WHAT I CAN DO Read, analyze and solve.
1. Cesar invited 300 kids in the party. Only 15% of the kids did notshow up. How
many kids came to the party?
2. Rosa got 20% of an 80 item test incorrectly. How many items did she get
correctly?
3. There were 50 pupils in Grade Ill. If 28% of the pupils were absent, how many
pupils were present?
4. Out of 50 pupils, only 48 pupils joined the educational fieldtrip. What percent
joined the trip?
5. Among the 50 pupils in a Grade 6 class, 6% are left-handed. How many are left-
handed?​

1.

300 x 0.15 = 45

300 - 45 = 255

255 kids came to the party

//

2.

80 x 0.20 = 16

80 - 16 = 64

She got 64 items correctly

//

3.

50 x 0.28 = 14

50 - 14 = 36

36 pupils were present

//

4.

48 / 50 = 0.96

0.96 x 100 = 96.0%

96% joined the trip

//

5.

50 x 0.06 = 3

3 pupils are left handed

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
