Question

Select the correct answer from each drop-down menu. A quarter is approximately 0.07 inches thick. A dollar bill is approximately 4.3 × 10-3 inches thick. A is thicker than a by m × 10n inches, where m = and n = . Undo

Answer 1

m = 6.57 and n = -2

Explanation:

To answer this question, one will have to covert the thickness of a dollar to standard notation and then compare the two values.

4.3 × 10-3 = 4.3/1000

= 0.0043

Now, compare

0.07 =compared to 0.0043

0.07- 0.0043

= 0.0657

0.0657 = 6.57 x 10^-2

A quarter is thicker than a dollar by 6.57 x 10^-2..... 1

m × 10n........ 2

Comparing 1 and 2

m = 6.57 and n = -2
