The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet. Cameron determines the area of the wall to

be 1423.125 square feet. Which best explains the reasonableness of Cameron’s solution? Cameron’s solution is reasonable because there are four decimal places in the factors and four decimal places in the product. Cameron’s solution is reasonable because there are three decimal places in the factors and three decimal places in the product. Cameron’s solution is unreasonable because mc023-1.jpg is 153, and 153 is not close to his product. Cameron’s solution is unreasonable because mc023-2.jpg is 100, and 100 is not close to his product.

Response:

Cameron's answer is not justifiable, as it should show four decimal places instead of three.

Detailed explanation:

To find the area of the rectangular wall, we multiply 16.5ft by 8.625ft; observing that we indeed have a total of four decimal points. The result of the multiplication is 142.3125. Therefore, Cameron's calculation is flawed because he only used three decimal points rather than the required four.

16.5ft(8.625ft)=142.3125ft^{2}

.580 80 repeating as fraction
Svet_ta [12734]
To start, we will shift the non-repeating segment of the decimal to the left side by dividing by a power of 10.

Then we will assign a variable to represent the value and also shift the repeating segment to the left.

Essentially, the concept here is that we can denote the repeating portion with a variable, let's say "x", and move forward with the calculation;

\bf 0.580\overline{80}\implies \boxed{\cfrac{5.80\overline{80}}{10}}\qquad \textit{now, let's say }x= 5.80\overline{80}\\\\
-------------------------------

\bf thus\qquad \begin{array}{llll}
100\cdot x&=&580.80\overline{80}\\
&&575+5.80\overline{80}\\
&&575+x
\end{array}\qquad \implies 100x=575+x
\\\\\\
99x=575\implies x=\cfrac{575}{99}\qquad therefore\qquad \boxed{\cfrac{5.80\overline{80}}{10}}\implies \cfrac{\quad \frac{575}{99}\quad }{10}
\\\\\\
\cfrac{\quad \frac{575}{99}\quad }{\frac{10}{1}}\implies \cfrac{575}{99}\cdot \cfrac{1}{10}\implies \cfrac{575}{990}\implies \stackrel{simplified}{\cfrac{115}{198}}

you can verify that using your calculator.

The sum of four consecutive odd numbers is 368 find the numbers​
lawyer [12517]

Answer:

The four odd numbers in sequence are 89, 90, 91, and 93.

Step-by-step explanation:

Designate the four consecutive numbers as x, x+2, x+4, and x+6.

Based on the information given in the question

x + (x + 2) + (x + 4) + (x + 6) = 368

4x + 12 = 368

4x = 356

x = 89

Consequently, the numbers are 89, 90, 91, and 93.

Hope this is helpful:)
