Which is true?
a
0.0038 > 0.004
b
0.0749 = 0.075
c
0.4731 > 0.5001
d
0.7910 = 0.791

D is true

Step-by-step explanation:

Lets look at all options.

Option A is not true because 0.004 is greater than 0.0038 by 0.0002 and 0.004 is not less than 0.0038

Option B is not true because 0.075 is not equal to 0.00749 in fact it is 0.001 greater than 0.0749.

Option C is not true because 0.5001 is greater than 0.4731 by 0.001 and not less than 0.4731

Option D is true because 0.7910 is equal to 0.791 and the only difference is the significant figures. 0.7910 has four significant figures and 0.791 has three significant figures.

step-by-step explanation:

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
