What is the hourly utilization rate of each resource if the bottleneck(s) work nonstop during a 10-hour day?

Bess [88]

Answer:

100%

Step-by-step explanation:

Utilization rate =

Hours worked / total working hours per day

Since the bottle works nonstop during a 10-hour day, it worked 10 hours

Utilization rate in percentage = (10/10)×100%

= 100%

A half-dollar is worth 50 cents. how many half-dollar coins equal one doller

igomit [66]

If one is 50 cents, then to get to one dollar we need 2 of those. also, one dollar equals 100 cents, and 50+50=100, so then the answer would be that you need to have 2 coins of the half-dollar to get to 1 dollar. i hope that this helps you, have a great day! =)
