So, how much acid is there in 6 gallons? well is 20% acid or (20/100), so the amount of acid in it just (20/100) * 6 or 1.2, the rest is say water.
now, if we want a 90% solution, and say we add "y" gallons, how much acid is in it? well (90/100) * y, or 0.9y.
now let's add "x" gallons of pure acid, now, pure acid is just pure acid, so is 100% acid, how much acid is there in it? (100/100) * x, or 1x or just x.
we know whatever "x" and "y" amounts are, they -> x + 6 = y
and we also know that x + 1.2 = 0.9y
Answer: 40 out of 52 or reduced to 10 out of 13
Step-by-step explanation:
The probability of a heart is 13/52
You then have 39 cards left of 3 different suits
There will be 3 2's, 3 3's, 3 4's, 3 5's, 3 6's, 3 7's, 3 8's, 3 9's and 3 10's. (27 total)
27 + 13 = 40
40/52 or 10/13
