Two fifths of the children in the nursery were boys. what was the ratio of boys to girls in the nursery?

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

explanation:

mordancy.

the number 100 represents the number of trials in the experiment.
