On a recent survey, 40% of those surveyed indicated that they preferred walking to running. if 540 people preferred walking, how many people were surveyed

The Total number of people were surveyed is 1,350 people.

Step-by-step explanation:

Given as :

The total number of people who preferred walking = 540 people

The percentage of people who preferred walking to running = 40% of the total people

Let The Total number of people were surveyed = n people

Now, According to question

The total number of people who preferred walking = 40% of the total number of people were surveyed

Or, 40% of n = 540

Or, × n = 540

Or, n =

∴ n = 1350

So,Total number of people were surveyed = n = 1350 people

Hence,The Total number of people were surveyed is 1,350 people. Answer

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
