Answer:

Step-by-step explanation:

Width = w

Length =2w + 9

Perimeter = 288 yards

2*(length + width) = 288

2*(2w + 9 + w) = 288

2*(2w + w +9) = 288 {Combine like terms}

2*(3w + 9 )     = 288

2*3w + 2*9    = 288             {Use distributive property}

6w + 18          = 288             {Subtract 18 from both sides]

                 6w = 288 - 18

                 6w = 270       {Divide both sides by 6}

                   w = 270/6

w = 45 yards

Length = 2*45 + 9 = 90 +9 = 99 yards

Length = 99 yards

Width = 45 yards

The complete Arithmetic Sequence for each of the sequences are;

1) 2, 17, 32

2) 6, 18, 30, 42, 54

3) 68, 55, 42, 29, 16, 3

4) 10, 15, 20, 25, 30, 35, 40

5) ½, 1, 3/2, 2

1. Using the formula for the nth term of an arithmetic sequence:

a_n = a₁ + (n - 1)d , find d.

     a₁ = 2         n = 3

a_n = a₁ + (n – 1)d

32 = 2 + (3 – 1)d

32 = 2 + (2)d

32 = 2 + 2d

32 – 2 = 2d

30 = 2d

30/2 = 2d/2

15 = d

Using d = 15, find a₂.

a₂ = a₁ + (2 – 1)15

a₂ = 2 + (1)15

a₂ = 2 + 15

a₂ = 17

2. Using the formula for the nth term of an arithmetic sequence:

a_n = a₁ + (n - 1)d , find d.

  a₁ = 6       n = 5       a_n = 54

a_n = a₁ + (n – 1)d

54 = 6 + (5 - 1)d

54 = 6 + (4)d

54 = 6 + 4d

54 - 6 = 4d

48 = 4d

48/4 = 4d/4

12 = d

Using d = 12, find a₂, a₃, and a₄.

a₂ = a₁ + (n - 1)d              a₃ = a₁ + (n - 1)d           a₄ = a₁ + (n - 1)d

a₂ = 6 + (2 - 1)12             a₃ = 6 + (3 - 1)12          a₄ = 6 + (4 - 1)12

a₂ = 6 + (1)12                  a₃ = 6 + (2)12              a₄ = 6 + (3)12

a₂ = 6 + 12                     a₃ = 6 + 24                 a₄ = 6 + 36

a₂ = 18                          a₃ = 30                       a₄ = 42

3. Using the formula for the nth term of an arithmetic sequence:

a_n = a₁ + (n - 1)d , find d.

a₁ = 68       n = 6       a_n = 3

a_n = a₁ + (n – 1)d

3 = 68 + (6 - 1)d

3 = 68 + (5)d

3 = 68 + 5d

3 - 68 = 5d

-65 = 5d

-65/5 = 5d/5

-13 = d

Using d = -13, find a₂, a₃, a₄ and a₅.

a₂ = a₁ + (n - 1)d              a₃ = a₁ + (n - 1)d           a₄ = a₁ + (n - 1)d

a₂ = 68 + (2 - 1)-13          a₃ = 68 + (3 - 1)-13       a₄ = 68 + (4 - 1)-13

a₂ = 68 + (1)-13               a₃ = 68 + (2)-13           a₄ = 68 + (3)-13

a₂ = 68 - 13                    a₃ = 68 - 26               a₄ = 68 - 39

a₂ = 55                          a₃ = 42                      a₄ = 29

a₅ = a₁ + (n - 1)d              

a₅ = 68 + (5 - 1)-13        

a₅ = 68 + (4)-13              

a₅ = 68 - 52                    

a₅ = 16

4. Using the formula for the nth term of an arithmetic sequence:

a_n = a₁ + (n - 1)d , find d.

a₁ = 10       n = 7       a_n = 40

a_n = a₁ + (n – 1)d

40 = 10+ (7 - 1)d

40 = 10 + (6)d

40 = 10 + 6d

40 - 10 = 6d

30 = 6d

30/6 = 6d/6

5 = d        

Using d = 6, find a₂, a₃, a₄ a₅ and a₆.

a₂ = a₁ + (n - 1)d              a₃ = a₁ + (n - 1)d           a₄ = a₁ + (n - 1)d

a₂ = 10 + (2 - 1)5             a₃ = 10 + (3 - 1)5          a₄ = 10 + (4 - 1)5

a₂ = 10 + (1)5                  a₃ = 10 + (2)5              a₄ = 10 + (3)5

a₂ = 10 + 5                     a₃ = 10 + 10                a₄ = 10 + 15

a₂ = 15                          a₃ = 20                      a₄ = 25

a₅ = a₁ + (n - 1)d              a₆ = a₁ + (n - 1)d          

a₅ = 10 + (5 - 1)5             a₆ = 10 + (6 - 1)5        

a₅ = 10 + (4)5                  a₆ = 10 + (5)5          

a₅ = 10 + 20                    a₆ = 10 + 25                

a₅ = 30                          a₆ = 35

5. Using the formula for the nth term of an arithmetic sequence:

a_n = a₁ + (n - 1)d , find d.

a₁ = 1/2       n = 4       a_n = 2

a_n = a₁ + (n – 1)d

2 = 1/2+ (4 - 1)d

2 = 1/2 + (3)d

2 = 1/2 + 3d

2 - 1/2 = 3d

3/2 = 3d

3/2/3 = 3d/3

1/2 = d              

Using d = 1/2, find a₂, and a₃.

a₂ = a₁ + (n - 1)d              a₃ = a₁ + (n - 1)d          

a₂ = 1/2 + (2 - 1)1/2         a₃ = 1/2 + (3 - 1)1/2          

a₂ = 1/2 + (1)1/2              a₃ = 1/2 + (2)1/2            

a₂ = 1/2 + 1/2                 a₃ = 1/2 + 1              

a₂ = 1                            a₃ = 3/2

Answer:

4,24,48

Step-by-step explanation:

For the first equation, they are splitting 8 in half. So 8/2 would be 4. The 4 would go in the first box.

Then 4x6 is 24 in the second box.

Then just add 24 and 24. 24+24=48

And your last answer is 48.

There are a total of 44 candies in the box.

The total ratio is 24

Let;

11/22 * x = y  ----  (1)

If the candies were shared equally

The ratio of candies in R will be 6

6/24 * x = y - 11 --- (2)

substitute  y = 11/22 * x  in (2)

6x/24 = 11x/22 - 11

x/4 = x/2  - 11

multiply through with 4

x = 2x - 44

x = 44

Therefore, there are a total of 44 candies.

∠1 and ∠2 are supplementary angles. m∠1 is 4y+7, and m∠2 is 9y+4. Find m∠2.

The sum of supplementary angle is 180°

First, solve for the value of y.

Then, plug and substitute the value y = 13 to find the m∠2.

The measure of angle 2 is 121 degrees.

Given:

[tex]m\angle1=4y+7\\m\angle2=9y+4[/tex]

Recall: Supplementary angles are angles whose sum equals [tex]180^{o}[/tex]

To solve this problem, create an equation to find the value of x:

Thus:

[tex]m\angle1 +m\angle2=180[/tex]

Therefore:

[tex](4y+7)+(9y+4) = 180\\[/tex]

Solve for y:

[tex]4y+7+9y+4 = 180\\\\[/tex]

Add like terms:

[tex]13y+11 = 180\\\\[/tex]

Subtract 11 from both sides

[tex]13y+11 - 11= 180 - 11\\13y = 169[/tex]

Divide both sides by 13

[tex]\frac{13y}{13} = \frac{169}{13} \\y = 13[/tex]

Find the m∠2 by substituting [tex]y = 13[/tex] into [tex]9y +4[/tex]

[tex]m\angle= 9(13)+4\\m\angle = 121^{o}[/tex]

Therefore, m∠2 = 121 degrees.

Answer:

P = 100

Area = 625

Step-by-step explanation:

Area = s^2

sqrt(area) =  sqrt(s^2)

area = 25*25

sqrt(25*25) = sqrt(s^2)

s = 25

P = 4*s

P = 4 * 25

P = 100

Area = s^2

s = 25

Area = 25^2

Area = 625

The cost of tiles per square meter is an illustration of unit rates. If the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.

Given that:

[tex]Cost = R85.00[/tex]

The unit cost (i.e. cost of tiles per square metre) is calculated as:

[tex]Unit =\frac{Cost}{Area}[/tex]

Where:

[tex]Cost = R85.00[/tex]

[tex]Area \to[/tex] Area of the tiles

The dimension of a tile is not given. So, I will use an assumed value.

Assume the tile has an area of 17m^2.

So, the unit cost is:

[tex]Unit = \frac{85.00}{17}[/tex]

[tex]Unit = 5[/tex]

Hence, if the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.
