Answer:
3 1/2 hours.
Step-by-step explanation:
If the Half Time show is one-seventh of the show and lasts for 30 minutes, we can multiply that by 7 to get the total amount of minutes.
30 x 7 = 210
To convert the number of minutes to hours, 210 can be divided by 60 to result in a total of 3.5, therefore, the Super Bowl lasts for 3 1/2 hours.
Answer: 48
-10x+6y=54 then + it to each other
-6x-6y=-6
-16x=48
Pi^2 = 9.86960440109
