A plank measures 4 and 3/4 feet. Elizabeth cuts off 2/5 of the plank. How long is the plank now?

Answer:

[tex]\boxed{Quadrant4}[/tex]

The answer should be found in quadrant four it is.

Step-by-step explanation:

x-axis- is a horizontal axis.

y-axis- is a vertical axis.

x-coordinate- is a horizontal position.

y-coordinate- is a vertical position.

quadrant- is a quarter of the coordinate plane.

origin- is a point of intersection of the two axes.

First you had to find quadrant of (7,-12).

Go to the right at it said seven and then go down to the negative twelve and its should be found in quadrant four.

(7,-12) it should be found in quadrant four.

(-7,-12) it should be found in quadrant three.

(-7, 12) it should be found in quadrant two.

(7, 12) it should be found in quadrant one.

Hope this helps!

The required integers are -8 and -6, or 6 and 8 whose the product of two consecutive even integers is 48

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.

Let the two consecutive even integers be 2n and 2(n+1), where n = any integer.

As per the given condition, The product of the two integers is 48

2n × 2(n+1) = 48            

Multiply out, and subtract 48 from both sides

4n2+4n-48=0                            

Divide both sides by 4

n²+n-12=0                            

Factor the quadratic

(n+4)(n-3)=0                      

n= -4 and +3

For n= -4, 2n = -8 and 2(n+1) = -6.  (-8)(-6) = 48

For n=3, 2n = 6 and 2(n+1) = 8.  (8)(6) = 48

Thus, the required integers are -8 and -6, or 6 and 8.

( subtract what she already has from 1300)

In the 2008 election, the fractions of 'blue' and 'red' states when expressed in lowest terms were 14/25 and 11/25 respectively. In decimal form, these values are 0.56 and 0.44.

When solving fractions in mathematics, there are straightforward steps to follow. In the context of the 2008 election with the “red” and “blue” states, this means calculating the fraction of each in relation to the total number of states which is 50 in the US. The total number of red states was 22 and the total number of blue states was 28.

To express this as fractions we utilize the simple fraction formula of Part/Whole. For the blue states, the fraction becomes 28/50. To bring this to its lowest terms divide both the numerator and the denominator by their greatest common divisor which in this case is 2, so the fraction becomes 14/25.

Similarly, for the red states, we use the fraction formula where the red states are the part (22) and the whole is all the states (50). This gives a fraction of 22/50 which simplifies to 11/25 when reduced to lowest terms.

When these fractions are expressed as decimals, 14/25 equals to 0.56 while 11/25 equals to 0.44.

Answer: 49, 64, and 81

Step-by-step explanation: To find the next three terms in this pattern, begin by studying the pattern.

Notice that the difference between 1 and 4 is positive 3, the difference between 4 and 9 is positive 5, the difference between 9 and 16 is positive 7, the difference between 16 and 25 is positive 9, and the difference between 25 and 36 is positive 11.

Since the differences are increasing by 2 each time, we can find the next term in the pattern by adding 36 + 13 to get 49. Next, we will add 49 + 15 to get 64. Then, we will add 64 + 17 to get 81.

Thus, the next three terms in the pattern are 49, 64, and 81.

Answer:

4 Of them

Step-by-step explanation:

So an easy way to do this is by adding 2/3 for a while till we hit max. Like this:

2/3+2/3=1 1/3+2/3= 2+2/3=2 2/3+ 2/3= 3 1/3+2/3= 4. so 6 of them

Hope this helps!

Final answer:

To find out how many 2/3-cup servings are in four cups of pistachios, you divide 4 cups by 2/3 cup, which equals 6 servings.

Explanation:

To determine how many 2/3-cup servings are in four cups of pistachios, you would divide the total number of cups by the size of one serving:

Total servings = Total volume \/ Size of one serving = 4 cups / (2/3 cup)

To divide by a fraction, multiply by its reciprocal:

Total servings = 4 / (2/3) = 4 * (3/2) = 4 * 1.5 = 6

So, there are six 2/3-cup servings in four cups of pistachios.

Nora should choose Option 1 because it will take her 4 nights to finish instead of 25 nights with Option 2.

Let's break down Nora's situation step by step:

1. Calculate the total number of pages in the book:

  Since Nora has already read thirty percent of the book, we can find the total number of pages by dividing the portion she read by 30% (or 0.30). Let's denote the total number of pages as ( P ).

[tex]\[ P = \frac{{\text{portion Nora read}}}{{\text{percentage read}}} = \frac{{\text{portion Nora read}}}{{0.30}} \][/tex]

2. Calculate the portion of the book Nora has already read:

  If Nora has already read thirty percent of the book, then she has already read [tex]\( 0.30 \times P \)[/tex] pages.

3. Calculate the number of pages Nora has remaining:

  Subtract the pages Nora has already read from the total number of pages in the book.

[tex]\[ \text{Pages remaining} = P - (0.30 \times P) = P(1 - 0.30) = 0.70P \][/tex]

4. Option 1: Read 25% of the remaining pages each night:

  Nora's plan is to read 25% of the remaining pages each night. Since she has (0.70P) pages remaining, she will read [tex]\( 0.25 \times 0.70P \)[/tex] pages each night.

5. Option 2: Read 28 pages each night:

  Nora's other option is to read 28 pages each night.

6. Compare the two options:

  To determine which option Nora should choose, we compare the number of nights it will take her to finish each option.

  - With Option 1, the number of nights Nora will need to finish the book is [tex]\( \frac{{0.70P}}{{0.25 \times 0.70P}} \).[/tex]

  - With Option 2, the number of nights Nora will need to finish the book is [tex]\( \frac{{0.70P}}{{28}} \).[/tex]

7. Choose the more efficient option:

  Nora should choose the option that requires fewer nights to finish the book.

Let's summarize the steps:

1. Calculate the total number of pages in the book.

2. Determine the portion of the book Nora has already read.

3. Calculate the number of pages Nora has remaining.

4. Calculate the number of pages Nora will read each night for Option 1.

5. Compare the number of nights needed for each option.

6. Choose the option that requires fewer nights to finish the book.

This process will help Nora decide which option is more efficient for her to finish reading the book.

Let's denote:

- Total number of pages in the book as ( P ).

- Number of pages Nora has already read as ( 0.30P ).

- Number of pages Nora has remaining as ( 0.70P ).

With Option 1, Nora will read [tex]\( 0.25 \times 0.70P = 0.175P \)[/tex] pages each night.

To find the number of nights needed to finish with Option 1:

[tex]\[ \text{Number of nights with Option 1} = \frac{{0.70P}}{{0.175P}} = 4 \][/tex]

With Option 2, Nora will read 28 pages each night.

To find the number of nights needed to finish with Option 2:

[tex]\[ \text{Number of nights with Option 2} = \frac{{0.70P}}{{28}} = 25 \][/tex]

Nora should choose Option 1 because it will take her 4 nights to finish instead of 25 nights with Option 2.
