Answer:
Step-by-step explanation:
I'm not sure I know what the paper ball situation is, but I can tell you that especially when working with a set formula in physics, math or chemistry (I'd include biology if I knew any biology) that it is a good idea to write down your givens.
The equation you are given is going to fall apart once you know what your givens are and what they do.
I just looked up the Paper Ball Situation. This is a wonderful piece of physics. It immediately opened up all sorts of treasures once they experimenters thought of using tin foil. Givens are a necessity in such an experiment.
Make into equation
Y = 1/3x - 2
-5 = 1/3(-1) - 2, false
-1 = 1/3(3) - 2, true
Answer: (3,-1) is also on the line
Answer: C. 113.1 cubic centimeters
Step-by-step explanation:
Volume of a sphere= 
(3.14)(r)^3
Since we know r then just plug in to get 4/3(3.14)(3)^3= 113.1
So the answer is C
42 is the answer
Explanation:
50% of 80 is half of 80 which is 40
Then you would add 40 with 5% of 40
What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2
Then you would add the price with tax
40+2 = 42
