Eric has made great progress in rehabilitating his knee with his physical therapist. The therapist measures the angle of Eric's fully bent knee as 45o. This angle is represented by ∠BCD in the diagram. Eric then extends his leg until it is completely straight, 180°. What is the full range of motion of Eric's knee, m∠ACD?

If Josh can read 18 pages in 40 minutes, how long will it take him to read 90 pages?
Answers
Answer:
18=40
90? 40×90=3600÷18=200 pages.
Answer:
It will take him 200 minutes to read 90 pages.
Step-by-step explanation:
Josh can read 18 pages in 40 minutes.
Ratio of pages to minutes = 18 : 40
Number of pages to read = 90
Minutes = x
Ratio of pages to minutes = 90 : x
The relationship is proportional
18 : 40 :: 90 : x
Product of extremes = Product of means
18x = 40*90
18x = 3600
Dividing both sides by 18
[tex]\frac{18x}{18}=\frac{3600}{18}[/tex]
x = 200
Therefore,
It will take him 200 minutes to read 90 pages.

Plan a controlled experiment to investigate how an object’s position is related to the amount of its potential energy by measuring how high the ball bounces. Choose at least four heights from which you will drop the ball. The drop heights may be increased or decreased based on the bounciness of ball. Describe your experiment.
Answers
Answer:
Step-by-step explanation:
The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. The radius of the ball doesn't really matter, if you are measuring the height of the ball from the bottom of the ball to the ground.
A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy. After the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise. This energy lost in the bounce is a more or less constant fraction of the energy of the ball before the bounce. As the ball goes back up, kinetic energy (now a bit less) gets traded back for gravitational potential energy, and it will rise back to a height that is the original height times (1-fraction of energy lost). We'll call this number f. For a superball, f may be around 90% (0.9) or perhaps even bigger. For a steel ball on a thick steel plate, f is >0.95. For a properly inflated basketball, f is about 0.75. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference.

Step-by-step explanation:
[tex]c = \sqrt{ax^{2} + bx^{2}} = \sqrt{12x^{2} + 16x^{2}} = 20[/tex]
Answer:
a 25 square units
Step-by-step explanation:
first find the length of the two sides of the triangle (sides of square 1 and 2)
the perimeter of a square is the length of the side × 4
so to find the length of the side, divide the perimeter by 4
perimeter of square 1: 12 units
divide it by 4: 3 units, so that's the length of side 1
perimeter of square 2: 16 units
divide it by 4: 4 units, so that's the length of side 2
now use a2 + b2 = c2
3 squared + 4 squared = c2
and solve
9 + 16 = c2
25 = c2
square root of 25 = square root of c2
5 = c
So now multiply 5 × 5 to find the area of the square
25

Question 1- Y= -6x - 4
Question 2- -6
Step-by-step explanation:
If this is the original question, 12x + 2y = -8, you first need to move x to the right like so ----- 12x + 2y = -8
-12x - 12x
Leaving you with 2y = -12x -8. Then dived both sides by the Y coefficient ---------- 2y = -12x -8
/ 2 /2 /2
For the final answer---- Y = -6x -4
For question 2- Just take M from the top and put it in there ------- -6
Hope this helps. Comment below if you have any other questions. I'd be happy to explain!
12x+2y=-8
-12x on both sides
2y = -12x -8
/2 on both sides
y = -6x -4
