Find the sum of the angle measures in a regular polygon.
A) 720*
B) 900*
C) 1080*
D) 1260*
Please help!! Thanks
Answers
Answer:
D) 1260°
Step-by-step explanation:
In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.
Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°
You can easily confirm that it works for triangles and quadrangles ;)
The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°
1260°
hope this helps ^-^

In a room, there are four chairs. The first chair is towards North, the third chair is towards south, the second chair is towards east and fourth chair is towards west. If the distance between any two consecutive chairs is equal and all the interior angles are 90° each, then which of the following shape is formed?
A) Square
B) Rectangle
C) Trapezium
D) Circle
Answers
Answer:
The correct answer is A. The shape formed by the four chairs is a square.
Step-by-step explanation:
A square is a figure whose 4 sides are exactly equal in length, and whose 4 interior angles are equal to 90 degrees each. Thus, if the distance between the chairs is exactly the same between them, it is understood that the "sides" of the figure are all the same. Thus, if all the internal angles of the figure are 90º, the figure that the chairs form is a square.

which three fractions are less than 40%
A. 3/20
B. 23/100
C. 3/5
D. 1/8
Answers
Answer:
A, B, D
Step-by-step explanation:
Answer:
A, B, D
Step-by-step explanation:
40% is the same as the fraction 4/10.
Compare 4/10 with 3/20 (A):
LCM of 10 and 20 is 20, so make the denominators of all fractions to 20
We now have 8/20 and 3/20
Now you can just simply look at the numerators. 3 is obviously less than 8 so option A is less than 40%
Compare 4/10 with 23/100 (A):
LCM of 10 and 100 is 100, so make all denominators 100
Now compare 40/100 and 23/100
40>23 so 23/100 is less than 40%
Compare 4/10 with 3/5 (C):
We can further reduce 4/10 to 2/5, and conveniently it has the same denoninator as 3/5. 3 is NOT less than 2, so C is ruled out.
Compare 4/10 with 1/8 (D):
LCM of 10 and 8 is 40, so we'll use that as our denominator
We now have 16/40 and 5/40.
5 is less than 16, so we include D in our answer.

Answers
Answer:
A
Step-by-step explanation:
As the price goes up per dollar there is a definite decrease in sales. Specifically, about 5 shirts don't get sold per increase of one dollar.
The correct option is A. for every one dollar price increase of T- shirt, 5 fewer T-shirts were sold.
What is a scatter plot?A scatter plot is a type of data visualization that shows the relationship between different variables. This data is shown by placing various data points between an x- and y-axis. Essentially, each of these data points looks “scattered” around the graph,
Given equation of line for that fits best for scattered data is y -5x + 80
From the graph it is clear that as the slope of the given equation is decreasing one
y -5x + 80 =0
y ∝ -mx
(no. of T-shirts sold) ∝ (-5) × (price of a T-shirt)
So, as the price of the T-shirt increases the less T-shirt were sold.

Answer:
KL = 23
KM = 29
Step-by-step explanation:
By applying cosine rule in the given triangle KLM,
cos(∠M) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(52°) = [tex]\frac{LM}{KM}[/tex]
cos(52°) = [tex]\frac{18}{KM}[/tex]
KM = [tex]\frac{18}{\text{cos}52}[/tex]
KM = 29.24
KM ≈ 29
By applying sine rule,
sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(52°) = [tex]\frac{KL}{29.24}[/tex]
KL = 29.24[sin(52°)]
= 23.03
≈ 23
KL = 23

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
From the graph,
The y coordinate values are the range of the function.
