Answer:
1 liter of water
Step-by-step explanation:
If 80 % is acid that's means 4 liters of the 5 is acid. (0.8 * 5)
The remaining amount is 1
Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
e 95,970 l dont know any work just looked it up sorry
