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
100% of the rolls would be less than 13. The highest number on one die is 6, so even if you roll 2 dice the sum of both dice will always be lower than 13.
It's a 1:1 probablility.
Answer:
$420
Step-by-step explanation:
Calculate 3% of 3,500:
0.03*3500 = 105
105 per year for 4 years:
105*4 = 420
Answer.
Answer is 9
Step-by-step explanation:
Multiply height by with.
1,1x8,1
then do whatever that equals times 2,5 and you should get your answer.
