60 x 5 = 300 days
So five half-lifes = 300 days
Starting amount = 500mg
<span>Amount after 1st half-life = 250 mg</span>
<span>Amount after 2nd half-life = 125 mg</span>
<span>Amount after 3rd half-life = 62.5 mg</span>
<span>Amount after 4th half-life = 31.25 mg</span>
<span>Amount after 5th half-life = 15.625 mg</span>
<span>Hence after 300 days, the amount of iodine-125 will be 15.625 mg out of 500 mg.</span>
That is C and B. The missing lengths
Answer:
C
Step-by-step explanation:
Evaluate the power:
Reduce:
Then simplify:
3h^4b^4/6h^5b
