On Monday Katie spent 2 1/6 hours studying. On Tuesday she spent another 4 7/9 hours studying. What is the combined length of time she spent studying?

6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

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
