There are 64 ounces total in a half gallon
Three-forty one over one thousand XD
Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.
<span>You would have to wait 318 years for 1/5 (20%) of the Radium to disappear. 1590 is the point where half of the Radium would decay, so if you take 20% of that, it would equate out to 318 years. Radium has a long half life!</span>
You would divide 3600 by 4 which would be 900. 900×3 would equal to 2700
