The value of x is 77.5. The Triangle Angle Sum Theorem states that the sum of the angles in a triangle is 180°.
What is value?Value is a subjective concept that referred to the word of importance that an individual group of people places on something it is often associated with principal beliefs and standard that are accepted by society when you can be seen as a measure of how important something is true person of organization it is often seen as a reflection of ones worldview and can help to save attitudes decision and behaviors believe is not an absolute and very depending on the context of the looks like commands.
In order to solve for x, we need to use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is 180°. Since angle BAC is bisected by segment AD, the two angles must be equal. Therefore, we can set up the following equation to solve for x:
180° = angle BAC = (x + 7) + (x + 18)
We can solve this equation by combining like terms and isolating the variable x.
180° = 2x + 25
2x = 155
x = 77.5
Therefore, the value of x is 77.5.

A. Mean = 71
B. Median = 75
C. Mode = 0
D. Mean is used to represent data, because mean measures central tendency.
What is mean , median and mode?A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.
We have the Data set: 35, 42, 43, 51, 55, 57, 62, 66, 68, 69, 74, 75, 76, 77, 78, 79 , 82, 84, 86, 88, 93, 94, 101
So, Mean = average
= sum of all numbers / total number of values .
= 1635 / 23
= 71.08
= 71
and, Median = middle term = 12th term = 75
lastly, Mode = Most repeated term or term that has high frequency.
Here no terms are repeating so mode = 0

In the diagram O is the center of the circle if MABC equals 70 what is MAOC 
The measure of ∠AOC of the circle is ∠AOC = 140°
What is Central Angle?The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
r is the radius of the circle
Central Angle = 2 x Angle in other segment
Given data ,
Let the measure of ∠ABC of the circle = 70°
Now , the sides AO and BO are the radius of the circle
where x + y = 70°
So , the measure of ∠AOB = 180 - 2x
And , the measure of ∠COB = 180 - 2y
Now , the measure of ∠AOC = 2 ( x + y )
On simplifying , we get
Central Angle = 2 x Angle in other segment
The measure of angle ∠AOC of the circle is = 2 ( 70 )°
The measure of angle ∠AOC of the circle is = 140°
Hence , the measure of ∠AOC of circle = 140°

Answer: The given expression is:
m² +........+ 1/m²
We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.
Let's try to write the expression in the form of (a + b)²:
(a + b)² = a² + 2ab + b²
If we set a = m and b = 1/m, we get:
(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²
Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.
Therefore, to make the given expression a perfect square, we need to add 2 to it.
So, the term to be inserted is 2.
The expression m² +........+ 1/m² can be written as (m + 1/m)² - 2.

The population of the world grows approximately 1. 1% per year. If the population of the world is approximately 8 billion people in 2022, write an exponential equation to model the world population (in billions) after t years
The population after 5 years will be approximately 8.45 billion.
Determine exponential equationThe exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)^t, where P(t) is the population in billions and t is the number of years after 2022.
To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.
We can use the formula for exponential growth, P(t) = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the number of years.
Substituting the values for P0 and r into the equation, we get:
P(t) = 8(1.011)^t
This equation can be used to find the population after t years.
For example, to find the population after 5 years, we can substitute t = 5 into the equation and get:
P(5) = 8(1.011)^5 ≈ 8.45 billion
Therefore, the population after 5 years will be approximately 8.45 billion.

The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The line y = m(1)x + c is perpendicular to y = x/4 - 2.
This means,
y = (1/4)x - 2 is in the form of y = m(2)x + c
So,
m(1) x m(2) = -1
m(1) = -1 / (1/4)
m(1) = -4
Now,

[tex]1/4 (-4^{3} + 10^{2} )[/tex]=?
Step 2 :
Now, according to the rules, we do the numbers in the brackets first, now, in the brackets, there are indices, so we do those.
Which makes it :
1/4(-64+100)= ?
Step 3 :
Now we add the integers inside the brackets, remember, whenever the equation is like this, it is telling us it is a multiplication, here, it will be 1/4 x (-64+100) . In algebra, we don't use the × sign as it can be misinterpreted as [tex]x[/tex] .
1/4 (-64+100 = 36)
1/4 (36)
=
1/4 x 36
So we have = 1/4 x 36 at last.
Step 4 =
Do the multiplication!
1/4 x 36 = 9
So the answer is 9

There are 2 questions.
Answer:
27) #3 --> 12x - 24 = 60
29) 2x^2 + x - 15
Step-by-step explanation:
27) If x represents the number of boxes, and there are 12 cookies in each box, multiplying 12 by x results in the total number of cookies Kendal bought. However, she kept 2 boxes for herself, which is the same as 2(12) = 24 cookies. Kendal ended up with 60 cookies at the party, so subtracting 24 cookies from the total number of cookies (12x) equals 60 cookies.
29) (3 + x)(2x - 5)
3 * 2x = 6x
3(-5) = -15
x * 2x = 2x^2
x(-5) = -5x
6x - 15 + 2x^2 - 5x =
2x^2 + x - 15
tickets to the play cost $3 for children and $5 dollars for adults. for last bight performance there were 110 people in the audience and they made a total of 450 in ticket sales. how many children and how many adults attended the play (solve by substitution)
Answer:
50 children tickets; 60 adult tickets
Step-by-step explanation:
Let a = number of adult tickets.
Let c = number of children tickets.
a + c = 110
5a + 3c = 450
-3a - 3c = -330
5a + 3c = 450
------------------------
2a = 120
a = 60
a + c = 110
c = 50
Answer: 50 children tickets; 60 adult tickets
