Answer: 1. 2rs is 2 . r . s = 2rs 2. 18rst is 2 . 3 . 3 r. s. t = 18rst
3. 25ab is 5 . 5 a . b = 25ab 4. 30abc is 2 . 3 . 5 a . b . c= 30abc 5. 45abr is 3 . 3 . 5 . a . b . r
Step-by-step explanation: 2. 18rst is 2 . 3 . 3 . r . s . t because 2 x 3 = 6 x 3 = 18rst.
3. 25ab is 5 . 5 a . b because 5 x 5 = 25ab
4. 30abc is 2 . 3 . 5 a . b because 2 x 3 = 6 x 5 = 30abc.
5. 45abr is 3 . 3 . 5 . a . b . r because 3 x 3 = 9 x 5 = 45abr.
Hope this works! :) If not, I am sorry :(. If it does, Your Welcome! :)

Answer:
13.18651685
13.9
Explain:
890-238=652
652/890=0.7325842697 (Find out the percentage)
We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.
0.7325842697x18=13.18651685
As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)
And of course we need to round it to nearest tenth. So the answer would be 13.9!
