r(t)=(\cos{t},\sin{t},t)
\\r'(t)=(-\sin{t},\cos{t},1)
\\t= \frac{3\pi}{6} = \frac{\pi}{2}
\\ r'(t)=(-\sin{\frac{\pi}{2}},\cos{\frac{\pi}{2}},1)
\\ r'(t)=(-1,0,1)
\\
\\x=0+t(-1)=-t
\\y=1+t\times 0=1
\\z= \frac{\pi}{2} +t

Mr .Rowley has 16 homework papers and (2 exit tickets to return. Ms. Alvera has 64 homework papers and 60 exit
Kisachek [45]

The ratio of of number of homework papers to number of exit tickets of Mr Rowley and Ms. Alvera are not equivalent.

<h3>Ratio</h3>

A ratio is a number representing a comparison between two named things. It is also the relative magnitudes of two quantities usually expressed as a quotient.

Mr Rowley:

  • Homework papers = 16
  • Tickets to return = 2

Ratio of number of homework papers to number of exit tickets = 16 : 2

= 16 / 2

= 8 / 1

= 8 : 1

Ms Alvera:

  • Homework papers = 64
  • Tickets to return = 60

Ratio of number of homework papers to number of exit tickets = 64 : 60

= 64/60

= 16 / 15

= 16 : 15

Therefore, the ratio of of number of homework papers to number of exit tickets of Mr Rowley and Ms. Alvera are not equivalent.
