Answer :
Final answer:
The width of a 42" TV with an aspect ratio of 16:9 is approximately 74.67 inches.
Explanation:
The aspect ratio of a TV is the ratio of its width to its height. In this case, the aspect ratio is given as 16:9. To find the width of the TV, we can set up a proportion:
16/9 = x/42
Cross-multiplying, we get 16 * 42 = 9x
Dividing both sides by 9, we find x = 16 * 42 / 9 = 74.67 inches
Therefore, the width of the 42" TV is approximately 74.67 inches, so option E does not match any of the given answer choices.
