Answer:
√y/y c.
Step-by-step explanation:
2y/√4y^3
= 2y / 2 y^3/2
= 1 / √y
= √y/y
Step-by-step explanation:
Since the triangles are right angled and are similar,
by Pythagoras theorem,

Answer:
36
Step-by-step explanation:
171/(4+0.75) =36
you want it to be in minutes, so calculate the 45 seconds over 60 seconds, which is 0.75. Add that to the 4 minutes, and divide the total number of copies over the time used, and you have speed/minute.
