Our meeting started at 9:45 a. m. and ended at 12:45 p. m. how long did the meeting take in minutes

180 minutes

Step-by-step explanation:

The problem above needs "conversion of units" from hour to minutes. Remember that: 1 hour = 60 minutes

So, if the meeting started at 9:45 a.m. and ended at 12:45 p.m., then the meeting's duration is 3 hours.

The next step is to convert 3 hours to minutes since the problem is asking for the answer in minutes.

So, 3 hours x = 180 minutes (this is the answer)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
