Will if you would really like to know ... my nephew who is in 9th grade asked me to help him with his algebra 2 homework that the teacher gives him online ... there are some that I am not sure about; thus, wanting to help my nephew understand this material to the fullest of his abilities i asked for some help ... you know what happens when you assume right sudharaka?
Dear bringash,
In that case (thinking my assumption is incorrect!!) I shall give you my ideas about the question. The answer 2.5 is correct.
; (using the rules of significant figures.)
Since it is given that the answer could be rounded to first decimal place 2.5 is also correct.
Hope this will help you.
P.S: If you felt angry about my previous post I am really sorry about it. But MHF does not encourage any of it's members to give exam help.
