(1/3 mile) / (1/4 hour)
= (1/3 ÷ 1/4) mile/hour
= (1/3 · 4/1) mile/hour
= 4/3 mile/hour
It is 320 because if you divide 1000 by 10, you would get 100 (which would be equal to 10% of 1000) So if you multiply 100x3=300. then, 2% of 100 is 20, so you add that to 300 then you 320
Area of the whole figure = 0.5m^2 ( half * base * heighT)
Area if the circle = pi r^2 = pi k^2
So area of shaded part = 0.5m^2 - k^2 pi
The slope of the line is 5/9.
