amount remaining, where n is a number of half-lives.
<span>Decimal amount remaining is 0.00012 (= 0.012%). Let's calculate number
of half-lives.</span>
<span>
</span>
⇒ 
⇒ 
⇒ n ≈ 13
<span>
Now we know that number of half-lives is 13.</span>
Number of half-lives is quotient of total time elapsed and length of
half-life.<span>
<span>So, total time elapsed is a product of length of
half-life (5,730 years) and number of half-lives (13). Since 5,730 years × 13 =
74,490 years, then the person died 74,000 years ago (rounded to the nearest thousand).</span></span>

Answer : Option 'b' is correct.
Explanation :
Since we know that the length of apparent solar day= 24 hours approximately
And the length of normal days = 23 hours 56 minutes 4.1 seconds
So, the approximate length of an apparent solar day from June 21, 2010 to June 22, 2010 will be 24 hours 0 minutes 4.1 seconds .
As we increase the length of normal days by 4 minutes .
So, Option 'b' is correct.
Answer: x = 20
Step-by-step explanation:
Hey there! If you have any questions feel free to let me know in the comments below.
Step 1: <u>Subtract 36 from both sides.</u>
3x = 96 - 36
Step 2: <u>Simplify 96 - 36 to 60.</u>
3x = 60
Step 3: <u>Divide both sides by 3.</u>
x = 60/3
Step 4: <u>Simplify 60/3 to 20.</u>
x = 20
