Answer:
The scale factor is 1/2
Step-by-step explanation:
The coordinates of Point G are (4,6) and the coordinates of Point G' are (2,3). To get from 4 to 2 and 6 to 3, you have to multiply by 1/2. Therefore, the scale factor is 1/2.
To get the answer you have to multiply the number of coins per roll which is 40 by the number of rolls which is 25. So the equation you get is 40*25. And the answer you get is 1000
The ratio of 2:3 will not work. this is because when you add up all the parts of the ratio it should make a factor of 24. 2+3=5 which will not divide evenly into 24 whereas all the others will
