so i need help with question number 7. explain plz

Hi there!

h(x) = 5x + 11

To find h(7) - 3, we can substitute 7 for x and subtract 3:

h(7) = 5(7) + 11 - 3

Simplify:

h(7) = 35 + 11 - 3

h(7) = 43

h(x) = 5x + 11

h(7) = 5 · 7 + 11 = 35 + 11 = 46

h(7) - 3 = 46 - 3 = 43 ← the end answer

it is less than square root 30

Answer:

The answer to the proportion is 8

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.

Answer:

77 cm²

Step-by-step explanation:

We know that

Area of trapezium = ½ (a + b) × h

Area = ½ × (10 + 12) × 7

Area = ½ × 22 × 7

Area = 11 × 7

Area = 77 cm²

Length of parallel sides = 10 cm and 12 cm

Height = 7 cm

Area of trapezium

[tex]\begin{gathered} {\underline{\boxed{ \rm {\red{Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: (a \: + \: b) \: \times \:Height }}}}}\end{gathered}[/tex]

Answer:

Step-by-step explanation:

2/5 = 16/x

2x = 80

x = 40

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:

angle C = 78

angle D = 108

Step-by-step explanation:

the measure of angle A is 102

To find the measure of angle C

let Angle C be x

102 + x = 180 (linear pair)

x = 180 -102

x = 78

angle C = 78

angle B = 78 (vertically opposite angles are equal)

angle D = 108 (vertically opposite angles are equal)

Answer:

g=5

Step-by-step explanation:

6.3g + 8 = 2.3g + 28

Subtract 2.3g from each side

6.3g-2.3g + 8 = 2.3g-2.3g + 28

4g +8 = 28

Subtract 8 from each side

4g+8-8= 28-8

4g = 20

Divide by 4

4g/4 = 20/4

g = 5

Answer:

g = 5

Step-by-step explanation:

6.3g + 8 = 2.3g + 28

Subtract 2.3g from each side

6.3g-2.3g + 8 = 2.3g-2.3g + 28

4g +8 = 28

Subtract 8 from each side

4g+8-8= 28-8

4g = 20

Divide by 4
