you have two hourglass sand timers, one that runs for 3 minutes and another that runs for 5 minutes. How do you time 7 minutes using these two sand timers?

46

Explanation:

Before starting the 7 minutes, run the 5-minute glass and 3-minute glass simultaneously until the 3-minute one ends. Then there will remain 2 minutes on the 5-minute hourglass. Now, start the time and run the 5-minute glass until it ends, then flip it over and run it again for the full 5 minutes.

Thus, we have 5 minutes minus 3 minutes to equal a beginning 2 minutes, then added to this another 5 minutes for a total of 7 minutes.

I hope this helps ^^

boccaccio employs the voice of his narrator dioneo to represent his ideas on the tension between masculinity and femininity.  while dioneo excites the members of the brigata and recognizes women for their unique skills and independent ideas, he concludes the decameron with a story reminiscent of the society from which these young aristocrats escaped, revealing misogynistic overtones.  dioneo boccaccio is able to explore the gender disparity which is inherent in 14th century florentine society.
