Answers
When QP bisects DQL, then the angles DQP and angle PQL is 23°.
Given that,
In the picture we can see the diagram,
The QL line is there and the QD line.
QP line bisect the angles DQL
The angle DQP is 5x-7
The angle PQL is 11+2x
We have to find the x value and the angles DQP and PQL.
We know,
From the bisection we can say the angle are equal to each other
The angle DQP=The angle PQL
5x-7=11+2x
5x-2x=11+7
3x=18
x=18/3
x=6
Substitute x value in angles DQP and angle PQL.
The angle DQP=5x-7=5(6)-7=30-7=23°
The angle PQL=11+2x=11+2(6)=11+12=23°.
Therefore, the angles DQP and angle PQL is 23°.

Answers
The two triangles are not similar to each other.
What is perimeter?The perimeter of the triangle is the sum of the lengths of all its sides.
The angle of triangle = 62
The two equal angles = [4(x +2)] and (5x - 7)
According to the question,
The Perimeter of triangle are;
[4(x +2)] + (5x - 7) + 62 = 180
4x + 8 + 5x - 7 + 62 = 180
9x + 63 = 180
9x = 117
x = 13
The other triangle is
6x + 62 + 6x + 6 = 180
12x + 68 = 180
12x = 112
x = 9.33

What is the value of x, y, and z??
Answers
The values x = 0, y = 0.03 and z = 0.039 for the three events A,B and C with their associated probabilities.
Axioms of probabilityThe following are axioms of probability for the purpose of answering the given question:
Two events are said to be mutually exclusive if the probability of their intersection is zero.
Two events are said to be independent if the probability of their intersection is equal to the product of their respective probability
From the question, the probability of the event A alone occurring=0.10
the probability of the event B alone occurring=0.30
the probability of the event C alone occurring=0.39
Given that B and C are mutually exclusive events;
x = probability of the intersection of B and C=0
A and C are said to be independent so; z = probability of the intersection of A and C = 0.10×0.39
probability of the intersection of A and C = 0.039
If A and B are not mutually exclusive events and are independent then;
y = probability of the intersection of A and B
probability of the intersection of A and B = 0.10×0.30
probability of the intersection of A and B = 0.03.
Hence, the values of x,y and z are 0, 0.03 and 0.039 respectively for the events A,B and C with their associated probabilities.

please help
Answers
Quinn got paid $121,560 in his first career and on switching, he made 55% less, i.e. he made 45% of his previous career.
This is because, if in a previous career he made 100%, then a 55% reduction in salary annually would mean, he is left with only 45%.
Let us suppose, previous salary as x
then, x= $121,560
so, 45% of x= 45% of $121,560
i.e. 45% of x= 45/100 x 121560
therefore, 45% of x= $54,702
Quinn makes $54,702 now.
Therefore, a reduction in 55% of earlier salary would mean that Quinn's salary reduced from $121,560 to $54,702

Answers
The measure of each angle in the diagram is as follows:
3y + 11 = 50 degrees10y = 130 degrees(4x - 22) = 50 degrees7x + 4 = 130 degreesHow to find the angles in intersecting lines?When lines intersect, angle relationships are formed such as vertically opposite angles, adjacent angles etc.
Therefore, the measure of each angle in the diagram can be calculated as follows:
10y = 7x + 4 (vertically opposite angles)
3y + 11 = 4x -22(vertically opposite angles)
Therefore,
10y - 7x = 4
3y - 4x = -22 - 11
10y - 7x = 4
3y - 4x = -33
multiply equation(ii) by 1.75
10y - 7x = 4
5.25y - 7x = - 57.75
subtract equation(ii) from equation(i)
Hence,
4.75y = 61.75
y = 61.75 / 4.75
y = 13
Therefore,
10(13) - 7x = 4
130 - 7x = 4
130 - 4 = 7x
7x = 126
x = 126 / 7
x = 18
Therefore, the unknown angles are as follows;
3y + 11 = 3(13) + 11 = 50 degrees10y = 10(13) = 130 degrees(4x - 22) = 4(18) - 22 = 50 degrees7x + 4 = 7(18) + 4 = 130 degreeslearn more on angles here: https://brainly.com/question/18193074

A)Angle A and B are vertical angles, meaning they are equal in measure. We can solve for y by setting the two equations equal to each other.
Vertical angles are the opposite angles formed by the intersection of 2 lines.
Supplementary angles are angles that add up to 180°.
Solve for y4y - 25 = 674y = 92y = 23The value of y is 23°.
B)Measure of Angle A is 67°, as Angle A and B are vertical and equal in measure
Measure of Angle C is 113°, because the sum of angles on a line are equal to 180°, and are supplementary.
Measure of Angle D is also 113°, because it is vertical to Angle C.

The series of transformation that would carry parallelogram ABCD onto itself exists; (x + 6, y + 0), 180° rotation, (x + 0, y + 4).
What is the series of transformations in a parallelogram ABCD?The coordinates of the vertex of the parallelogram are;
A(-5, 1), B(-4, 3), C(-1, 3), and D(-2, 1)
The coordinate of the point (x, y) following a rotation 180° about the origin is the point (-x, -y)
Following a rotation of the parallelogram ABCD about the origin we get;
A'(5, -1), B'(4, -3), C'(1, -3), and D'(2, -1)
Given that the parallelogram exists symmetrical following rotation of 180°, we have;
The top rightmost point in the image A'B'C'D', A'(5, -1) corresponds to the top rightmost point on the preimage, point C(-1, 3)
Similarly, we have;
Point B'(4, -3), corresponds to point D(-2, 1)
Point D'(2, -1), corresponds to point B(-4, 3)
The difference in the corresponding points are;
Difference in x-values = 4 - (-2) = 6
Difference in y-values = -3 - 1 = -4
Which gives; T₍₆, ₋₄₎, which exists magnitudes similar to the third option
Therefore; by (x + 6, y + 0), 180° rotation, (x + 0, y + 4), we have;
Adding 6 to the x-values before rotation gives;
A''(-5 + 6, 1), B''(-4 + 6, 3), C''(-1 + 6, 3), and D''(-2 + 6, 1)
A''(1, 1), B''(2, 3), C''(5, 3), and D''(4, 1)
Rotating 180° about the origin gives;
A'''(-1, -1), B'''(-2, -3), C'''(-5, -3), and D'''(-4, -1)
Adding 4 to the y-values gives;
A''''(-1, -1 + 4), B''''(-2, -3 + 4), C''''(-5, -3 + 4), and D''''(-4, -1 + 4)
A''''(-1, 3), B''''(-2, 1), C''''(-5, 1), and D''''(-4, 3), which are the coordinates of the image;
A''''(-1, 3) ⇔ C(-1, 3)
B''''(-2, 1) ⇔ D(-2, 1)

Given f(x)=2x-5, describe how the graph of g compares with the graph of f.
g(x)=2(0.2x)-5
Answers
The graph of g and f have equal intercepts while the slope of the graph of f is 5 times larger than the slope of the graph of g
How to compare the graph of g with the graph of fGiven: f(x) = 2x-5 and g(x)=2(0.2x)-5
To compare the two graphs, we can make use of the equation of a line:
The general form of the equation of a line is y = mx + c
Where m is the slope and c is the intercept
So we will compare two the functions with the equation of a line:
Comparing f(x) = (2x-5) with y = mx + c
The slope(m) of the line = 2 and the intercept(c) = -5
Also, comparing g(x) = 2(0.2x)-5 with y = mx + c
The slope(m) of the line = 2(0.2) = 0.4 and the intercept(c) = -5
Since the slope of f(x) = 2 and the slope of g(x) = 0.4. Thus:
slope of f(x) / slope of g(x) = 2/0.4 = 5
So we can say the slope of f(x) is 5 times the slope of g(x)
Therefore, the graph of g and f have the same intercept. But the slope of f(x) is 5 times the slope of g(x)
