24 ounces of sulfuric acid ?

Answer:

32 days

Step-by-step explanation:

Assume that the jar is full initially, containing 24 oz.  After how many withdrawals of 3/4 oz will the jar be empty?

24 - (3/4)n = 0, or

24 = (3/4)n, or 96 = 3n.  Dividing both sides by 3, we get n = 32.

The jar will be empty after 32 days.

G → D

Stella [2.4K]

There would be at least 92 million people who will own a computer in 2015.

I don't know how to make a function out of a percentage, that is why I used excel to compute annual population.
