Option C) is correct......
In AABC, m ZA=36° and m ZB =92°. What is M
?
m∠C = 52°
The total interior angle of a triangle sum ups to 180°Solve:
m∠A + m∠B + m∠C = 180°
36° + 92° + m∠C = 180°
m∠C = 180° - 92° - 36°
m∠C = 52°
Answer:
m∠C = 52°Step-by-step explanation:
Angle Sum Property
∠A + ∠B + ∠C = 180°Here we have :
∠A = 36°∠B = 92°Solving :
36° + 92° + ∠C = 180°∠C + 128° = 180°∠C = 52°an eqaution is shown 6x-3=3x+12 solve for x
Answer:
x=5
Step-by-step explanation:
6x-3=3x+12. Subtract 3x from both sides.
3x-3+12. Add 3 to both sides.
3x=15. Divide 3 from both sides.
x=5

which correctly gives the slope and y-intercept of the line represented by the equation below x-y=2
Answer:
y int = -2
slope = 1
Step-by-step explanation:
x-y=2
-y=-x+2
y=x-2
y int = -2
slope = 1
Answer:
Slope = 1
Y-intercept = -2
Step-by-step explanation:
First, we will put it into slope-intercept form.
x - y = 2
x = y + 2
y = x - 2
This gives us the slope of one and the y-intercept being -2.
Check attachments for more information on slope-intercept form as well as the line graphed.
What is the range and domain!!
PLEASE HELP I WILL GIVE OUT MORE POINTS AND MARK BRAINIST ONLY IF YOU RIGHT I DO CHECK IT BUT PLEASE AND THANK YOU
Answer:
Domain: 0 ≤ x ≤ 50
Range: 0 ≤ y ≤ 100
Step-by-step explanation:
Information
Domain: set of all possible input values (x-values)
Range: set of all possible output values (y-values)
Closed circle: less than or equal to and greater than or equal to (≤ or ≥)
Open circle: less than or greater than (< or >)
Domain
From inspection of the diagram:
minimum value of x = 0maximum value of x = 50Closed circle at the beginning and end of the lineTherefore, the domain is: 0 ≤ x ≤ 50
Range
From inspection of the diagram:
minimum value of y = 0maximum value of y = 100Closed circle at the beginning and end of the lineTherefore, the range is: 0 ≤ y ≤ 100

Answer:
(2,-3) and (49/29, -108/29)
Step-by-step explanation: Assuming this is an exam and time is limited, first you gotta sketch the circle for clarity. Using the standard circle equation
(x-a)^2 + (y-b)^2 = r^2
(x-1)^2 + (y+3)^2 =1
You can always expand to verify it gives x^2 + y^2 - 2x + 6y + 9=0
Now you know (a,b) which is also the center of the circle being= (1,-3) and the radius(r) = 1
Your first assumption here even without drawing the circle is that it has to be in the fourth quadrant meaning all values of x for any point of intersection on that circle has to be +ve. Looking at your answer choices only c with is (2,-3) and (49/29, -108/29) fulfills this hence it is your answer.
Also you have to realize point (2,-3) on the straight line has same y coordinates with center of this circle.
Tell whether the triangle with the given side lengths is a right triangle
14mm, 19mm, 23mm
Answer:
not a right triangle
Step-by-step explanation:
The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:
c² = a² +b²
23² = 14² +19²
529 = 196 +361
529 = 557 . . . . . . . . not true; not a right triangle
__
The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.

What is the surface area?
Answer:
130 in^2.
Step-by-step explanation:
It has 8 faces
Surface area = 4*2 + 1*2 + 3*2 + 5*2 + 7*2 + 6*2 + 6*7-3 + 6*7-3
= 8+2+6+10+14+12+39+39
= 130 in^2.
Consider the line 2x+6y= -4. What is the slope of a line perpendicular to this line? What is the slope of a line parallel to this line?
Answer:
the slope of the line perpendicular to that line is 6/2
Step-by-step explanation:
Find the slope of the original equation by putting it into y=mx + b form
2x+6y=-4 Given
2x-(2x)+6y=-4-(2x) Subtract 2x from both sides
6y= -2x -4 Simplify
6y/6= -2x/6 -4/6 Divide both sides by 6
y= -2/6 x - 4/6 Simplify
*perpendicular slopes are opposite reciprocals*
-2/6 = slope
2/6 is the opposite of -2/6
6/2 is reciprocal of 2/6
The table below shows the number of people in a spinning class each day last week.
What is the mean number of people in a class?
Based on the information provided, the mean number of people in a class is 21 people.
How to calculate the mean number of people?To calculate the mean number, the general formula is the total of people in the class/ number of classes.
Then, let's find the total of people in classes by adding the number of people that are in class every day:
13+23+24+31+14 = 105 people in total
Number of classes: 5 classes or 5 days
The mean number of people in a class: Divide the total of people by the number of classes
105 / 5 = 21 people per class in average

Question
Find the surface area of the regular pyramid.
Answer:
Surface area:The sum of all the sides to a figure.Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.
Formula for area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.
Plug in what we know:-
A = BH x 1/2
A = 16(20) x 1/2
A = 320 x 1/2
A = 320/2
A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;
160(5)
= 800 mm is the area of all the triangles.
Now add the base area to the area of all the triangles.
440.4 + 800
= 1,240.4 mm.
Therefore the surface area of this pyramid is 1,240.4 mm.
Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
A = 1/2 x base x slant height
For the 5 triangles,
A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height
Substitute values,
A = 5 x 1/2 x 16mm x 20mm = 800 mm²
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²

If the spinner below is spun twice, find the probability that it lands on N, then a vowel.
Answer:
0.29 or 29%
Step-by-step explanation:
There are 7 options per spin. Of which 3 vowels.
For 2 spins, total spins is 14.
conditions:
First spin is 1/7
Second spin is 3/7
so,
4/14 = 0.29 or 29% I think
