[(100x60) + (Tx40)]/100=Average, where T is you average on the other 40% of your grade. Example: your grade average is 90 before the test. You get a 100 on the big test. [(100x60) + 90x40)]/100 = [6000 + 3600]/100 = 96
90 percent is around B and A on a test.
10% of 90 = 990% 0f 10 = 9(10% of 90) + (90% of 10) = 18
If all three tests are worth the same amount of the final grade,then your average is 83.3 percent.We hope it's not in Math.
64%
Depending on the class and school a 90% grade is usually an A. 90 to 100 are considered, most places, A's.
90
Nine-tenths ------------------------------------------------------------------------ "percent" means "out of 100" → 90% = 90/100 = (9×10)/(10×10) = 9/10
It will depend on the professor and school policy; but 90% is usually an A-.
Increase 90 by 10 percent, by multiplying 90 times 1.10 or it is 99.
90% of 10= 90% * 10= 0.9 * 10= 9
90% of 10 = 0.90 x 10 = 980% of 90% of 10 = 0.80 x 9 = 7.2
