Answer:
True
Step-by-step explanation: because they have 4 sides
All quadrilaterals are polygons because they are 2-dimensional closed shapes made up of interconnected straight lines, with four sides and angles.
Hence the given statement is true.
Sincw we know that,
A polygon is defined as a 2-dimensional closed shape made up of straight lines that are interconnected with each other at their endpoints. A Quadrilateral is a polyhedron that consists of four straight sides or edges.
The term quadrilateral is derived from two Latin words "quadri" meaning four and "latus" meaning sides.
It is important to note that not all polygons are quadrilaterals, but all quadrilaterals are indeed polygons.
Some examples of quadrilaterals include squares, rectangles, parallelograms, trapezoids, and rhombuses.
These shapes share certain properties such as having four sides and angles, with the sum of their interior angles adding up to 360 degrees.

If triangle ABC has the following angle measurements, find the value of Angle A, Angle B, and Angle C.
∠A=4x − 17
∠B= 3x + 8
∠C= x + 13
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x - 17 + 3x + 8 + x + 13 = 180
8x + 4 = 180
8x = 176
x = 22
<A = 4x - 17
<A = 4*22 - 17

Givethanks, an Indian, wants to have a turkey dinner. He and his “dog”, Wolf, go looking for a turkey. While on this turkey hunt, they come across a field of corn. Givethanks just has to have some of the corn and picks some to take home. While in the corn field, Givethanks spots the biggest turkey he has ever seen and captures it. On the way home to his village, Givethanks and Wolf come to a river where there is a small boat that will only fit Givethanks and one other thing. Now, Givethanks wants to get Wolf, the turkey and the corn across the river, but Wolf will eat the turkey if they are left alone and the turkey will eat the corn if it is left alone with the corn.
Your Task: Figure out how Givethanks will get Wolf, the turkey and the corn across the river. You must show how you feel he can accomplish this task. You must write a paragraph explaining how you feel you can accomplish this task.
I need help with this.
Answer: The man and the turkey cross the river, (the wolf and corn are safe together), he leaves the turkey on the other side and goes back across.
The man then takes the wolf across the river, and since he can't leave the wolf and turkey together, he brings the turkey back.
Again, since the turkey and corn can't be left together, he leaves the turkey and he takes the corn across and leaves it with the wolf.
He then returns to pick up the turkey and heads across the river one last time.

Is the relation a function? {(3,4), (5,0), (2,4), (-5,-5)}
Answer:
Yes
Step-by-step explanation:
You are using the x values once, so it will pass the vertical line test.
{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The relation is {(3,4), (5,0), (2,4), (-5,-5)}
Relation on a set may, or may not, hold between two given set members.
Three comma four comma five comma zero two comma four comma minus five comma minus five.
{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function, because in (x,y) the x terms are not repeated.
For every y value there is a unique x value.
Hence, {(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

Which equation, in slope-intercept form, passes through (–2, 4) and has a
slope of 3?
F. y = 3x - 2
G. y = 3x + 10
H. y = 3x - 10
I. y = 3x +2
Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10

'A circle is a shape consisting of all points in a plane that are at a given distance from a given point which is the center.'
According to the given problem,
Radius = 8 inches
Diameter = 16 inches
Considering a pizza is a circle and the area of a circle increases with the square of the radius.
However 45 degrees being less inclined than 30 degrees.
Hence, a slice with a radius of 8 inches, central angle of 45 degrees gives the best value for $ 2 per slice.

Answer:
the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
Step-by-step explanation:
The computation of the amount that he makes last week and in the year 2011 is as follows:
= Sale value of the stocks × earning percentage × number of weeks in a year
= $7,000 × 11% × 52 weeks
= $40,040
hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
We simply applied the above formula so that the correct value could come

Line FG goes through the points (4,9) and (1,3). Which equation represents a line that is perpendicular to FG and passes through the point (2,0)?
-2x+ y=-4
-2x+y=2
X+2y=2
X+2y=4
Answer:
[tex]x + 2y= 2[/tex]
Step-by-step explanation:
Given
Points:
[tex]F = (4,9)[/tex]
[tex]G = (1,3)[/tex]
Required
Determine the equation of line that is perpendicular to the given points and that pass through [tex](2,0)[/tex]
First, we need to determine the slope, m of FG
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex]F = (4,9)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]G = (1,3)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]m = \frac{3 - 9}{1 - 4}[/tex]
[tex]m = \frac{- 6}{- 3}[/tex]
[tex]m =2[/tex]
The question says the line is perpendicular to FG.
Next, we determine the slope (m2) of the perpendicular line using:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{2}[/tex]
The equation of the line is then calculated as:
[tex]y - y_1 = m_2(x - x_1)[/tex]
Where
[tex]m_2 = -\frac{1}{2}[/tex]
[tex](x_1,y_1) = (2,0)[/tex]
[tex]y - 0 = -\frac{1}{2}(x - 2)[/tex]
[tex]y = -\frac{1}{2}(x - 2)[/tex]
[tex]y = -\frac{1}{2}x + 1[/tex]
Multiply through by 2
[tex]2y = -x + 2[/tex]
Add x to both sides
[tex]x + 2y= -x +x+ 2[/tex]
[tex]x + 2y= 2[/tex]
Hence, the line of the equation is [tex]x + 2y= 2[/tex]

Answer:x = -0.1290322581
Step-by-step explanation:
Simplifying
9x + -4(1 + 10x) = 0
9x + (1 * -4 + 10x * -4) = 0
9x + (-4 + -40x) = 0
Reorder the terms:
-4 + 9x + -40x = 0
Combine like terms: 9x + -40x = -31x
-4 + -31x = 0
Solving
-4 + -31x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + -31x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + -31x = 0 + 4
-31x = 0 + 4
Combine like terms: 0 + 4 = 4
-31x = 4
Divide each side by '-31'.
x = -0.1290322581
