We rewrite the equation:
y = y0 * e ^ (- 0.0002 * t)
In this equation:
I = represents the initial amount of the isotope
We have then:
89% of the isotope left:
0.89 * y0 = y0 * e ^ (- 0.0002 * t)
We clear the time:
e ^ (- 0.0002 * t) = 0.89
Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
-0.0002 * t = Ln (0.89)
t = Ln (0.89) / (- 0.0002)
t = 582.6690813
round to the nearest year:
t = 583 years
Answer:
There will be 89% of the isotope left in about:
t = 583 years
Answer:
the answer is x because its small
Answer:
use what
Step-by-step explanation:
<em>Convert percentage to fraction by dividing by 100</em>
16 2/3 = 16 2/3 ÷ 100 = 1/6
16 2/3 % of 96 = 1/6 x 96 = 16
<span>Ans: 16 2/3 % of 96 lamps = 16</span>
If you would like to order the following numbers from least to greatest, you can do this using the following steps:
<span>11, 3.30, 175, - 10
</span>- 10 < 3.30 < 11 < 175
The correct result would be <span>- 10 < 3.30 < 11 < 175</span>.
