The liquid outer core of the earth is 2300 km thick. A scale model of the layers of the earth has a scale of 1 inch: 500km. How thick is the liquid outer core of the model?

I'm terrible at math any here is appreciated.

Which graph represents the function g(x) = |x + 4| + 2?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
