Bennett says that it will take more than 7
minutes to make 300
revolutions.
A gear makes 50 revolutions
each minute. It can be
represented by the equation
p=50+, where r is the total
revolutions and t is the
number of minutes.
Betty says that 50
represents the constant
of proportionality, k.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

it would open into a square depending on the type of envelope i’m not sure about the second part
