That is a rational number.
Answer:
14,146 years
Step-by-step explanation:
The annual multiplier is (1 -0.0049%) = 0.999951. We want to find the number of times this needs to be multiplied to make the product 1/2.
0.5 = 0.999951^t
log(0.5) = t·log(0.999951)
log(0.5)/log(0.999951) = t ≈ 14,145.514
The half-life is about 14,146 years.
Answer:
x=6
Step-by-step explanation:
3(x+2) = 24
Divide each side by 3
3/3(x+2) = 24/3
x+2 = 8
Subtract 2 from each side
x+2-2 = 8-2
x=6
X=the man's age
500-2x=394
-500 -500
-2x=-106
-2x/2=-106/-2
x=53
FINAL ANSWER: 53 years old
Hope this helps! :)
