A)14; 94°
B)16; 106°
C)19; 124°
D)15; 100°
Answer:
D)15; 100°.
Step-by-step explanation:
Given : Verticle opposite angles (6a + 10) and (3a + 55).
To find : Find the value of a. b. Find the value of the marked angles.
Solution : We have given (6a + 10) and (3a + 55).
Verticle opposite angles are equal
Then
6a + 10 = 3a + 55
On subtracting both sides by 3a
6a - 3a + 10 = 55
3a + 10 = 55
On subtracting by 10 both sides.
3a = 55 -10.
3a = 45.
On dividing the 3 by both sides
a = 15°.
Then ,
6 (15) + 10.
90 + 10 = 100
b =100°.
Therefore, D)15; 100°.

3ax + 2b / c = 4d solve for x
Final answer:
To solve the equation 3ax + 2b / c = 4d for x, isolate x on one side of the equation by multiplying both sides by c, subtracting 2b, and dividing by 3a.
Explanation:
To solve the equation 3ax + 2b / c = 4d for x, we need to isolate x on one side of the equation. Here are the steps:
Multiply both sides of the equation by c to get rid of the denominator: 3ax + 2b = 4cd.Subtract 2b from both sides of the equation: 3ax = 4cd - 2b.Divide both sides of the equation by 3a to solve for x: x = (4cd - 2b) / (3a).Therefore, the solution for x is x = (4cd - 2b) / (3a).
Rule that maps each preimage
A function is a rule that maps each preimage to a unique image.
Explanation:A rule that maps each preimage to a unique image is called a function. In mathematics, a function is a relation between a set of inputs (preimages) and a set of outputs (images) in which each input is associated with exactly one output.
For example, consider the function f(x) = 2x, where the input x is a preimage and the output 2x is the corresponding image. If we plug in x = 3, the preimage, we get f(3) = 2(3) = 6, the image.
Functions are commonly represented using algebraic expressions, tables, graphs, or diagrams. They are fundamental to many branches of mathematics and have applications in various fields. The phrase 'rule that maps each preimage' refers to the function or transformation that defines how to manipulate a preimage to obtain an image, either by applying a mathematical formula or by executing a geometric operation.

Contrast the tone of the following two passages. (First, determine the tone of each passage. Then determine how the tones differ. What is the tone of each? How do you know? How do the tones differ?)
Tone ONE
Envisioning paths where Russell’s discovery could lead him, Rosalind and I began grooming him for interviews with the local news and math journals. In our minds, Russell’s future was bright and without limitation, starting with a full scholarship to MIT or Northwestern.
Tone 2
I came home for brief visits, but these visits were too awkward without Rosalind. The house was profoundly still. Mommy stayed in her room. Russell didn’t talk, let alone look at me.
The first passage has a hopeful and ambitious tone, using optimistic language to express excitement for the future. The second passage has a melancholic and isolated tone, using somber phrases to convey discomfort and disconnection. These contrasting tones reflect a range of emotions in the narrative.
Explanation:To contrast the tone of two passages, we must first identify the attitude or mood present in each. In Tone ONE, the writer’s use of optimistic phrases such as "Envisioning paths," "grooming him for interviews," and "future was bright" convey a hopeful and ambitious tone. This tone suggests excitement for the future possibilities and success that lie ahead for Russell.
In contrast, Tone 2 uses phrases like "too awkward," "profoundly still," and "didn’t talk" which reveal a somber, isolated and possibly melancholic tone. It reflects the author’s feelings of discomfort, silence, and the lack of communication and connection with the family.
The two tones differ significantly, with the first being uplifted and forward-looking, while the second expresses a sense of disconnection and sadness, giving us a comprehensive view of the contrasting emotional landscapes in the same narrative context.
Triangle DEF is formed by the three squares P, Q, and R:
A right triangle DEF is shown. On the side DE of this triangle is a square. Inside the square is written Square P, and below it and inside the square is written Area equal to 64 square units. On the side EF of this triangle is another square. Inside the square is written Square Q, and below it and inside the square is written Area equal to 225 square units. On the side DF of this triangle is another square. Inside the square is written Square R, and below it and inside the square is written Area equal to 289 square units.
Which statement best explains the relationship between the sides of triangle DEF?
DE + EF = DF, because 64 + 225 = 289
(DE)2 + (EF)2 = (DF)2, because 172 + 82 = 152
(DE)2 + (EF)2 = (DF)2, because 64 + 225 = 289
DE + EF = DF because, 172 + 82 = 152
using the Pythagorean Theorem
a^2 + b^2 = C^2
so correct answer is:
(DE)2 + (EF)2 = (DF)2, because 64 + 225 = 289
Answer:
(DE)2 + (EF)2 = (DF)2, because 64 + 225 = 289

A piece of land is to be fenced and subdivided as shown so that each rectangle has the same dimensions. Express the total amount of fencing needed as an algebraic expression in x.
If two or more rectangles have the same dimensions is because they are congruent. In this way, they share two corresponding sides. Our first rectangle has the following sides:
L1 = x
L2 = 3x + 4
Therefore the second and third rectangles need to have the same sides. Therefore, we will have that the sides of the second one is also:
L1 = x
L2 = 3x + 4
and the sides of the third one is also:
L1 = x
L2 = 3x + 4
Therefore, the total amount of fencing needed is:
T = 3(3x + 4) + 4(x)
T = 9x + 12 + 4x
T = 13x + 12
Moreover, we can compute the area of the fence as follows:
A = [(3x + 4) + (3x + 4) + (3x + 4)]x = (3x + 3x + 3x + 4 + 4 + 4)x
A = (9x + 12)x
A = 9x² + 12x
The algebraic expression that expresses the total amount of fencing needed is 11X + 20.
CalculusGiven that a piece of land is to be fenced and subdivided as shown so that each rectangle has the same dimensions, to express the total amount of fencing needed as an algebraic expression in X, the following calculation must be performed:
3X + 4 = 6 wooden fence blocksEach rectangle has 3 blocks on each side and 6 blocks in front.Number of fronts = 3Number of sides = 4(3X + 4) x 3 + ((3X + 4) x 4) / 2 = Algebraic expression9X + 12 + (4X + 16) / 2 = Algebraic expression9X + 12 + 2X + 8 = Algebraic expression11X + 20 = Algebraic expressionTherefore, the algebraic expression that expresses the total amount of fencing needed is 11X + 20.

What are the steps for using a compass and straightedge to construct a line through point A that is parallel to line j?
A horizontal line j and a point A are drawn. The point A is below the horizontal line j.
Drag the steps and drop them in order from start to finish.
Place the point of the compass on point Q and open it to width QR .
Use the straightedge to draw a line k that passes through A and intersects line j. Label the point of intersection as point P.
Use the straightedge to draw AB←→.
Without changing the width of the compass opening, place the point of the compass on point A and draw an arc that intersects line k. Label the intersection as point S.
With the compass opening set to width QR , place the point of the compass on point S and draw an arc that intersects the arc that was drawn from point A. Label the intersection of the arcs as point B.
Place the point of the compass on point P and draw an arc that intersects lines j and k. Label the intersections as points Q and R.
Answer:
Step 1: Use the straightedge to draw a line k that passes through A and intersects line j. Label the point of intersection as point P. This is because you must have a point of intersection with the line before you can move forward.
Step 2: Place the point of the compass on point P and draw an arc that intersects lines j and k. Label the intersections as points Q and R. This will give us a compass width to move forward.
Step 3: Place the point of the compass on point Q and open it to width QR.
Step 4: Without changing the width of the compass opening, place the point of the compass on point A and draw an arc that intersects line k. Label the intersection as point S. This gives us the point to use to construct the second point of our parallel line.
Step 5: With the compass opening set to width QR , place the point of the compass on point S and draw an arc that intersects the arc that was drawn from point A. Label the intersection of the arcs as point B. This is the second point of our parallel line.
Step 6: Use the straightedge to draw AB←→.
The steps are shown below:
