Answer:
$93
Step-by-step explanation:
<em>It izz wat it izzzz!!!</em>
Since we are given with the identity of the chemical as Carbon-14, we obtain the half-life of the chemical from a reliable source and get a value of 5730 years. The equation that we are going to use for this item is,
A(t)/A(0) = (0.50)^(n/5730)
where A(t) is the current amount, A(0) is the initial amount and n is the number of years. We know from the given that the ratio of A(t) and A(0) is equal to 0.63. Substituting this to the given,
0.63 = 0.50^(n/5730)
n = 3819.48
Thus, the sample is approximately 3819.5 years old.
Step-by-step explanation:
15,729 = 10 000 + 5 000 + 700 + 20 + 9
= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)
We can also write it like this :
(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)
