A triangle is placed in a semicircle with a radius of 4 mm, as shown below. Find the area of the shaded region. Use the value 3.14 for pie and do not round your answer. Be sure to include the correct unit in your answer.
The area of the shaded portion of the diagram is 9.12 mm²
How to find area of a figure?The triangle is inside the semi circle.
The shaded region of the semi circle is outside the triangle.
Therefore,
area of the shaded region = area of the semi circle - area of triangle
Therefore,
area of the semi circle = 1 / 2 πr²
where
r = radiusHence,
r = 4 mm
area of the semi circle = 1 / 2 × 3.14 × 4²
area of the semi circle = 50.24 / 2
area of the semi circle = 25.12 mm²
area of the triangle = 1 / 2 bh
where
b = base h = heightHence,
b = 8mm
h = 4mm
area of the triangle = 1 / 2 × 8 × 4
area of the triangle = 32 / 2
area of the triangle = 16 mm²
Therefore,
area of the shaded region = 25.12 - 16
area of the shaded region = 9.12 mm²

10. Physical Science Ski resorts require large amounts of water in order to make snow. Snowman Ski Area in Colorado plans to pump at least 1120 gallons of water per minute for at least 12 hours a day from Snowman Creek between mid-October and Late December. Environmentalists are concerned about the effects on the ecosystem. Find the minimum amount of water pumped in 30 days. Let y be the total number of gallons pumped x days after pumping begins.
Minimum number of gallons pumped after 30 days = 24,192,000 gallons
Explanations:The minimum amount of water pumped in 1 minute = 1120 gallons
The minimum number of hours used for pumping per day = 12 hours
Number of minutes in 1 hour = 60 minutes
Number of minutes in 12 hours = 12 x 60 = 720 minutes
The minimum amount of water pumped per day = 1120 x 720
The minimum amount of water pumped per day = 806400 gallons
Let the number of days used for pumping be x
Let the total number of gallons pumped x days after pumping begins = y
Since 806400 gallons is pumped per day:
y = 806400x
Minimum number of gallons pumped after 30 days, that is, x = 30
y = 806400 (30)
y = 24,192,000 gallons
Minimum number of gallons pumped after 30 days = 24,192,000 gallons

I need to estimate but I don’t understand
Answer: 270
Step-by-step explanation: A tip for multiplying a number with any power of 10 is to just "add" a 0 to the end of the number depending on how many 0's there are in the power of 10.
For example, there is one 0 in 10. So I would just add a 0 to the end of 27 to get 270. If I were to multiply 27 by 100, there are two 0's in 100 so it would be 2700. 27 x 1000 would be 27000.

Step-by-step explanation:
1. A tool rental company charges $25 for the first hour of a tractor rental. Each additional hour costs $20 per hour. Which statement describes the relationship between total cost and hours?
A It is proportional; each ratio for related pairs is equivalent.
B It is proportional; each x-term is a multiple of the previous term.
C It is not proportional; each ratio y/x for related pairs is not equivalent.
D It is not proportional; each x-term is not a multiple of the previous term.
Answer:
C. It is not proportional. y/x ratios are not equivalent
Step-by-step explanation:
Given a rental charge of $25 for the first hour and $20 for each additional hour, you want to know if the charges are proportional to the time.
ProportionalityIn this situation, if the relationship were proportional, the charge per hour (constant of proportionality) would be the same for every hour. Here, the first hour costs more, so the hourly charge is not constant.
Here, we have, for x=hours, y=dollars, ...
(1, 25) ⇒ y/x = 25
(2, 45) ⇒ y/x = 22.5
(3, 65) ⇒ y/x ≈ 21.67
The y/x values are not constant (because the charge per hour is not constant). The relationship is not proportional.

Identity the triangle congruence postulate (SSS,SAS,ASA,AAS, or HL) that proves the triangles are congruent
In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
Which postulate establishes the congruence of triangles SSS AAS SAS ASA?
According to the Angle-Side-Angle Postulate (ASA), two triangles are congruent if two angles and the included side of one triangle are congruent with two angles and the included side of another triangle.
Congruence exists between one comparable pair of sides.
Detailed explanation:
If two triangles have three matching angles that are congruent,
The following postulates will be required to demonstrate the congruence of the triangles:
1) AAS ( Angle-Angle-Side ) ( Angle-Angle-Side )
2) ASA ( Angle - Side - Angle) ( Angle - Side - Angle)
Since we require at least one pair of congruent sides in both postulates.
Given that two triangles have three congruent corresponding angles, the extra information that will be utilized to prove their congruence is that "they have one pair of congruent corresponding angles."

________3. the rate of a car traveled 240 kilometers in t hours?
_________A. Find the rate of the car if t= 2.5 hour?
_________B. what is the rate of the car if the time is doubled?
1. A fraction whose denominator is 3 more than it's numerator x: x/(x+3)
A. If x =6, then the value of the fraction is 2/3.
B. If the denominator is 8, then the fraction is 5/8.
2. The length of a rectangular garden with an area of 32 square meters and has width w meters: 32/w.
A. The length of the garden if the width 4 meters = 8 meters
B. The width of the garden if the length is 16 meters = 2 meters
3. The rate of a car traveled 240 kilometers in t hours = 240/t km per hour
A. The rate of the car if t= 2.5 hour is 96 km/hour.
B. The rate of the car if the time is doubled is 120/t.
1. Let 'x' be the numerator. Then the denominator is 3 more than its numerator. So the denominator = x +3.
Hence the fraction whose denominator is 3 more than it's numerator x: x/(x+3).
A. If x = 6, then x+3 = 6+3 = 9.
So x/x+3 = 6/9 = 2/3
So the fraction is 2/3
B. Denominator = 8
⇒ x+3 = 8
⇒ x = 8-3 = 5
So the fraction is x/x+3 = 5/8.
2. Area of the rectangular garden = 32 square meters
⇒ length x width = 32
⇒ length x w = 32
⇒ length = 32/w
So the length of a rectangular garden with an area of 32 square meters and has width w meters is 32/w.
A. Width, w = 4 meters
Then, length = 32/w = 32/4 = 8 meters
B. Length = 16 meters
⇒ 32/w = 16
⇒ w = 32/16
⇒ width, w = 2 meters
3. Distance travelled by the car = 240 kilometers
Let 't' be the time taken in hours.
Then, Rate of the car = Distance / Time taken
⇒ Rate of the car in t hours = 240/t kilometers per hour
A. If t = 2.5 hour, then,
Rate of the car = 240/2.5 = 96 kilometers/ hour
B. If the time is doubled, then time = 2t
Rate of the car = 240/2t = 120/t

Calc Limits. Question Attatched.
The first mistake on the finding on the continuity of the function happened on Step 3, hence option B is correct.
What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is, if these three conditions are respected:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
To verify the continuity on this problem, the limit was first found at x = 4. Following the standard procedure, replacing each instance of x by 4, an undetermined value of 0/0 is reached. Thus the correct procedure was undertaken, factoring each polynomial in the numerator and in the denominator, then simplifying the common terms and calculating the limit.
However, to calculate the numeric value of the function at x = 4, the simplification cannot be applied, each instance of 4 needs to be replaced.
Replacing each instance of x by 4, the denominator will be of 0, meaning that the function is not defined at x = 4, hence the first mistake was in Step 3 and option B is correct.

How much should you invest at 2.4 simple interest in Oder to earn $50 interest in 9 months?
By using the method of interest, principle is 2777.7.
What is interest?An expense associated with borrowing money or other assets is interest. The principal is the amount borrowed, and the interest is calculated as a percentage of the principal for a specific period of time. The expense of borrowing money is interest. It equates to a fee or additional charge the borrower pays the lender for the loaned amount, and is sometimes stated as a percentage. When you make a payment on a loan with simple interest, the money first goes toward the interest for that month and the rest is applied to the principal. S.I. = P R T, where P = Principal, R = Rate of Interest in% per annum, and T = Time, typically calculated as the number of years, is the formula used to compute simple interest.
Given that,
S.I= PTR
Simple interest= 50
Time= 9/12= 0.75
Rate of interest= 2.4
Principle amount=?
S.I= PTR
50= P x 0.75 x 2.4
50= P x 1.8
P = 50X1.8
P= 2777.7

Which of the following systems linear inequalities does the graph represent? Select all that apply.
To answer this question, first of all, we need to find the equation for each of the lines on the graph. To do so, we have to identify two points for each line, and then use the two-point form equation (of the line) to find the equation of each line.
Then, we have:
Equation of the solid lineWe identify two points: (1, 1) and (2, 2).
Then we have:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]Then if we label both points above:
• (1, 1) ---> x1 = 1, y1 = 1
,• (2, 2) ---> x2 = 2, y2 = 2
Therefore:
[tex]\begin{gathered} y-1=\frac{2-1}{2-1}(x-1) \\ y-1=1(x-1)=(x-1) \\ y-1=x-1\Rightarrow y=x-1+1\Rightarrow y=x \end{gathered}[/tex]Therefore, the equation of the line for the solid line is y = x.
Equation of the dotted lineWe can proceed similarly as we did before. Then we have:
The two points are (2, 4) and (4, 8).
Then we can label them as follows:
• (2, 4) ---> x1 = 2, y1 = 4
,• (4, 8) ---> x2 = 4, y2 = 8
[tex]\begin{gathered} y-4_{}=\frac{8-4_{}}{4_{}-2_{}}(x-2) \\ y-4=\frac{4}{2}(x-2) \\ y-4=2(x-2)\Rightarrow y-4=2x-4 \\ y=2x-4+4 \\ y=2x \end{gathered}[/tex]Therefore, the equation for the dotted line is y = 2x.
We need to remember that when we have the symbols < or > the inequality is represented by a dotted line. Conversely, when it appears additionally an equal sign in the inequality symbol, ≥ or ≤ the line is represented as a solid line.
If we see the graph, we can say that the graph is represented by the following inequalities:
[tex]\begin{gathered} y>2x\Rightarrow Dotted\text{ line} \\ y\ge x\Rightarrow Solid\text{ line} \end{gathered}[/tex]Since if we represent them graphically, we have - using a graphing calculator:
We can observe that the shaded area is the same as the one represented in the graph given in the question.
We can prove that if we take a point in the solution region as follows:
1. For example, we can test the point (-2, 2). Then we have:
[tex]\begin{gathered} 2>2(-2)\Rightarrow2>-4\Rightarrow True \\ 2\ge-2\Rightarrow2>-2\Rightarrow True \end{gathered}[/tex]Now, using this we can check if the other system of inequalities is equivalent to this:
We can check the following inequalities:
[tex]\begin{gathered} -2x+y>0\Rightarrow y>2x \\ -x+y\ge0\Rightarrow y\ge x \end{gathered}[/tex]Which is equivalent to the previous one.
In summary, we have that the systems of linear inequalities are the following:
[tex]\begin{cases}-2x+y>0 \\ -x+y\ge0\end{cases}[/tex][Third option]
And
[tex]\begin{cases}y>2x \\ y\ge x\end{cases}[/tex][Fourth option]
[The second and the third options are not answers since both have the symbol, ≥, - and it means that we have two solid lines representing the inequality system.]
[In the first option we have that the first inequality represents a solid line, and this is not the case. The dotted line is represented by y > 2x.]

A family of six consisting of a mother, father, and four children line up (shoulder-to-shoulder) for a family portrait in a random order. Find the probability mass function of the random variable X, the number of children located between the father and mother in the photograph.
The probability mass function for this is given by the table that is attached below.
Probability is defined as the proper fraction which signifies the likelihood of an event to occur.
Total number of possible arrangements of 6 people are 6! = 720
Here X can take value 0, 1, 2, 3, or4.
For the probability function : When X= 0 , it means there is no child between mother and father. Taking mother and father as one , number of possible arrangements of 5 people are 5!.
And mother and father can arranged themselves is 2! ways. So for X=0, possible ways are 5! *2 = 240.
Therefore the require probability at X=0 is given by:
P(X=0) = 240 /720 = 0.3333
For the probability function : When X = 1 , then there is one child between mother and father. Number of ways of selecting one child is C(4,1) = 4.
Mother and father can be arrange themselves in 2 ways so possible number of arrangements are 4 * 2 * 4! = 192
Therefore the require probability at X=1 is given by:
P(X=1) = 192 /720 = 0.2667
For the probability function :When X=2 , then there are two children between mother and father. Number of ways of selecting two children is C(4,2) = 6.
Mother and father can arrange themselves in 2 ways, children between mother and father can arranged themselves in 2 ways so possible number of arrangements are 6 * 2 * 2* 3! = 144
Therefore the require probability at X=2 is given by:
P(X=2) = 144 /720 = 0.2
For the probability function : When X=3 , then there are three children between mother and father. Number of ways of selecting three children is C(4,3) = 4.
Mother and father can arrange themselves in 2 ways, children between mother and father can arranged themselves in 3! ways so possible number of arrangements are 4 * 2 * 3!* 2! = 96
Therefore the require probability at X=3 is given by:
P(X=3) = 96 /720 = 0.1333
For the probability function: When X=4 , then there are 4 children between mother and father. Number of ways of selecting 4 children is C(4,4) = 1.
Mother and father can arranged themselves in 2 ways, children between mother and father can arranged themselves in 4! ways so possible number of arrangements are 1 * 2 * 4! = 48
Therefore the require probability at X=0 is given by:
P(X=4) = 48 /720 = 0.0667
Hence the probability mass function can be represented by a table below.

In the given question we have to find the cost of equity using the capital asset pricing model if the risk free rate is 4.5%, the beta is 1.75 and the equity risk premium is 4.25%.
Firstly we learn about terms used in this question,
The return needed by either a business or an individual to justify an investment in equity is known as the cost of equity.
The relationship between systemic risk, or the general dangers of investing, and expected return for assets, particularly equities, is described by the Capital Asset Pricing Model.
Since we have to find the cost of equity using the capital asset pricing model. So the formula is
Cost of equity = Risk free rate + Beta * Equity Risk Premium
Risk free rate = 4.5%
Beta = 1.75
Equity Risk Premium = 4.25%
Now putting the value in the formula
Cost of equity [tex]=4.5\%+1.75\times4.25\%[/tex]
Simplifying
Cost of equity [tex]=4.5\%+7.4375\%[/tex]
Cost of equity [tex]=11.9375\%[/tex]
Hence, [tex]11.9375\%[/tex] is the cost of equity using the capital asset pricing model if the risk free rate is 4.5%, the beta is 1.75 and the equity risk premium is 4.25%.
