Question

Which inequality best models the situation if variable h is the number of hours Valerie might study each night?



Valerie's goal is to study more than 1 1/4 hours each night.



Which shows the possible number of hours she might study to reach this goal?



A.

h < 1 1/4

and h may be up to 3 hours.


B.

h ≥ 1 1/4

and h may be up to 3 hours.


C.

h > 1 1/4

and h may be up to 30 hours.


D.

h > 1 1/4

and h may be up to 3 hours.

Answer 1

D. 

Number of hours is more  than  1  1/4 hours.  it is given.  Also  the number of hours in the night cannot be 30 hours.  Perhaps it can be 3 hours or 4 hours atmost.

  so  h >  1  1/4 hours.    and      h  <= 3 hours.
