8. For questions 8-9, determine whether the two figures are similar. If so, give the scale factor of the smaller figure to the l
Vinvika [58]

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

12 = 4\times 3, 21 = 7\times 3, 54 = 18\times 3

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

\cfrac{3.2}{2} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}

While the heights are in ratio

\cfrac{6.4}{4} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}

So, the answer is again yes, they are similar, and the ratio is 1.6.

Seven less than the product of 8 and a number equals 4
Vlad1618 [11]

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

Inessa [10]

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:

2+\frac{13}{15}+1+\frac{1}{3}=3+\frac{18}{15}\\\\=4+\frac{3}{15}=\frac{63}{15}

we get

\frac{\frac{63}{15}}{\frac{14}{1}}=\frac{63\cdot 1}{15\cdot 14 }=0.3

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