European colonialism and colonization was the policy or practice of acquiring full or partial political control over other societies and territories, founding a colony, occupying it with settlers, and exploiting it economically.
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
Answer:
The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration in which plants release water from their leaves during photosynthesis.
Explanation:
This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.
