Then, add the two.
12+20=32
Step-by-step explanation:
If there is inverse variation and y = 3 when x = 24 , find x when y = 18 .
The value of x in the inverse variation is x = 4
Inverse variationInverse variation is express mathematically by; y = k/x
where, y and x = variables
k = constant of variation
We solve for 'x' in the variation using standard form for inverse variation:
y = k/x
Given; y = 3, x = 24
We now use the given information to find k.
Step 1: Substitute the given in to equation y= k/x; to
3 =k/24
Cross multiply
k = 3 * 24
k = 72
Step 2; The inverse relation for is y = 72/x since we have gotten k=72
For y = 18, we get
18 = 72/x
Cross multiply
18x = 72
x = 72/18
X=4
Therefore, the value of x = 4.

The inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.
According to the question,
We have the following information:
Gabriel pays a flat cost of $52.50 per month and $5 per gigabyte. He wants to keep his bill under $75.
Now, the number of gigabytes used are represented by g.
So, we will have the following inequality:
52.50+5g<75
Now, we will solve this inequality.
Subtracting 52.50 from both the side:
5g<75-52.50
5g<22.5
Dividing by 5 on both the sides:
g<22.5/5
g<4.5
Hence, the inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.

New york city will pay two men $36 million for their wrongful conviction in the 1965 assassination of civil rights activist. ?.
New York City will indeed pay two men $36 million for their wrongful conviction in the 1965 assassination of a civil rights activist.
How is the chronology so that New York City pays for the incident of wrongful conviction of two people for the alleged murder of a civil rights leader?
After carrying out further investigations into the lawsuits against 2 people, in particular Muhammad A. Aziz and Khalil Islam who were accused of the murder of the leader of civil rights activist, Malcolm X, it was found that the two defendants were victims of wrongful conviction. It was previously stated that the police appeared to be withholding evidence to weaken the charges leading to acquittal. However, in the end, the court gave an acquittal because it was known that Muhammad Aziz and Khalil Islam had been proven innocent. As a form of accountability, New York City is willing to pay 26 million dollars to the victims and an additional 10 million dollars from New York state.
In conclusion, the amount of money paid by New York City is a form of responsibility that has been approved for the wrongful conviction of Muhammad Aziz and Khalil Islam.

(a) for each method, the researchers will record the change in targeted exercise intensity for each person in the investigation. they will compare the mean change in intensity between those who exercise with a training partner and those who do not. (i) describe the population of generalization if method i is used. explain your answer. (ii) describe the population of generalization if method ii is used. explain your answer.
Random sampling: It is a type of probability sampling in which the researcher randomly selects a subset of participates from the population.
Biased Sample: Sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower and higher sampling probability than other.
The population generalized in this case, is almost random, the only problem here is that people that want to participate will participate so is likely that the sample is not totally randomized and that there is huge number of people that regularly exercises.
b) This case is less random than the previous , here all the people in the sample regularly do exercise and these people can choose is they prefer to work with a partner or not. So the sample is biased.
In method 01 we can conclude that the result apply to the whole population , whole in method 02 we can't conclude that just because the sample is biased.
Method 01: - Recruit volunteers who are willing to participate. Randomly assign each participate to exercise with a training partner or exercise alone.
So there are people who wants to participate but people don't necessarily do exercise normally day to day life. People also can't choose to work out in a team or alone.
Method 02: Select a random sample of people from all the people who exercise at a community fitness center. ask each person in the sample whether they use a training partner, and use the response to create the two groups.
The members in the sample are people who exercises regularly and we ask them if they work alone or with a partner then, we create two groups. so this is more biased sample.
The population generalization, in this case, is almost random, the only problem here is that only people that want to participate will participate , so is likely that the sample is not totally randomized and that there is a larger number of people that regularly does exercise tan people that do not do exercise.This case is less than random than the previous here all the people in the sample regularly do exercise and these people can choose if they prefer to work with a partner or not.

9.4725
You rounded to the nearest hundredths place. The 7 in the hundredths place rounds down to 7, or stays the same, because the digit to the right in the thousandths place is 2.

7. If manufacturer decided to begin offering adult shoes in smaller sizes, how long would the foot of a person be who wore size 0? Include units!!
PLEASE HELP
Answer:
The slope is 1/3, calculate the rest from there
Step-by-step explanation:
We can picture this as a graph with the x value being the shoe size and the y being the length of a foot in inches. If we visualize it that way, we have two points on the graph: (5,9) and (11,11). From this, we can calculate the slope. The formula for slope is change in y value/change in x value, or rise/run. The slope in this case would be 2/6, simplified to 1/3. From this, we know that every time the X value increases by 1, the Y value increases by 3. Using this, you can find the two points on the line yourself. The equation formula for slope is y = mx + b. M is the slope, and Y is the y intercept (the value of Y when X = 0). Since the slope is 1/3, the equation is y = 1/3x+(y intercept). I am not going to fully solve this problem for you because I have a feeling you need this answer for a test of sorts (because of the level of urgency) but with this information you can probably solve this yourself! Good luck :)

The car B was 10 miles east of Car A.
A function is a formula, rule, or law that specifies how one variable (the independent variable) and another variable are related. The linear equation is of the form Ax+By+C=0.
Where A and B are the coefficient and C is the constant.
Speed of car A = 45 miles per hour and the direction of car A is East.
The distance of car B from Johnstown after 2 hours is 100 miles, east
The distance of car B from Johnstown is given on the graph.
So , the initial distance of car A from Johnstown will be,
= 100 - 2 × 45
=100 - 90
= 10 miles
As seen from the graph, the initial distance, east, of car B from Johnstown is 20 miles.
So, the difference between the cars will be 20-10= 10 miles that means car B was 10 miles east of Car A.
Therefore, the car B was 10 miles east of Car A.

Given that;
There are two figures is shown in figure.
Now,
In first figure;
By using definition of proportional as;
⇒ 4 / 2 = 6 / (x - 2)
Solve for x as;
⇒ 2 (x - 2) = 6
⇒ x - 2 = 3
⇒ x = 3 + 2
⇒ x = 5
Thus, The value of variable in first figure will be;
⇒ x = 5
In second figure;
By using definition of proportional as;
⇒ y / 6 = 12 / 9
Solve for y as;
⇒ y / 6 = 4 / 3
⇒ y = 4 x 6 / 3
⇒ y = 24 / 6
⇒ y = 4

TangentThe tangent ratio is given by ...
Tan = Opposite/Adjacent
In the attachment, you can see that the side opposite the angle of interest is the y-coordinate of the point. The side adjacent is the x-coordinate. That means ...

WE have been given that the angles are;
(3x +10)° and 2x
WE need to solve the value of x then we use the linear pair;
(3x +10)° + 2x = 180
Solving;
(3x +10)° + 2x = 180
5x + 10 = 180
5x = 180 - 10
5x = 170
x = 36
Angle ABD = (3x +10)° = 3(36) + 10
= 108 + 10
