There's no dot plot.
Step-by-step explanation:
I'll answer it if you can give me a picture though...
Answer: (A) Yes
Step-by-step explanation:
Let us look at the side lengths. When we are talking about scale copies, the lengths should stay proportionate from the original shape to the copy.
Both of the figures are triangles. I will be looking at the length of their legs. Figure A has leg lengths of 4 and 3. Figure B has leg lengths of 8 and 6, respectively.
This means Figure B <em>is</em> a scale copy of Figure A because 8/4=2 and 6/3=2. These mean the proportions stayed similar.
Answer:
The length is 7.2 feet.
Step-by-step explanation:
It is a ratio of 10:18. Therefore you can simplify the ratio to 18/10 or 1.8. This then becomes 4 (width) times 1.8, or 7.2 feet. :)

Warning: This might be rough...
First draw it out. Label the angles at the corners of the triangle 60 (definition of equilateral triangles). Now draw a line from the center of the circle to the corner, splitting the corner in half. Label this line R and a corner as 30 degrees. No to find the height of this triangle, you do rsin(30). The base of this triangle is 2rcos(30). Now find the area of this mini triangle (rsin(30)*2rcos(30)/2=r/2*rsqrt(3)/2=r^2sqrt(3)/4). Now multiply this by 3 because you have 3 mini triangles... to get...
