A student scores 80% on a 30 question test. Use a percent equation to write the ratio of the actual number of questions answered correctly to the actual total number of questions.

80% of 30

= 30 × 0.8

= 24

So the student answered 24 out of 30 questions correctly.

24

Step-by-step explanation:

80/100 × 30=24 answers he got right

24/30 questions are right

to check we can multiply 24/30 ×100 to get 80%

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
