<span>Decimal amount remaining is 0.00012 (= 0.012%). Let's calculate number
of half-lives.</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:
106.6 cm²
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
A = 1/2(16.4 cm)(13 cm) = 106.6 cm²
The area of the triangle is 106.6 square centimeters.
Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.

Answer:
4
Step-by-step explanation:
First let’s write out the info:
<u>X Y</u>
5 10
2 ?
Five is to ten as two is to what? Well let’s find out.
Five times TWO is ten, so logically, we multiply two times two.
<em>2x2=4</em>
The answer is 4
I hope this helps! :D
pls give thx and brainliest if I’m right ;)
