Hence, 
A suitable calculator* can do this easily.
61°38'45" = (61 +(38 +45/60)/60)° ≈ 61.65°
_____
I like the RealCalc app for Android, but many graphing calculators also will do this conversion. Of course, you can simply evaluate the expression as above.
The factors of 1078 are 1, 2, 7, 11, 14, 22, 49, 77, 98, 154, 539, and 1078.
Answer:
The answer is 9/11.
Step-by-step explanation:
To find the answer you'd first add up how many patients you have:
80+10+20 = 110.
Now find out that how many patients are taking a real drug, which is represented by 80+10 = 90.
So, the probability of a patient NOT getting a placebo is 90/110
Simplified would be 9/11
Thus the answer is 9/11....
Percent of increase formula: new-original/original
so, 60-50=10
10/50 = x/100
therefore x equals 20 so 20%
