A map is being reduced to from a pocket sized version. What is the scale factor being used to reduce the map?

Aneli [31]

Answer and explanation:

If a map is being reduced to form a pocket sized version then it is being proportionality reduced a smaller size that is required. Cartographers enlarge and reduce maps proportionally to serve different purposes in their study. The map is still the same but smaller in size.

If on a map 2cm represents 2 meters, that is 0.02/2 which evaluates to 1/100, then we are comparing distance and ensuring they are proportional using scale factor(our scale factor is 1:100 here)

8. Line AB passes through A(-2,4) and B(-8,-6).

netineya [11]

Answer:

AB : $\frac{5}{3}$

PT : $-\frac{1}{5}$

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be $\frac{4-(-6)}{-2-(-8)} =\frac{5}{3}$ (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be $\frac{-1-(-2)}{3-8} =-\frac{1}{5}$ . (Answer)

Here we have applied the formula of slope of a straight line passing through the points $(x_{1},y_{1})$ and $(x_{2},y_{2} )$ as given by $\frac{y_{1}-y_{2} }{x_{1}-x_{2} }$ .
