The scale factor that was used to create the given square will be given by: (length of image)/(length of pre-image) Length of image=3 Length of pre-image=1 thus the scale factor will be: scale factor=3/1=3
The scale factor that is used to create the dilation is a scale factor of 3. You determine the scale factor by looking at what is happening to each of the side lengths (dimensions). The original has side lengths of 1, and the new one has side lengths of 3. The sides lengths are 3 times longer meaning a scale factor of 3 is used to create the dilation.
5 dozen= 60 doughnuts 3;43-3;27 = 16 So it took him 16 minutes for 48 doughnuts 16÷48=0,3 so one doughnut takes him 30 seconds 60×0,3=19,99=20 so it takes him about 20 minutes for 5 dozens of doughnuts So it'll be 4;03
