How can I find the area of this irregular shape?

Answer:

\( \frac{12}{7} \)

Step-by-step explanation:

Side length of red ∆ = 12

Side length of blue ∆ = 7

Given that the red ∆ is similar to the blue ∆, therefore the ratio of their corresponding sides = the ratio of their perimeter.

The ratio of the perimeter of red ∆ to perimeter of blue ∆ = side length of red ∆ / side length of blue ∆

\( = \frac{12}{7} \)

The ratio (red to blue) of the perimeters of the similar triangles is 12:7

Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.

Perimeter of a triangle = s1 + s2 + s3

For the red triangle;

Perimeter of the red triangle = 12 + 12 + 12

Perimeter of the red triangle = 36

For the blue triangle:

Perimeter of the blue triangle = 7 + 7 + 7

Perimeter of the blue triangle = 21

Taking the ratio of their perimeters;

Ratio of red to blue = 36:21 = 12:7

Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

For the quadratic equation 2x² - 4x - 48 = 0 value of x is 6 and -4.

What is quadratic equation?

The second-degree equation is a quadratic equation. This indicates that it has at least one (1) squared phrase. Ax2 + bx + c = 0 is one of the most used formulas for solving quadratic equations. Here, a, b, and c are constants or numerical coefficients. Here, the variable "X" is unknowable.

ax^2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

We have a quadratic equation;

2x² - 4x - 48 = 0

To find the value of x we have to follow these steps ;

(2x^2 -  4x) -  48  = 0

Pull out like factors :

2x^2 - 4x - 48  =   2 • (x^2 - 2x - 24)

x2 multiplied by 2x and 24

x^2 is the initial term, and it has a coefficient of 1.

The coefficient of the middle term, which is -2x, is 2.

"The constant," the final term, is -24.

⇒ x^2 - 6x + 4x - 24

⇒   (x+4)  •  (x-6)

⇒ 2 • (x + 4) • (x - 6)  = 0

therefore x+4 = 0

 x = -4

and   x-6 = 0

Add  6  to both sides of the equation :

                     x = 6

Hence, for the quadratic equation 2x² - 4x - 48 = 0 value of x is 6 and -4.

The correct answer is $56,000.the total profit for Pinewood Furniture Company, considering only the production of 200 chairs and 400 tables

To determine the total profit for Pinewood Furniture Company, we need to calculate the profit generated from producing 200 chairs and 400 tables.

Each chair generates a profit of $80, and if 200 chairs are produced, the total profit from chairs would be:

200 chairs * $80/profit per chair = $16,000.

Similarly, each table generates a profit of $100, and if 400 tables are produced, the total profit from tables would be:

400 tables * $100/profit per table = $40,000.

Therefore, the total profit for Pinewood Furniture Company, considering only the production of 200 chairs and 400 tables, would be:

$16,000 (profit from chairs) + $40,000 (profit from tables) = $56,000.

Hence, the correct answer is $56,000.

Answer:

height=24cm

Step-by-step explanation:

CSA of cone=550cm square

slant height=25cm

Height of the cone=?

Now,

CSA=pie rl (formula)

or, 550=22÷7×r×25

or,550×7=22×r×25

or,r=7cm

Answer:

Step-by-step explanation:

8 sqaure feet

The object is cone and a cylinder combined,

So first we get the areas of both and sum the both.

TSA of a cylinder =2 πr+(r + h)

=2 π x (5)+(5+7)=43.41592654

Then the TSA of a cone

= πr(l + r)

π x5(11+5)=80 π

REMEMBER THEY HAVE THE SAME RADIUS SINCE THEY ARE JOINED!!

Therefore,

80 π + 43.41592654= 295cm squared to whole number

Answer:

200π cm².

Step-by-step explanation:

To find the total surface area of the solid made from a cone and a cylinder, we need to calculate the surface area of each component separately and then add them together.

1. Surface area of the cone:

The surface area of a cone can be calculated using the formula: πr(r + l), where r is the radius of the base and l is the slant height.

Given that the radius of the cone is 5 cm and the slant height is 11 cm, we can substitute these values into the formula to find the surface area of the cone.

Surface area of the cone = π(5)(5 + 11) = 80π cm²

2. Surface area of the cylinder:

The surface area of a cylinder can be calculated using the formula: 2πrh + 2πr², where r is the radius of the base and h is the height.

Given that the radius of the cylinder is also 5 cm and the height is 7 cm, we can substitute these values into the formula to find the surface area of the cylinder.

Surface area of the cylinder = 2π(5)(7) + 2π(5)² = 70π + 50π = 120π cm²

3. Total surface area:

To find the total surface area of the solid, we add the surface area of the cone to the surface area of the cylinder.

Total surface area = Surface area of the cone + Surface area of the cylinder

Total surface area = 80π + 120π

Total surface area = 200π cm²

Therefore, the total surface area of the solid, including the base, in terms of pi is 200π cm².

5). Triangle DEF is an equilateral triangle.

Therefore, measure of all sides and the angles of the triangle will be equal.

DE = EF = DF = 5.2 ft

3y + 1 = 5.2

3y = 5.2 - 1

3y = 4.2

y = 1.4

Similarly, m∠D = 60° [Measure of all angles of an isosceles triangle = 60°]

(5x)° = 60°

x = \(\frac{60}{5}\)

x = 12

6). Property to be used in ΔFGH,

"Two sides of an isosceles triangle are equal in measure and opposite angles of the equal sides of the triangle are equal"

FG = GH

The non-constructivity here is that, unless you know some deeper number theory than just irrationality of 2–√2, you won't know which of the two cases in the proof actually occurs, so you won't be able to give aa explicitly, say by writing a decimal approximation.
