A study showed that the ratio of the number of people who use social media to the number of people who
don't use social media is 2:3. Based on the ratio, how
many people in a town of 500 people don't use social
media.
Two classmates solved this problem and their work is
shown below. Which classmate solved the problem
correctly? Explain the error in the classmate who
solved it incorrectly.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
