What will be the new position of the point (−8, 4) when rotated through 90° anti- clockwise about the origin?
i. (−4, −8)
ii. (−4, 8)
iii. (4, 8)
iv. (2, 4)

we have

(x,y). rotation through 90° anti-

clockwise about the origin(-y,x)

point (−8, 4) when rotated through 90° anti-

clockwise about the origin(-4,-8)

Option.i. (−4, −8)

The answer to your question is there are 440 students

Step-by-step explanation:

Data

110 girls = 25% of the total students

The Total number of students = ?

Use a rule of three to solve this problem

                    110 girls 25%

                      x            100%

                      x = (100 x 110) / 25

                      x = 440 students
