At TopHill elementary school, 84% of the students are driven to school every morning. The student population is 450. What is the number of students who are not driven to school?

72 students were not driven to school

Step-by-step explanation:

First find the amount if students that got driven to school

84 percent *450

= (84:100)*450

= (84*450):100

37800:100 = 378

So 378 are driven to school

Subtract that from the total amount to get the amount who didn't get driven to school

450 - 378 = 72

72 student were not driven to school

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
