Answer:
Step-by-step explanation:
The computation of the thickness of tire rubber for every lost 1,000 driven is shown below:
Data provided in the question
Inches of tread = 
In case of replaced = 
Based on the above information
Now in 40,000 miles, the ratio is
And for every 1,000 miles driven, the thickness is
hence, the thickness of tire rubber is
Remember that
![\sqrt[n]{x^m}= x^{ \frac{n}{m} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%3D%20%20x%5E%7B%20%5Cfrac%7Bn%7D%7Bm%7D%20%7D%20)
so
∛16=16^(1/3)
we know that
16=2^3 so
(2^3)^(1/3)
remember another rule
(x^m)^n=x^(mn) so
(2^3)^(1/3)=2^(3/3)=2^1=2

Answer:
18.3 cm
Step-by-step explanation:
So tallest tree = 279.7 cm
So shortest tree = 261.4 cm
So difference = 279.7 - 261.4 = 18.3 cm
