Answer:
Explanation:
To convert the length of an operatic aria from minutes to seconds, we can use the fact that there are 60 seconds in a minute.
Given that the aria lasts for 5.75 minutes, we can multiply this value by 60 to find the length in seconds:
5.75 minutes * 60 seconds/minute = 345 seconds
Therefore, the length of the operatic aria is 345 seconds.
Since the question asks whether the length expressed in seconds is less than or greater than 5.75 seconds, we can see that the length of the aria, 345 seconds, is greater than 5.75 seconds.
In summary, the length of the operatic aria expressed in seconds is greater than 5.75 seconds.
