(Given)
Opposite angles of equal sides are equal
So, ∠C =∠D
∠C = 5x – 19
∠D = 2x + 14
So, 5x-19=2x+14
3x=33
x=11
∠C = 5x – 19=5(11)-19=36°
∠D = 2x + 14=2(11)+14=36°
∠B = 13x – 35=13(11)-35=108°
15) In ∆WXY
∠X ≅ ∠Y(Given)
Opposite sides of equal angles are equal
WY=WX
WX = 9x – 11
WY = 7x – 3
So, 9x-11=7x-3
2x=14
x=7
So, WX = 9x – 11=9(7)-11=52
WY=52
XY = 4x + 1=4(7)+1=29

Xavier needs to print some color copies for a presentation, and he has a coupon. His cost y in dollars to print x copies is y = 0.08x – 2.50.
2.50 is the coupon amount and 0.08 is the cost for one copy from the equation y = 0.08x - 2.50.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
y = 0.08x - 2.50
Where x is the number of copies and y is the cost of printing x copies.
Now,
From the equation,
y = 0.08x - 2.50
2.50 is the coupon amount.
0.08 is the cost for one copy.
Thus,
2.50 is the coupon amount.
0.08 is the cost for one copy.

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $20,000 and $35,000. Assume tha a 95% confidence interval estimate of the population mean annual starting salary is desired, a. What is the planning value for the population standard deviation? σ= b. How large a sample should be taken if the desired margin of error is $300? Round your answers to next whole number. $230? 4100? C. Would you recommend trying to obtain the 8100 maroin of error? Explain.
The planning value for the population standard deviation is unknown and must be estimated. Since a large enough sample size is selected (say n > 30), the sample standard deviation s is typically a decent approximation of σ.
Therefore, to obtain σ, use the formula for s and replace s with its symbol in the formula to get the estimate of (Rounded to the nearest whole number) Here, σ is the planning value for the population standard deviation. The margin of error (E) is the difference between the true population mean μ and the sample mean .
In this scenario, the margin of error (E) is $300, thus E = $300. Therefore, solving for the required sample size:n = (zα/2)^2 * σ^2 / E^2We are given: σ = 2500, E = $300 and the confidence level is 95%. This implies that α = 0.05, hence zα/2 = z0.025 = 1.96 (from z-distribution table). Substituting the values:n = (1.96)^2 * 2500 / 300^2= 105.51 ≈ 106Sample size required is 106 (rounded to the nearest whole number). Here, the sample size is 0.003 which is practically impossible. Thus, the required margin of error should not be pursued.

What is Square Number?A "Square Number" is the product of multiplying an integer or number (not a fraction) by itself. For instance, 3 x 3 = 32, or 3 multiplied by 3 becomes 3 squared. In essence, a square number is the result of multiplying an integer or number by itself exponentially. Additionally, if we multiply the number once more by itself, we obtain the integer's cube: an x an x a = a3. The resultant number is referred to as a square number when an integer is multiplied by another integer. For instance, we obtain 25 when we multiply 5 x 5 = 52. Here, the number 25 is a square. Square numbers cannot be negative because when a negative number is multiplied by a positive one, it becomes a square number.To learn more about Square Number refer to:

The correct option is A. m ≤ (8)(20)
The inequality which gives the possible values of 'm' is m ≤ (8)(20).
What is inequality?A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
According to the question;
Terrence's car contains 8 gallons of fuel.
Terrence can drive the car 'm' miles using the fuel currently in the car.
The car can drive 20 miles per gallon of fuel,(which is maximum fuel capacity of the car to drive).
Then,
The total miles 'm' covered by the car is 8×20 which is maximum capacity of the car to travel.
Thus, total miles covered by the car are less than the maximum value which is given by the inequality-
m ≤ (8)(20)
Therefore, the inequality which gives the possible values of 'm' is m ≤ (8)(20).

The cheerleading squad is selling raffle tickets for their fundraiser. Each ticket cost two dollars and the prize for the winner is $50. How many tickets does the team need to sell in order to raise $175?
When each ticket costs $2, and the prize for the winner is $50 then the cheerleading squad needs to sell at least 88 tickets to raise $175.
The cheerleading squad wants to raise $175 through their raffle ticket sales.
Each ticket costs $2, and the prize for the winner is $50. We need to determine how many tickets the team needs to sell to reach their fundraising goal.
Let's assume the number of tickets the team needs to sell is 'x'.
Since each ticket costs $2, the total revenue generated from ticket sales can be calculated as 2 * x.
To reach their fundraising goal of $175, the total revenue from ticket sales should be equal to $175.
Therefore, we can set up the equation:
2 * x = 175
Solving for 'x', we divide both sides of the equation by 2:
x = 175 / 2
Simplifying further, we get:
x = 87.5
Since we cannot sell a fractional number of tickets, we round up the value to the nearest whole number.
Therefore, the cheerleading squad needs to sell at least 88 tickets to raise $175.
It's worth noting that selling exactly 87 tickets would only generate $174 in revenue, which is less than the fundraising goal.
Hence, they need to sell a minimum of 88 tickets to reach or exceed their target of $175.

Let A (a. b, c). For each of the following, draw a directed graph that represents a relation with the specified properties. (a) A relation on A that is symmetric but not transitive (b) A relation on A that is transitive but not symmetric (c) A relation on A that is symmetric and transitive but not reflexive on A (d) A relation on A that is not reflexive on A, is not symmetric, and is not transitive (e) A relation on A, other than the identity relation, that is an equivalence relation on A
(a) A relation on A that is symmetric but not transitive:
In this case, let's assume A = {a, b, c}.
To create a relation that is symmetric but not transitive, we can set up the following directed graph:
a b c
┌───┐ │ ┌───┐

In this graph, there are directed edges between 'a' and 'b', 'b' and 'a', 'b' and 'c', and 'c' and 'b'. However, there is no directed edge between 'a' and 'c' or 'c' and 'a'. This satisfies the condition of symmetry but fails the transitivity condition.
(b) A relation on A that is transitive but not symmetric:
Again, considering A = {a, b, c}, we can set up the following directed graph:
a b c
┌───┐ └───┐
│ │ ┌───┘
└───┘ │
└───┘
In this graph, there is a directed edge from 'a' to 'b', 'b' to 'c', and 'a' to 'c'. However, there is no directed edge from 'b' to 'a' or 'c' to 'b'. This satisfies the condition of transitivity but fails the symmetry condition.
(c) A relation on A that is symmetric and transitive but not reflexive on A:
Using A = {a, b, c}, we can set up the following directed graph:
a b c
┌───┐ └───┐
│ │ ┌───┘
└───┘
In this graph, there are directed edges between 'a' and 'b', 'b' and 'a', 'b' and 'c', and 'c' and 'b'. The graph satisfies the symmetry and transitivity conditions. However, there are no loops or self-edges, indicating that the relation is not reflexive.
(d) A relation on A that is not reflexive, not symmetric, and not transitive:
For this case, we can set up the following directed graph:

a b c
┌───┐ ┌───┐

└───┘ └───┘
In this graph, there are no directed edges between any pair of elements. Since there are no directed edges, the relation fails to satisfy reflexivity, symmetry, and transitivity.
(e) An equivalence relation on A (other than the identity relation):
Considering A = {a, b, c}, we can set up the following directed graph:

┌───┐ ┌───┐
