The ratio of boys to girls in the freshman class is 2 : 3. If there are 120 boys in the class, how many are girls? * 40
120
80
180

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

if you was gonna solve for a, a is a   < -12

answer: entity is prob the answer

step-by-step explanation:

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)
