In 2010, total number of students in a school was 3200 and in 2011 it is increased by the ratio 6:5. Find the total number of students in 2011 in the school.

3321

Step-by-step explanation:

6+5=11

11*6=66

11*5=55

66+55=121

3200+121=3321

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

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
