So 10/2 simplified is 5/1 which is on point 5. -9/2 is already simplified so in decimal form it is -4.5 which is -4 1/2, so you go down from 0 and mark it right where the BLUE dot is and the GREEN dot is 5/1. Hope this helps! :)

Determine the dimensions of the screen of a 42-inch TV with a 4:3 aspect ratio.

Nitella [24]

For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.

Therefore, to find the value of x, we use the Pythagorean theorem.

We have then:

$(3x)^2+(4x)^2=42^2$

Rewriting we have:

$25x ^ 2 = 1764\\x = \sqrt {\frac {1764} {25}}\\x = \sqrt {70.59}\\x = 8.4$

Then the dimensions are given by:

$4x = (4 * 8.4) = 33.6\\3x = (3 * 8.4) = 25.2$

Answer:

the dimensions of the screen are: 33.6* 25.2
