What are three collinear points on line l?
points A, B, and F
points A, F, and G
points B, C, and D
points B, F, and G
Points A, F, and G are three collinear points on line l.
[tex]\boxed{ \ The \ Answer \ is \ B \ }[/tex]
Further explanationLet us consider the definition of collinear.
Collinear
Collinear points represent points that lie on a straight line. Any two points are always collinear because we can constantly connect them with a straight line. A collinear relationship can occur from three points or more, but they don’t have to be.
Noncollinear
Noncollinear points represent the points that do not lie in a similar straight line.
Given that lines k, l, and m with points A, B, C, D, F, and G. The logical conclusions that can be taken correctly based on the attached picture are as follows:
At line k, points A and B are collinear. At line l, points A, F, and G are collinear. At line m, points B and F are collinear. Point A is placed at line k and line l.Point B is placed at line k and line m.Point F is located at line l and line m.Points C and D are not located on any line.Hence, the specific answer to this key question is undoubted, i.e., points A, F, and G.
Note:
All points can, also, be said to be coplanar. This is because the three lines intersect with each other and lie on a planar surface.
Coplanar
Coplanar points represent a group of points that lie on the same plane, i.e. a planar surface that extends without end in all directions. Any two or three points are always coplanar, but four or more points might or might not be coplanar.

Luisa draws a regular nonagon and rotates it about its center. which angle measures can luisa rotate the regular nonagon through to map it onto itself? select each correct answer. 40° 80° 90° 120° 160° 180°
Answer: [tex]40^{\circ}[/tex]
Step-by-step explanation:
Given: A regular nonagon with 9 sides.
For a regular nonagon, it maps onto itself 9 times during a rotation of 360°.
Mow, the angle at Lusia can rotate the regular nonagon through to map it onto itself=[tex]\frac{360}{\text{number of sides of regular polygon}}=\frac{360}{9}=40^{\circ}[/tex]
A shape is said to has rotational symmetry if it maps onto itself under rotation about a point at its center. The order of rotational symmetry is the number of times the shape maps onto itself during a rotation of 360°.A shape that maps onto itself after rotation, has a rotation symmetry
The angles of rotation that would map the nonagon onto itself are:
[tex]\mathbf{40, 80, 120\ and\ 160}[/tex]
A regular nonagon has nine equal sides i.e.
[tex]\mathbf{n = 9}[/tex]
The angle at the center of the nonagon is:
[tex]\mathbf{\theta = 360}[/tex]
So, the angle of rotation symmetry is:
[tex]\mathbf{\alpha = \frac{\theta}{n}}[/tex]
This gives:
[tex]\mathbf{\alpha = \frac{360}{9}}[/tex]
[tex]\mathbf{\alpha = 40}[/tex]
This means that, the nonagon would map onto itself, when rotated at 40 degrees.
Other angles of rotation symmetry must be a multiple of 40
i.e.
[tex]\mathbf{\alpha = 40, 80, 120, 160, 200, 240, 280......}[/tex]
Using the above list of angles, the angles of rotation that would map the nonagon onto itself are:
[tex]\mathbf{40, 80, 120\ and\ 160}[/tex]

Point V lies between points U and W on UW.
If UW = 9x – 9, what is UW in units?
5 units
6 units
30 units
36 units
Answer: The correct option is (D) 36 units.
Step-by-step explanation: Given that point V lies between points U and W on UW, where
[tex]UV=2x-4,~~VW=4x+10~~~\textup{and}~~~UW=9x-9.[/tex]
We are to find the length of UW in units.
Since point V lies on the line segment UW, so we must have
[tex]UV+VW=UW\\\\\Rightarrow (2x-4)+(4x+10)=9x-9\\\\\Rightarrow 6x+6=9x-9\\\\\Rightarrow 9x-6x=6+9\\\\\Rightarrow 3x=15\\\\\Rightarrow x=5.[/tex]
Therefore, the length of UW is
[tex]UW=9x-9=9\times5-9=45-9=36~\textup{units}.[/tex]
Thus, the length of UW is 36 units.
Option (D) is correct.
A rate that describes how much smaller or larger the scale drawing is than then real object
The scale factor is a ratio that describes the relationship between the dimensions of a scale drawing and the real object that it represents. A larger scale factor indicates a greater level of detail in the drawing, while a smaller scale factor depicts less detail and a larger area.
Explanation:The rate that describes how much smaller or larger the scale drawing is than the real object is known as the scale factor. A scale factor is a ratio that compares the dimensions of the actual object to the dimensions of a scale drawing or model. For example, a scale factor may be written as 1/200, meaning that the real object is 200 times larger than the scale drawing.
Scale can also be described using terms such as 'small' or 'large' scale. These terms relate to the level of detail a map shows; a large-scale map, with a representative fraction of 1:1,000, shows more detail and less area whereas a small-scale map, with a representative fraction of 1:1,000,000, shows less detail and more area.
Understanding these concepts is essential when interpreting maps and drawings as they communicate the level of zoom and detail. Remember, scale refers to a ratio and not the physical size of the map or drawing itself.
Which statement best explains how Lizabeth develops the theme in "Marigolds" that beauty can be appreciated even in the worst circumstances?
Answer:
Lizabeth remembers the poverty of her childhood hometown but also the marigolds in Miss Lottie's yard.
Explanation:
The short story "Marigolds" by Eugenia Collier is a story of a little girl's childhood experience. In the story, Lizabeth talks of how her community is impoverished, "—the brown, crumbly dust of late summer—arid, sterile dust that gets into the eyes and makes them water, gets into the throat and between the toes of bare brown feet". But despite the background image of poverty all around her, she could also remember "a brilliant splash of sunny yellow against the dust—Miss Lottie’s marigolds". Through her remembering of the marigolds amidst the poverty of her childhood hometown, Lizabeth develops the theme of beauty appreciated even in the worse circumstances.

James age in years is five more than two timed kevin's age. If James is 19 years old , how many years old is kevin?
Final answer:
Kevin is 7 years old. The problem is solved by setting up an equation 19 = 2K + 5, subtracting 5 from both sides to get 14 = 2K, and then dividing by 2 to find Kevin's age.
Explanation:
The question asks us to find Kevin's age given that James's age is five more than two times Kevin's age and that James is 19 years old. To solve this, we'll set up an equation based on the information provided.
Let K represent Kevin's age. According to the problem, we have:
James's age = 2 × Kevin's age + 5
Since James's age is 19, we can write:
19 = 2K + 5
To solve for K, we first subtract 5 from both sides of the equation:
14 = 2K
Then, we divide both sides by 2 to isolate K:
K = 7
Therefore, Kevin is 7 years old.
Wallace received a 28 percent discount on an item priced at $275. What is the total price that he paid for it? cost after discount = price × (1 – discount percentage)
Answer: $198
Step-by-step explanation:
Given: The discount percentage : 28 % =0.28
The price of item = $275
The given formula for total cost of item after discount :
[tex]\text{Cost after discount = Price *(1 – Discount percentage)}[/tex]
Substitute the value of price =$275 and discount percent = 0.28 in the above formula , we get
[tex]\text{Cost after discount =}275\times(1-0.28)\\\\\Rightarrow\ \text{Cost after discount =}275\times0.72\\\\\Rightarrow\ \text{Cost after discount =}\$192[/tex]
Hence, he paid the total price of $198 for it.

y = arctan(8/10)
y = 38.65
y = 39
Answer:
Option (b) is correct.
The measure of angle y is 39°
Step-by-step explanation:
Given : A right angled triangle with some measurements.
We have to find the value of y.
Consider the given triangle,
Using trigonometric ratios,
We know tangent is the ratio of perpendicular to its base.
Mathematically written as
[tex]\tan\theta=\frac{Perpendicular}{base}[/tex]
So, for given triangle, [tex]\theta=y[/tex]
and for y, perpendicular is 8 and base is 10
Substitue, we have,
[tex]\tan y=\frac{8}{10}[/tex]
Simplify, we have,
[tex]\tan y=\frac{4}{5}[/tex]
Taking inverse of tan both side, we have,
[tex]\tan^{-1}(\tan y)=\tan^{-1}(\frac{4}{5})[/tex]
[tex]y=\tan^{-1}(\frac{8}{10})[/tex]
Simplify , we have,
[tex]y=38.65^{\circ}[/tex]
Thus, the measure of angle y is 39°
In the figure, BC and AD are line segments. What is the sum of x and y?
Answer:
The correct option is 2.
Step-by-step explanation:
Given information: BC and AD are line segments.
According to the angle sum property, the sum of interior angles of a triangle is 180°.
In triangle DOC,
[tex]\angle C+\angle COD+\angle D=180^{\circ}[/tex]
[tex]y+64^{\circ}+54^{\circ}=180^{\circ}[/tex]
[tex]y+118^{\circ}=180^{\circ}[/tex]
[tex]y=180^{\circ}-118^{\circ}[/tex]
[tex]y=62^{\circ}[/tex]
The value of y is 62°.
If two lines intersect each other then vertical opposite angles are equal.
[tex]\angle COD=\angle AOB=64^{\circ}[/tex]
In triangle AOB,
[tex]\angle A+\angle AOB+\angle B=180^{\circ}[/tex]
[tex]x+64^{\circ}+62^{\circ}=180^{\circ}[/tex]
[tex]x+126^{\circ}=180^{\circ}[/tex]
[tex]x=180^{\circ}-126^{\circ}[/tex]
[tex]x=54^{\circ}[/tex]
The value of x is 54°.
The sum of x and y is
[tex]54^{\circ}+62^{\circ}=116^{\circ}[/tex]
The sum of x and y is 116°. Therefore the correct option is 2.
