After 3 days a sample of radon-222 has decayed to 58% of its original amount.
Rina8888 [55]
The half-life of the radioactive substance can be determined through teh equation ln 2 = k (t 1/2) where k is equal to ln (1/(1-0.58)) / 3. Hence t 1/2 is equal to 2.40 days. To decay to 10% of the original amount, ln (1/0.90) / ( ln2) / 2.40, time is equal to 0.37 days.

I need help ASAP , so what’s the answer
aivan3 [116]

The answer would be A.) 1

To find this answer you solve for x. Subtract 3/2 from both sides. This will give you 1/2x = 1/2^x. Then, divide by 1/2 on both sides to get x = 1.

To check this fill in x with 1. Then solve.

  • 1/2 * 1/1 + 3/2 = 2^1
  • 1/2 + 3/2 = 2
  • 4/2 = 2
  • 2 = 2

Thus making 1 the answer. Here's an image to show how I got this. I hope this helps!
