Convert to same units, then can cancel out units: 1 ft = 12 in → 1 in : 4 ft = 1 in : 4 x 12 in = 1 in : 48 in = 1 : 48 So the scale factor is 48.
The scale "4 cm = 1 m" is a factor of 1:25 (1/25th scale). 1m/.04m = 25
It depends where the centre of enlargement (dilation) was; it can be any value.As all you have given us is the change in the coordinate of the A vertex, so all we can conclude is that the centre of enlargement is somewhere along the line y + 2x = 0.Examples:If the centre is at (3, -6) then the scale factor is -6If the centre is at (0.5, -1) then the scale factor is -1If the centre is at (0, 0) then the scale factor is -3/4If the centre is at (-3, 6) then the scale factor is 0If the centre is at (-4, 8) then the scale factor is 1/8If the centre is at (-10, 20) then the scale factor is 1/2If the centre is at (11, -22) then the scale factor is 2If the centre is at (1.4, -2.8) then the scale factor is 6(As the centre tends towards ±∞ the scale factor tends towards 1 [from below towards -∞, from above towards +∞].)
A diliation is a reduction if the scale factor is: less than 1.

Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3

.004 = 1 or 1 = .004
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
