F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2 radius), that is:
w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!
Answer:
ruler(×,y)=(20,20)
Step-by-step explanation:
sorry if its wrong
anyways are you using a mac?
Let's say Alice is 4 feet tall and Bob is 6 feet tall. The ratio of their heights is the required Alice:Bob = 2:3. That means Bob is 3/2 = 1.5 times taller than Alice.
