A point on the edge of the roller travels the circumference of the roller in 1 revolution, so that its linear velocity is
(10 rev/s) * (2*(14.25 cm)*pi cm/rev) = 285 pi cm/s
or about 895.4 cm/s.
Triangle ABC is similar to triangle JKL. They both have the same angle amounts.
<span>the unit rate corresponds to the proportional relationship
shown in the graph is equivalent to the slope of the line. Which can be solve
using the formula:</span>
m = (
y1 – y2 )/ ( x1 – x2 )
m = (
0 – 9 ) / ( 0 – 6)
<span>m =
3/2</span>
One way is to find common factors
example
8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each
so factor
we can combine 36m-48m into -12m
we have
-12m/6m
common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2
answer is -2
