Answer:
A. Point H is the center of the circle that passes through points D, E, and F.
C. Line segment H E is-congruent-to line segment H D
Step-by-step explanation:
The center of a circle is a point within it that has the same distance to all other points on its circumference.
Constructing a circle with center H would pass through the points D, E and F at the three vertices of the given triangle. Thus producing a circumscribed circle to the triangle. A circumscribed circle is one that can is constructed outside a given figure.
It can also be observed that, DH ≅ EH ≅ FH. So that, the line segment HE is congruent to line segment HD.
The correct options in the given question are: A and C.
Answer:
A. Point H is the center of the circle that passes through points D, E, and F
C. HC≈HD

48 people attended the Sunday matinee to watch a film. .Three over 8 of the people went to see a romantic comedy. .One over six of the people went to see an action movie. .The remaining people saw a horror movie. How many people saw a horror movie?
Answer:
22 people saw an horror movie
Step-by-step explanation:
Total people who attended the Sunday matinee = 48
People who saw romantic comedy = 3/8 of 48
= 3/8 × 48
= (3*48) / 8
= 144 / 8
= 18 people
People who saw action movie = 1/6 of 48
= 1/6 × 48
= 48/6
= 8 people
People who saw horror movie = x
Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie
48 = 18 + 8 + x
48 = 26 + x
Subtract 26 from both sides
48 - 26 = 26 - 26 + x
22 = x
x = 22 people
22 people saw an horror movie

Step-by-step explanation:
by the definition of supplementary angles, the base angles of the top isosceles triangle have the measure of
Answer:
128
Step-by-step explanation:
Top Triangle
Let the base angles of the top triangle = y
y + 102 = 180
y = 78
The vertex
Is found by adding the two base angles together and subtract that from 180
y + y + vertex = 180
78 + 78 + vertex = 180
156 + vertex = 180
vertex = 180 - 156
vertex = 24 degrees
Bottom Triangle
Because the base angles are connected by a vertically opposite angle on the bottom triangle, both base angles are 26
Therefore 26 + 26 + x = 180
52 + x = 180
x = 180 - 52
x = 128
Ten years ago, the population at Lincoln High School was about 2,000 students. Since then, the population has increased by 25%.
What is the new population now?
Answer:
2,500 students
Step-by-step explanation:
If the population has increased by 25%, the total population of the school is now 125% of what it used to be. Then to figure it out, you find out 125% of 2000 which is 2,500 students!

An Auditorium has 29 rows, with 115 chairs in each rows. How many chairs does the auditorium have in all? Show your work
Answer:
3335 chairs
Step-by-step explanation:
To find the total number of chairs, multiply 29 by 115, since there are 29 rows that have 115 chairs:
29(115)
= 3335
So, the auditorium has 3335 chairs in all
Answer: 3335 Chairs
Work: So, the question already gave us how many seats are there per row, now we need to find out how many are there in 29 rows. You multiply 115 by 29 to find out how many seats are there, and you get 3335 chairs. I hope this helps you, and stay safe. :)

[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex] is not a function
Step-by-step explanation:
Given
[tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
[tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
[tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
Required
Which is not a function
A function is of the form [tex](x,y)[/tex]
Assume a function is:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}[/tex]
In simple terms:
For an ordered pair to be regarded as a function, no x value must be repeated
Analyzing the options:
1. [tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once
2. [tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
This is a function because none of the x values (5, -3, 0 and -9) appeared more than once
3. [tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
This is a function because none of the x values (9, -5, 5 and 6) appeared more than once
4. [tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
This is not a function because one of the x values (2) appeared more than once.
i.e.
[tex](2,8)[/tex] and [tex](2,1)[/tex]

Answer:
equation 1
y = -2x
equation 2
y = x-3
Solution to both
(1,-2)
Step-by-step explanation:
We need to get the equations of both lines
General form is;
y = mx + c
where m is slope and c is the y-intercept
Table 1
since we have a point 0,0; the y-intercept here is zero
Let us get the slope. We can do this by selecting any two points
m = (y2-y1)/(x2-x1)
m = (2-10)/(-1+5) = -8/4 = -2
So the equation of the first line is;
y = -2x
Table 2
we get the slope
m = (4+2)/(7-1) = 6/6 = 1
The partial equation is;
y = x + c
To get c, we select any two point and substitute
4 = 7 + c
c = 4-7
c = -3
So the equation is;
y = x-3
To get the solution to both systems, we equate the y
-2x = x - 3
-2x-x = -3
-3x = -3
x = -3/-3
x = 1
To get y, we substitute;
recall; y = -2x
y = -2(1)
y = -2
Solution to the system is;
(1,-2)

A racing car travels at a speed of 193 miles per hour.
Work out an estimate for the number of seconds the racing car travels in 10 miles.
Answer:
The estimate is 186.5 seconds.
Step-by-step explanation:
To calculate the estimate of the time the racing car will take to travel 10 miles, we have to first find the ratio of the original distance to the requested distance.
The number of seconds in an hour is [tex]60 \cdot 60[/tex] seconds, which equals to 3600 seconds.
[tex]\frac{193}{10} = \frac{3600}{x}[/tex]
[tex]19.3 = \frac{3600}{x}[/tex]
[tex]x = \frac{3600}{19.3}[/tex]
[tex]x \approx 186.5[/tex]
Hence, the estimate is 186.5 seconds.
