Ms. Day gave a test to her four math classes. There are 25 students in each class. There were 8 A’s in her first class, 9 A’s in her second, 10 A’s in her third, and 7 A’s in her fourth class. If there are 150 students in the grade, which of the following is the BEST prediction of how many students will earn an A on this math test?

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

c

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

irrational, cannot
