It means that every 2 cm on the map would represent 5 miles in the real world.
A scale factor is a number which scales, or multiplies, some quantity. A scale factor of two would mean to multiply whatever it is by two.
i have no clue
The mean and scale will change by the factor of change for the sample data.
times by two
Assuming you mean "two and a half inches"? The answer is 1000 miles
Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.
If you mean: 8 12 16 and 10 15 20 then it is 4 to 5
it deals with proportion. think of a map ... it has a "scale". it would be silly to try and create a life-size map of a city, because it would cover the whole city. instead, they might use a "scale" to say that each inch on the map represents 1 mile in real life. a model airplane might have a scale of 1:30 meaning that if every measurement on the model were multiplied by 30, then it would be the size of the real thing. if you scale something by a factor of 10, you make everything 10 times bigger (or further) a scale factor of 1/10 makes everything 10 times smaller.
200,000 miles is equivalent to 321,868.8 kilometers. To convert miles to kilometers, you would multiply the number of miles by 1.60934. This conversion factor is based on the international agreement on the exact length of a mile.
the number used to muliplpy the lengths of a figure to stretch or shrink it to a similar image.
Scaling up a ratio means increasing both parts of the ratio by the same factor to maintain the proportional relationship. For example, if the ratio is 2:3 and you scale it up by 2, the new ratio would be 4:6.
The scale on the map is a ratio of real size to that on the map, Say you see a scale that says 1:50 miles, That is telling you that for every 1 inch or cm (depending on the map) is 50 miles in real life. It's to help you get an idea of how far a place is by comparing it to another.
