A student received an 82% on an exam. If there were 50 questions on the exam, which ratio would show the number of questions answered correctly?​

imma say 41:50

41:50 is the ratio that would show the number of questions answered correctly to the total number of questions if the student received 82% in a 50-question exam.

Step-by-step explanation:

1. First, divide 82 by 100, since this is what you would have originally gotten with the ratio.

82 ÷ 100 = 0.82

2. Then multiply it by 50 (since this is how many questions were on the test)

0.82 × 50 = 41 < (the number of questions answered correctly)

3. Now that you have the two numbers you need, you can assemble the ratio.

41/50

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
