You want the coordinates of the image of the triangle defined by A(3, 4), B(4, 2), and C(1, 2) after it has been translated by (-3, 9).
TranslationThe translation amounts are added to the corresponding coordinates:
(x, y) ⇒ (x -3, y +9)
A(3, 4) ⇒ A'(3 -3, 4 +9) = A'(0, 13)

Rhonda and Shalene live together in an apartment, so they combine their income each week to pay for
their rent and bills. Rhonda's paycheck is modeled by the function r(x) = 22x + 50, where x is the
number of hours worked. Shalene's paycheck is modeled by the function s(x) = 30x – 25, where x is the
number of hours worked.
Which function represents their household income if they work the same number of hours?
A. (s - r)(x) = -8x + 75
B. (r + 3)(x) = 52x + 25
C. (r + s)(x) = 52x + 75
D. (r - 5)(x) = 8x - 75
Answers
The function that represents their household income if they work the same number of hours is 52x + 25.
Therefore the answer is B. (r + s)(x) = 52x + 25
Rhonda's paycheck is modeled by the function r(x) = 22x + 50, where x is the number of hours worked.
Shalene's paycheck is modeled by the function s(x) = 30x – 25, where x is the number of hours worked.
The function that represents their household income if they work the same number of hours can be determined by adding their individual income
(r + s)(x) = 22x + 50 + 30x - 25
(r + s)(x) = 52x + 25

Step-by-step explanation:
The model has a length of 15 cm.
Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.
Since the length on the model is 15 cm which is 15 units, then the true length would be;
15 × 1/500 = 0.03 cm

y = 2x + 1During the 2010 baseball season, the number of wins for three teams was three consecutive integers. Of these three teams, the first team had the most wins. The last team had the least wins. The total number of wins by these three teams was 252. How many wins did each team have in the 2010 season?
Answers
Answer: 83,84 and 85
Step-by-step explanation:
Let the number of win for the teams be x, x+1 and x+2 respectively. From the question, we are told that the total number of wins by these three teams was 252 for the 2010 season. Therefore,
x+x+1+x+2 = 252
3x+3 = 252
3x = 252 - 3
3x = 249
x = 249/3
x = 83
This means that the team with least wins has 83 while the second team has 84 and the team with most wins has 85.

Answers
The required probability of randomly selected person to be a man or a heavy smoker is given by 0.5525.
Total number of people is equals to 1124
Total number of men is equals to 531
Total number of heavy smoker is equals to 90
Man and Heavy smoker are mutually exclusive events.
Let 'M' represents man
And 'H' represents heavy smoker
Probability of randomly selected person is a man or a heavy smoker
= P( M ∪ H )
= Probability of a man + Probability of a heavy smoker
= P( M ) + P (H)
= ( 531 / 1124 ) + ( 90 / 1124 )
= ( 621 / 1124 )
= 0.5525
Therefore, the probability of a person to be a man or a heavy smoker is equals to 0.5525.

find the volume of the solid where the cone and half sphere are hollow. use 3.14 for pi.
Answers
The volume of the solid is 3839 in³.
To find the volume of the solid where the cone and the half sphere are hollow, we use the formula below
Formula:
V = πr²H-(πr²h/3)-(2/3πr³)
Where:
V = Volume of the solid
H = Height of the solid
h = Height of the cone
r = Radius of the base of the solid = Radius of the half cone
From the question,
Given:
H = 29 in
h = 29/2 = 14.5 in
r = 8 in
π = 3.14
Substitute these values
V = (3.14×8²×29)-(3.14×8²×14.5/3)-(2×3.14×8³/3)
V = 5827.84-971.31-1071.79
V = 3838.74 in³
V = 3839 in³
Therefore, the volume of the solid is 3839 in³.

The figure below is rotated 180° clockwise. What are the coordinates of the image of point A after this transformation?
Answers
Answer:
(-2, -1)
Step-by-step explanation:
The easiest way to approach this problem is to think of each quadrant as being 90 degrees. As you can see, each quadrant has a 90 degree angle.
If we were to move 2 quadrants (or 180 degrees) clockwise, we would end up in the third quadrant (- , -)
Because we are moving clockwise on the graph, the shape would also turn clockwise. 180 degrees is the halfway point, so the shape will appear to be upside down.
If you're a visual learner, I'd recommend finding a website with an online graph (something like desmos or geogebra) that would allow you to actually graph the points and change their position with commands.

The BOD: of a municipal wastewater is determined to be 168 mg/L at 15°C. The BOD rate constant, k is known to be 0.18 day at 15°C. Compute the BOD5 of the sample at 20°C. What would be the remainin
Answers
To calculate the BOD5 of the sample at 20°C, we need additional information about the BOD rate constant at that temperature. Without that information, we cannot provide a direct calculation or answer.
Biological Oxygen Demand (BOD) is a measure of the amount of dissolved oxygen consumed by microorganisms while decomposing organic matter in water. The BOD rate constant (k) determines the rate at which BOD decreases over time. To calculate the BOD5 (BOD after 5 days), we need the BOD rate constant at 20°C.
Assuming we have the BOD rate constant at 20°C, we can use the following formula to calculate BOD5 at 20°C:
BOD5(20°C) = BOD(15°C) * (k20 / k15)^(t5 - t15)
Where:
BOD5(20°C) is the BOD5 at 20°C,
BOD(15°C) is the initial BOD at 15°C (168 mg/L),
k20 is the BOD rate constant at 20°C,
k15 is the BOD rate constant at 15°C (0.18 day),
t5 is the duration in days (5 days), and
t15 is the duration in days at 15°C (assumed as 5 days).
Without the value for k20, we cannot calculate the BOD5 at 20°C or determine the remaining BOD.
To determine the BOD5 of the sample at 20°C and the remaining BOD, we need the BOD rate constant at 20°C. Once we have that information, we can use the provided formula to calculate the BOD5 at 20°C.

Answers
n(A U B) = n(A) + n(B) - n(A n B)
From the question;
n(A n B) = 7 n(A U B) = 54 n(A) = 35
substituting the values into the formular above and then solve for n(B)
54 = 35 + n(B) - 7

subtract 28 from both-side of the equation
54 - 28 = 28 - 28 + n(B)

did the percentage of the aging population (55 years or older) in state prisons passed the percentage of people aged 18-24 for the first time in 2016. true or false
Answers
True. In 2016, the percentage of the ageing population (55 years or older) in state prisons surpassed the percentage of people aged 18-24 for the first time.
This trend reflects the overall growth of the ageing population within the United States and is a result of various factors such as longer life expectancy, harsher sentencing laws, and an increase in older individuals being convicted of crimes.
As the ageing population in state prisons continues to grow, it poses several challenges for the correctional system. These challenges include providing appropriate healthcare and accommodations for older inmates and addressing the specific needs of this population, such as mobility assistance and specialized medical care.
In conclusion, the shift in the age demographics of state prisons has significant implications for the management and administration of correctional facilities. It is crucial to address the unique needs of the ageing population within these institutions and adapt policies and practices accordingly to ensure the well-being and fair treatment of all inmates, regardless of their age.
