lisabon 2012 [21]

Answer:

No, those ratios are not proportional.

Step-by-step explanation:

The reason for them not being proportional is because 2/5 is already in its simplest form and 40/16 in its simplest form is 5/2, resulting in them not being equivalent meaning that they are not proportional.

Saquina dilates a digital photograph by a factor of 1.75 to create a new digital photograph similar to her original photograph.
KATRIN_1 [288]

Answer

Perimeter = 1.75 times larger

Area = 3.0625 times larger

Step-by-step explanation:

Let the original quadrilateral have sides of a, b, c, d

Perimeter of the New Photograph

  • Then the perimeter of the original is P = (a + b + c + d)
  • Now the perimeter of the new quad is P = 1.75a + 1.75b + 1.75c + 1.75d
  • Using the distributive Property we get P = 1.75(a + b + c + d) So the new perimeter is 1.75*the old perimeter.

Area of the New Photograph

The area is a little harder. Suppose the Old figure had an Area found by the formula of

  • Area = e * f   Each measurement is increased by a factor of 1.75
  • Area_new = 1.75e * 1.75f
  • Area_new = 3.0625 * e * f
  • Area_new = 3.0625 * old area
