It wouldnt be reasonable bc a scale factor of 1 would make no difference therefore meaning there is no dilation.

6. Describe some things you could notice in two polygons that would help you decide

Goshia [24]

Answer:

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase.

Step-by-step explanation:

In this question, we need to tell some things that could help to check if two polygons are scaled copy of each other or not.

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase. For example, if a rectangle has a length of 10 and a height of 8, a scaled copy would be a length of 5 and a breadth of 4.

Another example is as follows:

If a rectangle has a length of 4 and a height of 3, a scaled copy would be a length of 8 and a breadth of 6.

Margaret [11]

Answer:

Step-by-step explanation:

Given that At the pet owner’s meeting, there are 20 people who own dog, and 35people who own cat and 9 people own goldfish. Some people own both catand dog and some people own both gold fish and cat. No dog owners owngoldfish. There are twice as many people who own both goldfish and catthan people who own both dog and cat.

Total no of people =52

The venn diagram attached gives a clear picture

assuming x to be owners of both dog and cat. Then 2x is for both goldfish and cats.

Totalling all mutually exclusive we get

64-3x=52

x=4

No of owners who own both cat and dog =4
