Answer:
The angular velocity is 8.38 radians per minute
Step-by-step explanation:
From the question,
It takes 45 seconds to complete a full revolution,
That is, 1rev/45secs
First, we will convert this to revolutions per minute (rev/min)
1rev/45secs =
= 4/3 rev/min
Now, we will convert this to radians per minute (rad/min)
1 revolutions = 2π rad
4/3 rev/min =
= 8.38 rad/min
Hence, the angular velocity is 8.38 radians per minute
Answer:
i think a but not sure
Step-by-step explanation:
i always second guess myself but a was first answer for me
45833.333 rounded to two decimals is no such thing never heard of tha before can you look it up? i tryed to look it up and it says no such thing well i think it might be 4.5833333 because it says rounded two decimals. So i just moved the decimal up twice i guess and i think thats what it is maybe i dont know but yea can you be more specific maybe plz because i dont understand??
Answer:
10%
Step-by-step explanation:
10/100 = 1/10 = .1 = 10%
Percy probably made his estimate by rounding 0.58 per pound to 0.50, and rounding 2.03 for the price to 2.00. The 2.00/(0.50/lb) = 4 lb.
Percy's estimate is not unreasonable, but it is somewhat high (by more than 10%).
The cost, 0.58/lb, is closer to 0.6, a number that would cause Percy to estimate his purchase at 20/6 = 3 1/3 pounds.
When estimating, it is often useful to make an estimate of the error. This last estimate will be a little low, by about 3% due to the estimated cost and 1.5% due to the estimated total amount paid, for a total of about 4.5% low.
