1) find the simple interest:
principal: $6000
interest rate: 5%
time: 6 months

150 dollars in 6 months

Step-by-step explanation:

5% of 6000 is 300 cut a year in half you get half of 300 which is 150

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
