Answer: 8.24x10^5 years, or 8.24x10^3 centuries
Explanation: Sequential conversions to arrive at a total population rate of 2.31x10^10 atoms/sec for the entire population. Total seconds would be (6.02x10^23 atoms/2.31x10^10 atoms/sec) = 2.60x10^13 seconds. No breaks allowed, then (2.60x10^13 seconds)/(3.1536x10^7 sec/year)= 8.24x10^5 years.
Explanation:
the table is not given plz send the table
So, the answer to 27.) would be <em>2x.</em> Both 6x and 2x can be divided by 2x, but they can't go any higher without the end-answer becoming a fraction. As such, 2x is the greatest common factor.
For 28.), x and x^2 can't be like terms, since like terms have the same variable and exponent :)
Hope I could help!
