Answer:
The mass of element after decay at the rate of 28.6% is 2.2 grams
Step-by-step explanation:
Given as :
The mass of element = 490 grams
The decay rate is 28.6 % per minute
The time period = 16 minutes
Let The mass of element after decay = m
Now,
The mass after T minutes = Initial mass of element ×
The mass after T minutes = 490 grams ×
Or, The mass after T minutes = 490 grams × 4.562 ×
Or, The mass after T minutes = 2.235 grams
Hence The mass of element after decay at the rate of 28.6% is 2.2 grams Answer
The total amount of space that she bought was 2 1/10 pages.
<h3><u>
Fractions</u></h3>
To determine what was the total amount of space that she bought, you must perform the following calculation:
- 1/5 = 0.2
- 1/20 = 0.05
- 1/4 = 0.25
- 0.2x2 + 0.05x9 + 0.25x5 = X
- 0.4 + 0.45 + 1.25 = X
- 2.10 = X
Therefore, the total amount of space that she bought was 2 1/10 pages.
