The value of n in the given triangle is 11.
What is incenter of a triangle?The incenter is one of the triangle's points of concurrency formed by the intersection of the triangle's 3 angle bisectors.
Given that, triangle DEF, where A is the incenter of the triangle, we need to find the value of n,
Since we know that, incenter is a point in triangle where all the angle bisector meets, therefore,
3n-6 = 27
3n = 33
n = 11
Hence, the value of n in the given triangle is 11.

"substitute in" x - 3 for y in the top equation.
Why is this useful for finding our first solution?
x + y = 11
y = x - 3
Answer:
because in the bottom eqution it shows us x-3=y therefor we could re-write the top equation as x+x-3=11
Tim is reading a book. On Monday he reads 2 pages. On each day after that, he reads triple the number of pages as the previous day. How many pages did Tim read on Thursday?
Answer:
Tim read 54 pages on Thursday.
Step-by-step explanation:
Consider the provided information.
Tim read 2 pages on Monday. Each day after that, he reads triple the number of pages as the previous day.
Monday = [tex]2=2[/tex]
Tuesday = [tex]2\times 3=6[/tex]
Wednesday = [tex]2\times 3\times 3=18[/tex]
Thursday = [tex]2\times 3\times 3\times 3=54[/tex]
Hence, Tim read 54 pages on Thursday.
How many pages does Tim read on Monday? 2 pages.
If Tim tripled the amount that he read on Monday, how many pages did he read on Tuesday? 2 × 3 = 6 Pages
Repeat for Wednesday. 6 × 3 = 18 Pages
Repeat for Thursday. 18 × 3 = 54 Pages

Is Noah's work correct? Explain. Yes, Noah's calculations are correct. No, Noah did not simplify correctly. No, Noah used the diameter instead of the radius in the calculations. No, Noah did not use the correct formula for volume of a sphere.
Answer:
No, Noah used the diameter instead of the radius in the calculations.
V = 91.13π
Step-by-step explanation:
Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.
V = πr3
V = π(9)3
V = π(729)
V = 972π cubic units
Is Noah’s work correct
Volume of a sphere, V = πr³
radius, r = diameter / 2
Diameter = 9 units
r = 9 / 2
= 4.5 units
Volume of a sphere, V = πr³
= π × 4.5³
= π × 91.125
= 91.125π
Approximately 91.13π
V = 91.13π
No, Noah used the diameter instead of the radius in the calculations.
Answer:
no, he used radius instead of diameter

tan(A/2)
tan(A/2)=sinA/1+cos A
tan(A/2)= 5/13÷1+12/13
tanA/2=1/5
Answer:
tan([tex]\frac{A}{2}[/tex] ) = ± [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Using the trigonometric identity
tan ([tex]\frac{A}{2}[/tex] ) = ± [tex]\sqrt{\frac{1-cosA}{1+cosA} }[/tex]
Given
tanA = [tex]\frac{5}{12}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle 5- 12- 13 ( with hypotenuse 13 ), then
cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex] , then
tan ([tex]\frac{A}{2}[/tex] )
= ± [tex]\sqrt{\frac{1-\frac{12}{13} }{1+\frac{12}{13} } }[/tex]
= ± [tex]\sqrt{\frac{\frac{1}{13} }{\frac{25}{13} } }[/tex]
= ± [tex]\sqrt{\frac{1}{25} }[/tex]
= ± [tex]\frac{1}{5}[/tex]

Which graph shows a line with the slope of 3/2?
Answer:
B.
Step-by-step explanation:
slope = Rise (y difference) / Run (x difference)
B, Rise = 3 run = 2 slope = 3/2
The graph with a line of slope 3/2 is graph B.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Slope of a line with two points (x, y) and (x', y') on the lines is,
Slope = (y' - y) / (x' - x)
Take any two points from all the three graphs given to find the slope.
A. Two points are (0, 4) and (6, 8)
Slope = (8 - 4) / (6 - 0) = 4 / 6 = 2/3
B. Two points are (0, 0) and (4, 6)
Slope = (6 - 0) / (4 - 0) = 6/4 = 3/2
C. Two points are (0, 2) and (2, 8)
Slope = (8 - 2) / (2 - 0) = 6/2 = 3
Hence the graph B has slope equals 3/2.

A model village is built to scale.
It has a scale of 1 : 19.
A road has a real-life length of 1.14 km.
What is the length of the road in the model village in m?
Answer:
The length of the road in the model is 60 m.
Step-by-step explanation:
Given: scale = 1:19
real-life length of the road = 1.14 km
= 1140 m
Let the length of the road in the model be represented by d. A scale is a representative fraction that can be used to either increase or decrease the length of an object.
Scale = [tex]\frac{length on drawing}{actual length}[/tex]
The actual length is the real-life length given as 1140 m.
So that,
[tex]\frac{1}{19}[/tex] = [tex]\frac{d}{1140}[/tex]
19d = 1140
⇒ d = [tex]\frac{1140}{19}[/tex]
= 60
Therefore, the length of the road in the model is 60 m.

Determine what shape is formed for the given coordinates for ABCD, and then find the perimeter and area as an exact value and rounded to the nearest tenth.
A (−9, 3), B (−6, −1), C (2, 5), D (−5, 6)
Answer:
Perimeter = 5 + 5 + 7.1 + 10 =27.1
area = (5 + 10)x5 / 2 = 37.5
Step-by-step explanation:
Slope formula: m = (x' - x)/(y' - y)
m-AD: (6-3)/(-5 - -9) = 3/4 (I'm not detail other Other slopes)
m- BC = 3/4
m-AB = - 4/3
m-AD = m-BC AD // BC (ABCD is a Trapezoid)
m-AB = - 1 / m-BC
AB ⊥ BC
segment length formula: d = √(x' - x)² + (y' - y)²
AD = √(-5 - -9)² + (6 - 3)² = √4² + 3² = √25 = 5
DC = √50 = 7.1
BC = √100 = 10
AB = √25 = 5
Perimeter = 5 + 5 + 7.1 + 10 =27.1
area = (5 + 10)x5 / 2 = 37.5
area ABCD = (5+10)x5 / 2 =

The length of a rectangle is represented by 4a+3b and its width is represented by 3a-2b. Enter the polynomial for the perimeter of the rectangle. What is the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number?
Answer:
a) The polynomial for the perimeter of the rectangle is = 14a - 2b
b) 150
Step-by-step explanation:
a) The formula for the area of a rectangle is given as:
P = 2L + 2W
From the question:
The length of a rectangle = 4a+3b
The width of a rectangle = 3a-2b.
The Perimeter of the rectangle is
Perimeter = 2(4a + 3b) + 2(3a - 2b)
Perimeter = 8a + 6b + 6a - 4b
Perimeter = 8a + 6a + 6b - 4b
Perimeter = 14a - 2b
Hence:
The polynomial for the perimeter of the rectangle is = 14a - 2b
b) What is the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number?
Non-zero whole number are single digit number such as: 1, 2, 3, 4, 5, 6, 7, 8, 9
The perimeter of the rectangle is = 14a - 2b
We are asked to find the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number.
In order to solve this, we would used the highest non zero whole number which is 9
Hence,
For a = 12 , b = 9
14 × 12 - 2(9)
= 168 - 18
= 150
Hence, the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number is 150
