When we have a 75% of the wound healed, we have the following area:
area of the wound=(100%-75%) (initial area) =25% (initial area)
In this case:
area of the wound=25%(80 cm²)=20 cm²
A(t)=80(10^-0.023t)
If A(t)=20
Then:
20=80(10^-0.023t)
10^-0.023t=20/80
10^-0.023t=0.25
log (10^-0.023t)=log 0.25
-0.023t log 10=log0.25 log 10=1
-0.023t=log0.25
t=log 0.25 /-0.023
t=26.176≈26
The wound be healed (75%) in 26 days
Answer:
There are two bases of the Indian social division into castes. The castes system has been consolidated and fed by religious practices. Ancient Hindu texts speak about four castes or profession: brahmins (priests), warriors, merchants and workers. Brahmins were at the top of society, the elite. The other source is simply social practice. There are still several groups that are seen as inferior , the "untouchables" just like the dalits; they perform the lowest and dirtiest jobs. Though castes don´t exist formally in Indian law, they exist in reality and social and racial divisions run still deep in India.
