Step-by-step explanation:
Answer:
Approximately 76.5 mg.
Step-by-step explanation:
Given,
The initial quantity of the Bismuth-210, P = 233 mg,
Also, the rate of decay per day, r = 13 %
Thus, the quantity of the Bismuth-210 after 8 days would be,






Answer:
Step-by-step explanation:
Equate the two opposite Angles
7x - 31 = 5x + 13 Subtract 5x from both sides
7x - 5x - 31 = 13 Combine
2x - 31 = 13 Add 31 to both sides
2x = 13 + 31 Combine the right
2x = 44 Divide by 2
x = 44/2
x = 22
