Answer:
- 42 students; (28 students); 70 students
- (60%); 40%; (100%)
Step-by-step explanation:
The percentages total 100%, so the missing percentage is
100% - 60% = 40%
The numbers on the number lines are proportional, so now you can write ...
?/100% = 28/40% . . . . . . ? total students
Multiplying by 100% gives ...
? = 28/0.4 = 70 . . . . . total students
Then the 60% portion of students can be found two ways:
60% × 70 = 42 students . . . . 60% of students
70 -28 = 42 students

<span>Answer:
Let x = degree measure of the angle
So, the complement of the angle has degree measure 90-x
4/11 = x/(90-x)
4(90-x) = 11x
360 - 4x = 11x
15x = 360
x = 24°
Supplement = 180 - x = 156°
x/(180-x) = 24/156 = 2/13</span>
