What’s the absolute value for this ?

Answer:

The answer is D.

Step-by-step explanation:

The domain are the x-values and the range are the y-values. The open circle on the graph is stating that that specific point is not included in the line, so that means that the point (-2,-5) is not included. In words, the answer means the domain or x=all real numbers not including -2 and the range or y=all real numbers not including -5. Hope it helps

Answer:

36

Step-by-step explanation:

Quadrilateral's angels always add up to 360. Thus, 2x+5x+6x+7x=360

20x=360 (divide both sides by 20)

x = 18

To find the smallest angle, plugin x into 2x.

2(18)=36

Answer:

b) 9 in

Step-by-step explanation:

To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.

If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median

Ascending order:

6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16

total = 10. so even number

Median = average of 5th term and 6th term

             =(9+9)/2

             = 18/2

              = 9

Answer:

A : D

4 : 3

Step-by-step explanation:

We'll use the first letter of their names as the heading for the ratio.

The first line states:

A : B

2 : 1

The second line states:

B : C

1/3 : 1

The third line states:

C : D

2 : 1

We have three different ratios but we know that they are related to one another so we are going to combine them by equating the common ratio of the different ratios.

Let's look at the ratio with a fraction first.

B : C

1/3 : 1

If we ×3 throughout, this can also be written as:

B : C

1 : 3

Now B in the first and second ratio is the same number and we are able to combine them. We can write them all together like this:

A : B : C

2 : 1 : 3

In the third ratio, C is 2, however in the ratio we have now C is 3. We can make them the same number by ×3 throughout the third ratio and ×2 throughout the ratio we have now.

C : D

2 : 1

6 : 3

A : B : C

2 : 1 : 3

4 : 2 : 6

We can see that our ratio for C is the same number and we can now combine the ratios.

A : B : C : D

4 : 2 : 6 : 3

The question asked for A : D so we can take just the values of A and D.

A : D

4 : 3

Answer:

see explanation

Step-by-step explanation:

Given that z² is directly proportional to w then the equation relating them is

z² = kw ← k is the constant of proportion

To find k use the condition z = 4 when w = 8, thus

4² = 8k

16 = 8k ( divide both sides by 8 )

2 = k

(i)

z² = 2w ← equation of proportion

(ii)

When w = 18, then

z² = 2 × 18 = 36 ( take the square root of both sides )

z = [tex]\sqrt{36}[/tex] = 6

(iii)

When z = 5 , then

5² = 2w

25 = 2w ( divide both sides by 2 )

w = 12.5

Answer:

subtract 2, and add 5 repeatedly

Step-by-step explanation:

49, 47, 52, 50, 55

subtract 2, and add 5 repeatedly

49-2=47

47+5=52

52-2=50

50+5=55

55-2=53

53+5=58

and so on........

The pattern between these numbers is first subtracting 2 and then adding 5.

To find a pattern between a given sequence of numbers observe the sequence carefully and try to think about different arithmetic operations that can be suited for.

According to the given question we have to find pattern between these numbers 49, 47, 52, 50, 55.

After observing this sequence of numbers we can understand than they are in the sequence pattern of subtracting 2 and adding 5.

Now,

49 - 2 = 47.

47 + 5 = 52.

52 - 2 = 50.

50 + 5 = 55.

Answer:

m = 6

Step-by-step explanation:

We know that m and n vary directly and that m = 3 when n = 2. How would we find m when n = 4? For starters, we can see that the value of n doubled (we know this because 2 doubled is 4), and since m and n vary directly, when n doubles, so does m so the answer is m = 3 * 2 = 6.

Answer:

8 in.

Step-by-step explanation:

Perimeter of a rectangle, P = 2(L + W)

Value of P = 46.

Length is 7 inches less than the width.  This translates to L = W - 7

Substitute L = W - 7 into the perimeter equation, you get

46 = 2(W - 7 + W)

46 = 2(2W - 7)

46 = 4W - 14

4W = 60

W = 60 / 4 = 15 in

L = W - 7 = 15 - 7 = 8 in

The width and length of the rectangle in inches are 17 and 10 respectively.

Perimeter is the sum of the lengths of all the sides of a given plane figure.

According to the given question the length of a rectangle is 7 inches less than its width.

Assuming the width of the rectangle is x inches.

∴ From the given data length of the rectangle is ( x - 7) inches.

Given perimeter is 54 inches.

We know perimeter of a rectangle is 2( length + breadth).

∴ 2{ x + ( x - 7) } = 54.

  2 { 2x - 7 } = 54

  4x - 14 = 54

  4x = 54 + 14

  4x = 68

    x = 17.

So, the width of the rectangle is 17 inches and length of the rectangle is (17 - 7) inches which is 10 inches.

Answer:

The lines' lengths are: 8 inches and 5 inches.

Step-by-step explanation:

Calling "a" the length of the line, a line that is 3 inches shorter can be written in math terms as:

a - 3

If the combined (added) length of these two lines is 15 inches, then we can write:

a + (a - 3) = 15

a + a - 3 = 15

2 a - 3 = 15

2 a = 15 + 3

2 a = 18

then

a = 18/2 = 9

Therefore, the length of one line is 8 inches, and the length of the shorter line is:

8 - 3 = 5 inches

The correct answer is D. 6

Explanation:

To know precisely how the number of restaurants in the city decreases over time, it is necessary to determine the 18% of the total of restaurants each year and to subtract this number. The process year per year is shown below:

First-year- 60 restaurants- Find the percentage by writing the known value and using cross multiplication

[tex]60 = 100[/tex] %

[tex]x = 18[/tex]%

[tex]x 100 = 60 x 18[/tex]

[tex]x = \frac{1080}{100}[/tex]

[tex]x = 10.8[/tex]   Number of restaurants that were closed

[tex]60-10.8 = 49.2[/tex] New total

Second-year - 49.2 restaurants- Repeat te process

[tex]x = \frac{49.2x 18}{100}[/tex] Shortened version of the equation. Total of restaurants, multiplied by percentage and divided into 100 (total percentage)

[tex]x = 8.8[/tex]

[tex]49.2 - 8.8 = 40.4[/tex] New total

Third-year- 40.4 restaurants

[tex]x = \frac{40.4 x 18}{100}[/tex]

[tex]x = 7.2[/tex]

[tex]40.4-7.2 = 33.2[/tex]  New total

Fourth-year- 33.2 restaurants

[tex]x = \frac{33.2x 18}{100}[/tex]

[tex]x = 6.3[/tex]

[tex]33.2- 6.3= 26.9[/tex] New total

Fifth-year- 26.9 restaurants

[tex]x = \frac{26.9 x 18}{100}[/tex]

[tex]x = 4.8[/tex]

[tex]26.9-4.8 = 22.1[/tex] New total

Sixth-year- 22.1 restaurants

[tex]x = \frac{22.1x 18}{100}[/tex]

[tex]x= 3.96[/tex]

[tex]22.1-3.9 = 18.1[/tex]

According to this at this rate, it will take at least 6 years for the number of restaurants to be below 20.

Answer:

=30076 customers

Step-by-step explanation:

Number of customer= 51,200

rate of declination=3.8 %= 0.038

We will use the expresion below in calculating the approximate number of customers that visit the business in 14 years.

A=Pe^(rt)

Where P=initial amt,

r=annual rate of growth or decline,

A=amount after t years.

37800=Pe^.017t

51200=Pe^0.038

P= 51200/e^(0.038*14)

But e^(0.038*14)= 1.7023

P= 51200/1.7023

P=30076

Approximate number of customers that visit the business in 14 years≈30076
