A scale factor (<em>k</em>) is a number by which the size of any geometrical figure or shape can change:
• If the image is ,enlarged,, then the ,scale factor is more than one (,k > 1,).
,
• If the image is ,contracted,, then the ,scale factor is less than one (0 < k < 1).
Then, the smaller the scale factor, the smaller the figure. In our case, the options given are:
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%3C%5Cfrac%7B1%7D%7B2%7D%3C%5Cfrac%7B3%7D%7B4%7D)
And if we evaluate the size of the dilated figures, we can see that:
[tex]BA is the biggest while B is the smallest.
Then we can suppose the scale factors.
Answer:
• A goes with 3/4
,
• C goes with 1/2
,
• B goes with 1/4
Yards = miles × 1760
2.3 × 1760= 4048
2.3 miles into yards: 4048 yards
2/25 because since there are 2 #'s after the decimal you know that the denominator in 100. find the common factor which in this case is 4 and divide both the numerator and denominator by the common factor to simplify
