I desperately hope it would be an F, but due to grade inflation that's probably a C by now.
You got 75% correct.Reason:5 is 1/4 of 20, therefore meaning that you got 3/4 correct. And of course 3/4 = .75, or 75%
subtract the biggest # from the lowest. If you the numbers 10, 18, 2, and 20, to find the range you would do this: 20-2=18. So the range would be 18.
Assuming the room is 20 ft by 18 ft (the question does not say so), the area would be 20*18 = 360 square feet
well, if you went to school you would know the answer, i am in grade 6 and i kjnow the answer: A=LxW A=20x20 A=400ft sqrd. if you don't know why i got 400ft sqrd, you simply multiply 20 by 20 and your area is 400 ft sqrd. have a nice day!
As a percentage 18 out of 20 is 90%
If you get 2 wrong out of 20 then its a 90 percent
90% or A-
A or 80 %
90%, A*, A, 1st
It would be 80. You missed 20% of the 20 questions: you missed 4 questions.
I desperately hope it would be an F, but due to grade inflation that's probably a C by now.
assuming that the questions are all worth the same amount of points on a 1 to 1 ratio you can view your score as a fraction reduced to 9/10 which is 90%
If you got 20 problems wrong on a 75 question test your grade would be 73% or a C. You can find that by subtracting the amount of questions you got wrong from the amount you got right, 55 in this case. Divide the amount of correct questions by the amount of questions on the test to get .733333. That is the grade.
(18 ÷ 20) × 100 = 90 Therefore: 90%
Lets say a D+ is approx. a 68. ((88.3*.8)+(68*.2))*100= 84.24%
15 out of 20 would be grade of 75 percent.
