Which appears to harder that what it is
It looks like a similar triagle solution
$\dfrac{800}{7000}=\dfrac{x}{1400}$
actually the answer istkhunny said:800/7000 = x/1400
It's a little bit of smoke.
80/700 = x/1400
8/70 = x/1400
8/7 = x/140
8/1 = x/20
Look easier?
Anyone whose first move is to produce 112,000 = 700x simply isn't paying attention.
The GRE (Graduate Record Examination) is a standardized test that is often required for admission into graduate programs in various fields, including science. It measures verbal reasoning, quantitative reasoning, and analytical writing skills, and is used by universities to assess a candidate's potential for success in graduate-level studies.
"Ge.2 similar triangles" refers to the concept of geometric similarity, where two triangles have the same shape but different sizes. This concept is relevant to science, particularly in fields such as physics and engineering, where understanding the relationship between similar shapes and their properties is important for solving problems and making predictions.
The concept of similar triangles can be applied in various ways in scientific research. For example, in physics, it can be used to analyze the forces acting on an object and predict its motion. In biology, it can be used to study the relationship between different organisms and their structures. In chemistry, it can be used to understand the molecular structure of compounds.
Yes, there are many real-life examples of similar triangles in nature. One common example is the relationship between a tree and its shadow. The shape of the shadow is similar to the shape of the tree, but it is smaller in size. Another example is the similarity between different species of birds, where their body structures are similar but their sizes may vary.
Understanding the concept of similar triangles can benefit scientists in various ways. It can help them make accurate measurements and predictions, analyze complex systems, and develop new theories and models. Additionally, it can also aid in communication and collaboration with other scientists, as it provides a common language and framework for understanding geometric relationships.
