Step-by-step explanation:

Cube root the volume of the room (6859) which equals 19. do 19x2=361. Do 361x5=1805. So the total would be $1805 i believe

Explain how to convert 2.7 × 104 from scientific notation to standard form, then give the answer in standard form.

Answers

The exponent positive 4 means we move the decimal four spaces to the right.

The 2.7 becomes 27,000 after doing so

[tex]2.7 \times 10^4 = 27,000[/tex]

If the exponent was negative, then we would move the decimal point to the left.

When converting scientific notation to standard form you will move the decimal the number of times that is shown in the exponent which in this case is 4. So , you move the decimal to the right since it is a positive 4 then that would give you the number 27,000 which is in standard form.

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.

Answers

Answer:

Down Below :))

Step-by-step explanation:

This is quite simple.

Take a look at both of the numbers, see how their both 29?

Subtracting 29 - 29 = 0

Explanation: The average temperature was 0 because when subtracting 29 - 29, it gives you 0.

The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.

If m is a positive integer, what is the least value of m for which 180 is a factor of 105m

Answers

Answer:

Step-by-step explanation:

If 180 is the factor of 105 m, then the factors of 180 should also be the factors of 105 m.

Factors of 180 = 15 * 12

Factors of 105 m = 15 * 7 * m

The least value of m is  = 12

The answer is 12 as
15*12 is 108
So m=12

The width of the playhouse is 22 centimeters and the height is 10 centimeters. Not drawn to scale The yard space is large enough to have a playhouse that has a width of 3.5 meters. If Parker wants to keep the playhouse in proportion to the model, what cross multiplication of the proportion should he use to find the height?

An excerpt from The Adventures of Huckleberry Finn Mark Twain 1 You don't know about me without you have read a book by the name of The Adventures of Tom Sawyer; but that ain't no matter. That book was made by Mr. Mark Twain, and he told the truth, mainly. There was things which he stretched, but mainly he told the truth. That is nothing. I never seen anybody but lied one time or another, without it was Aunt Polly, or the widow, or maybe Mary. Aunt Polly--Tom's Aunt Polly, she is--and Mary, and the Widow Douglas is all told about in that book, which is mostly a true book, with some stretchers, as I said before. 2 Now the way that the book winds up is this: Tom and me found the money that the robbers hid in the cave, and it made us rich. We got six thousand dollars apiece--all gold. It was an awful sight of money when it was piled up. Well, Judge Thatcher he took it and put it out at interest, and it fetched us a dollar a day apiece all the year round --more than a body could tell what to do with. The Widow Douglas she took me for her son, and allowed she would sivilize me; but it was rough living in the house all the time, considering how dismal regular and decent the widow was in all her ways; and so when I couldn't stand it no longer I lit out. I got into my old rags and my sugar-hogshead again, and was free and satisfied. But Tom Sawyer he hunted me up and said he was going to start a band of robbers, and I might join if I would go back to the widow and be respectable. So I went back.
