Answer:

p=50t

Step-by-step explanation:

The more pages Crystal has to read, the more time she spends reading.

Let p=number of pages read

t=time spent reading the number of pages

As t increases, p increases.

This is a direct proportion and we can write it as:

p=tk$ where k is the constant of proportionality\\When $ t=\frac{1}{2} $ hour, p=25 pages\\Therefore:\\25=0.5k\\k=25\div 0.5\\k=50

Substitution of k into p=tk gives:

p=50t

Therefore, an equation representing the relationship between the number of pages Crystal reads and how much time she spends reading is:

p=50t

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.

AfilCa [17]

Answer:

126 square miles

Step-by-step explanation:

So I just draw a grid and mark the thingies (sorry my math vocabulary is not very good)

So you get a rectangle that is 5x9 if you connect the dot thingies and 9 square units is 14 square miles and 9x14=126. Using a coordinate grid makes it easier to visualize what you’re doing
