Answer:
40,000 is 39,265 rounded to the nearest ten thousands
Step-by-step explanation:
Answer: Choice C) 36:25
To get this answer, we simply square each piece of the original ratio 6:5
6^2 = 36
5^2 = 25
Think of two squares where one has a side length of 6 and the other of 5. The ratio of the sides is 6:5. The areas of the two squares are 36 and 25 as mentioned above. So the ratio is 36:25. This idea can be applied to any surface area or area in general. It doesn't have to be two squares. The reason why we can apply this to any general shape is because we can break up the shape into small squares to get a rough approximation. The more squares we use, the better the approximation.
Answer:
Your second answer, otherwise know as 1 in. : 4ft. is the answer.
Step-by-step explanation:
The new map is 3 times bigger than the old map, therefore your given scale for the first map will shrink by 3 to compensate for the new map being bigger. Divide 12ft by 3 and you get 4 ft., so your answer is 1in. : 4ft.
It would be 2.5E-2 or with the power of 10 it would be 2.5 x 10^-2
