Of 200 people, how many people are in junior and senior high school?

college : 20%

high
school : 30%

junior and senior high school :

For this case, we have that the total of people is 200.

If there are 20% of those people in the college, then we make a rule of three to determine the amount:

200 -----------> 100%

x ----------------> 20%

Where "x" represents the number of people who belong to the college.

So, we have 40 people belong to the school.

On the other hand, we use a rule of three to find the number of high school people:

200 ------------> 100%

y ----------------> 30%

Where "y" represents the number of people belonging to the high school.

So, we have 60 people belong to high school.

College: 40

High School: 60

60+40=100

452,489 to the nearest thousand is 452,000

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 .
