Is there a proportional relationship between the length and width of tvs? check the table for equivalent ratios to support your answer. show work. length width 16 9 20 11.25 24 13.50

Yes, there is  a proportional relationship, because the ratio length/width is the same for all cases

Step-by-step explanation:

If the ratio length/width is the same for all cases, then they are proportional between them.

16/9 ≈ 1.78

20/11.25 ≈ 1.78

24/13.50 ≈ 1.78

Another way is to prove that they are proportional is to multiply and divide 16/9 by a constant, as follows:

16/9 = 16/9 * 1.25/1.25 = (16*1.25) / (9*1.25) = 20/11.25

16/9 = 16/9 * 1.5/1.5 = (16*1.5) / (9*1.5) = 24/13.5

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

pls mark as brainliest

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
