Answer 4

Answer 5

alright zhang you can help

Answer 6

so what is your questions?

Answer 7

Yes I do, The Ratio of the size of the television screen to the distance a person should sit from it is 1:6, how far should the person sit away from the television.

Answer 8

do you mean how far away should a person sit *from a 20* inch television!

Answer 9

Yes! sorry I forgot that !

Answer 10

cause i have those questions before...

Answer 11

I don't understand it...i've struggled through math alot.

Answer 12

Just screensize * 6 then.

Answer 13

How do I screensize ?

Answer 14

well the 1 to 6 ratio means that you should sit 6 times farther than the screen size

Answer 15

its not given in the problem

Answer 16

So, how do I calculate that, it doesn't make any sense too me...so the answer is a person should sit 6 times farther then the 20 inch television screen?

Answer 17

oh it does tell you the screen size :)
yes you got it...20*6 = 120 in

Answer 18

1/6 = 20/x so x = 120 (In the question they should have identified the 1.)

Optimal is 1:6 ( one foot to a 6 inch television i assume.)

1/6 = 17/x = x = 104.....Most TV rooms aren't 104 feet long.

Answer 19

So he should sit 120 inches away from the screen?

Answer 20

But then theres more problems I baisically don't understand math whatsoever, and i'm failing the class, so I need ALOT of help :/
