Answer:
37.38
Step-by-step explanation:
Remark
The ratio tells you how they are divided between night and day.
In other words night/ day = 19/32
That's not what you want.
What you want is night over total.
Total
Total = night + day = 19.1 + 32 = 51.1
Night Percent
Night% = Night * 100 / Total
Night% = 19.1 * 100 / 32
Night% = 37.38 %
5
AB=CD (Opposite sides of a parallelogram are equal)
11x-13=42
11x=42+13
11x=55
x=55/11
x=5
Answer: 24.34 is his balance.
x= -8 and so y=35.....solving equation
