Velocity of the ring wraiths relative to the air:
The speed 
is what we want to find - this is the speed at which the wraiths are flying in the air.
(Note: 
denotes velocity, while 
denotes speed)
Velocity of air relative to the ground:
The ring wraiths want their trajectory to be due north, which means their velocity relative to the ground should be
To an observer on the ground, 
is the speed at which the wraiths would appear to be moving in the air.
The relative velocities satisify

Answer:
The new perimeter would be 36cm.
Step-by-step explanation:
The perimeter would change because you add 3 to two sides, because the perimeter originally was 5+5+10+10. Now, it's (5+3)+(5+3)+10+10. Which is 36.
Answer:
Step-by-step explanation:
Additive identity is 0.
step 3 used the additive identity property.
There are two other fine ways to write 11/5 .
Ten of those fifths make 2 wholes, so 11/5 can be written as<u> 2 and 1/5</u> .
Or you could do the division that the fraction shows.
Divide 11 by 5, and find the other way to write it . . . . . <u>2.2</u> .
