The table shows whether pupils in a class have school dinners

Boys who have school dinners 6 boys who don't 4

Girls who have school dinners 7 girls who don't 3

What percentage of boys have school dinners=

What percentage of pupils in this class have school dinners

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Step-by-step explanation:

1. There are: 6+4 = 10 boys in the class ->  corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

2. There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%

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
