c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
Biased because the survey was conducted in a limited field of people aka health club which does not include other people, perhaps an unhealthy club? Or the people who are not a part of the health club? Or people who do not care about their health?
Answer:
There's no answer bc the question is physical impossible and doesn't make any sense what's so ever
I think that it is 60+2 which is not any of the answers provided
Answer: y = 10x
This line goes through the two points (0,0) and (1,10)
(0,0) means x = 0 and y = 0 pair up. At time x = 0 seconds, aka the starting time, the height is y = 0 (the balloon is on the ground).
(1,10) means x = 1 and y = 10 pair up. At time x = 1 second, the balloon is y = 10 feet off the ground.
