Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.

The table represents some measurements that Johnny recorded in his math class. What values COULD x and y represent, respectively

Law Incorporation [45]

Based on the given data set:

x 1 2 3 4 5
y 1 8 27 64 125

the relationship between the two variables is notably:

y = x^3

this formula represents the volume of a cube:

V = s^3

Therefore, the answer is C) Side length and volume of a cube.
