if a box of tiles costs R85. 00 calculate the cost of tiles per square metre

Answers

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:

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)

4. 10and 40 [5]
5. 1⁄2 and 2 [2]

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

How to solve arithmetic sequence?

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

4. Tabatha is dining out at Mandee's and decides to get an order of curly fries.
chicken fingers, and a coca-cola. The total cost of the food with sales tax came to
$18.61. If Tabatha decides to give the cashier a 20% gratuity (tip), what does ber
total bill come to?

Answers

Answer:

$22.33

Step-by-step explanation:

A 20% tip would be 0.20. Multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total amount including tip.

subtotal --> $18.61

tip --> $3.72

18.61 x 0.20 = 3.72

total --> $22.33

the length of a new rectangular playing field is 9 yards longer than double the width. if the perimeter of the rectangular playing field is 288 yards, what are it's dimensions?

Answers

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

Find h(7) - 3 if h(x) = 5x + 11

Answers

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

Answers

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

4g/4 = 20/4

g = 5
