are any two regular polygons similar. The area of the smaller figure is about 390 cm^2. choose the best estimate of the area of

galben [10]

Answer:

The best estimate of the area of the larger figure is $693\ cm^{2}$

Step-by-step explanation:

step 1

<em>Find the scale factor</em>

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x-----> the corresponding side of the larger figure

y-----> the corresponding side of the smaller figure

$z=\frac{x}{y}$

we have

$x=12\ cm$

$y=9\ cm$

substitute

$z=\frac{12}{9}=\frac{4}{3}$ -----> the scale factor

step 2

<em>Find the area of the larger figure</em>

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x-----> the area of the larger figure

y-----> the area of the smaller figure

$z^{2}=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=390\ cm^{2}$

substitute and solve for x

$(\frac{4}{3})^{2}=\frac{x}{390}$

$(\frac{16}{9})=\frac{x}{390}$

$x=390*16/9=693.33\ cm^{2}$

If a restaurant sells 6,000 meals in one month, at an average price of 17 per meal for the customer and an average cost of $4.60

mash [69]

Answer:

The percentage increase from the restaurant price to the restaurant cost = 269.56%

Step-by-step explanation:

An average price of per meal for the customer= $17

An average cost of per meal for the restaurant= $4.60

Difference in price = 17-4.60

Difference in price = $12.4

So, the percentage increase from the restaurant price to the restaurant cost = $\frac{12.4}{4.60} \times 100$

The percentage increase from the restaurant price to the restaurant cost = 269.56%
