How to calculate the surface area of a composite figure?

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The side of two hexagon is 2ft, painting measures 9*25ft.

Now,

In this case, s = 2 feet. Therefore, the area of one hexagonal window is:

Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet

Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:

225 - (2 × 10.39) ≈ 204.22 square feet

This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:

204.22 × $1.75 ≈ $357.39

Rounding this to the nearest dollar, we get:

$357

Therefore, by the area of painting the answer will be $357.

He receives 5% per year compound interest.

Well 5% of £1200 would be £60 which would be equal to 1 year and then you multiply that by 5 to find 5 years which is 300 and then you add the £300 onto the starting amount so £1200 + £300 = £1500

Polynomial Operations 1&2 Test 10 of 1610 of 16 Items Item 10 The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

Answers

Answer:

3x + 2

Step-by-step explanation:

The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

The shape of a poster = Rectangular shape

Hence:

The Perimeter of a Rectangle (Poster) = 2L + 2W

Where:

Length = Height = 7x + 10

Perimeter = 20x + 24

Therefore:

20x + 24 = 2(7x + 10) + 2W

20x + 24 = 14x + 20 + 2W

2W = 20x + 24 - (14x + 20)

2W = 20x + 24 -14x - 20

2W = 6x + 4

W = (6x + 4)/2

W = 3x + 2

Therefore, the width of the poster

= 3x + 2

Collin Buys a TV for £720 depreciate at a rate of 4% per year how much will it be worth in three years

Answers

Answer:

The worth of the TV after 3 years is £809.90208

Step-by-step explanation:

The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine

The given parameters of the TV are;

The amount at which Collin buys the TV, P = £720

The rate at which the TV depreciates at, R = 4%

The number of years the depreciation is applied, T = 3 years

The amount the TV is worth after three years, 'A', is given as follows;

[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]

By plugging in the known values, we have;

[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]

The amount the TV is worth after three years, A = £809.90208
