years or year's
10 years is called a decade hence it is only a decade not decade of years
No.
Yes that is correct.
100x365.25=36,525 days "100 years = 36,525 days because of the leap years." This is close, but not correct. Leap years do NOT occur on centennials (for example, 2000) except I think every fourth one. The absolutely correct answer to this question is 36,524.22, but for simplicity's sake you could say 36,524.
To determine which two statements about a decade are correct, I would need to see the specific statements you're referring to. Generally, a decade is defined as a period of ten years, and it is often used to group years for historical or cultural analysis. If you provide the statements, I can help identify the correct ones.

Not unless you add the word "the" between "for" and "last."
No. "I have known him for 5 years." Would be more correct.
No, that sentence is not correct. That sentence should be: If you have been in love for 6 years.
The correct phrasing would be "B years' experience," indicating that the experience spans multiple years.
4 years
The correct spelling is triennium (a period of three years).
'Since the last ten years...' is correct, but is only part of a sentence.
32 Years, If My Math Is Correct.

about 10 years if my calculations are correct then it is approximately 114,079,552 years.
Both are adequate
