X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.
Hello,
very simple they intercept supplementary arcs. (making a sum of 360°/2 for inscribed angles )
Answer:
attempt it, if it's too hard, sleep
that's what I would do lol
Step-by-step explanation:
Answer: B
We all know that area= LxW
The width that is being shown is 8ft. The length is 20ft. Therefore, you multiply 8 x 20 which gives you 160ft squared. Hope this this helps :)
5/13t= -9
Then t =( -9*13) / 5
T=-23.4
