Answer:Jarvis's class average is 75
Step-by-step explanation:
The total possible average score for the math course is 100
a) If the teacher rates homework at 10%, it means that the total possible score for homework
is 10/100 × 100 = 10
If his homework average is 93, then his score would be
(93×10)/100 = 9.3
b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes
is 30/100 × 100 = 30
If his quiz average is 82, then his score would be
(82×30)/100 = 24.6
c) If the teacher rates test at 40%, it means that the total possible score for quizzes
is 40/100 × 100 = 40
If his quiz average is 72, then his score would be
(72×40)/100 = 28.8
d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes
is 20/100 × 100 = 20
If his final exam is 60, then his score would be
(60×20)/100 = 12
Jarvis's class average would be
9.3 + 24.6 + 28.8 + 12 = 74.7
Approximately 75
A, B, and C are the correct answers
Answers:
120kmh = 72.168mph
50kmh = 31.07mph
Explanation:
This is very simple, just multiply 120kmh by 0.6214 to get 72.168mph. Again multiply 50kmh by 0.6214 to get 31.07mph
Wouldn't you multiply 320,000 times 12, (for 12 months) and then divide by 4000? Or you could divide 320,000 by 4000 and multiply that by 12?
