how do u do this?

Question

hey everyone how do u find out how old you will be in seconds, i will be 13 next year. the final answer has to be with units plus, it has to be in scientific notation, please help me out and show me the steps in finding the answer, thank you

Answer 1

13 years times 365 days times 24 hours times 60 minutes times 60 seconds. Plus add 3 days for the 3 leap years. So that gives you 3days times 24 hours times 60 minutes times 60 sec.

For 13 years I get 410.0544 times 10 ^6 power in scientific notation. I just put all of these numbers in my calculator and set it on scientific notation. The answer is in seconds.

Answer 2

Alright, Step number one is, how many seconds in a minute? 60, right? Then there are 60 mintues in an hour, so, to find the number of seconds in one hour, you multiply 60 by 60 to get 3600.

- There are 24 hours in one day, so multiply 3600 by 24 to get the number of seconds in a day, 86400.

-Then, multiply the number of seconds in a day by the number of days in a year, to get 31536000.

-Now, multiply that by 13, the number of years, to get 409968000.

-plus, you need to add three extra days, for leap years, so that is 410227200

To put in scientific notation, it's 4.1x10^8

Scintific notation is done by placing a decimel after the first whole number(in this case 4) and then multiplying it by 10 to the power of how many places are after the decimel (8)

There, now you know how many seconds you have been alive!
