# Write a scale factor

Use a low compression ratio. Medium Use a medium compression ratio. High Use a high compression ratio. This means that Unity can access the mesh data at run time, and you can access it from your scripts. You should understand the logic behind how these are used and how they should appear on real topographic maps. On your upcoming lab exam, you should also be able to convert one type of map scale into another, and calculate size differences scale factor, area factor between different maps.

The MAP unit is always mentioned write a scale factor. A mixture of map and land units makes the verbal scale difficult to compare between different maps - it must be converted first to a Representative Fraction see below. Doing so will change the numerical relationship of the R.

The graphic scale is a bar chart or "ruler" that is drawn at the bottom of a topographic map. This is the scale that you should use when asked to measure distances on the map. Note that the zero mark is not located at the left end of the graphic scale.

You may measure distances by marking off the 2 end points on the edge of a sheet of paper and aligning the edge of the paper against the graphic scale make sure one of your marks is on the zero. When converting a verbal scale to an R. That is the basic difference between these two types of map scales.

Decide which ONE unit to convert to: To become an R. You have 2 choices to choose from: It is usually easier to convert from a larger to a smaller unit "how many inches are in a mile? So, we will then convert the "1 mile of land" to "X number of inches". Eliminate the unwanted unit by multiplication: One of the basic rules of algebra is that any number or unit divided by itself equals 1.

If you started with miles and wanted to get rid of miles and end up with inches, how do you do this?

## Scale Factors

First, get rid of "miles" by multiplying it by a fraction that contains "miles" in the denominator, and an equivalent number of smaller units in the numerator. You may not know how many inches there are in a mile, but you should know that there are 5, feet in a mile. This will get rid of miles, but will leave you with "feet" which is still not the same unit as the Map Unit inches. To get to inches, get rid of "feet" by multiplying by a fraction that contains "feet" in the denominator and the equivalent number of inches in the numerator:Lesson cont’d Check for Understanding Ask the students to write a description of a scale factor in their own words.

Students will share their descriptions with their partner and the. Scale Factor Unity’s physics system expects 1 meter in the game world to be 1 unit in the imported file. If you prefer to model at a different scale, then you can compensate for it here. Use File Scale Use the model scaling defined in the model file, or uncheck to set a custom Scale Factor value. Evolution of the Scale Factor Mike Specian gave evolution of the scale factor for single component models, however, in general we do the following: Write Friedmann equations in terms of .

Dilations Worksheet Name State whether a dilation with the given scale factor is a reduction or an enlargement. 1.k=3 4. k CJI lawmen Determine whether the dilation from Figure A to Figure B is a reduction or an enlargement.

Scale Factor 1. A drawing of a box has dimensions of 2 inches, 3 inches, and 5 inches. The demensions of the actual box will be times the dimensions in the drawing. In Euclidean geometry, uniform scaling (or isotropic scaling) is a linear transformation that enlarges (increases) or shrinks (diminishes) objects by . To perform dilations, a scale factor and a center of dilation are needed. If the scale factor is larger than 1, the image is larger than the original; if the scale factor is less than 1, .

Using engineering scales. Scale the original border down by this amount and your scale is changed. The Ratio and Decimal numbers can be helpful if you are working in paper space and need to know what the scale factors are for window resizing in order to create the proper scale.

Describe one as a scale drawing of the other and ask the student to write the scale factor for each pair. Ask the student to calculate the area of each polygon and then write the scale factors and the ratios of areas side-by-side (e.g., , ; , ; , ).
