so for A it is 16 times as large because the area is 3*3 which is 9 but since it is a triangle the area is halved and is 4.5 and divide 72 by 4.5 which gives us 16
then for b I believe that the scale factor is 4
and for C it is asking for the bottom side of the scaled copy not of triangle A and 4*3=12 so the bottom is 12
ok now its complete =)
Recall that the perimeter of a polygon is the sum of the lengths of each side of the polygon.
Since a regular octagon has 8 sides of equal length, and the stop sign is a regular octagon with a side length of 12 in, then its perimeter is:

Simplifying the above result we get:

Answer:
$35.71
Step-by-step explanation:
Since Griffin’s General Store is having a 30% off sale on fans, it simply means that fans are paying for (100%-30%)= 70%.
Let the original price be x;
Therefore, 70% of x equal to $25;
70/100x = 25
0.7x = 25
x = 35. 71
(There ya go)
Answer: A: 90 degrees
Step-by-step explanation:
The measure of angle C is 90 degrees as BD and BC are chords to the circle.
Figure A maps to figure B with a scale factor of 2/3 -> Every single side of figure B equal to 2/3 of its corresponding side on triangle A.
So, we can find x by taking 10.5 x 2/3 = 7
-> x = 7
