C. The adjusting journal entry to recognize the depletion expense is as follows:
Adjusting Journal Entry:Debit Depletion Expenses $15,345,000
Credit Accumulated Depletion $15,345,000
To recognize the depletion expense for the current year.What is an adjusting entry?Adjusting entries are the journal entries made at the end of the accounting period to recognize unrecorded expenses, revenue, and other gains or losses.
An example of an adjusting entry is the entry to recognize depreciation, amortization, or depletion expenses.
The value of the mineral rights = $49,500,000
The estimated mineral deposit = 55,000,000 tons
Depletion rate = $0.90 per ton ($49,500,000/55,000,000)
The current year's tons mined and sold = 17,050,000 tons
Amount of depletion expense for the current year = $15,345,000 (17,050,000 x $0.90)

A car that travels from Las Vegas to Los Angeles averages about 60 mi/h. The distance from Las Vegas to Los Angeles is 270 miles. Write a function to represent the distance d remaining on the trip t hours after departure.
The distance remaining is given by the equation d = 270 - 60t
How to solve an equation?Speed is the ratio of distance travelled to time taken. It is given by:
Speed = distance / time
Let d represent the distance from Las Vegas to Los Angeles and t represent the remaining time after departure.
A car travels from Las Vegas to Los Angeles at about 60 mi/h. The distance from Las Vegas to Los Angeles is 270 miles.
Hence distance remaining is:
d = 270 - 60t
The distance remaining is d = 270 - 60t

By Angle-Angle theorem similarity ΔABC is similar to ΔA'B'C'.
Given two triangles are ABC and A'B'C'.
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
1) Triangle ABC is reduced to triangle A'B'C'
∠ABC=∠A'B'C'=90°
∠BAC=∠B'A'C'
So, by AA similarity
ΔABC≈ΔA'B'C'
2) Triangle ABC is enlarged to triangle A'B'C'
∠ABC=∠A'B'C'
∠BAC=∠B'A'C'
So, by AA similarity
ΔABC≈ΔA'B'C'
Therefore, by Angle-Angle theorem similarity ΔABC is similar to ΔA'B'C'.

At a party, there are 30 men, 16 of whom are without dates, and 30 women, none of of whom are without dates. Find the probability of picking someone at random and getting a person who is a woman or without a date?
For this type of probability question, there are different ways to solve the same question but let's analyze the situation and calculate as simple as possible.
For our question, there are two parts, the first one first is the probability to pick someone who is a woman. Once there are 60 people of which 30 are women, it means this probability is 30/60. Let's keep this probability.
Now let's move on to the second part. The situation where we pick someone who is without a date. once there are 60 people and all 30 women have a date and 16 men also have a date it means 30 + 16 - 60 = 14 people does not have a date. So the probability to pick someone without a date is 14/60.
Now once we have analyzed the two parts of the question, and we have two probabilities all we need is to sum our probabilities, as follows:
But why do we sum and do not multiply? Because we use the proposition OR at "Find the probability of picking someone at random and getting a person who is a woman OR without a date" If the proposition was AND we would have multiplied both probabilities.

8. Use the point-slope formula to write an equationof a line in slope-intercept form using the points(1/2,5) and (5/2,9)
We have the next two points:
- (1/2,5)
- (5/2,9)
And we must use the point-slope formula to write an equation of a line in slope-intercept
First, we need to calculate the slope of the line using the point-slope formula
[tex]\begin{gathered} y_2-y_1=m(x_2-x_1) \\ m=\frac{y_2-y_1}{x_2-x_1} \end{gathered}[/tex]Where (x1, y1) and (x2, y2) are the two points
Now, replacing the points
[tex]m=\frac{9-5}{\frac{5}{2}-\frac{1}{2}}=\frac{4}{\frac{4}{2}}=\frac{4}{2}=2[/tex]Now, we must replace the slope and one of the two points in the point-slope formula:
[tex]y-y_1=m(x-x_1)[/tex]Replacing m = 2 and (1/2, 5)
[tex]y-5=2(x-\frac{1}{2})[/tex]Finally, we must simplify to obtain the slope-intercept form
[tex]\begin{gathered} y-5=2x-1 \\ y=2x-1+5 \\ y=2x+4 \end{gathered}[/tex]ANSWER:

If the measure of ∠ C A B = 4 x + 14 and ∠ D A E = 6 x − 18 then find the measure of ∠ C A B
CAB and DAE are suplementary
Measure of CAB is 84.4, by using supplementary angle theory.
What is supplementary angle?
In geometry, two angles are referred to as supplementary angles if their sum is 180 degrees. For instance, if A + B = 180°, then A and B are considered supplementary angles. Complementary angles always result in a straight angle when combined (180 degrees).
Angles that add up to a precise 90 degree angle are said to be complementary. For instance, 30 degrees and 60 degrees are complementary angles.
We have given, CAB= 4x+14 and DAB = 6x-18
Both are supplementary angle
Therefore, CAB + DAB = 180
4x+14+6x-18=180
10x-4=180
10x=176
x=17.6
hence, CAB = 4(17.6)+14 = 84.4

Given the equation:
y = 828000 - 2700x
Where y is the value of the building and x is the number of months of use.
Let's find when the value of the building will be $666,000.
To find when the value will be $666,000, substitute 666000 for y in the equation and solve for x.
y = 828000 - 2700x
666000 = 828000 - 2700x
Subtract 828000 from both sides:
666000 - 828000 = 828000 - 828000 - 2700x
-162000 = -2700x
Divide both sided by -2700:
[tex]\begin{gathered} \frac{-162000}{-2700}=\frac{-2700x}{-2700} \\ \\ 60=x \\ \\ x=60 \end{gathered}[/tex]The value of the building will be $666,000 after 60 months.
Now, let's convert from months to years.
Where:

The graph that represents the system of inequalities is the graph attached below.
How to Determine the Graph of a System of Inequalities?The graph that would represent the system of inequalities must be two lines that intersect each other and have the exact slope and y-intercept of each of the lines on the graph.
Determine the slope and y-intercept of each of the inequalities, and also determine their boundary lines based on which inequality sign they have.
The line that represents the inequality, y ≥ ½x + 1, will be a solid line that has a slope of ½, and a y-intercept of 1.
The second line that represents the inequality, y ≥ -x - 2, will be a dashed line that has a slope of 1, and a y-intercept of -2.
Therefore, the graph that represents the features stated above for both lines is shown in the diagram below.

Either Table A or Table B shows a proportional relationship.
Plot the points from the table that shows a proportional relationship.
( If you can, can you save the image as and edit it it will help me out a lot)
Answer: Table A has a proportional relationship
See the diagram below
==================================================
Explanation:
Table A has a proportional relationship because all the points are on the same straight line. That line in this case is y = 2x
Whatever x is, multiply it by 2 and you'll get the y value
Example: If x = 4, then y = 2*x = 2*4 = 8 which gives the point (4,8)

Given:
m∠C = 70°
m∠CDE = 130°
Question 1:
To find ∠CDB, let's use the exterior angle theorem.
The exterior angle theorem states that the sum of 2 opposite interior angles is equal to the exterior angle.
Thus,
m∠C + m∠B = 130
70 + m∠B = 130
Subtract 70 from both sides:
70 - 70 + m∠B = 130 -70
m∠B = 60°
Now, use the triangle angle sum theorem to find ∠CDB.
The triangle angle sum theorem states that the sum of interior angles in a triangle is 180°
∠CDB = 180 - 70 - 60 = 50°
∠CDB = 50°
Question 2:
∠CBA = ∠C + ∠CDB
∠CBA = 70 + 50 = 120°
∠CBA = 120°
ANSWER:
∠CDB = 50°
∠CBA = 120°
