Solve using the Percent proportion.

A bicycle cost $250 last year. The same bike cost $200 this year. What percent of last year’s cost is this years cost?

Please help! This question is worth 10 points!

20% is my answer!

Step-by-step explanation:I first took the cost last year minus this year ($250-$200= $50. I then used $50 as a percentage of $250 which is 20%, hence 20% goes into 100% five times just like $50 goes into $250 five times. Hope this is the answer you are looking for.

the answer will be the last one

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
