Aparallelogram is transformed according to the rule (x, y) to (x, y) . which is another way to state the transformation

Option d

Step-by-step explanation:

Given is a parallelogram.  This is transformed in such a way that it gets back to the original posiiton

This is possible only if rotated about origin with a degree of 360 degrees

If rotated for 90 degrees one quadrant shift only will be there.

180 degrees rotation will shift by two quadrants.

270 degrees rotation will shift by three quadrants.

360 degrees rotation only will shift by four quadrants hence gets back to original posiiton

Hence option d is right

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
