Q: 33 is 50% of what number? 50/100=33/x 100*33=3300 50x=3300 3300 divided by 50=66 x=66 A: 66
0.66 = 33/50
55%
50 out of 59 is 85%.
If 50 is passing: right now the contribution towards the total grade is (.70)*52, so the total grade = (.70)*52 + (.30)*E [for the final exam grade]. If the target is 50 for the total grade, then 50 = (.70)*52 + (.30)*E, and solve for E = (50 - (.70)*52)/(.30) = 45.3333, so a grade of 46 would put the final grade over 50. By the way, the maximum possible grade of a 100 on the final will result in 66.4 for the total grade.
