Final answer:
Applying the scale factor of 1:2 doubles each dimension of the picture. Therefore, the original 4x6 inch picture, when enlarged, will be 8 inches by 12 inches.
Explanation:
If Heather wants to enlarge a 4x6 inch picture using a scale factor of 1:2, it means she wants to double the size of the picture. To find the new dimensions, we multiply each dimension by the scale factor.
- The width will be 4 inches * 2 = 8 inches.
- The height will be 6 inches * 2 = 12 inches.
So, after enlarging the picture with a scale factor of 1:2, the dimensions of the picture will be 8 inches by 12 inches.
