Answer:
15 mL of the solution with 20% water will be needed.
Step-by-step explanation:
Use the inverse relationship
10 mL * (18-15)% = x mL * (20-18)%
x = 10 mL * (3/2) = 15 mL
If you ate a third of the box and there ARE 16 left then you started with 48 originally
F(x)=3x2-11
f(5)=6-11
5f=-5
5f/5=-5/5
f=-1
Answer:
25 Cards
Step-by-step explanation:
