Answer:
The age of the pottery bowl to the nearest year is 15606 years.
Step-by-step explanation:
Let the initial amount of C-14 in the bowl i.e. and today (say after t years) the amount of C-14 in the bowl i.e. N = 21.
Therefore, from the given equation we can write
{Since, k is give to be 0.0001}
⇒
Now, taking ln on both sides we get
ln 0.21 = - 0.0001t (ln e) {Since, }
⇒ - 1.560647 = - 0.0001t {We have ln e = 1}
⇒ t = 15606.47 years ≈ 15606 years
Therefore, the age of the pottery bowl to the nearest year is 15606 years.(Answer)
so I think u you divide something and you times and then you multiply it
(In English), your question would state the following:
<span>Calculate the circumference and circumference of the circle entered in a square 8 cm long.
</span>
So when finding the answer this this question, we know that the circumference would be the complete area of a circle.
So, I believe we would want to find what is the radius and the diameter that would make this circumference 8
.
The radius would then be (1.274).

Now in your own language (Croatian).
<span>Dakle, kad pronađemo odgovor na ovo pitanje, znamo da bi opseg bio cjelokupno područje kruga.
Dakle, vjerujem da bismo željeli otkriti što je radijus i promjer koji bi ovaj opseg mogao učiniti 8cm.
Radijus bi onda bio (1.274).</span>
t = number of tickets
15t ≥ 1500
so....
step 1. 15t ≥ 1500 --> divide both sides by 15 --> 15t/15 ≥ 1500/15
step 2. t ≥ 100
So 100 at the least, ticket should be sold to reach atleast $1500.
I hope this helps. :)
