1,000,000,000,000 = One Billion.
None.
To estimate the number of human generations in 4.5 billion years, we can use an average generation time of about 25 years. Dividing 4.5 billion years by 25 gives approximately 180 million generations. However, this is a rough estimate, as generation times can vary significantly across different cultures and historical periods.
It is now accepted in the UK that a billion is 1,000,000,000 (one thousand million), (it used to be 1,000,000,000,000 ie, one million million). We use the comma, though I believe the period is used in the USA? Therefore, where I've shown a comma, simply assume it is a period if you are in the USA!
500% of 9 Billion would be: 9 Billion (100% of 9 Billion) + 9 Billion (200% of 9 Billion) + 9 Billion (300% of 9 Billion) + 9 Billion (400% of 9 Billion) + 9 Billion (500% of 9 Billion) = 45 Billion.
Assuming you mean billion*billion*billion = It is 1*10^27.
None.

The geologic time scale covers the entire history of Earth, which spans approximately 4.6 billion years. It is divided into eons, eras, periods, epochs, and ages to categorize and study Earth's history.
An eon is equal to one billion years. Eons are divided into eras which can be specific or non specific periods of time.
The era that featured long periods with no life forms on Earth is the Hadean Eon, which lasted from about 4.6 billion to 4 billion years ago. During this time, the Earth was still forming, characterized by extreme volcanic activity and a molten surface, making it inhospitable for life. It wasn't until the subsequent Archean Eon, starting around 4 billion years ago, that conditions began to stabilize, allowing for the emergence of the first simple life forms.
To estimate the number of human generations in 4.5 billion years, we can use an average generation time of about 25 years. Dividing 4.5 billion years by 25 gives approximately 180 million generations.

An eon is the longest geologic time period, typically lasting billions of years. It is subdivided into eras, which are further divided into periods, epochs, and ages.
Yes, the geologic time scale begins about 4.6 billion years ago with the formation of the Earth. It is divided into different eras, periods, and epochs based on significant geological events and changes in Earth's history.
500% of 9 Billion would be: 9 Billion (100% of 9 Billion) + 9 Billion (200% of 9 Billion) + 9 Billion (300% of 9 Billion) + 9 Billion (400% of 9 Billion) + 9 Billion (500% of 9 Billion) = 45 Billion.
Assuming you mean billion*billion*billion = It is 1*10^27.
Yes, 7 billion is between 1 billion and 10 billion.
