First we convert it in seconds.
Number of seconds in 1 minute = 60 seconds
Therefore,
Number of seconds in 4.2 minutes = 4.2 x 60 = 252 seconds.
Next we convert it in hours.
60 minutes make up an hour. So we can write,
Number of hours in 60 minutes = 1 hour
Number of hours in 1 minute = 1/60 hour
Number of hours in 4.2 minutes = 1/60 x 4.2 = 0.07 hour
Therefore, the video is 252 seconds or 0.07 hour long.
The correct answer to your question is 8.
Answer: P = 2
Step-by-step explanation:
18 = 2(p+7)
18 = 2(2P+14)
-14 -14
4 = 2P
2=P
The answer is $14 because 65% of $40 is 26 and 40-26=14
