Answers

Answer 1

Answer:

A

Explanation:

Answer 2

Final answer:

The most accurate description of convection currents in Earth's mantle is hot air rising and cold air sinking, which is a process driven by differences in density due to temperature changes.

Explanation:

The description most comparable to the convection currents that exist in Earth’s mantle is hot air rising and cold air sinking. In the process of convection, which is critical for understanding plate tectonics in geography, warmer material becomes less dense and rises, while cooler material, being more dense, sinks. This is a principle that can be observed in several phenomena, including weather patterns, ocean currents, and the movement of tectonic plates due to mantle convection.

E.Keep the paragraph lengths short.
F.At the end, inform the readers if there are specific actions they need to take.

By the way guys this is more than one answer, i need this really soon, so as soon as possible please!

Answers

My answers are C, E, and F.

A memo is a note to particular people informing them of a new policy or telling them to do something. A memo needs to be short, straight to the point, and easy to read and understand. You should get to the point even before the memo starts in the “Action to Take” option. In the shortest space possible, keep the paragraph lengths very short (4 to 7 sentences typical). I might disagree with option D though. There should be at least two spaces between paragraphs or a blank line. However, the body of the memo should be single-spaced. The last line should tell what is needed or say exactly what action or actions you want taken.

Are high tech messages are always preferable to low tech messages

Answers

Yes very much so . The correct way to shut off the computer is to a. click stop. b. push the power button on the system unit. c. click start, then run, and then type shut down. d. click start and then shut down.

Choosing between high-tech and low-tech messages depends on the content, context, and the audience. Emails are better for detailed information, while texts are suitable for short messages. Low-tech methods can be reliable but less adaptable.

High-tech messages, like emails and texts, are integral parts of modern communication and are preferred for their speed and convenience. However, they may not effectively convey emotional tones or detailed information as well as face-to-face or phone conversations can. Different contexts may benefit from low-tech methods (like printed posters or letters) which are predictable and don't rely on technology that might fail.

Ultimately, the choice between high-tech and low-tech communication should consider the message's content, context, and the receiver's preferences.

Which formula would you use to round the number in cell b5 to the nearest 10? is it a b c or d?
a. mround(b5,10)
b.=mround(b5,10)
c.=mround: b5,10d.mround-b5>10

Answers

Final answer:

The correct formula to round the number in cell B5 to the nearest 10 is b. =MROUND(B5, 10), which uses the appropriate syntax for spreadsheet programs.

Explanation:

To round the number in cell B5 to the nearest 10 in a spreadsheet program, such as Microsoft Excel or G0ogle Sheets, you would use the formula that is correct syntax for these programs. The correct syntax for rounding a number to the nearest multiple of another number is =MROUND(B5, 10). So, the correct answer from the options provided is b. =MROUND(B5, 10).

When rounding off numbers in different contexts, the process slightly varies depending on the rules established for rounding in various scenarios. For instance, when dealing with decimals, you would round to the nearest place value dictated by the exercise or the desired level of precision. It is important to apply the correct rules of rounding, whether rounding up or rounding down, based on the digits impacted.

Final answer:

To round the number in cell B5 to the nearest 10, you would use the formula =MROUND(B5,10). This function, MROUND, rounds a number to a given multiple, and the syntax in option 'b' is correct for use in a spreadsheet.

Explanation:

To round the number in cell B5 to the nearest 10 in a spreadsheet application, you should use the formula with the correct syntax for the function which is:

=MROUND(B5,10)

This formula uses the MROUND function, which rounds a number to a specified multiple. In this case, 'B5' refers to the cell containing the number to be rounded, and '10' indicates the multiple to which you are rounding. Option 'b' in the provided choices is the correct formula. Here's a clarification of how the function works with different numbers:

0.028675 rounds up to 0.0287 (the dropped digit, 7, is greater than 5).18.3384 rounds down to 18.3 (the dropped digit, 3, is less than 5).6.8752 rounds up to 6.88 (the dropped digit is 5, and a nonzero digit follows it).92.85 rounds down to 92.8 (the dropped digit is 5, and the retained digit is even).

Seconds per megabit, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds.

Megabits per second, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds.

Answers

The best option and the one who explains itself better is the first option Megabits per second; because the independent quantity is time in seconds and dependent quantity is amount of data in megabits. In this case the dependent variable is the amount of data in megabits, something you can control, but time in seconds is indeed the independent variable.

Sharon is thinking about opening a bakery. She knows she wants to set her own hours, reduce her stress and make a profit. But she still has a lot to think through. Which of the following would NOT be a good early step?

Answers

Final answer:

The early step that would not be beneficial in opening a bakery for Sharon is neglecting the creation of a detailed business plan, which is crucial for financial understanding and overall business strategy.

Explanation:

Sharon is considering the essential early steps in opening her own bakery. One step that would not be a good early decision is to overlook the financial aspects, such as creating a detailed business plan. A business plan could help her understand the risks involved, the competition she may face, and the financial investment she'll need to make. To set her own hours, reduce stress, and make a profit, Sharon will need to consider her marketing strategy, location, supply costs, and potential customer base. Additionally, since entrepreneurs like Berkeley who are independent minded and hard working are successful because they plan and understand their business, Sharon should also consider the best business structure to suit her needs, such as a sole proprietorship or a limited liability company (LLC).

Final answer:

Choosing not to ignore financial realities is crucial for Sharon as she plans to open a bakery. Early steps should include market research and creating a business plan to ensure profitability and a good work-life balance.

Explanation:

Sharon is considering opening her own bakery and wants to set her own hours, reduce stress, and make a profit. An early step that would NOT be beneficial in her situation might be ignoring financial realities, such as the cost of supplies and potential profits or losses. A good early step for Sharon could include conducting market research, creating a business plan, and considering her financial position to ensure profitability.

For Sharon to succeed, she would also need to think about her desired work-life balance, considering the example of Shannelle, who realized the importance of making time for herself. Meanwhile, Berkeley's decision on business structure should be guided by the nature of her entrepreneurial venture, the risk she is willing to take, and whether she plans to operate independently or with partners. Lastly, a baker dealing with a probability distribution for his muffins must calculate to ensure there is neither an excess nor a shortage, which ties back to Sharon's need for thorough planning and understanding her market.
