The given statement "An equiangular triangle can never be scalene." is true.

An equiangular triangle is a triangle that has three equal angles.

A scalene triangle is a triangle that has three unequal sides.

Therefore, a scalene triangle has three different angles.

Therefore, an equiangular triangle and scalene triangle are two completely different triangles.

Hence, an equiangular triangle can never be a scalene triangle.

Definition of Square: a parallelogram whose area is equal to the product of its sides. The circle is a plane figure whose area is calculated by the formula r².

The length of the side of the square is .

Given:

The radius of the circle is = r cm.

Length of the side of square = a cm

Now,

Area of Square is = a²

Area of Circle  = r²

Since, given that radius of a circle is equivalent to the length of the square, such that:

a² =  r²

a² =   r²

a =

a =

Thus, the value of the length of the square is r√π.

Step-by-step explanation:

Answer:  The area of the shaded portion is [tex](\pi-2)~\textup{sq. units}.[/tex]

Correct option is 2.

Step-by-step explanation:  We are given to find the area of the shaded portion in the figure.

Since, the centre point of each arc is the corresponding central point of the line and the arcs intersect at the centre point of the circle,

so let us divide the figure into four equal parts, one of them is square ABCD as shown in the attached figure.

The area of the square ABCD will be

[tex]A_{ABCD}=\left(\dfrac{1}{2}\times 2\right)^2\\\\\\\Rightarrow A_{ABCD}=1~\textup{sq. units}.[/tex]

Now, area of the shaded portion inside the square ABCD will be

[tex]A_s=2\times \textup{area of the quarter circle with radius 1 unit}}-\textup{area of square ABCD}\\\\\Rightarrow A_s=2\times \left(\pi\times \left(\dfrac{1}{2}\right)^2\right)-A_{ABCD}\\\\\\\Rightarrow A_s=2\times\left(\dfrac{\pi}{4}\right)-1\\\\\\\Rightarrow A_s=\left(\dfrac{\pi}{2}-1\right)~\textup{sq. units}.[/tex]

Since all the four squares are identical in the attached figure, so the required area of the total shaded portion in the figure is

[tex]A=2\times\left(\dfrac{\pi}{2}\right)\\\\\\\Rightarrow A=(\pi-2)~\textup{sq. units}.[/tex]

Thus, the area of the shaded portion is [tex](\pi-2)~\textup{sq. units}.[/tex]

The correct option is 2.

The product of -9(5-2x) is found by multiplying -9 by each term inside the parentheses resulting in -45 + 18x.

The product of -9(5-2x) is found by distributing the -9 to both terms inside the parentheses. Following the rules of multiplication, when a negative number multiplies a positive number, the result is negative, and when a negative number multiplies a negative number, the result is positive. Hence:

-9 x 5 = -45

and

-9 x -2x = 18x.

Combining these results, we get the final expression:

-45 + 18x

Keep in mind that when simplifying expressions or performing multiplication, we need to adhere to the rules for multiplication of numbers with different signs, as described earlier.

Final answer:

The product of -9(5-2x) is calculated by using the distributive property to multiply -9 by each term inside the parentheses, yielding 18x - 45.

Explanation:

The product of -9(5-2x) can be found by applying the distributive property of multiplication over subtraction. This property states that you multiply the term outside the parentheses by each term inside the parentheses. Here are the steps:

Multiply -9 by the first term inside the parentheses (5), which is -45.

Multiply -9 by the second term inside the parentheses (-2x), which gives us +18x (note that a negative multiplied by a negative gives a positive).

Combine these two products to get the final result, -45 + 18x, or 18x - 45.

This demonstrates the rules of multiplication where multiplying two numbers with opposite signs results in a negative product, and multiplying two numbers with the same sign results in a positive product.

Step-by-step explanation:

To find the range you would have to but the data(numbers) in order from least to greatest, then subtract the smallest number from the largest. The disadvantage of using range is that it does not measure the spread of the majority of values in a data set it only measures the spread between highest and lowest values. As a result, other measures are required in order to give a better picture of the data spread.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The cost of two sweaters is = $ 17.99

The cost of pair of slacks is = $ 25.50

So ,

The cost of two sweaters and pair of slacks = $ 17.99 + $ 25.50

                                                                         = $ 43.49

Now the equation will be ,

The tax percentage on the cost of purchase = 5 1/2 %

                                                                          = 5.5 %

The cost of purchase including the tax percentage =
The cost of two sweaters and pair of slacks x tax percentage

The cost of purchase including the tax percentage = 43.49 x ( 5.5/100 )

                                                                                     = $ 2.39195

So the equation will be ,

The total cost of purchase =
The cost of two sweaters and pair of slacks + cost of purchase including the tax percentage

The total cost of purchase = $ 43.49 + $ 2.39195

                                            = $ 45.88195

                                            ≈ $ 45.88

Hence , the total cost of Jack's purchase is $ 45.88

Solving the equation:

3x + 11 = k

SUBTRACT 11 from both sides:

3x + 11 = k

      -11    -11

You are then left with:

3x = k-11

DIVIDE 3 by both sides:

3x/3 = k-11/3

The original floor could be rectangle in shape.

If we consider the length of floor to be 'L' and width of floor to be 'W',

then area of original floor = length x width = LW.

And if its dimensions are dilated by scale factor of 4 to make new floor, then new length and width would become four times of older values. So new length would be '4L' and new width would be '4W'

Now area of new floor = length x width = 4L x 4W = 16LW.

It is clear that the area of new floor is 16 times of the area of original floor.

So, option C i.e. 16 is the final answer.

Answer:

A) 3

Step-by-step explanation:

The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.

Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.

We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.

Therefore, the option A gives the correct answer.

Answer: Hello mate!

the function f(x) = [x] is equal to the closest smaller or equal integer to the number x.

for example:

[1] = 1

[1.3] = 1

[1.9998] = 1

then, the closest smaller or equal integer to the number 3.6 is the number 3.

this means that f(3.6) = [3.6] = 3, then the right option is the first one.

Step-by-step explanation:

Here, the triangles has the legs 2.5 ft and 3 ft.

Since, by the Pythagoras theorem,

Hypotenuses of the triangle,

[tex]=\sqrt{2.5^2+3^2}=\sqrt{6.25+9}=\sqrt{15.25}\text{ feet}[/tex]

Now, let [tex]\theta_1[/tex] and [tex]\theta_2[/tex] are the angles opposite to the sides 2.5 and 3 respectively,

Hence, by the law of sine,

[tex]\frac{sin\theta_1}{2.5}=\frac{sin\theta_2}{3}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]

When,

[tex]\frac{sin\theta_1}{2.5}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]

[tex]\implies sin\theta_1=\frac{2.5}{\sqrt{15.25}}=0.64018439966 [/tex]

[tex]\implies \theta_1=39.8055710923 \approx 39.8^{\circ}[/tex]

Similarly,

[tex]\frac{sin\theta_2}{3}=\frac{sin90^{\circ}}{\sqrt{15.25}}[/tex]

[tex]\implies sin\theta_2=\frac{3}{\sqrt{15.25}}=0.76822127959  [/tex]

[tex]\implies \theta_2=50.1944289077 \approx 50.2^{\circ}[/tex]
