The local library has a children’s section with pictures books and chapter books. the ratio is 2: 3. if there is a total of 500 books in the children’s section how, many chapter books are in the section?

300

Step-by-step explanation:

Look at the ratio (2:3). You can see that the numbers of "ratio units" add up to 5, and that the total number of books is 100 times that value. Then each "ratio unit" stands for 100 books.

3 ratio units of chapter books mean there are 300 chapter books.

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
