True. Percents are in hundredths, so you must divide the percent by 100 to get the decimal or the true number, and can then be used for calculations.
The sign in front of 37 is squared and you do it by squaring the 37 first and seeing if that rule is true or false.
Answer:
Speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
Step-by-step explanation:
Average speed of down stream = 22 km/h
Average speed of up stream = 6 km/hr
Consider the speed of boat in still water be x km/hr and speed of current be y km/hr
As such speed of down stream would be x + y km/hr and speed of down stream would be x - y km/hr. i.e
x+y = 22
x-y = 6
by solving these two equation, we get
2x=28
x=14 km/hr
y=16-13
y=8 km/hr
Hence, the speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
