max2010maxim [7]

Farming is a common economic activity around two important rivers in South Asia, the INDUS and the GANGES

Explanation:

Ganges and Indus are two of the major rivers flowing in South Asia. They came into existence a long time ago. These rivers along with the Brahmaputra are known to be the backbone of South Asia in terms of culture and economy. The three rivers have contributed to the rise of the earliest civilizations in history.

Farming is the major economic activity in which these rivers have contributed and still contributing to the present as the soil present around them is very fertile and is ideal for various crops such as  Wheat, Rice,Cotton,Sugarcane and Maize. The fertility of the soil is replenished when the rivers are flooded making it ready for next cultivation.

More than 75 percent

Explanation:

Let us carefully analyze this problem:

The half life of the rubidium isotope = 50 billion years

   The half-life of a radioactive isotope is the time it takes for it to decay to half of its original amount.

  Every 50years, we know that a rubidium isotope would split into half.

Initially when the isotope was formed, we would only have the parent atoms there. There wont be any daughter;

  ratio of parent to daughter = 100 : 0

When the isotope decays to half; we would have equal number of parent and daughter:

  ratio of parent to daughter at half life = 50 : 50

The age of the earth is about 4.6billion years;

this is;

          \frac{4.6}{50} x 100 = 9.2% of the half-life of the rubidium isotope.

At this time, we should know that only 9.2 percent of the daughter would have been formed.

The remaining parent would be 100 - 9.2 = 90.8% would still be left undecayed.

The ratio of parent to daughter  = 90.8 : 9.2

This is more than 75% of the parent
