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;
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

Petroleum is a very important part of our day to day life now. We use it almost every day and it has helped emerge the world of vehicles.
<h3>Remains of sea organism</h3>
The remains of ancient marine organisms and sea organisms are used to extract crude oil or petroleum which serve as a fuel for vehicles. These organisms are ancient marine plants, algae and bacteria.
Therefore it can be concluded that the type of fossil fuel in which the remains of sea organisms are converted to is petroleum or crude oil.

Answer:
In January 1919, two months after the fighting in World War I ceased, a conference was convened at Versailles, the former country estate of the French monarchy outside Paris, to work out the terms of a peace treaty to officially end the conflict.
Though representatives of nearly 30 nations attended, the peace terms essentially were written by the leaders of the United Kingdom, France and the United States, who along with Italy, formed the “Big Four” that dominated the proceedings. The defeated countries—Germany and allies Austria-Hungary, Turkey and Bulgaria—weren’t invited to participate.
