How can you decide whether to be a brain surgeon or a novelist

Answers

Hey there! Hello!

Wow, loaded question... I'm assuming that this falls under a more personal category for you, but if not, I'd really like to know what class your taking that's asking you a question of this caliber. 

I'm afraid that I cannot answer your question, directly anyway. I'm not you, and I don't know you personally; even if I did, I still wouldn't be able to tell you what to do with your life. 

Things like these are tough. I've wanted to be an artist my whole life, but just recently, I've been considering other options due to the lack of money involved generally with being an artist, and doing something related to space. But, things like this aren't exactly the easiest to go back on. A college I would go to for a doctorate in space science would be the polar opposite to one I would go to for a major in motion design and a minor in illustration. The transition from one to the other would be quite hellish, and I'll probably feel regret with either one I go for when I find myself thinking of what I could have been instead of what I am.

But it's loaded questions like these that make us humans have to consider how we see ourselves in the future. I can see myself as either a space scientist or a motion/graphic designer. I wish I could be both, but I can't imagine I could pay for more than 10 years of college just so I can do it all. 

The only thing I can really recommend is to sit on it for as long as you can. It's not procrastinating, only putting deep consideration into your options. I'm not sure how long you have until you need to make the college/career decision, but as someone with only two years until I have to go to college, I know how stressful it can be. Two years seem to be flying by like 2 minutes when thinking about my future. 

Also, which class do you like better? Do you like science related to anatomy, like Biology, more, or do you like English, and enjoy when you get to write essays and short stories for your assignments more?

Another thing I can suggest is writing down the benefits to either profession as well as the drawbacks. Make sure your drawbacks do not include not being able to do the other profession, or you'll send yourself into some subconscious, paradox–induced panic attack, and we don't want that to happen. Think about what you'll be able to do in the world with either profession. Which of these accomplishments is more important to you? Be sure to also consider how much you'll be able to make in each profession, since your future self will thank you a lot for it later. Just do as much research about either profession as you can. 

There are a lot of factors to consider when choosing a profession, but make sure, in your final decision, that you choose something that you know you'll love and will never regret doing. I'm sure it wouldn't hurt to talk with a trusted parent or loved one about this decision, as well. 

I hope this helped you out! I know how it feels to be in such turmoil over things like this, where the outcome can be so unpredictable. But thank you for reading this all the way through if you got to the end, and feel free to ask me any additional questions if you have any. :-)

Choosing between a career as a brain surgeon and a novelist involves weighing the time commitment for education and training against immediate earning potential. Additionally, personal passion, societal impact, and job significance in relation to one's lifestyle should be considered. The value of a career isn't solely determined by financial gain or status.

Deciding between becoming a brain surgeon or a novelist involves considerations beyond immediate income. The hypothetical scenario emphasizes that both professions, in this case, pay $150,000 annually, with a key difference in time invested in education and training. A brain surgeon requires extensive education and does not begin earning until about age 35, whereas a shoe shiner, used metaphorically for immediate income jobs like novel writing, earns from age 16. This leads to an opportunity cost of $2.85 million over 19 years.

However, career decisions are not solely based on financial aspects. They require considering personal interests, skills, and societal needs. A brain surgeon's job is highly specialized, and few people possess the necessary skills, which warrants a high income as an incentive. Conversely, a novelist's path may allow more immediate creative expression and potentially earlier financial independence.

It's essential to consider long-term consequences and uncertainties in career choice. Your passion, societal impact, and desired lifestyle must all shape your decision. Moreover, the intrinsic value of different professions cannot be solely quantified by income or prestige. Jobs like brain surgery or coal mining are both critical, and their importance is context-dependent.

An airplane travels 2748 miles in 6 hours.How far would they travel in 2 hours?

Answers

you can set up a proportion in order to get this answer. So if you're able to travel 2748 miles in 6 hours, then divide 2748 by 3  in order to get the distance for 2 hours. This should be equal to 916 miles in 2 hours.
Divide 2748 by 6 to find how much miles it travels in one hour. Then multiply that answer by 2 to find the total amount of miles traveled for 2 hours.

A student earns a 98 on a test for answering one question incorrectly and earns a 90 for answering five questions incorrectly. Is the slope of the line that models the linear relationship a positive negative zero or undefined slope?

Answers

Answer:

Negative Slope

Step-by-step explanation:

The slope is the ratio of Change in height to the change in horizontal distance. It can also be define as tangent of angle made by that line and it is find by formula, [tex]slope (m)= \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

The slope is said to be a positive slope when a line is moving from left to right, the line rises.

The slope is said to be a negative slope when a line is moving from left to right, the line falls.

Here, Let the student earns be y marks in test

and let incorrect question be x

then y₁ = 98 , y₂ = 90 and x₁ = 1 , x₂ = 5

then [tex]slope (m)= \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

[tex]slope (m)= \frac{90 - 98}{5 - 1} [/tex]

⇒ m = -2

Hence, it has negative slope.

Evaluate 5/9(f-32)
when f=50

Answers

Final answer:

To evaluate 5/9(f-32) when f=50, substitute 50 into the expression, simplify the bracket (50 - 32 = 18), and then multiply the result by 5/9. This simplifies to 18/9 (which is 2), and then 2 x 5, yielding a final answer of 10 degrees Celsius.

Explanation:

To evaluate the expression 5/9(f-32) when f=50, you need to plug the value of f into the expression and then simplify it.

Here are the steps:

Substitute 50 for f in the expression: (5/9) × (50 - 32).

Calculate the bracket first: 50 - 32 = 18.

Multiply the result by 5/9: (5/9) × 18.

Divide 18 by 9, which gives you 2.

Finally, multiply 2 by 5, which gives you 10.

Therefore, 5/9(f-32) evaluated at f=50 is 10 degrees Celsius.

What is the relationship between the 5s in the number 755,371

Answers

The value of 5 in the ten-thousands place is 10 times greater than the value of 5 in the thousands place.
You can also say that the value of 5 in the thousands place is 10 times less than the value of 5 in the ten-thousands place.
Final answer:

The 5s in the number 755,371 represent different values due to their place in the number. The first 5 represents 50,000 as it is in the 'tens of thousands' place, while the second 5 represents 500 because it is in the 'hundreds' place.

Explanation:

The relationship between the two 5s in the number 755,371 is dictated by their place values in the number. The first 5, which is the second digit in the number, is in the 'tens of thousands' place, therefore representing 50,000. The second 5, which is the fourth digit in the number, is situated in the 'hundreds' place, therefore representing 500. Despite being the same digit, their value varies greatly because of their place in the number. This concept of

The total money y Aaron earned mowing x lawns is showns by the equation y= 15x+25. What does the slope represent?

Answers

Final answer:

The slope in the equation y = 15x + 25 represents the rate at which Aaron's earnings increase per lawn mowed, which is $15 for each additional lawn.

Explanation:

In the equation y = 15x + 25, the slope is represented by the coefficient of x, which is 15. The slope indicates the rate at which Aaron's total earnings increase for each additional lawn he mows. Specifically, the slope value of 15 means that Aaron earns $15 for each lawn he mows. The y-intercept of the equation is 25, which represents a starting value or a fixed amount that does not depend on the number of lawns mowed. This indicates that Aaron might have a base charge or initial fee of $25 before he starts mowing any lawns.

Final answer:

The slope in the equation y = 15x + 25 indicates Aaron earns $15 for each lawn he mows. The slope is the rate of change between lawns mowed (independent variable) and money earned (dependent variable).

Explanation:

The slope in the equation y = 15x + 25 represents the amount of money Aaron earns per lawn he mows. In this equation, the slope is 15, which means that Aaron earns $15 for each lawn he mows. The y-intercept in this context is 25, which typically would represent an initial fee or starting amount, but since it relates to lawns mowed, it may not have a contextually relevant interpretation without additional information. In general, the slope in a linear equation like this contextualizes the rate of change between the independent variable (lawns mowed) and the dependent variable (total money earned).

what is (3.5×10^4)^2 in scientific notation with 4 significant digits?

Answers

Well, let's first square 3.5x10^4 which is 1,225,000,000

Scientific notation is when you put a decimal place after the first digit and then say the answer is that multiplied by 10 to a power. This power is the number of digits that come after the first. In this case, the power should be 9 (if you count the 225 and all the 0's, you'll count 9 numbers).

Thus the answer is 1.225x10^9

What is 10/30 simplified?

Answers

1/3 Good luck with other questions!

To simplify the fraction 10/30, divide both the numerator and the denominator by their greatest common divisor, which is 10, resulting in the simplified fraction 1/3.

Simplifying the Fraction 10/30

To simplify the fraction 10/30, we want to find the greatest common divisor (GCD) that both the numerator (10) and the denominator (30) share. In this case, both numbers are divisible by 10. So, we divide both parts of the fraction by 10 to find the simplest form.

Step 1: Divide the numerator by 10.
10 / 10 = 1

Step 2: Divide the denominator by 10.
30 / 10 = 3

Therefore, the simplified form of the fraction 10/30 is 1/3. As we recall from our Algebra classes, this is a legal maneuver because multiplying or dividing by a fraction equivalent to 1 (like 10/10) does not change the value of the original fraction. It only simplifies it. So, the simplified fraction of 10/30 is indeed 1/3.
