Here you will divide 500 by 6 to get the girl students, and 500 by 5 to get boys.
Now, since I don't want to actually work hard in class, I fail purposely to stay in normal and not advanced. However this is just a algebraic problem with fractions. Add 2/3 to both sides, (I dont know what that gives you) you then have t = whatever. Hope this helpful! :D <span />
Notice that 50 minutes is twice the half-life.
After 25 minutes, half of the starting amount remains, so that 88g decays to 44g.
After another 25 minutes (a total of 50 minutes), the 44g will decay to 22g.
35:50 simplified is 7:10 because 5 goes into 35 7 times and 5 goes into 50 10 times.
Answer:
answers us a because that's the less sign and 1 is less than 2
