Answer:
D. (x, y) →
Step-by-step explanation:
A dilation is a transformation which reproduces an image of the same shape as the original, but might be of a different size.
When the dilation produces a smaller image is called a reduction.
Mathematically, a reduction occurs whenever the scale factor is between 0 and 1.
Out of the options, the only one that has a scale factor less than one is:
(x, y) →
Since the scale factor is 1/2 which is less than 1.
All other options are not reductions.
Answer:
Part A: 6a = 10.5 and a = 1.75 meters.
Part B: $3.87.
Step-by-step explanation:
Part A: Diego draws a hexagon with a perimeter of 10.5 meters and each side of the hexagon is the same length.
Now, the hexagon has 6 sides and if each side is of length 'a' meters, then the equation that models the situation is
6a = 10.5 ......... (1) (Answer)
⇒ a = 1.75 meters. (Answer)
Part B:
The total cost of supplies to paint the mural is $38.70. Diego and 9 friends divide the cost equally.
Hence, the total cost will be divided into 10 persons.
Therefore, each person will get dollars. (Answer)
