Answer:
7.8 × 10-5 meters
Step-by-step explanation:
the length of the a human hair= 8.4 x 10^-5
length of the vicuna hair:0.000006 = 0.6 x 10^-5
===========================================
difference between human hair and vicuna hair:
8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)
= 10^-5 (7.8)
= 7.8 x 10 ^-5 meters
Answer:


Step-by-step explanation:
1. The number 8,848 is an integer and the number 8,586 is also a integer.
2. Therefore, to solve this problem you must convert the integers shown above to fractions (Because a rational number is that one that can be written as a fraction), as you can see below:
Write each integer as a the numerator of the fraction a write 1 as the denominator. This will not change the value.
Then you obtain the following fractions:


3. Then, the elevation of Mount Everest's peak as a rational number is
meters. The elevation of Kanchenjunga's peak as a rational number is
meters.
