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:
11/8 or 1 3/8 or 1.375
Step-by-step explanation:
From the information given by the question, we can form an equation:
Let us call the number 'n'
8 × n - 7 = 4
We then move the 7 to the other side, changing it from minus to plus:
8 × n = 4 + 7
So,
8 × n = 11
We divide both sides by 8, to leave n on one side of the equation.
n = 11/8
Therefore, n = 11/8 or 1 3/8 or 1.375
Answer:
We conclude that 0.3 pounds of trail mix are in each bag.
Step-by-step explanation:
We know that Vance combined 2 \frac{13}{15} pounds of peanuts with 1 \frac{1}{3} pound of raisins to create trail mix, then equally distributed the mix into 14 bags. We have:

we get

We conclude that 0.3 pounds of trail mix are in each bag.
