First term (a) = -31
Common Difference (d) = -27 - (-31) = -27 + 31 = 4
nth term = a + (n - 1)d = -31 + (n - 1)4 = -31 + 4n - 4 = 4n - 35
Hence, the formula is 4n - 35.
I am pretty sure its 43.2
Answer:
the clock will represent 4.5 billion years as 2.67 hours
Step-by-step explanation:
Data provided in the question:
Total time of history of Earth = 4.5 billion years
Representation of total time of history of Earth on clock = 12 hours
Therefore,
4.5 billion years = 12 hours
or
⇒ 1 billion year =
or
⇒ 1 billion year = 2.67 hours
Hence,
the clock will represent 4.5 billion years as 2.67 hours
It’s B for sure I hope you have a good day
