You would need to add 360L of the 20% ethanol solution.
Answer:
9pr = 2q^2
Step-by-step explanation:
28.
px^2 + qx + r = 0
If one root is A then the other root is 2A
We have A + 2A = -q/p and A*2A = r/p
So 3A = -q/p so A = -q/3p and A^2 = r/2p so A = √ (r / 2p)
Equating these 2 equations:-
-q/3p = √(r / 2p)
q^2 / 9p^2 = r / 2p
9p^2r = 2pq^2
9pr = 2q^2 (answer)

Take the point (10,5)
5 = constant / 10
constant = 5*10 = 50
also for the point (4 , 12.5) constant = 4*12.5 = 50
Answer is 50
One third of 75 would be 25 because you divide 75÷3=25
