When x=1/4 x²=1/16 so f(1/4)=y=2 1/16 last answer
Set up and solve an equation of ratios. Comparing shadow lengths, we get 100/6; comparing heights, we get x/8. Set these two ratios equal to one another and solve the resulting equation for x:
100 x
----- = ------ Then 6x=800, and x = 800 feet^2 over 6 feet. Your answer
6 8
must have the unit of measurement "ft."
150 miles at a rate of 60 miles per hour. 150/60=2.5 hours
He figures that it will take 25 hours. Wrong
