what grade are you
the second is bigger, meaning it has been dialated
and it is also lower, so it has been translated down
also btw its 15 points it splits it in half but thx luv
She answered %75 percent of the whole test correct.
100*30% is 30, lol. Basically if its every over 100, its just that number Please mark brainliest if correct :D
We can call the amount of questions they answered as 4x, 6x and 3x respectively. Since Chandran answered 30 questions, we know that 6x = 30 so x = 5. The total number of questions Kadir and Ping Wei answered was 4x + 3x = 7x and since we know that x = 5, the answer is 7 * 5 = 35 questions.
30 is half 60
Basically, 5x is the points earned by correct questions (5 points per right answer) and -2x is the points lost by wrong answers (2 points taken away for every wrong answer). The total points the contestant earned is 80, which is why we set this equation equal to 80. Hence, 5x-2y=80.
They also tell us that the contestant answered a total of 30 questions, so x and y combined would be the total number of questions. Hence, x+y=30.
Given : The Number of Correct Answers = 30
Given : Total Number of Questions = 40
⇒ The Number of Wrong Answers = (40 - 30) = 10
The Ratio of the Number of Correct Answers to Number of Wrong Answers is :
The Ratio of the Number of Correct Answers to Total Number of Questions is :
If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :
he got 30 correct ya yea
idk cant helphahah
