10x + 8 = 21

x = 1.3

Step-by-step explanation:

In pentagon ABCDE,

AB = DE = 2x + 3 and BC = CD = x + 1

Perimeter of pentagon ABCDE = 21

4x + 2(2x + 3) + 2(x + 1) = 21

4x + 4x + 6 + 2x + 2 = 21

[tex] \purple {\boxed {\bold{10x + 8 = 21}}} [/tex]

Percent means out of 100

33%

Answer: 33%

Explanation: A ratio that compares a number to 100 can be written as a percent. So in this problem, since the figure has 33 out of 100 boxes shaded, we have the ratio 33/100 which can be written as 33%.

You know that the sum of all of the angles in a triangle must be equal to 180º, we can make an equation.

55º + 67.5º + 3xº + 14º = 180º

Combine like terms:

136.50º+ 3xº = 180º

Subtract 136.50º

3xº = 180º - 136.50º

3xº = 43.50º

Divide by 3

xº = 43.50º / 3º

x = 14.50º

What is the radius of J. A. 24.8
B. 6.2
C. 10.8
D. 12.4

Answers

Answer:

12.4 units

Step-by-step explanation:

The diameter of circle J is represented by KN. Half of KN is KJ and JN which means these represent the radius. Since JN equals 12.4 and JN is the the radius, then the radius of circle J is 12.4 units which is answer choice D.

The radius of the given circle is 6.2 unit. So option B is correct.

What is the radius?

A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. It is a crucial component of spheres and circles and is frequently abbreviated as "r". When discussing multiple radiuses at once, the plural form of radius is "radii". The diameter of a circle or sphere is the longest line segment connecting all points on the opposite side of the centre, and the radius is equal to half of the diameter in length. It can be written as d/2, where d is the circle's or sphere's diameter. Look at the illustration of a circle below that depicts the connection between radius and diameter.

Given that,

A circle,

which contains diameter KN of length 12.4 unit

and chord 10.8 unit.

The radius = ?

It is known that, the length of the radius is half of the diameter of the circle,

R = D/2

= 12.4/2

= 6.2

Therefore, the length of the radius is 6.2 unit.

Answers

Answer:

-32

Step-by-step explanation:

Look at the attachment

Functions can be represented as equations and graphs.

The value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32

From the graph, we have the following values.

[tex]\mathbf{f(0)= 1}[/tex]

[tex]\mathbf{g(-8)= -6}[/tex]

So, we have:

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 \times 1 + 4 \times -6}[/tex]

Simplify

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 -24 }[/tex]

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -32 }[/tex]

Hence, the value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32
