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

The temperature at 6:00 P.M. was 3°C. At midnight, the temperature was -2°C.
aliina [53]

Answer:

-5 degrees

Step-by-step explanation:

In this scenario, since the final temperature was the temperature that existed at midnight then that value is subtracted from the initial temperature which was at 6:00 PM. Therefore we do the following calculation...

(-2) - 3 = x

-5 = x

Finally, we can see that there was a change in temperature of -5 degrees between 6:00 P.M. and Midnight. Meaning that the temperature during this time dropped a total of 5 degrees. Since, real numbers include negatives then the answer to this question is -5 degrees
