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!
35% because 35% of 80 is 28
Answer:
Free press is essential since the government does not control the press.
Step-by-step explanation:
For example, the Untied States has free press so authors can spread information (whether for good or evil) while other countries like China control their press and access to press outside of their country, making it much harder for citizens to see the world from another perspective rather than what the government is willing to tell them.
Since the United States is a democracy, it is important to allow their citizens to have the right to speech and the press if people want to form opinions of their own.
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
