Answer:
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
Explain the difference between equilateral and equiangular :)
An equilateral polygon has congruent sides, like a rhombus.
An equiangular polygon has congruent interior angles, like a rectangle.
In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.
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. :)
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

d) The permeter of the recthngle shown is 30 inches
Height is 12 Length is 4x-6
Part A Write & solve an equation to find the vale of x
Equation
Solve and answer
Part B What is the area of the rectangle?
Answer:
Step-by-step explanation:
P = 2(w + l)
A = lw
~~~~~~~~~~~~~
Part A:
2[(4x - 6) + 12] = 36
8x- 12 + 24 = 36
8x = 36 - 12
x = 3
Part B:
A = 6 × 12 = 72 inch.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.
Hope this helped!
Which set of ordered pairs does not represent a function? { ( − 3 , − 1 ) , ( 8 , − 1 ) , ( 0 , − 5 ) , ( − 9 , − 2 ) } {(−3,−1),(8,−1),(0,−5),(−9,−2)} { ( 5 , 9 ) , ( − 3 , − 5 ) , ( 0 , 4 ) , ( − 9 , 9 ) } {(5,9),(−3,−5),(0,4),(−9,9)} { ( 9 , 0 ) , ( − 5 , 4 ) , ( 5 , 0 ) , ( 6 , 3 ) } {(9,0),(−5,4),(5,0),(6,3)} { ( 2 , 8 ) , ( 2 , 1 ) , ( − 9 , − 5 ) , ( − 8 , 9 ) } {(2,8),(2,1),(−9,−5),(−8,9)} Submit Answer
Answer:
[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]
