Answer:
A triangle has sides of lengths 9,7, and 12 is not a right triangle .
Jim's time is 5:50 and John's time is 6:40.
first is 86
we know because of the sum of the interior angles of a triangle being 180, and that 5 + 6 =180
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
