Answer:
w=105rpm
Step-by-step explanation:
The link between The lineal movement and and angular movement is V=w*r
w has units in rad/s, r is the radio of the rotating/moving element .
15 miles per hour= 15*63360 in/h= 950400 in/h= 15840 in/min
with the above relation we can use the link we were talking in the first paragraph.
15840 in/min=w*24in.
w=660 rad/min
w= 660 /(2 pi) rpm= 105rpm
The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
A. They are equal to each other.
Add up each number and you get 19.53 for both groups then when you divide by 9 ( the amount of individuals in each group) you get 2.17 for both groups so the mean is the same.
-- It's exactly 10% shorter than 1 inch, and 92.5% shorter than 1 foot.
-- It's also approximately 0.01343 smoot (rounded).
-- It's also approximately 2.286 centimeters, or 22.86 millimeters,
or 0.0000142 mile.
-- It's also approximately 0.000 000 000 000 000 002 418 light-year.
You see, "9/10 inch" is known and understood precisely wherever inches are
used in the world (everywhere throughout Liberia, Burma, and the USA) exactly
because "inch" is a unit that's exactly defined and agreed on in all those places.
But when you come along and say "I don't know what an inch is, describe it to me
in terms of something else", then you throw people for a loop.
If you can tell us what other unit you want to measure with ... like a flower,
a finger, an animal, or something else that we're also familiar with, then
we'll compare "9/10 inch" to that item for you. But that won't be exact,
because all of those things come in different sizes, and none of them has
a standard size that everybody agrees on.
