Eighty percent of 20 answers were correct. how many were correct?
16 of them.
If i got 10 questions wrong out of 60 what is my grade?
To calculate your grade, first find out how many questions you got right by subtracting the wrong answers from the total: 60 - 10 = 50 correct answers. Then, divide the number of correct answers by the total number of questions: 50/60 = 0.8333. To express this as a percentage, multiply by 100, which gives you a grade of approximately 83.33%.
How many wrong answers can you get out of 200 questions to get a 70 percent?
You can get 60 questions wrong, which leaves you with 140 answers correct, giving you 70%.
What gives you 44?
There are infinitely many answers but the simplest is probably 44+0 = 44.
What does infinitely many solutions mean in math?
It means that a problem has an infinite number of correct answers. This could mean that there are no incorrect answers at all or that infinitely many correct answers alternate with groups of incorrect answers. An example equation of the first type is 3x + 23 = 3x + 23, in which all possible values of x are correct from -infinity to +infinity. An example equation of the second type is sin(x) = 0, in which the infinite set of numbers {..., -pi, -pi/2, 0.0, pi/2, pi, ...) are correct but the numbers between members of that set are incorrect.
