Answer:
26.3 rev/min
Step-by-step explanation:
The angular velocity (ω) is the linear velocity divided by the radius ( r= 80 feet)
ω = 220/80 = 2.75 rad/s
The angular velocity and the frequency are related by:
ω = 2π*f
2.75 = 6.28*f
f = 2.75/6.28
f = 0.438 rev/s * 60s/1min
f = 26.3 rev/min
Answer:
B) 41.7
Step-by-step explanation:
Let 
, 
, and 
. Use the Law of Cosines equation to find angle A=x which is directly across from side 
:
Therefore, the correct answer is option B, which means you were right!
6 * 10^5 = 600,000
600,000/15 = 40,000
The pop of the small town is approximately 40,000 people
Where is the shaded region?
Answer:
384 cubic inches (in^3)
Step-by-step explanation:
volume = length * width * height
So find the volume of the large rectangle of the prism, then find the volume of the small rectangle of the prism. Add the two volumes together and the sum is your final answer.
