There were 816 people at a concert when a band started to play. after each song, only half the people stayed to hear the next song. how many people were left at the concert after x songs? write a function to represent this scenario.

What is the order of these fractions from least to greatest 2/3 7/10 5/8 65/100

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
