Answer:

There would be 168 girls and 252 boys

Step-by-step explanation:

40% or 0.40 x 420 = 168

420 - 168 = 252

Answer: 252 Boys, 168 Girls

Step-by-step explanation:

420 would be 100% of the school students.

If you wanna find the number of girls, you need to divide 420/100 in order to get 1% and then multiply it by 40.

So then you would get

420/100 x 40 = 168

Then in order to get the boys just subtract 168 from 420

420- 168= 252

1.This circle is centered at the origin and contains the points two units away. Write the equation for this circle.
denis-greek [22]

Answer:

1. The location of the center of the given circle = The origin (0, 0)

The given points on the circumference of the circle = (1, √3), and (0, -2)

The general form of the equation of a circle, is presented as follows

(x - h)² + (y - k)² = r²

Where;

(h, k) = The coordinates of the center of the circle

r = The radius of the circle

∴ (h, k) = (0, 0)

The radius of the given equation is the distance from the center (0, 0) to either the point (0, -2) or (1, √3)

The distance from the center (0, 0) to the point (0, -2), which are points on the same ordinate,  r = y₂ - y₁

∴ r =  0 - (-2) = 2

r = 2

The equation of the circle is therefore;

(x - 0)² + (y - 0)² = 2²

∴ x² + y² = 2²

2. When x = 1, and y = √3, we have;

(1 - 0)² + (√3 - 0)² = 1 + 3 = 4 = 2²

When x = 0, and y = -2, we have;

(0 - 0)² + ((-2) - 0)² = (-2)² = 4 = 2²

Therefore, the points shown on the circle (1, √3), and (0, -2) satisfy the equation of the circle, x² + y² = 2² and are solutions to the equation of the circle

Boo, I need help.
MAXImum [283]

Answer:

12 is the correct answer

Step-by-step explanation:

1) so whenever we're dividing with fractions we need to change the division sign to multiplication and turn the second fraction upside down (reciprocal)

so

6*2/1=12

Julio did change the division sign to multiplication but he forgot to take the reciprocal of the second fraction (he left the second fraction as is)

what Julio did: 6*1/2=3

Hope this helps!
