After watching Donald Duck in Mathmagic Land, please type out three things that you learned from the video. Did you like the video? Why or why not? Please answer all parts to the question
Answer:
Hope this helps
Step-by-step explanation:
Mathmagic Land had taught me more about math that I never knew before. I learned that everything can be involved with math. It all starts at the Pythagoreans which were the Greek. An example of how math is used today, is by playing billiards.
In billiards, you have to have a good technique of how your going to hit the ball, (good angles,) and you have to have a precise calculation of the angle your going to hit it at.I also learned when you cut shapes like a sphere, it just makes more and more shapes.
This is what I learned watching the Mathmagic Land Video.
Yes, Donald Duck in Mathmagic Land taught me alot of things I did not know before.

This graph shows a reciprocal parent function.
Which statement best describes the function
A. The function is always increasing
B. The function is increasing when x<0
C. The function is never increasing
D. The function is increasing when x>0
Answer:
C. The function is never increasingStep-by-step explanation:
According to the graph, the line goes down in both sections as the value of x increases. It means the function is always decreasing.
Correct answer choice is:
C. The function is never increasingThe best describes the function is,
''The function is never increasing.''
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
This graph shows a reciprocal parent function.
Since, We have;
According to the graph, the line goes down in both sections as the value of x increases.

M is the midpoint of PQ. MQ=5x+8 and PQ = 6x+56, find PM
Answer:
PM = 58
Step-by-step explanation:
The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).
This gives us the expression for PM: x+48
Now, since these are both the two parts of the midpoint, by definition, we know they're equal.
You equal both equations and get x=10
You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.

In the student government election, Maddie received 20% more votes than her opponent. A total of 1,485 votes were cast for both candidates. How many votes did Maddie receive?
Answer:
Maddie got 810 votes
Step-by-step explanation:
We'll call Maddie's votes x, and her opponent's votes y.
x + y = 1485
x = y + 0.20y (because she got the same number of votes as her opponent, PLUS another 20% of that number. Divide 20% by 100 to get the decimal equivalent) This can also be written as x = 1.2y
So our system is
x + y = 1485 and
x = 1.2y
Substitute the second equation's value for x into the first equation:
1.2y + y = 1485 then solve for y
2.2y = 1485
divide both sides by 2.2
y = 675
substitute that in and solve for x
x + y =1485
x + 675 = 1485
subtract 675 from both sides
x = 810
Please let me know if you have questions on this answer. Hope it helps.
what is x/y+z=w to make x the subject of the formula
We can make x the subject of the equation by moving all the other terms to the opposite side of the equal sign while x is on the next.
x/y+z=w [multiply both sides by y+z]
x = w (y + z)
