All u have to do is multiple 10 times 8 I think so 80
Answer:
262.5 minutes or 4.375 hours
Step-by-step explanation:
7/8=0.875
60 minutes=1 hours
5 is the amount Karen played
7/8 of 60 minutes will be 52.5 minutes since 0.875*60=52.5
52.5*5=262.5 minutes
262.5/60=4.375 hours
The points A and B and the center O of the circle form a right angle and AO = radius.
So by Pythagoras
16^2 = 15^2 + AO^2
AO = sqrt (16^2 - 15^2)
AO ( radius) = sqrt31 = 5,57 feet answer (to nearest hundredth)
