The table with the situations that represent or not proportional relationships of distance and time is given at the end of the answer.
Which situation models a proportional relationship?A situation represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:
y = kx.
One example, in the context of this problem, is the relation between velocity, distance and time, as velocity is distance divided by time, hence:
v = d/t.
The relation between distance and time is given as follows:
distance = velocity x time
distance = v x t.
Hence it will only be proportional if the velocity is constant, that is, if the acceleration is of zero.
Examples of non-proportional situations in the context of this problem are:
A touchdown, as when the play starts the player is stopped then he accelerates and the velocity is not constant.The horse running around the race track, same logic, different velocities.The distance and time table (4 - 15, 8 - 30, 12 - 45) does not show enough information, we need to know if the initial point was of (0,0).
What is the missing information?The objects are missing, and have been dragged to their correct situation on the table.

The angles that are supplementary angles are: ∠SRT and ∠SRO
What are Supplementary Angles?Angles that are supplementary will give us a sum of 180 degrees when we add the two angles together. One is the supplement of the other.
Some examples of angles that are supplementary angles that are formed when two parallel lines are intersected by a transversal include:
Same-side interior anglesSame-side exterior anglesLinear pair angles formed on a straight line and are adjacent to each other.Angle SRT and angle SRO are angles that are adjacent to each other because they share a common side SR and a common vertex R. They line on the straight line OT.
Therefore, angle SRT and angle SRO are two angles that are supplementary angles as shown in the diagram attached below where lines NP and QS are parallel lines. The supplementary angles are therefore angle SRT and angle SRO.

Which term of the arithmetic sequence 7, 3, -1, -5, ... is -385?
99th term of the given arithmetic sequence 7, 3, -1, -5, ... is -385.
We are provided with the arithmetic sequence mentioned below;
7, 3, -1, -5, ................. -385
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n−1)d
where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.
With the help of provided arithmetic sequence we can write;
[tex]a_{n}[/tex] = -385
[tex]a_{1}[/tex] = 7
d = difference between a term and its previous term = 3 - 7 = -4
Put these values in equation 1 , we will get
-385 = 7 + (n-1) (-4)
392 = 4n -4
4n = 396
n = 99
So we can conclude that the 99th term of the arithmetic sequence 7, 3, -1, -5, ... is -385.

Grayce has three diamonds that weigh 0.275 g each. Morgan has two diamonds that weigh 0.412 g each. Who has more grams of diamonds?
Grayce has 0.825 g of diamonds and Morgan has 0.824 g of diamonds. Grayce has more grams of diamonds
Calculating weightsFrom the question, we are to determine the person that has more grams of diamonds
From the given information,
"Grayce has three diamonds that weigh 0.275 g each"
and
"Morgan has two diamonds that weigh 0.412 g each"
Thus,
The total mass of Grayce's diamonds is 3 × 0.275 g
3 × 0.275 g = 0.825 g
Also,
The total mass of Morgan's diamonds is 2 × 0.412 g
2 × 0.412 g = 0.824 g
Since 0.825 is greater than 0.824,
Then,
Grayce has more grams of diamonds.

Answer: c
Step-by-step explanation:
The solution set for the inequality is p > -9.4. See attachment below for the graph.
How to Graph the Solution Set for an Inequality?An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.
An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.
Given the inequality, p + 3.6 > −5.8, solve for p:
p + 3.6 > −5.8
Subtract 3.6 from both sides
p + 3.6 - 3.6 > -5.8 - 3.6
p > -9.4
Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.

a farmer is building a fence to enclose a rectangular area consisting of 2 separate regions. the 4 walls and one additional vertical segment to separate the regions are made up of fencing. if the farmer has 648 feet of fencing what are the dimensions of the region which enclose the maximum area?
The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:
x + x + y + y + x = 648
3x + 2y = 648
y = 324 - 1.5x
Area (A) = xy
A = xy
A = x(324 - 1.5x)
A = 324x - 1.5x²
The maximum area is at A' = 0, hence:
A' = 324 - 3x
324 - 3x = 0
3x = 324
x = 108 feet
y = 324 - 1.5(108) = 162 feet

Using the figure below, Maggie used the definition of vertical angles to help her solve for x. Since vertical angles are congruent, she set the two given expressions equal to each other. After solving for x, her teacher said she got the wrong value for x. Explain where Maggie made her mistake when solving for x.
Using vertical angles, Maggie made her mistake when combining the like terms of x, which has a result of -3x and not 3x, hence the correct result is of x = 9.
What are vertical angles?Vertical angles are two angles that are opposite by the same vertex when two lines cross each other, and they are congruent, that is, they have the same measure.
For this problem, the vertical angles are given as follows:
4x + 2.7x - 25.Since they are congruent, we can solve for the variable x as follows:
4x + 2 = 7x - 25.
Moving all the terms with x to the left side of the equality and all the constant terms to the right side, with opposite signal, we have that:
4x - 7x = -25 - 2
Combining the like terms, it is found that:
-3x = -27.
Here happened Maggie's mistake, as 4x - 7x = -3x, hence the correct solution is given by:
3x = 27
x = 27/3
x = 9.
