It says to solve each proportion which i forgot how to do. .

9 over 15 = x over 10

c over 14 = 6 over 21

0.2 over 1.5 = 2 over d

2x over 6 = 4x+8 over 15

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

If angle 2=3x +1 and angle 3=2x +4what is angle 2

The function v(r)=4/3pir^3 can be used to find the volume of air inside a basketball given its radius. what does v(r) represent
