Beth simplified the expression 8 + 10 + 8 + 2 minus (4 times 1.4) minus (4 times 1.4) to find the perimeter of the figure on the grid.

On a coordinate plane, a figure has side lengths of 8, 10, 8, 2, (4 times 1.4), (4 times 1.4).

What error did Beth make?
She found the area of the figure instead of the perimeter.
She subtracted the lengths of the diagonal lines instead of adding them.
She used 4 times 1.4 to represent the length of each diagonal line instead of 4.
She added the horizontal and vertical lengths instead of multiplying them.

Answers

Answer 1

Answer:

Step-by-step explanation:

the answer is 16.8

Explanation: well for starters you have to do what's in the parenthesis, so 4 times 1.4 is equal to 5.6. so now we add up the equation and get 28, so now we are left with 28-5.6-5.6 which equals 16.8

hoped this helped;)

Assume this is a partial list of financial highlights from a Best Buy annual report (dollars in millions):
Net sales
2020 - $40,580
2019 - $35,475

Earnings before taxes
2020 - $2,291
2019 - $1,313

Net earnings
2020 - $1,378
2019 - $921

Find horizontal analysis and vertical analysis.

Answers

You subtract $1313 from $2,291

Value of Horizontal Analysis:

⇒ Net sales = 14.4%

⇒ Earnings before taxes = 74.4%

⇒ Net earnings = 49.6%

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

⇒ Net earnings = 3.4%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, We can find as;

Horizontal Analysis:

Here, Calculate the dollar change by subtracting the previous year's figure from the current year's figure for each item:

Net sales = $40,580 million - $35,475 million

              = $5,105 million increase

Earnings before taxes = $2,291 million - $1,313 million

                                  = $978 million increase

Net earnings = $1,378 million - $921 million

                    = $457 million increase

Hence, Calculate the percentage change by dividing the dollar change by the previous year's figure and multiplying by 100 as;

Net sales = ($5,105 million / $35,475 million) x 100

               = 14.4% increase

Earnings before taxes = ($978 million / $1,313 million) x 100

                                  = 74.4% increase

Net earnings = ($457 million / $921 million) x 100

                   = 49.6% increase

And, Vertical Analysis:

Calculate the percentage of each item in relation to the net sales by dividing each item by the net sales and multiplying by 100:

Net sales = $40,580 million / $40,580 million x 100

               = 100%

Earnings before taxes = $2,291 million / $40,580 million x 100

                                  = 5.6%

Net earnings = $1,378 million / $40,580 million x 100

                    = 3.4%

Thus, Value of Horizontal Analysis:

⇒ Net sales = 14.4%

⇒ Earnings before taxes = 74.4%

⇒ Net earnings = 49.6%

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

⇒ Net earnings = 3.4%

By doing cross multiply, you'll get

Expand

6p-6 = 8p+80

Arrange

-80-6 = 8p-6p

-86 = 2p

Divide by 2 to find p

-43 = p

Answer:

p =

Step-by-step explanation:

First, we can start by cross multiplying.

p−1p+10=86

(p−1)*(6)=8*(p+10)

6p−6=8p+80

After some simplification, we get:

−2p=86

Then we find out that p = -43

If we put it in, and then simplify that, we will get 8/6
