Heather charges half-dollar for each eighth of a pizza find the unit rate

I don't know if this is what you were asking but the cost of an entire pizza would be $4.00.

Step-by-step explanation:

An entire pizza would be 4 dollars because you would multiply .50 times 4. .50 would be a half dollar so if its a half dollar per slice, it would cost $4.00 for an entire eight slice pizza.

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
