The ratio of students wearing sandals to those wearing sneakers is 5 : 1. If there are 30 students in the class, and all of them are wearing either sandals or sneakers, how many of them are wearing sandals? Explain your reasoning. If you get stuck, consider using a tape diagram. *

1/5

step-by-step explanation:

the dice has 6 sides and there is only one 5 in a dice.

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
