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

Jenna is deciding between two cell-phone plans. The first plan has $50 signup fee and costs $20 per month .The second plan has $
olasank [31]

Answer:

Step-by-step explanation:

Let x represent the number if months it will take for the total costs of both plans to be the same.

The first plan has $50 signup fee and costs $20 per month. This means that the total cost of using the first plan in a month would be

20x + 50

The second plan has $30 sign up fee and cost $25 per month. This means that the total cost of using the first plan in a month would be

25x + 30

For the costs to be the same,

20x + 50 = 25x + 30

25x - 20x = 50 - 30

5x = 20

x = 20/5 = 4

The costs would be the sane after 4 months. The cost would be

20 × 4 + 50

= $130
