The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies
The copy machine makes 105 copies per minutes.

2. The total number of ski trails is 12. That's how many numbers there are in the box.
3. The difference in length between the longest ski trail and the shortest ski trail is the biggest number minus the smallest number in the box. 3 1/8 minus 1 3/8 is 1 and 3/4. So the answer is 1.75 or 1 3/4, whichever one works.
4. There are 3 trails that are 2 7/8 miles long. so You do 2 7/8 times three or 2 7/8 plus 2 7/8 plus 2 7/8. That equals 8 19/40 which is the answer. Ti add them together first turn them into mixed numbers. 2 7/8 is the same as 23/8. 8x3=24. 23x3=69. 69/24 is the same is 8 19/40 through further simplification.
5. 3 1/8 plus 1 3/8 is 4 1/2 or 4.5
6. The shortest ski trail is 1 3/8. 1 3/8 times 3 is 4.125. 4 is greater than 3 which means Sam is automatically right.
