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? A 8 B 17 C 34 D 51

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer i believe is 27 units.
