the answer is
It does not make sense to add item on the list because these quantities to be expressed in the same units and the number 100 does not have meaning for the classroom.
Answer:
Step-by-step explanation:
Given the function g(x) = 8x-2, compare and contrast g(-2) and gl4). Choose the statement that is true concerning these two values. O The value of g(-2) is larger than the value of g(4) OThe value of g(-2) is the same as the value of g(4). OThe value of g(-2) is smaller than the value of g(4) OThe values of g(-2) and g(4) cannot be compared.
Given: g(x) = 8x - 2
So, the value of g(-2) = 8 * -2 - 2 = -18
And g(4) = 8 * 4 - 2 = 30
We will check the given statements according to the values of g(-2) and g(4):
1) The value of g(-2) is larger than the value of g(4) [Wrong]
Because the value of g(-2) is smaller then the value of g(4)
2) The value of g(-2) is the same as the value of g(4) [Wrong]
3) The value of g(-2) is smaller than the value of g(4) [True]
4) The values of g(-2) and g(4) cannot be compared. [wrong]
So, the true statement is The value of g(-2) is smaller than the value of g(4)

What is delivery ?
Transporting items from a source point to a predetermined destination is known as delivery. Roads, railroads, shipping lanes, and airline networks all play major roles in the delivery of cargo (physical products). Specialized networks, such as pipelines for liquid products, power grids for electrical power, computer networks like the Internet, or broadcast networks for electronic information, may be used to distribute specific sorts of goods. [1] A specific subcategory is car transport, and an associated variation is autorack, which involves shipping cars through railroad.
Delivery, which comprises both transportation and distribution, is a crucial aspect of trade and commerce.Distribution is the overall process of providing things, while logistics is the study of efficient delivery and disposition procedures for both persons and materials. Distributors are companies that specialize in moving commercial items from their site of manufacture or storage to their point of sale, whereas delivery services are companies that focus on moving goods to consumers. Deliveries of goods for both commercial and private purposes are also made by postal, courier, and moving services.
According to the question
The new refrigerator delivered to his home for $950
tip he gave to the delivery person = $20
let tip he gave to the person in percentage be x
$20= [tex]\frac{x}{100}(950)[/tex]

Answer:
B. A = 6s²

Explanation:
A formula describes a function that is nonlinear if the exponent of the variable is greater than 1.
Therefore, the geometric formulas that describe functions that are nonlinear:

A farmer is telling a rectangle field that is 63 yards long and 60 yards wide what is the distance between opposite corners of the farmers field?
87 yards
Explanations:
Given the following parameters:
• Length of the rectangle = 63 yards
,• Width of the rectangle = 60 yards
The distance between opposite corners of the farmer's field is the diagonal of the rectangle.
To determine the diagonal of the rectangle (d), we will use the Pythagoras theorem:
[tex]\begin{gathered} d^2=l^2+w^2 \\ d^2=63^2+60^2 \\ d^2=3969+3600 \\ d^2=7,569 \\ d=\sqrt[]{7,569} \\ d=87yards \end{gathered}[/tex]Hence the distance between opposite corners of the farmers' field is 87 yards

Given a regular pentagon HIJKL.
We are asked to find the measure of Angle HIK
To find the measure of a central angle of a regular pentagon, we make a circle in the middle of the pentagon. We know that a circle is 360 degrees around.
Now, we will divide the 360 by the five angles. Now, the measure of each central angle is equal to:
360/5
So,
Angle HIK = 360/5
Angle HIK = 72˚
Therefore, the correct option is C, which is 72˚.

[tex]undefined[/tex]Use the point-slope formula to write an equation of the line that passes through (-3, 2) and (-6, -2).Write the answer in slope-intercept form (if possible).
The equation of a line in the slope-intercept form is y = mx + b, where "m" is the slope and b is the y-intercept.
To find the equation of the line given two points (x, y), follow the steps below.
Step 01: Substitute the point (-3, 2) in the equation.
To do it, substitute x by -3 and y by 2.
[tex]\begin{gathered} 2=m\cdot(-3)+b \\ 2=-3m+b \end{gathered}[/tex]Isolate b by adding 3m to both sides of the equation.
[tex]\begin{gathered} 2+3m=-3m+b-3m \\ 2+3m=-3m+3m+b \\ 2+3m=b \end{gathered}[/tex]Step 02: Substitute b in the equation of the line.

[tex]\begin{gathered} y=mx+b \\ y=mx+2+3m \end{gathered}[/tex]Step 03: Substitute the point (-6, -2) in the equation from step 02.
To do it, substitute x by -6 and y by -2.
[tex]\begin{gathered} -2=m\cdot(-6)+2+3m \\ -2=-6m+2+3m \\ -2=-3m+2 \end{gathered}[/tex]Isolate "m" by subtracting 2 from both sides.
[tex]\begin{gathered} -2-2=-3m+2-2 \\ -4=-3m \end{gathered}[/tex]Finally, divide both sides by -3:
[tex]\begin{gathered} \frac{-4}{-3}=\frac{-3}{-3}m \\ \frac{4}{3}=m \end{gathered}[/tex]Knowing "m", use the equation from step 1 to find "b".
Step 04: Find "b".

The measure of angle ∠AOB is 139 degrees, that is the value of m∠AOB is 139.
We are given;
m∠AOC is a straight line = linear pair
m∠AOB = 8x + 51 degree
m∠BOC = 6x - 25 degree
We know that sum of the angles of linear pair is 180 degrees.
So,
∠AOB + ∠BOC = 180 degrees
8x + 51 degree + 6x - 25 degree = 180 degrees
14x = 180 - 26 degrees
x = 154/14 degrees
x = 11 degrees
Therefore,
m∠AOB = 8x + 51 degree = 8 * 11 + 51 degrees = 139 degrees.
m∠BOC = 6x - 25 degree = 6 * 11 - 25 degrees = 41 degrees.
Thus, the measure of angle ∠AOB is 139 degrees, that is the value of m∠AOB is 139.

point (0,6) in which quadrant and axis
Given the point:
(0, 6)
Let's find the quadrant and the axis where the point is located.
We have:
(x, y) ==> (0, 6)
The x-coordinate of the point is 0, while the y-coordinate of the point is 6.
Here, the point (0, 6) lies on the y-axis.
Also, since the x-coordinate is 0, we can say the point lies in between quadrant I and quadrant II.
From the graph above we can see the point (0, 6) is between quadrant I and II, and the point lies on the y-axis.
ANSWER:
• The point is in beween Quadrant I and II
,• The point lies on the y-axis.
Select all the equations on which the point (10,0) lies. O 5x + 2y = 15 O 2x + 4y = 20 O x + y = 10 O 3x + 3y = 13 4x + 2y = 20 O 6x + y = 50
2x + 4y = 20
when y = 0
2x + 4(0) = 20
2x = 10
Divide both-side of the equation by 2
x = 10
Hence, it lies on the point 2x + 4y = 20

(-9,-5),(-6,1) and (5,8)What is the perimeter?
Answer
The perimeter of the triangle is 48.298 units
Explanation
The triangle has the vertices (-9, -5), (-6, 1) and (5, 8).
To find the perimeter of the triangle, we need to find the lengths of the sides of the triangle. The perimeter is the sum of all its sides.
Each side will be calculated from the distance between the vertices.
The distance between two points with the coordinates (x₁, y₁) and (x₂, y₂) is given as
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
The sides of the triangle will be between
(-9, -5) and (-6, 1)
(-9, -5) and (5, 8)
(-6, 1) and (5, 8)
(x₁, y₁) and (x₂, y₂) is (-9, -5) and (-6, 1)
x₁ = -9
y₁ = -5
x₂ = -6
y₂ = 1
d = √[(-6 - (-9))² + (1 - (-5))²]
d = √[(-15)² + (6)²]
d = √(261)
d = 16.155
(x₁, y₁) and (x₂, y₂) is (-9, -5) and (5, 8)
x₁ = -9
y₁ = -5
x₂ = 5
y₂ = 8
d = √[(5 - (-9))² + (8 - (-5))²]
d = √[(14)² + (13)²]
d = √(365)
d = 19.105
(x₁, y₁) and (x₂, y₂) is (-6, 1) and (5, 8)
x₁ = -6
y₁ = 1
x₂ = 5
y₂ = 8
d = √[(5 - (-6))² + (8 - 1)²]
d = √[(11)² + (7)²]
d = √(170)
d = 13.038
The perimeter of the triangle is thus given as
Perimeter = 16.155 + 19.105 + 13.038
= 48.298 units
