Question
In the 1908 Olympic Games, the Olympic marathon was lengthened from 40 kilometers to approximately 42 kilometers. Of the following, which is closest to the increase in the distance of the Olympic marathon, in miles? (1 mile is approximately 1.6 kilometers.)
- 1.00
- 1.25
- 1.50
- 1.75
The correct answer is: 1.25
It is given that , In 1908, the marathon was lengthened to 42 kilometers from 40 kilometers.
i.e. 42 – 40 = 2 kilometers
Since 1 mile is approximately 1.6 kilometers,
1 mile = 1.6 km
Let x be the miles equal to 2 km
x = 2 km
the increase of 2 kilometers can be converted to miles by multiplying as
2 kilometers ×( 1 mile / 1.6 kilometers) = x miles
Therefore, x = 1.25 miles
Note:- Choices A, C, and D are incorrect and may result from errors made when applying the conversion rate or other computational errors.

A polling agency recently surveyed 1,000 adults who were selected at random from a large city and asked each of the adults, “Are you satisfied with the quality of air in the city?” Of those surveyed, 78 percent responded that they were satisfied with the quality of air in the city. Based on the results of the survey, which of the following statements must be true?
I. Of all adults in the city, 78 percent are satisfied with the quality of air in the city.
II. If another 1,000 adults selected at random from the city were surveyed, 78 percent of them would report they are satisfied with the quality of air in the city.
III. If 1,000 adults selected at random from a different city were surveyed, 78 percent of them would report they are satisfied with the quality of air in the city.
In mathematics, a survey is a technique for gathering data that involves posing a series of questions to participants to learn more about their attitudes and behaviors. It is the most typical and affordable method of data collection.

The formula above is used to estimate the ideal quantity, Q, of items a store manager needs to order given the demand quantity, d; the setup cost per order, K; and the storage cost per item, h. Which of the following correctly expresses the storage cost per item in terms of the other variables?
Note:
Whenever there is an equation with a square root involved, first we try to remove that square root to get a clear picture of the equation. It is easier to operate on an equation with no square roots or log or inverse.
