A class of students has 18 boys and 21 girls. Match each statement to the ratio that can be used to represent it.

6

_

7

Step-by-step explanation:

the numbers that can go intl the denominator are 1, 3, 7 the biggest number is 7 and can go into 21 3 times so its divided by 3 . divide the numerator by 3 and you get 6 over 7

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

you have to put the graph on here with the question
