Answer:
1545.66 rad/h
Step-by-step explanation:
We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.
We know that,
1 revolution = 2π rad
1 hour = 60 minute
So,
So, the required angular velocity is 1545.66 rad/h.
Answer:
A) 0.105
B) 0.30
C) 0.70
Step-by-step explanation:
The probability of spotting moose is 0.15.
The probability of spotting loons is 0.70.
A) The probability of spotting moose and loons on the same day is =
0.15 * 0.70 = 0.105
B) The probability of spotting moose on two consecutive days is:
2 * 0.15 = 0.30
C) The probability of not spotting moose for two days is:
1 - P(Moose on two consecutive days) = 1 - 0.30 = 0.70
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?
5x2=−30x−65
Subtract -30x-65 from both sides.
5x2−(−30x−65)=−30x−65−(−30x−65)
5x2+30x+65=0
Use quadratic formula with a=5, b=30, c=65.
x = −30±√−400 / 10
No solution.
60 explination, its pretty simple
