A pass code contains 6 digits. The first 3 digits of the code are all even (2,4,6, or 8) and the last 3 are all odd (1,3,5,7, or 9). If digits can be used more than once, how many possible codes are there?

8000

Step-by-step explanation:

The first 3 digits each have 4 options.

The last 3 digits each have 5 options.

The number of possible codes is:

4 × 4 × 4 × 5 × 5 × 5

= 4³ × 5³

= 8000

it 2

step-by-step explanation:

8^1/3=2

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
