Answer:
C). 0.39 grams
Step-by-step explanation:
First find how many half-lifes are in 3 hours:
3 hours ÷ 20 minutes = 9 half-lifes
Find the total left:
0.5^9*200 ≈ 0.39
The length of the trail is 98.5 KM, all you need to do is divide the total distance by the number of times she went on it.
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!
