i hope im right!! :D
Step-by-step explanation:
6:3 boys to girls.
say for the sake of it, there are 60 boys and 30 girls.that makes 90 children.if 1/2 of the boys wore hats, then 30 boys wore hatsif 1/3 of the girls wore hats, then 10 girls wore hatsif 30 boys and 10 girls wore hats, then 40 children wore hatsif 40 children wore hats, then 40/90 children wore hats40/90 can be simplified to 4/94/9 children wore hats
<span>The <u>correct answers</u> are:
B) many triangular shapes can be inscribed in a given circle; and
D) exactly one circle can be circumscribed about a given triangle.
Explanation<span>:
One of our geometric theorem states that for any 3 non-collinear points, exactly one circle can be drawn through it. This explains answer D; the non-collinear points would be the vertices of the triangle, and only one circle can be drawn through those points (circumscrbied about the triangle).
For B, we can have many triangles inscribed in a circle; the differences in the measures of the angles used will create the different triangles.</span></span>
