In linear equation, -1.15  is the value of 21 over 4 − 32 over 5.

What in mathematics is a linear equation?

An algebraic equation B. y=mx+b (where m is the slope and b is the y-intercept) containing simple constants and first-order (linear) components, such as the following, is called a linear equation. The above is sometimes called a "linear equation in two variables" where x and y are variables.

                                An equation with only one variable is called a univariate linear equation. It contains the expression Ax + B = 0. where A and B are any two real numbers and x is an ambiguous variable with only one possible value. 

(21/4) - (32/5)

=   21 * 5 - 32 * 4/ 20

=  105 -  128/20

= -1.15

Step-by-step explanation:

the side length = √173 = 13.1529464..= 13.15 in.

According to the solution we have come to find that, The area of the partial ring is arctan(11/R) x 22R square centimeters.

what is concentric circles?

Concentric circles are circles that share the same center point. This means that their circumferences are all the same distance away from the center point, and they all have the same radius. In other words, if you draw two or more circles with the same center point, they are concentric circles. The term "concentric" comes from the Latin word "concentricus," which means "having a common center."

Concentric circles can be used in many applications, including architecture, engineering, mathematics, and art. For example, they can be used to create patterns or designs, to mark distances or angles, or to create circular structures such as arches or domes. They are also used in measuring tools such as compasses and protractors, which use concentric circles to determine angles and distances.

Let's denote the outer radius of the ring as R and the inner radius as r. Let the central angle of the partial ring enclosed by DAB be θ in radians.

(a) Properties and definitions:

A circle is a set of points in a plane that are equidistant from a given point called the center.

A radius is a line segment connecting the center of a circle to a point on the circle.

A tangent is a line that touches a circle at only one point.

The angle formed by a tangent and a radius at the point of contact is 90 degrees.

Strategy:

We need to find the central angle θ in radians, given the angle formed by DAB.

Then we can use the formula for the area of a partial ring to find the area of the shaded region.

(b) Formula:

The area of the partial ring is given by:

Area of Partial Ring = (θ/2π) x π(R²- r²)

(c) Calculation:

We can find θ using the properties of circles and tangents. Since DAB is a chord of the outer circle, we know that the angle formed by the chord and the tangent at point D is 90 degrees. Let's denote the point of contact between the tangent and the outer circle as E. Then, we have:

angle AED = 90 degrees (angle formed by a tangent and a radius)

angle EAD = angle EAB (angles in the same segment)

angle EAB = angle BAD (angles subtended by the same chord)

angle BAD = θ/2 (half of the central angle)

Therefore, we have:

θ = 2 x angle BAD = 2 x (angle AED - angle EAD) = 2 x arctan(11/R)

Now we can substitute the values of θ, R, and r into the formula for the area of the partial ring:

Area of Partial Ring = (θ/2π) x π(R^2 - r²)

= (2 x arctan(11/R) / 2π) x π((R+11)^2 - R²)

= arctan(11/R) x 22R

Thus, the area of the partial ring is arctan(11/R) x 22R square centimeters. Note that we do not need to know the value of R to calculate the area, as it only appears in the form of the ratio 11/R.

The area of the composite figure is 111 square units.

A composite figure is a 2D shape or figure that is made up of two or more simpler shapes or figures combined together. These simpler shapes can be any combination of polygons, circles, or other curves.

Composite figures are often formed when two or more basic shapes are put together to create a more complex shape. For example, a figure that consists of a rectangle and a triangle placed together is a composite figure.

To find the area of a composite figure like this, we can break it up into simpler shapes and then find the area of each shape and add them together.

First, we can see that the shape consists of three triangles and a rectangle:

Triangle 1: (0,3), (2,3), (2,7)

Triangle 2: (-7,7), (-7,6), (5,-6)

Triangle 3: (5,1), (-1,-2), (-5,2)

Rectangle: (-3,5), (0,3), (-7,7), (-7,6)

To find the area of each triangle, we can use the formula:

Area = 1/2 * base * height

For Triangle 1, the base is 2 - 0 = 2 and the height is 7 - 3 = 4. So the area is:

Area of Triangle 1 = 1/2 * 2 * 4 = 4

For Triangle 2, the base is 5 - (-7) = 12 and the height is 7 - (-6) = 13. So the area is:

Area of Triangle 2 = 1/2 * 12 * 13 = 78

For Triangle 3, we can see that it is a right triangle with sides of length 6, 6, and 8. So the area is:

Area of Triangle 3 = 1/2 * 6 * 8 = 24

To find the area of the rectangle, we can use the formula:

Area = length * width

The length is the distance between (-7,7) and (-7,6), which is 1. The width is the distance between (-7,7) and (-3,5), which is 5. So the area is:

Area of Rectangle = 1 * 5 = 5

Finally, we can add up the areas of all the shapes to get the total area:

Total Area = Area of Triangle 1 + Area of Triangle 2 + Area of Triangle 3 + Area of Rectangle

Total Area = 4 + 78 + 24 + 5

Total Area = 111 square units

Therefore, the area of the composite figure is 111 square units.

Answer:

The width is 4 cm

The length is 12 cm.

Step-by-step explanation:

Area of a rectangle

Given a rectangle of width W and length L, its area is calculated as follows:

\(A=W\cdot L\)

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:

L = 3W

Substituting into the formula of the area:

\(W\cdot L=48\)

\(W\cdot 3W=48\)

Simplifying:

\(3W^2=48\)

Solving:

\(W^2=48/3=16\)

\(W=\sqrt{16}=4\)

The width is 4 cm. Find the length:

L=3W=3*4= 12

The length is 12 cm.

Answer:

length= 12 width=6

Step-by-step explanation:

when adding perimeter you add the length and width twice each so divide 36 by two and get 18

if the length is twice the width then you could make the equation w+2w=18

by adding like terms you get 3w=18

to get n by itself you divide 18 by 3 and get w=6

if the width is 6 and the length is twice that then the length is 12

Answer:

A=72

Step-by-step explanation:

The length of a rectangle is TWICE it's width meaning 2 times. (Note that L= length, W=width, and A=Area)

L=2w

4w+2w=36

6w=36 <- ( 6 is width)

then

2x6=12

Then

12x6=72

So the area of the rectangle is 72.

Hope that makes sense!

Answer:

Length = 4 feet

Step-by-step explanation:

Let the length of a rectangle be x.

Width is 1 feet shorter than the length, b = x-1

The area of the rectangle is 12 sq feet.

The area of a rectangle is given by :

A = length × width

So,

\(x(x-1)=12\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x+3)(x-4)=0\\\\x=-3\ and \ x=4\)

Neglecting the negative side, the length of the rectangle is equal to 4 feet.

The value of angle LAF in the intersecting chords is determined as  104⁰.

The value of angle LAF is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

Also this theory states that arc angles of intersecting secants at the center of the circle is equal to the angle formed at the center of the circle by the two intersecting chords.

m∠LAF = ¹/₂ (arc LF + arc YS)

From the diagram, we have arc LF = 160⁰ and YS = 48⁰

m∠LAF = ¹/₂ (160 + 48)

m∠LAF = 104⁰

Thus, the value of angle LAF is calculated by applying intersecting chord theorem.

Answer:

Chau served 63 orders.

Elsa served 16 orders.

Felipe served 21 orders.

Step-by-step explanation:

Given information:

Define the variables:

Create a system of equations from the given information and defined variables:

\(\begin{cases}e+c+f=100\\c=3f\\e=f-5\end{cases}\)

Substitute the second and third equations into the first equation and solve for f:

\(\implies e+c+f=100\)

\(\implies (f-5)+3f+f=100\)

\(\implies 5f-5=100\)

\(\implies 5f=105\)

\(\implies f=21\)

Substitute the found value of f into the second equation and solve for c:

\(\implies c=3f\)

\(\implies c=3(21)\)

\(\implies c=63\)

Substitute the found value of f into the third equation and solve for e:

\(\implies e=f-5\)

\(\implies e=21-5\)

\(\implies e=16\)

Therefore:

Let us assume that,

→ Elsa = x

→ Felipe = x + 5

→ Chau = 3x + 15

Now the required value of x,

→ x + x + 5 + 3x + 15 = 100

→ 5x + 20 = 100

→ 5x = 100 - 20

→ x = 80/5

→ [ x = 16 ]

Then the orders each serve is,

→ Elsa = x = 16

→ Felipe = x + 5 = 16 + 5 = 21

→ Chau = 3x + 15 = 48 + 15 = 63

Hence, the above one is correct.

The given triangle  ∆QRT is isosceles triangle.

What is isosceles triangle?

  Triangles with two equal sides are referred to as isosceles triangles. Also equal are the two angles that face the two equal sides. To put it another way, "An isosceles triangle is a triangle with two congruent sides." Assume that the sides AB and AC of the triangle ABC are equal, in which case the triangle ABC is an isosceles triangle with B = C. According to the theorem, "if the two sides of a triangle are congruent, then the angle opposite to them is also congruent."

Here the given points are Q(-2,-1) , R(1,5) , T(-8,-4).

Using distance formula

Now , The Distance between the points can be measure as :

D=\(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

QR = \(\sqrt{(1+2)^2+(5+1)^2}\)

=>QR=\(\sqrt{3^2+6^2} = \sqrt{9+36} =\sqrt{45}=3\sqrt{5\) unit

Now RT = \(\sqrt{(-8-1)^2+(-4-5)^2} =\sqrt{9^2+9^2} \\\)

=>RT=\(\sqrt{81+81}=\sqrt{162} = 9\sqrt{2}\) unit

Now TQ  = \(\sqrt{(-2+8)^2+(-1+4)^2} =\sqrt{6^2+3^2} \\\)

=>TQ=\(\sqrt{36+9}=\sqrt{45}=3\sqrt{5}\) unit.

Here QR=TQ then
