Tommy is making a picture graph to show his friends favorite kind of music. he plans to use one musical note to represent 2 people. how many notes will he use to represent that 4 people chose country music?

He will use 2 musical notes to represent that 4 people chose country music.

Step-by-step explanation:

Given : Tommy is making a picture graph to show his friends favorite kind of music.

He plans to use one musical note to represent 2 people.

i.e. Number of musical note to represent 1 people =

i.e. Number of musical note to represent 4 people =

i.e. Number of musical note to represent 4 people = 2

Hence, he will use 2 musical notes to represent that 4 people chose country music.

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 .
