Answer:
Step-by-step explanation:
Are the sides consistent with the Pythagorean theorem?
37² + 54² ≟ 62²
1369 + 2916 = 4285 ≠ 62²
Not a right triangle.
If t is the amount of time she used it, then it lost t*(5/min) percentage points; then she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.
This means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.
This means that she used her phone for 10 minutes and charged it for 20 minutes.
Should be Q, because it is more than 121, but less than 144. 121 is 9 away from 130, and 144 is 14 away. So, the answer would be
B) Q
