Which of the following is the fourth vertex needed to create a rectangle with vertices located at (−15, 3), (−15, −6), and (25, −6)?
(−6, 25)
(−25, −3)
(6, −25)
(25, 3)
Answers
The missing fourth vertex needed to create a rectangle is (25, 3) option D.
Define the term vertices?Vertices (singular: vertex) are the corners or points where two or more lines, edges, or curves intersect and form an angle.
Here, the width of one side of the rectangle;
⇒ +3 - (-6) = 9 unit (left side y-coordinates)
Similarly the length of the rectangle;
⇒ 25 - (-15) = 40 unit (up-side x-coordinates)
Since a rectangular shape has two sets of equal sides of equivalent width (y-coordinates) and length (x-coordinates), we realize that the missing fourth vertex should be 9 units and 40 units over the point (25, -6). and (-15, 3)
So, we add 9 to the y-coordinate of (25, -6) and add 40 to the x-coordinate of (-15, 3) to get the missing vertex:
⇒ (25, -6+9) = (25, 3)
⇒ (-15+40, 3) = (25, 3)
Therefore, the missing fourth vertex is (25, 3)

From the given dimensions, it seems like the figure is a trapezoid.Therefore, the surface area of the figure is 300 square feet.
What is surface area?Surface area is the measure of the total area that the surface of an object occupies. It is calculated by adding the area of all the faces or surfaces of the object.
What is trapezoid?A trapezoid is a four-sided geometric shape that has one pair of parallel sides. It is also called a trapezium. The parallel sides are called bases and the non-parallel sides are called legs.
According to the given information:
To calculate the surface area of the figure, we need to split it into smaller shapes and then calculate their individual areas. From the given dimensions, it seems like the figure is a trapezoid.
The formula for the surface area of a trapezoid is (1/2) × (a + b) × h, where a and b are the lengths of the two parallel sides and h is the height.
Using this formula, we can calculate the surface area of the trapezoid:
Surface Area = (1/2) × (15 + 9) × 15 + 2 × 15 × 4
= (1/2) × 24 × 15 + 2 × 15 × 4
= 180 + 120
= 300ft²
Therefore, the surface area of the figure is 300 square feet.

HELPP!!!Show all work to identify the asymptotes and state the end behavior of the function f of x is equal to 3x divided by the quantity of x minus 9 end quantity.
Answers
First, we need to identify any vertical asymptotes. These occur when the denominator of the fraction equals zero. In this case, the denominator is x - 9, so there is a vertical asymptote at x = 9.
Next, we need to analyze the end behavior of the function as x approaches infinity and negative infinity. We can do this by dividing the numerator and denominator of the fraction by the highest power of x in the denominator, which is x. This gives us:
f(x) = (3x / x) / ((x - 9) / x)
Simplifying, we get:
f(x) = 3 / (1 - 9/x)
As x approaches infinity, the term 9/x approaches zero, so we can ignore it. Therefore, as x approaches infinity, the function approaches:
f(x) = 3 / 1 = 3
As x approaches negative infinity, the term 9/x approaches zero, so we can ignore it. Therefore, as x approaches negative infinity, the function approaches:
f(x) = 3 / 1 = 3
Therefore, the end behavior of the function is that it approaches y = 3 as x approaches infinity and as x approaches negative infinity. We can confirm this by looking at the graph of the function, which should have a horizontal asymptote at y = 3 and a vertical asymptote at x = 9.

A triangle has sides with lengths of 18 millimeters, 25 millimeters, and 15 millimeters. Is it a right triangle?
Answers
Answer:
We can use the Pythagorean theorem to determine if the triangle is a right triangle. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
Let's label the sides of the triangle as a = 18 mm, b = 25 mm, and c = 15 mm. We want to see if a right angle exists between sides a and b, so we will check if c² = a² + b².
a² + b² = 18² + 25² = 324 + 625 = 949
c² = 15² = 225
Since c² is not equal to a² + b², the triangle is not a right triangle.
Therefore, the answer is no, the triangle is not a right triangle.

class?
A 21 students
B. 24 students
C. 28 students
D. 30 students
Answers
As a result, the total number of pupils i Ms. Morales' class is 10x = 10(3) = 30.
30 pupils is the right response.
What does it mean?In math, a mean is the average of a data collection, which is calculated by adding all of the numbers together and then dividing the total of the numbers by the number of numbers.
If the boy-to-girl ratio in Ms. Morales' class is 3:7, the class may be divided into 10 equal portions, with three males and seven girls.
If x equals the number of guys in the class, then the number of girls in the class is 7x.
The total number of pupils in the class is the sum of the male and female students:
Total number of pupils = 3 times + 7 times = 10 times
To get the value of x, we must first determine the total number of pupils in the class. Ms. Morales's school has class sizes ranging from 22 to 34 pupils each class. Because 10x is the total number of pupils in the class, we must find an x value that gives us a total number of students between 22 and 34.
Let's see whether x = 2 works. If x equals 2, the total number of pupils in the class is 10x = 20, which is insufficient.
Let's see whether x = 3 works. If x = 3, the total number of pupils in the class is 10x = 30, which is between 22 and 34.
As a result, the total number of pupils in Ms. Morales' class is 10x = 10(3) = 30.

What are proportions?
In mathematics, a proportion is a statement that two ratios are equal. It expresses the relationship between two or more quantities that are directly proportional to each other.
Let's first assume that the total number of students in Ms. Morales's class is x.
According to the problem statement, the ratio of boys to girls is 3:7. This means that out of every 3 + 7 = 10 students, 3 are boys and 7 are girls. Therefore, we can write:
Number of boys = (3/10)*x
Number of girls = (7/10)*x
The problem statement also tells us that the class sizes range from 22 to 34 students. This means that the total number of students x must be a multiple of both 3 and 7, and it must also be between 22 and 34 inclusive.
To find the possible values of x, we can list the multiples of 3 and 7 that are between 22 and 34:
Multiples of 3: 24, 27, 30, 33
Multiples of 7: 28
We can see that the only multiple of both 3 and 7 that is between 22 and 34 is 21*4 = 84. Therefore, the total number of students in Ms. Morales's class is 84.

Shelter A has a capacity of 400 beds and is 70% occupied. Shelter B is 50% occupied. The ratio of the occupancy of Shelter A to Shelter B is 14 : 25. How many beds are in Shelter B?
Answers
The total number of beds in Shelter B is 10.2. This is because the ratio of the occupancy of Shelter A to Shelter B is 14:25, meaning that if Shelter A is 70% occupied, then Shelter B must be 50% occupied.
What is occupancy?Occupancy is used to measure the efficiency of a business or facility by determining how often a space is used, how long people stay in the space, and whether or not the space is being used to its full potential.
To calculate the number of beds in Shelter B, we need to first calculate the total number of beds in Shelter A. Since Shelter A is 70% occupied, we can use the following equation to calculate the total number of beds in Shelter A:
Total beds in Shelter A = (Occupied beds in Shelter A ÷ 70%) x 100%
Total beds in Shelter A = (400 ÷ 70%) x 100%
Total beds in Shelter A = 571.43
Since the ratio of the occupancy of Shelter A to Shelter B is 14:25, we can use the following equation to calculate the total number of beds in Shelter B:
Total beds in Shelter B = (Total beds in Shelter A x 25%) ÷ 14
Total beds in Shelter B = (571.43 x 25%) ÷ 14
Total beds in Shelter B = 10.2
Therefore, the total number of beds in Shelter B is 10.2. This is because the ratio of the occupancy of Shelter A to Shelter B is 14:25, meaning that if Shelter A is 70% occupied, then Shelter B must be 50% occupied. As a result, the total number of beds in Shelter B is 10.2.

A car company charges customers an initial charge plus a daily charge to rent cars. The initial charge is $40 and the daily charge is $35. The rental company charged Frank $180. Create an equation that can be used to find the number of days, x, that Frank rented the car.
Answers
Answer:
Total Charge = Initial Charge + Daily Charge x Number of Days
Step-by-step explanation:
Let's assume that x is the number of days that Frank rented the car.
The initial charge for the rental is $40, which is a one-time charge, so it does not depend on the number of days.
The daily charge for x days is $35 per day. Therefore, the total charge for x days can be calculated as:
Total Charge = Initial Charge + Daily Charge x Number of Days
Total Charge = $40 + $35x
We know that Frank was charged $180, so we can set the total charge equal to $180 and solve for x:
$40 + $35x = $180
Subtracting $40 from both sides gives:
$35x = $140
Dividing both sides by $35 gives:
x = 4
Therefore, Frank rented the car for 4 days.

the endpoint of a diameter is simply a point on the circle arc.
the easy options are to assume that the center of the circle is on the x- or the y-axis.
let's go with the x-axis (we only need 2 circles : one with the center left, and one with the center right of the origin).
we know the radius is 3.
so, the center of either circle is 3 units away from the origin.
so, center of circle1 = (-3, 0), center of circle2 = (3, 0).
the equation for a circle is
(x - h)² + (y - k)² = r²
r is the radius, (h, k) is the center point.
equation for circle1 :
(x - -3)² + (y - 0)² = 3²

1. What is the annual depreciation expense associated with the new bottling machine?
2. What is the annual incremental net operating income provided by the new bottling machine?
3. What is the amount of the initial investment associated with this project that should be used for calculating the simple rate of return?
4. What is the simple rate of return on the new bottling machine? (Round your answer to 1 decimal place i.e. 0.123 should be considered as 12.3%.)
Answers
1. Depreciation expense = $7,400 per year
2. Incremental net operating income = $10,000 per year
3. The initial investment associated with this project is the cost of the new bottling machine, which is $74,000.
4. The simple rate of return on the new bottling machine is 13.5%.
What is investment?Investment refers to the act of allocating money or resources to acquire an asset or property, with the expectation of generating income, profit, or appreciation in value over time. It involves forgoing the use of funds in the present, in order to potentially receive a greater benefit in the future.
Annual Depreciation Expense:
The new bottling machine would have a useful life of 10 years, and no salvage value. Therefore, the annual depreciation expense associated with the new bottling machine is:
Depreciation expense = (Cost of the machine - Salvage value) / Useful life
Depreciation expense = ($74,000 - $0) / 10 = $7,400 per year
Annual Incremental Net Operating Income:
To calculate the annual incremental net operating income provided by the new bottling machine, we need to compare the annual operating costs of the old machine and the new machine.
Annual operating cost of the old machine = $19,000
Annual operating cost of the new machine = $9,000
Incremental net operating income = Annual operating cost of the old machine - Annual operating cost of the new machine
Incremental net operating income = $19,000 - $9,000 = $10,000 per year
Initial Investment:
The initial investment associated with this project is the cost of the new bottling machine, which is $74,000.
Simple Rate of Return:
The simple rate of return is the ratio of the annual incremental net operating income to the initial investment. We have already calculated the annual incremental net operating income in step 2, and the initial investment in step 3.
Simple rate of return = Annual incremental net operating income / Initial investment
Simple rate of return = $10,000 / $74,000 = 0.1351 or 13.5% (rounded to one decimal place)
Therefore, the simple rate of return on the new bottling machine is 13.5%.

What is a number line?
A number line is a visual representation of a line where the points are the real numbers. The line is usually drawn horizontally, with zero in the center and positive numbers to the right and negative numbers to the left. The numbers on the number line are evenly spaced and correspond to points on the line. A number line is a useful tool for understanding the relationships between numbers and for performing operations such as addition and subtraction. It is also used to represent measurements, such as distances and time intervals.
To find the midpoint of a line segment, we add the coordinates of the two endpoints and divide by 2. In this case, the coordinates of point S are -2 and the coordinates of point T are 7.
So the coordinate of the midpoint, point R, is:
R = (S + T)/2 = (-2 + 7)/2 = 5/2 = 2.5
Therefore, point R lies at 2.5 on the number line.

According to the equation given, someone who traveled 2000 miles from NYC would pay $800 for their airfare. (y = 200 + 0.30x, where x is the distance traveled in miles)
According to the equation given, someone who paid $500 for airfare from NYC would have traveled 1,000 miles. (500 = 200 + 0.30x, solving for x gives x = 1,000)
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y = 50 + 0.30x. (The slope remains the same, while the y-intercept changes to 50.)
Note that the statement "According to the equation given, someone who traveled 2000 miles from NYC would pay $2500 for their airfare" is incorrect. The correct calculation using the given equation y = 200 + 0.30x is:
y = 200 + 0.30(2000) = 800
Therefore, someone who traveled 2000 miles from NYC would pay $800 for their airfare.

Solve for x. 11=3+4x
Answers
To solve for x, we need to isolate the variable (x) on one side of the equation. We can do that by first subtracting 3 from both sides of the equation to get:
11 - 3 = 4x
Simplifying the left side gives:
8 = 4x
Finally, dividing both sides by 4 gives:
x = 2
Therefore, the solution to the equation 11=3+4x is x=2.
the solution to the equation [tex]11=3+4x[/tex] 11=3+4x is [tex]x = 2[/tex] X = 2.
The equation [tex]11=3+4x[/tex] 11=3+4x is a linear equation in one variable [tex](x)[/tex](x) with coefficients and constants that are real numbers.
It can be simplified by performing basic algebraic operations, such as isolating the variable term [tex](4x)[/tex] (4x) and solving for the value of [tex]x[/tex] x.
to solve for x in the equation [tex]11=3+4x[/tex] 11=3+4x, we will follow the steps of algebraic manipulation:
First, we will isolate the variable term [tex](4x)[/tex] (4x) by subtracting 3 from both sides of the equation:
[tex]11 - 3 = 4x[/tex] 11 - 3 = 4x
[tex]8 = 4x[/tex] 8 = 4x
Next, we will isolate x by dividing both sides by 4:
[tex]8/4 = x[/tex] 8/4 = x
[tex]2 = x[/tex] 2 = x
Therefore, the solution to the equation [tex]11=3+4x[/tex] 11=3+4x is [tex]x=2[/tex] x=2.

ATU COVID-19 team of Marshalls has 13 lecturers, 15 students, 10 administrative staff and 12 modicul personnel. An executive committee of 16 is to be formed to strategize for their mode of operations to help contain the vinus on campus. What is the probability of foming this committee, if there should be equal representation on it?
Answers
The probability of forming this committee with equal representation is approximately 0.570 or 57.0%.
The total number of individuals in the ATU COVID-19 team of Marshalls is 50 (13+15+10+12). To form an executive committee of 16 with equal representation, we need to choose 4 individuals from each group (4 lecturers, 4 students, 4 administrative staff, and 4 medical personnel).
Using the combination formula, we can calculate the number of ways to choose 4 individuals from each group:
C(13,4) × C(15,4) × C(10,4) × C(12,4) = 715 × 1,455 × 2,385 × 4,095 = 7,976,476,875
Therefore, there are 7,976,476,875 possible ways to form the executive committee with equal representation.
To calculate the probability of forming this committee, we need to divide the number of possible ways by the total number of ways to choose any 16 individuals from the ATU COVID-19 team of Marshalls:
C(50,16) = 13,983,816
The probability of forming the executive committee with equal representation is:
7,976,476,875 / 13,983,816 = 0.570

write each of these ratios in lowest terms using a colon 3.0 to 1.2
Answers
Answer:
To write the ratio 3.0 to 1.2 in lowest terms using a colon, we need to divide both numbers by their greatest common factor (GCF).
The GCF of 3.0 and 1.2 is 0.6, since:
3.0 = 5(0.6)
1.2 = 2(0.6)
Dividing both numbers by 0.6, we get:
3.0/0.6 = 5
1.2/0.6 = 2
Therefore, the ratio 3.0 to 1.2 in lowest terms using a colon is:
