What do you think Thomas Edison meant by the word perspiration? How do those words apply to what you've learned about businesses
EastWind [94]

1. Thomas Edison used "perspiration" to refer to the physical and mental efforts needed to achieve a meaningful purpose in any human endeavor.

2. As it applies to businesses, it is not enough to develop a business idea or plan, as the business person must be prepared to execute and carry the business idea or plan to fruition.

<h3>What does Thomas Edison's reference mean?</h3>

According to Thomas Edison, the superior intellect or creativity we associate with great minds comes from inspiration (the idea) and perspiration (hard work).

Perspiration literarily refers to the sweat that emanates as someone works hard.

Without a strong working ethic, it will be impossible to achieve great results from only the proposition of great ideas or business plans.

A number is greater than 50 and less than 85 the number has 13 and 3 as factors
alina1380 [7]

Answer:

The Answer is: 78.

Step-by-step explanation:

This one makes you think!

Let n = the number.

The number is greater than 50 and less than 85:

50 < n < 85

Some of the factors are 13 and 3.

So, multiply 13 * 3 = 39.

Multiply again by 2:

39 * 2 = 78.

78 can be factored as:

13 * 3 * 2 = 78, and it is greater than 50 and less than 85.

The number is 78.

Hope this helps! Have an Awesome Day!! :-)
