Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.
64 / 160 = 0.4
0.4 * 100 = 40% ( percent she has already driven)
100% - 40% = 60% left.
keeping in mind that 250 days is not even a year, since there are 365 days in a year, assuming so, then 250 days is really 250/365 years.
6^2 + 20.1^2 =? 22.9^2
36 + 404 does NOT equal 524.41
These do NOT form a right triangle.
10.5^2 + 20.8^2 =? 23.3^2
110.25 + 432.64 = 542.89
Therefore, it is a right triangle.
