Answer:

The total number of people surveyed is 193.

Step-by-step explanation:

Let us assume the total number of people surveyed = k

The percentage of people who found the  price reasonable  = 85%

The number of people who found the  price reasonable  = 164

So, the 85 % of total people who were surveyed is 164.

⇒ 85 % of  k = 164

or, \frac{85}{100}  \times k = 164\\\implies  k = \frac{164 \times 100}{85}  = 192.9 = 193

⇒ <u>k = 193</u>

<u />

Hence, the total number of people surveyed is 193.

In the figure to the right, AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3 /10 cm. Find the perimeter of the fig
pentagon [3]

Answer:

The perimeter of the figure = 9.5 cm

Step-by-step explanation:

<em>Note: You probably missed to add the figure, but after a little research I found and am attaching the figure. I have answered your question based on the reference of that figure. But, I hope you would learn the concept so that you could solve any question based on this concept. So, please check the figure.</em>

<em>Solution:</em>

The perimeter of the figure is the sum of all the sides of the given figure as shown in the attached figure.

So, here is the formula to calculate the perimeter.

                <em>Perimeter </em>=<em> AB + DE + BC + AE + BC  </em>

As AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm

Therefore,

<em>Perimeter</em> = 1 3/4  + 1 1/4  + 13/10 + 1 1/5           ∵ AE + BC = 1 1/5

                                   = (130  + 110  + 52 + 88) / 40

                                   = 380/40  

                                   = 9.5 cm

So, the perimeter of the figure is = 9.5 cm
