Answer:
B
Step-by-step explanation:
You are correct
If 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:Mai is moving faster
Step-by-step explanation:
Speed is given as = Distance / Time
Mai's speed = 50 / 6= 8.333 m/s
Priya's speed = 22 /10 = 2.2 m/s
Since Mai is moving at 8.333 meter per second compared to Priya who s moving at 2.2 meter per second , We can say Mai is moving faster
I got you !
Step-by-step explanation:
45 bulbs planted in first year.
65 bulbs the next year.
increase = 20 bulbs
Number of increase of planted tulip bulb is N = 65 - 45 = 20
( 20/45) x 100% = 44.4 % to the nearest tenths
