A new study suggests that waiting at least an hour after dinner before going to sleep reduces your risk of stroke by about two-thirds.
And for every 20 minutes more that you wait, stroke risk drops another 10%, says researcher Cristina-Maria Kastorini, MSc, a nutritionist at the University of Ioannina Medical School in Greece.
The study does not prove cause and effect -- only that there seems to be an association between waiting an hour or more between dinner and bedtime and reduced stroke risk.
Results of the 1,000-patient study were presented here at the European Society of Cardiology Congress 2011.
Can you attach the sentences so I can help you?
N=3p and d=p-2 we are also told that:
p+n+d=110 using n and d from above we get:
p+3p+p-2=110
5p-2=110
5p=112
p=112/5
Which is not an integer...are we sure there is no typo in the question...
There are 3 times as many nickels as pennies
There are pennies-2 dimes
And the total is $1.10
Just checking, because something is off...
