What should the following rate be divided by to convert it to a unit rate? 16 inches/12 hours answers: a) 6/6 b) 2/2 c) 12 d) 12/12

  12/12

Step-by-step explanation:

I would say simply perform the division already indicated.

  (16 in)/(12 h) = 16/12 in/h = 4/3 in/h

__

Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:

  (16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
