<span>This is true. Numerical data is just data that is measurable. Height, width, diameter, circumference, time and many other types of data would be considered numeric and these measurables are all used in various mathematical formulas to solve problems, so they are used in mathematical calculations.</span>
Option D is a linear equation, so it represents a direct linear variation.
Hope this helps!
Notice the picture below
due to equal sides on each scalene triangle, the angle bisector cuts the horizontal in half
thus, use the pythagorean theorem to get the "b" or opposite side
also notice, that "b" is also the altitude or height "h"
what's the area? well, area of a triangle is 1/2 bh
get the area of each triangle and sum them up, that's the area of the kite
7 : 5 = 7x : 5x
7x + 5x = 12x
12x = 48 ⇒ x = 48:12 = 4
7x = 7 · 4 = 28
5x = 5 · 4 = 20
Answer: 28 : 20
