That is exactly 8 half lives.
After 8 half - lives only (1 / 2^8) or (1 / 256) of the original 30 grams will remain.
(1 / 256) =
<span>
<span>
<span>
0.003906250
</span>
</span>
</span>
So, 30 * <span>
<span>
0.003906250 = </span></span>
<span>
<span>
<span>
0.1171875 grams will remain.

0.04 is 1/10 of 0.4
0.4 x 0.10 = 0.04
hope this helps
Answer:
Step-by-step explanation:
Area of rectangle = length * width
= (x + 4) (5x)
= x *5x + 4 *5x
= 5x² + 20x
Perimeter of rectangle = 2*(length + width)
= 2*(x + 4 + 5x)
= 2*(6x + 4)
= 2*6x + 2 *4
= 12x + 8
Answer:
mean absolute deviation
Step-by-step explanation:
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
6/25.2
Multiply both sides by 5 so 25.2 is a whole number:
30/126
and then simplify by dividing by 6:
5/21 which is equal to 0.2381.
Hope this helps :)
