Answer:
1. 95=8x+55 8x=40 x=5 Reason: Since m and n are parallel, and a line traverse through it, they are corresponding angles, meaning that their angle is the same.
2. 200-2x=130 200-130=2x 2x=70 x=35 Reason: The two angles are the same because the "130-degree" angle's corresponding angle is the vertical angle of the "200-2x" angle.
3. Yes, we can use the corresponding angle theorem to prove that m and n are parallel.
4. No, there's not enough information to determine because both given angles are on line m, we need an angle on line n as well.
5. No, the same explanation as 4^^^ Vertical angles do not necessarily prove that two lines are parallel.
6. Yes, we can use the corresponding angles theorem, and then use the vertical angles theorem.

The size of shoe a person needs varies linearly with the length of his or her foot. The smallest adult shoe size is Size 5, and fits a 9-inch long foot. An 11-inch long foot takes a Size 11 shoe.
1. Name TWO POINTS on the line that expresses shoe size in terms of foot length:
2. Find the slope of the line that expresses shoe size in terms of foot length.
3. Write the particular equation expressing shoe size in terms of foot length in slope-intercept form.
4. If your foot is a foot long what size shoe do you need?
5. Bob Lanier, who once played basketball for the Detroit Pistons, wears a Size 22 shoe. How long is his foot? Include units!!
6. If plotted the graph of the adult shoe size versus foot length, what would the leftmost point be, based on the information given in bold print above? (the story problem before number 1)
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
Answers
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 :)
When jamel went to the store, he spent $7 on 2. 5 pounds of hamburger meat. What are two different ways to express the rate in this situation?.
Answers
These are two ways to indicate how quickly this issue is evolving.
Given;
Jamel bought 2.5 pounds of hamburger meat at the shop for $7. What are the two possible methods to state the rate in this case?
Since he buys 2.5-pound hamburger meat on 7$;
The two ways to explain the rate of this situation is
(I) the amount of meat per $ is 2.5/7 = 5/14
(II) the cost of meat is 7/2.5 = 14/5 = 2.8 /pound
a) The maximum amount of hamburger meat that can be purchased by spending 1 dollar pounds of hamburger meat can be purchased by spending 1 dollar

If there is inverse variation and y = 3 when x = 24 , find x when y = 18 .
Answers
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.

I need to find tan (theta) for angle theta , the angle between the x-axis and the line that connects the origin to point (3,2)

tan(θ) = 2/3
Step-by-step explanation:
You want the tangent of the angle θ between the x-axis and the line connecting the origin to point (3, 2).
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 ...
tan(θ) = y/x
tan(θ) = 2/3

Additional comment
In general, the tangent of the angle a line makes with the x-axis is the slope of the line. Your line has slope 2/3, and that is the tangent of the angle it makes with the x-axis.

Answers
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.

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.

2.Under feudalism, landowners were granted plots of land (called fiefs) by nobles in exchange for their loyalty and military service. The landowner, or vassal, was required to provide the lord with soldiers when needed and give him a portion of the land's produce. In return, the lord provided the vassal with protection from invaders.
Manorialism (how did it work)
Manorialism was an economic system that developed in medieval Europe. It was based on the control of land and the produce of that land by a lord. The lord would grant land to peasants in exchange for their labor and a portion of the produce. This system allowed for the development of large estates and the growth of a class of landowners.
Justinian ( identify and achivements)
Justinian was the Byzantine emperor from 527 to 565. During his reign, Justinian sought to revive the empire's greatness and reconquer the lost western half of the historical Roman Empire.
One of Justinian's most famous achievements was the construction of the Hagia Sophia, which was completed in 537. The Hagia Sophia is a former Greek Orthodox cathedral that was turned into a mosque after the Ottoman conquest of Constantinople in 1453. It is now a museum in Istanbul, Turkey.
Another of Justinian's accomplishments was the compilation of the Justinian Code, a collection of laws that codified Roman law and is still used as a reference today. The Justinian Code was instrumental in the development of modern legal systems.
vassal
