This one is a little tricky because of the conversion but .51 cm converts to roughly .2 inches (actually its .200787 but we will round to .2 for ease of math). 4 in/.2in = 20
Therefore the tree is 20 years old.
Footnote 1cm is equal to .3937 inches so it would be .51cm * .3937in = .200787in
Your new line has to have the same slope as the green line for them to be parallel, so start off with y=-3/4x+b.
Plug in (2,4) into the new line so 2 for x and 4 for y
It should look like 4=-3/4(2)+b
-3/4x2 is -1.5
Then add 1.5 to both sides and you should get 5.5=b
Your new line is y=-3/4x+5.5 and (0,5.5) is a point on the line
I do this differently from many people, but the answer is 25 miles. If they walk 5 miles every day, and it’s a 40 day process, you multiply 8 by 5, which equals 40. After that you multiply 5 by 5 and you get 25. Sorry if that’s hard to understand, but the answer is 25.
Answer:
0.8
Step-by-step explanation:
The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...
factor = (year 1 population)/(year 0 population) = 320/400
factor = 0.8
