How many questions do you have to miss to get an 80 on a 60 question test?
According to my grade calculator with a 60 question test your break point would be 30 for a D- and a 57 for an A+, so an 80% would 47 correct questions and that means you would get a B and that is missing 10 questions.
What is the grade if you miss 1 out of 7?
86% is usually a B.
If a number consists of two digits which add up to nine and when the digits are reversed the original number is decreased by forty five then what was the original number?
72 1) a+b=9 2) ab-ba=45==> 10a+b-(10b-a)=45==>9a-9b=45==>a-b=5 per (1) and (2) a+b+a-b=9+5 ==> 2a=14==>a=7 per (2) a-b=5==> b=2 ab=72; ba=27
How do you solve x squared -4x equals 41?
x² - 4x = 41 → x² -4x - 41 = 0 Using the quadratic formula: x = (-b ± √(b² - 4ac))/(2a) → x = (4 ± √(4² - 4×1×-41)/(2×1) → x = (4 ± √(4(4+41)))/2 → x = (4 ± 2√45)/2 → x = 2 ± √45 → x = 2 + √45 (≈ 8.708) or x = 2 - √45 (≈ -4.708)
