15 girls
Step-by-step explanation:
There are 15 girls and 21 boys
√11
4 = x^2 -7
Add 7 to both sides
11 = x^2
Square root both sides
√11 = x
4 mm
The radius is half the diameter, so in this case the radius of each button is 4 mm.
The greatest common factor would be 12.
24: 1, 2, 3, 4, 6, 8, <u><em>12</em></u>, 24
60: 1, 2, 3, 4, 5, 6, 10 , <u><em>12</em></u>, 15, 20, 30, 60
Hope it helps!
