Answer:
x=1250 students
Step-by-step explanation:
x= total amount of students
boys=60% of x
so left is 40% of girls given number is 500
so x=total number of boys+girls
X = (60/100)*X+500
X - (60/100)*X = 500
(40/100)*X = 500
X = (500*100)/40
x=1,250 students
Answer:
5/25 or 1/5
Step-by-step explanation:
You could do this with two weighings assuming its a two pan balance - (1) place three balls on each side - if they balance out then its the remaining three that has abnormal ball (2) out of that group, place one ball on each side - if balances it out, the abnormal ball is the remaining one.
If the weighing in step (1) does not balance out, grab the group of three balls that is light or heavy and repeat step (2) described above.
The gradient of the line is 2.5, the y-intercept is 5.
The equation representing the line is y = 2.5x + 5
Based on the concept mentioned in my previous answers to your questions, this means the shaded region is represented by y ≤ 2.5x + 5
