The equation x + (60 + 70)° = 180° is used to solve for the measure of the vertical angle x = 50°
What are vertically opposite anglesVertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.
The angle y and x form vertical angles, so x = y
Angle y form a straight line with 60° and 70° so we have the equation to solve for x as:
x + 60° + 70° = 180° {sum of angles on a straight line}
x + 130° = 180°
x = 180° - 130° {subtract 139° from both sides}
x = 50°
Therefore, the measure of the vertical angle x is equal to 50° derived with the equation x + (60° + 70°) = 180°.

How to find translation vector?To find the translation vector that maps quadrilateral ABCD to quadrilateral $A"B"C"D"$, we can subtract the coordinates of corresponding vertices. Let $\mathbf{t}$ be the translation vector. Then:

Similarly, we have:
[tex]$$ \begin{align*}\mathbf{B}" - \mathbf{B} &= \langle 0 - t_x, -1 - t_y \rangle - \langle 0, -2 \rangle \\\&= \langle -t_x, 1 - t_y \rangle \\\\\\mathbf{C}" - \mathbf{C} &= \langle 1 - t_x, -3 - t_y \rangle - \langle 1, 0 \rangle \\\&= \langle -t_x, -3 - t_y \rangle\end{align*}[/tex]Since [tex]$\mathbf{D}"$[/tex] is not given, we cannot use it to solve for the components of [tex]$\mathbf{t}$[/tex]. However, note that the x-coordinate of [tex]$\mathbf{A}"$[/tex] is -3, which is 3 less than the x-coordinate of [tex]$\mathbf{A}$[/tex]. This suggests that the translation vector [tex]$\mathbf{t}$[/tex] has a component of 3 in the x-direction. Similarly, the y-coordinate of [tex]$\mathbf{B}"$[/tex] is -1, which is 1 more than the y-coordinate of [tex]$\mathbf{B}$[/tex]. This suggests that the translation vector [tex]$\mathbf{t}$[/tex] has a component of -1 in the y-direction. Therefore, we have:

From the given data you can find the slope by solving the system linear equation.
For example, you can write a system linear equation from the points: (1,-2) and (4,7).
-2=m+b (1)
7=4m+b (2)
Multiplying equation 1 by -1, you have
2= -m -b (1)
7= 4m+b (2)
Summing the previous equation, you can find the slope (m):
9=3m
m= 9/3
m= 3
If m=3, from equation 2, you can find the coefficient b.
7 = 4m + b
7 = 4*3 +b
7=12 + b

Broderick has $420 in his checking account. He made 6 deposits of 35. 50 each. He needs to write 6 checks for 310. 75 each
Broderick needs $610.00 in his account to cover his checks.
We know that the balance Boderick has is $420.
First, we will calculate the total amount of the 6 deposits made by Broderick each of $35.50 deposit as follows -
$35.50 x 6 = $213.00
Hence, the total amount of the 6 deposits made by Broderick is $213.00
Next, we will calculate the total amount of the 4 checks he needs to write-
$310.75 x 4 = $1243.00
Hence, the total amount of the 4 checks that Broderick needs to write is $1243.00
Now we will find the final balance of Broderick's account after all the deposits and check withdrawals. We can do this by adding the total amount of the deposits to his initial balance and subtracting the total amount of the checks as follows-
$420.00 + $213.00 - $1243.00 = -$610.00

We would need to add 8 more sets of 3 candies to 23 candies in order to have the same amount as Casey.
To find this, we can divide the total amount of candy Johnny has (23) by the amount of candy Casey has (3) and round up to the nearest whole number:
(23) / (3) = 7.666...
Since we can't have a fraction of a set of candies, we must round up to the nearest whole number, which is 8.

Which are solutions of the equation 4x2 – 7x = 3x + 24? Check all that apply
Answer:
x=5/2 and x=0
Step-by-step explanation:
To solve this equation, we first need to get all the terms on one side of the equation by subtracting 3x from both sides:
4x^2 - 7x - 3x = 24
Simplifying, we get:
4x^2 - 10x = 24
Now, we can factor out the GCF (Greatest common factor) on the left side of the equation:
2x(2x-5) = 24
Now we can divide both sides of the equation by 2x(2x-5) to get the solutions for x:
x = 5/2 , x = 0
So the solutions of the equation 4x^2 - 7x = 3x + 24 are x=5/2 and x=0

Given: ∆KLM, KL = LM m∠K = 17°, R = 1. 08 Find: KM
triangle is inside a circle with a midpoint O
From the triangle KLM inside the circle, the value of KM is calculated. And, the value is 1.2079.
A triangle is a polygon made up of three vertices, three angles, and three sides. First, draw a circle with a midpoint represented by O. Then, draw a triangle KLM inside a circle. Now, construct the line segments KO, MO, and LO because they form the circle's radius.
Given that KL = LM. Since two sides of the triangle KLM is equal, it is an isosceles triangle. Also, ∠K=∠M=17°. The total angle of this triangle is 180°. Then, ∠L=180°-17°-17°=146°.
Half the angle L is 73°. Then, ∠KLO=∠MLO=73°.
Consider triangle KLO, this triangle is also isosceles because KO = LO. Then, ∠KLO=∠OKL=73°.
Now, ∠KOL is calculated as follows from the triangle KLO,
[tex]\begin{aligned}\angle KOL&=180^{\circ}-73^{\circ}-73^{\circ}\\&=34^{\circ}\end{aligned}[/tex]
Similarly, consider triangle MLO, this triangle is also isosceles because LO=MO. Then, ∠MLO=∠OML=73°.
Now, ∠LOM is calculated as follows from the triangle MLO,
[tex]\begin{aligned}\angle LOM&=180^{\circ}-73^{\circ}-73^{\circ}\\&=34^{\circ}\end{aligned}[/tex]
Then,
[tex]\begin{aligned}\angle KOM&=\angle KOL+\angle LOM\\&=34^{\circ}+34^{\circ}\\&=68^{\circ}\end{aligned}[/tex]
Using, the cosine law of the triangle KOM, we get,
[tex]\begin{aligned}(KM)^2&=1.08^2+1.08^2-2(1.08)(1.08)\cos 68^{\circ}\\&=2.3328-2.3328(\cos 68^{\circ})\\&=2.3328(1-\cos 68^{\circ})\\&=2.3328(0.6254)\\&=1.4589\\KM&=\sqrt{1.4589}\\&=1.2079\end{aligned}[/tex]

How to evaluate decimal number digits?When we are talking about decimals, the left hand side before the decimal are referred to as whole numbers while the first digit after the decimal represents the tenths place, the next digit after the tenths place represents the hundredths place, the next digit after the hundredths place represents the thousandths place and so on.
Now, we are given two decimals 0.6 and 0.39.
We see clearly that 0.6 has a greater tenths digit than the hundredths digit in 0.39. This is seen as;
0.6 = 6/10 while 0.39 = 39/100

At a large museum, there are 60 people in each tour group. so that the ordered pairs are 1 - 60 peoples, 2 - 120 peoples, 3 - 180 peoples, 4 - 240 peoples, 5 - 300 peoples, 6 - 360 peoples etc.
What is the ordered pairs?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
In order to understand a point visually, it can be helpful to position it on the Cartesian plane.
An ordered pair's numerical values may be fractions or integers.
Given that, at a large museum, there are 60 people in each tour group.
In 1 group there are 60 peoples.
In 2 group there are 2 * 60 = 120 peoples.
In 3 group there are 3 * 60 = 180 peoples.
like this the correct ordered pairs are 1 - 60 peoples, 2 - 120 peoples, 3 - 180 peoples, 4 - 240 peoples, 5 - 300 peoples, 6 - 360 peoples etc.

Given that a function, g, has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18 and that g(-1) = 2 and g(2) = 8, select the statement that could be true for g.
The only option that is true for the function g is; Option D: g(3) = 18
How to interpret the domain and range of a function?The function, g, has;
Domain; -1 ≤ x ≤ 4
Range: 0 ≤ g(x) ≤ 18
g(-1) = 2 and g(2) = 8
Then the following properties must hold to be true;
The value(s) of x must be between -1 and 4
The values of g(x) must be between 0 and 18.
We consider the options and state why they are true or otherwise.
Option A: g(5) = 12
When x = 5, g(5) = 12. This contradicts property 1 stated above and as such it is not true.
Option B: g(1) = -2
When x = 1, g(x) = -2. This contradicts property 2 stated above and as such, it is not true.
Option C: g(2) = 4
When x = 2, g(2) = 4. However by property 4 stated above, g(2)=9. Therefore, we can say that it is not true.
Option D: g(3) = 18
When x =3 means that its domain lies between -1 and 4 and its range lies between 0 and 18.
Therefore, Option D is true.

The line y = -3/2(x) + 3 has a slope of negative three halves and a y-intercept of 3.
The correct option is C.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
We have a graph that has a slope of negative three halves and a y-intercept of 3.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂),
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁).
A). Line passing through the points (0, 2) and (3, 0).
y - 2 = 2/3(x)
y = 2/3(x) + 2.
This is not a required line.
B). Line passing through the points (0, 2) and (2, -1).
y - 2 = -3/2(x)
y = -3/2(x) + 2.
This is not a required line.
C). Line passing through the points (0, 3) and (2, 0).
y - 3 = -3/2(x)
y = -3/2(x) + 3.
This is a required line.
D). Line passing through the points (0, 3) and (3, 1).
y - 3 = -2/3(x)
y = -2/3(x) + 3.
This is not a required line.
Therefore, y = -3/2(x) + 3 is a required line.

a survey among tenants of shared apartments asked each tenant what percentage of the cleaning around the apartment he or she does. the survey found that aggregating the percentages for each apartment produces an average of much more than 100%. this result may be due to what bias?
The result of an average of more than 100% in a survey of tenants on cleaning chores in shared apartments is likely due to social desirability bias.
The average tenant response of more than 100% in a study about cleaning duties in shared apartments is probably the product of social desirability bias. Social desirability bias occurs when respondents give answers that they think are socially acceptable or desirable, rather than their true opinions or behavior.
In this case, tenants may have overstated their contribution to cleaning the apartment, in order to appear more helpful or responsible, leading to an average percentage higher than 100%.
