a) Write an expression using rational numbers to represent the length of the pelican's dive.
b) How long is the pelican's dive?
Hi everyone!! Sorry, that this is a late post, but at least i did it :D
So, here are my answers for Question 12.
a) It says here that the pelican dives verically from a height of 3.8m above the water. (3.8) Then it says here that it then catches a fish 2.3m underwater. (-2.3). So, I think the expression using rational numbers to represent the length of the pelican's dive is 3.8-(-2.3)
b) For this one. I just added 3.8m to 2.3 like this 3.8+2.3. Then i got this for the answer 6.1m.
So, then this is the whole rational expression. 3.8-(-2.3)=6.1m
Well, that's all. Please comment on my mistakes. Thank you ! :D
