Answer:
51
Step-by-step explanation:
A = Surface area of the Earth = 
Total number of people on Earth = 7.594 billion as of 2018 = 
We need to find the number of people living in each square km of land area.
So, we need to divide the number of people by the land area of the Earth.



So, 51 people will inhabit each square km of land area.
The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.

You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)
(9) As this is just 1 triangle you then need to multiply it by 2
bh = sqrt of 3 over 3 * 9</span><span>

If you would like to solve the above problem, you can do this using the following steps:
1.2 miles * 7 days = 1.2 * 7 = 8.4 miles ... Multiply 1.2 by 7.
2.4 miles * 7 days = 2.4 * 7 = 16.8 miles ... Multiply 2.4 by 7.
8.4 miles + 16.8 miles = 25.2 miles ... Add the two products.
The correct result would be A.
