$4 and for $12 , you can buy three sandwiches

Step-by-step explanation:

Part A

According to the scale used on the graph, one sandwich is equivalent to $4.

So, a sandwich cost $4

Part B

The points (3 and 12) on the graph indicates that for $12, you can buy three sandwiches

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

ratio is 2 : 9

the answer is three

13.5 : 3
