It is a bad estimate because the gap between 712 and 589 is clearly (if you were just estimating in hundreds) would be 200
200 would be a better guess
Question 8:
Your choice is correct: two figures are similar if all correspondant sides are in the same ratio.
In your case, the figure on the right have correspondant sides which are all three times the figure on the left, since

So, the two figures are similar and their ratio is 1:3.
Question 9:
We follow exactly the same approach: let's see if the radii and the heights are in the same ratio: the radii are in ratio

While the heights are in ratio

So, the answer is again yes, they are similar, and the ratio is 1.6.
Answer:
m=11
Step-by-step explanation:
-6m-6=72
-6 on both sides to cancel it out
72 becomes 66
-6m=66
divide by -6 on both sides to cancel out
66÷6=11
m= 11
