Answer:

Step-by-step explanation:
400^2 = 160,000
5 2/6 = 32/6 = 16/3
6 70/30 = 250/30 = 25/3
16/3 * 25/3 = 400/9
400/9 / 160,000 = 1/3600
The ratio of the pink to white marbles is 20%
A(0,-1)
B(3√3/3, 2)
Slope of AB = (y₂ - y₁)/(x₂-x₁)
Slope = (2-1)/(√3/3 , -0)
Slope = 1/√3/3 = 1/√3 = √3/3
OR SLOPE = tan(a°) = √3/3 and a° = 30°
