∠A and ∠B are vertical angles with m∠A=x and m∠B=3x−60 .
What is m∠A ?
Enter your answer in the box.
Answers
-3x -3x
____________
-2x = -60
-2x / -2 = -60 / -2
x=30
and m∠A = x , m∠B = 3x -60
So,
x = 3x -60
Now we solve this equation for x,
3x - x = 60
2x = 60
x = 30
Thus, the m∠A = 30 And m∠B = 3 (30) - 60 = 90 - 60 = 30
As, they are equal so, m∠A and m∠B is 30.

Which of the payment options would you recommend to a new employee?
Answers
The recommended method of pay must be salaried because, salaried employee will get more money than hourly paid employee per week.
Further explanation:
Given:
The salary of an employee is [tex]\$\ 78,000[/tex].
The hourly employee get paid is [tex]\$26\text{ /hour}[/tex] and after [tex]40[/tex] hour the employee get [tex]\$39\text{ /hour}[/tex].
Calculation:
The number of week in a year is [tex]52[/tex].
Therefore the salary of the employee per week can be obtained as follows:
[tex]\begin{aligned}\text{Salary per week}&=\dfrac{78000}{52}\\&=15000\end{aligned}[/tex]
The salary of the employ per week is [tex]\bf \$\ 1,500[/tex].
The number of hours worked by the hourly paid employee in the week is [tex]47\text{ hours}[/tex] since the sum of all the hours of the week is [tex]47[/tex].
The hourly paid employee works extra [tex]7\text{ hours}[/tex] per week.
The amount earned by hourly paid employee can be obtained as follows:
[tex]\begin{aligned}\text{Amount earned}&=(26\cdot 40)+(7\cdot 39)\\&=1040+273\\&=1313\end{aligned}[/tex]
Therefore, the dollars earned by the hourly paid employ per week is [tex]\$\1,313[/tex]
Since, the salaried employee make more money than and hourly paid employee per week.
Therefore, the highly recommended method of pay for new employee must be salaried.

The payment options would you recommend to a new employee is $1150.
The salary of $67,000, when divided by 52 weeks, results in a weekly payment of $1288.
For standard hourly employees working 44 hours per week, the breakdown is as follows: 40 regular hours at $25 per hour amounting to $1000, with an additional 4 hours of overtime at $37.50 per hour, totaling $150.
This computation reflects a fair compensation structure that considers both regular working hours and overtime, ensuring equitable remuneration for employees based on their hourly rates and the hours worked beyond the standard weekly timeframe.
Consequently, the total weekly compensation for hourly employees is $1150.

The coordinates of the vertices of quadrilateral JKLM are J(−3, 2) , K(3, 5) , L(9, −1) , and M(2, −3) .
Which statement correctly describes whether quadrilateral JKLM is a rhombus?
Quadrilateral JKLM is not a rhombus because there is only one pair of opposite sides that are parallel.
Quadrilateral JKLM is a rhombus because opposite sides are parallel and all four sides have the same length.
Quadrilateral JKLM is not a rhombus because there are no pairs of parallel sides.
Quadrilateral JKLM is not a rhombus because opposite sides are parallel but the four sides do not all have the same length
Answers
Using the distance formula, we can calculate the distances between the vertices of quadrilateral JKLM. After performing these calculations, we can determine that not all sides have the same length, thus quadrilateral JKLM is not a rhombus.
Explanation:To determine if quadrilateral JKLM is a rhombus, we need to check if all four sides are of equal length because a defining property of a rhombus is that it has all sides of equal length. The length between two points (x1, y1) and (x2, y2) can be found using the distance formula which is √[(x2-x1)² + (y2-y1)²].
After calculating, we find:
J-K distance = √[(5-2)² + (-3-3)²] = √42
K-L distance = √[(-1-5)² + (9-3)²] = √52
L-M distance = √[(-3- -1)² + (2-9)²] = √52
M-J distance = √[(2- -3)² + (-3-2)²] = √42
Therefore, the distance between vertices J-K and L-M are the same, and the distance between vertices K-L and M-J are the same, but the two pairs are not in themselves equal to each other. As such, quadrilateral JKLM is not a rhombus because all sides do not have the same length.

Use complete sentences to describe how a postulate becomes a theorem.
Answers
Final answer:
A postulate becomes a theorem through a process of logical deduction and proof. Starting from basic assumptions or postulates, mathematicians derive theorems using step-by-step logical inferences, forming the basis for further deductions, such as with Newton's second law or the Schrödinger equation in physics.
Explanation:
A postulate is a statement assumed to be true without proof and serves as a starting point for deducing and inferring other truths. The transformation from a postulate into a theorem involves a process of logical deduction and rigorous proof. When we establish a theorem, what we're doing is showing that the statement necessarily follows from the previously accepted postulates and theorems by a sequence of logical deductions. For example, in geometry, one might postulate that a straight line can be drawn between any two points, and from there, using a series of logical steps, derive the Pythagorean theorem. The Pythagorean theorem's validity is then supported by the fact that it can be derived from these fundamental postulates through a sequence of unassailable logical steps within a proof.
To illustrate, a textbook might first introduce a straightforward theorem like: "If we start out with four lines that form a rectangle, we can draw a new, fifth line that divides the rectangle into two identical triangles." From this, using the fifth line as a postulate, more complicated theorems can be constructed. Similarly, in physics, Newton's second law (f = ma) and the Schrödinger equation in quantum mechanics begin as postulates that explain a wide range of observations. Once propositions like these are established, they can be used to deduce further principles that build upon them.

Relationship B has a greater rate than Relationship A.
This graph represents Relationship A. Which equations could represent Relationship B?
Select each correct answer.
a) y = 3/4x
b) y = 0.6x
c) y = 1/4x
d) y = 2/3x
Answers
The equation (a) y = 3/4x, equation (b) y = 0.6x, equation (d) y = 2/3x are correct option because they have greater rate than A
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
We have;
Relationship B has a greater rate than Relationship A.
From the graph, the rate of A or slope will be:
A(m) = (4-2)/(8-4) = 2/4
A(m) =1/2 = 0.5
From the given option, the equation y = 3/4x, y = 0.6x, and y = 2/3x has a greater rate than A which is 3/4, 0.6, and 2/3 respectively.
Thus, the equation (a) y = 3/4x, equation (b) y = 0.6x, equation (d) y = 2/3x are correct option because they have greater rate than A

first you need to let A tickets to be x and B tickets to be y.
the first equation is 10x+60y=6000
the second equation is x+y=500
use one of the equation and make the one expression the subject. so i choose equation two.
x+y=500
x=500-y (equation 3)
sub equation 3 into equation 1,
10x+60y=6000
10(500-y)+60y=6000
5000-10y+60y=6000

x=500-20
x=480 tickets
therefore,
A tickets= 480 tickets
B tickets =20 tickets

Points A, B and Q are coplanar.
What are coplanar points?Points or lines are said to be coplanar if they lie in the same plane. Example 1: The points P , Q , and R lie in the same plane A . They are coplanar.
What are coplanar lines?A line which is in the same plane as another line. Any two intersecting lines must lie in the same plane, and therefore be coplanar.
What are collinear points?Three or more points that lie on the same line are collinear points . Example : The points A , B and C lie on the line m.
From the figure we can observe
Points A, B and Q are not in the same line.
Three points are collinear only if they are on the same line
3 points are collinear if we can draw a line that connects the points.
In the image A, Q are in a same line but B is not in the line of A and Q.
Points A, B and Q are on the base, So the three points are coplanar but not collinear.

Therefore its domain is x = [1,∞]
Answer: [1,∞]
Answer: The correct option is C. The domain of [tex](b\circ a)(x)[/tex] is [tex][0,\infty)[/tex].
Explanation:
It is given that,
[tex]a(x)=3x+1[/tex]
[tex]b(x)=\sqrt{x-4}[/tex]
First we have to find the composite function [tex](b\circ a)(x)[/tex].
[tex](b\circ a)(x)=b(a(x))[/tex]
[tex](b\circ a)(x)=b(3x+1)[/tex]
[tex](b\circ a)(x)=\sqrt{3x+1-4}[/tex]
[tex](b\circ a)(x)=\sqrt{3x-3}[/tex]
We know that a root function is defined for only positive values therefore the composite function is defined if,
[tex]3x-3\geq 0[/tex]
[tex]3x\geq 3[/tex]
[tex]x\geq 1[/tex]
The function is defined for all the values of x which are greater than or equal to 1. Therefore the domain of [tex](b\circ a)(x)[/tex] is [tex][0,\infty)[/tex] and option C is correct.
