The picture in the attached figure
we know that
a) find the ratio of the perimeters
the ratio of the perimeters is equal to the scale factor
scale factor=26/6-----> 13/3
the answer Part a) isthe ratio of the perimeters is 13/3
b) find the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]²*area smaller figure
scale factor²=area larger figure/area smaller figure
the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9
the answer Part b) is 169/9
the complete answer is
13/3 and 169/9
Answer:
2x+1y=15
Step-by-step explanation:
I don't think it needs explaining but it won't let me anwser without
Answer:
No, you are not correct.
It should look like this:
Prefer colorful decorations Prefer neutral decorations
Pay attention 20 25
to fashion
Do not pay
attention to 72 33
fashion
Step-by-step explanation:
33 is 22% of 150. In the question it states that 70% of people do not pay attention to fashion. We need to find the other 48% here. In order to do that we multiply .48 by 150. That gets us 72. To check that answer you can add both 72 and 33 and then divide by 150, which gets 70%.
To get the amount of people that prefer neutral decorations and pay attention to fashion we need to add up 20 + 72 + 33 and that equals 125. Next, we take 150 and minus 125 of it to get 25.
