Answer:
m = 6.57 and n = -2
Step-by-step 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

Answer:
Step-by-step explanation:
84% of 150=126 (foreign coins)

answer: D) 10 kilometers
0.65 x 10 = 6.5
0.65 is 10 times as much as 6.5
