For this case we have the number in exponential notation:

We observe that the exponent of the exponential notation is positive.
Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.
We have then:

Answer:
this distance written as a whole number is:
miles
18% I believe. Because you do the math then you rounded out and then I get 18%
Constant of proportionality is the constant value of the two proportional quantities, in this problem p and s, where 4 is the factor of proportionality because it is constant or k.
In simple terms, p is in direct proportion to s wherein the increase or decrease in value of s results to the increase or decrease in value of p with 4 the only factor remaining unchanged.
In the above problem, the number 4 is derived from the word square. We all know that a square has 4 sides of equal lengths, therefore, the perimeter is equivalent to the product of 4 and its lenght.
You add the numbers of all 4 sides.
