Answer: 30
Step-by-step explanation: square 24 and 18 (576 & 324) then add them together (900), then the square root of 900 is 30, so 30.
3/5 + 7/10 / 7/12 - 3/10
13/10 / (35/60 - 18/60=)17/60
10/13 x 60/17 = 78/17 = 4 10/17
Let's convert everything to minutes and create a fraction.
A day has 24*60 = 1440 minutes
4 hours and 20 minutes is 4*60+20 = 260 minutes
The fraction 260/1440 simplifies to 13/72 part of a day.
