Answer:
300
Step-by-step explanation:
Since nobody failed, the number who passed one or the other was 100%.
P(O + W) = P(O) +P(W) -P(O&W)
100% = 80% +70% -P(O&W)
P(O&W) = 50% = 150 students
If 150 students are 50% of the examinees, then 100% will be 300 students.

Answer:
C) 99 in²
Step-by-step explanation:
you can divide this shape by drawing a horizontal line to create a 4x12" rectangle and a trapezoid with a height of (10-4) in and bases of 12 and 5"
area of rectangle: 12 x 4 = 48
area of trapezoid: 1/2(6)(12+5) = 3(17) = 51
total area = 48 + 51
total area = 99 in²
