Answer:
Can I see the graph?
Step-by-step explanation:
You need the info of the graph to get the answer.

Here we go ~
The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

Now we have to calculate the descent in 3.5 minutes ~


So, the airplane descends 2172.41 feels in three and a half minutes ~
3+3 is the answer to this
A^2+b^2=c^2
7^2+11^2=?
49+121=170
x= Square root of 170
Hope this helps!! :)
I am not good in this kind of question so maybe 84?
suppose the full marks for each of them is 100 so for 5 of them it will be 500 cause if you if you multiply 100 full marks by 5 it will be 500
so the answer to this question is maybe 84?
cause if you add all of them with 84 the outcome will be 400 and if you divide the 400 by 5 it will be 80
