Answer:
A rainbow is caused by sunlight and atmospheric conditions.
Given:
WXYZ = 8m
W'X'Y'Z' = 6m
Pls. see attachment if it is similar to the figure that should have accompanied this problem. I simply edited the details to fit this problem.
WXYZ * scale factor = W'X'Y'Z'
scale factor = W'X'Y'Z' ÷ WXYZ
scale factor = 6m ÷ 8m
simplify: 6/8 → (6÷2) / (8÷2) = 3/4
The scale factor is 3/4

Answer:
The statement is not true.
Explanation:
Global warming is a process that is occurring naturally, with or without human activity. This is not to say that humans don't have an impact, on contrary, the human activities have managed to add enough greenhouse gases in the atmosphere so that the process is speeded up, and that becomes very alarming because the changes are much faster.
Very often, the finger is pointed to the most developed countries in the world when it comes to greenhouse gas emissions like they are the only ones that contribute to it. This is far from true though. All of the well-developed countries, except for the US, have been investing heavily in environmentally friendly energy sources and have had a decrease in greenhouse emissions. On the other hand, countries like China, India, Indonesia, Pakistan, Nigeria, are all among the top polluters when it comes to greenhouse gases emissions. Now to be fair, the countries that are now well developed did a lot of harm in the past while they were developing, so it is hard to criticize the developing countries for wanting to become richer except if they are helped in sorting out the issue.
