Pqrs and efgh are polygons that can be mapped onto each other using similarity transformations. the transformation that maps polygon pqrs onto polygon efgh is a followed by dilation with a scale factor of .

rotation with a dialation of 0.5

Step-by-step explanation:

efgh is smaller than pqrs and its a rotation

its a straight line parallel to the time axis

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
