The answer is 
Step-by-step explanation:
We ll have to find more information first to solve this question.
1. One mole = 6.022 x 10^23
Assuming one gallon of paint covers the 400 sq ft of area.
Thus total area which can be covered by 1 mole of gallon is

2. Now we will find the surface area of earth

The radius of earth is 2.1 x 10^7 Feet
substituting values

3. Now we will find out the number of planets of earth size which can be covered by mole of gallon of paint
= Total area one mole of gallon can cover / area of earth

The value of T in the equation if v = 42 is 12
<h3>How to solve algebra</h3>
Given:
T= v /6 + 5
If v = 42, find T
- substitute 42 for v in the equation
T= v /6 + 5
T = 42/6 + 5
T = 7 + 5
T = 12
Therefore, the value of T in the equation if v = 42 is 12
