Answer:

X = 109

Step-by-step explanation:

I = 5 – 2 (180) = 540  

100 + 102 + 108 + 121 = 431

540 – 431 = 109

X= 109

The value of the angle x will be 109 degrees.

A polygon is a closed polygonal chain made up of a finite number of straight-line segments that are joined to form a planar figure in a geometry or polygonal circuit. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.

Given that an irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.

The value of the angle x will be calculated as below:-

100 + 102 + 108 + 121 + x = 540

x = 540 – 431

x= 109

Therefore, the value of the angle x will be 109 degrees.

The solution to the inequality is x < -5.

To solve the inequality -2(5x + 1) > 48, we need to isolate the variable x. Let's simplify the equation step by step:

-2(5x + 1) > 48

Start by distributing -2 to the terms inside the parentheses:

-10x - 2 > 48

Next, isolate the variable by adding 2 to both sides of the inequality:

-10x - 2 + 2 > 48 + 2

-10x > 50

Now, divide both sides by -10, remembering to flip the direction of the inequality when dividing by a negative number:

(-10x) / (-10) < 50 / (-10)

x < -5

This means that any value of x that is less than -5 will satisfy the original inequality. To express the solution using an inequality symbol, we write x ∈ (-∞, -5). The symbol (-∞, -5) represents the interval of all real numbers less than -5, including -5 itself.

Answer:

1/3

Step-by-step explanation:

Answer:

1/2 % 1/3 = 3/2 or 1 1/2 cups of 1/3 are equal to 1/2 cup. Therefore, one and a half 1/3 cups are equal to 1/2 cups.

Step-by-step explanation:

The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.

To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

Answer:

∠ ABC = 49°

Step-by-step explanation:

the chord- tangent angle ABC is half the measure of the intercepted arc AB

∠ ABC = [tex]\frac{1}{2}[/tex] AB = [tex]\frac{1}{2}[/tex] × 98° = 49°

Given parameters:

Distance = 320miles

Average speed  = 69miles per hour

Unknown;

A motion equation  = ?

Given that D should represent Distance

                  h number of hours traveled by Joe

Speed is a physical quantity defined as the distance divided by time taken.

It is mathematically expressed as;

             Speed  = [tex]\frac{Distance}{time taken}[/tex]

Now substitute D for distance and h for the number time;

          Speed  = [tex]\frac{D}{h}[/tex]

So distance;

          D = Speed x h

For this journey;

         D = 69h

The equation is D = 69h

Answer:

The answer is B. D=320-69h

The pairings between the mathematical descriptions and their corresponding algebraic expressions:

1. The absolute value of twice a number increased by 11: |2x + 11|

  This expression represents the absolute value of the sum of twice a number (2x) and 11. The vertical bars indicate the absolute value operation, which ensures that the result is always positive or zero.

2. The square root of the difference of the square of a number and 11: [tex]\sqrt{(x^2 - 11)}[/tex]

  This expression represents the square root of the difference between the square of a number ([tex]x^2[/tex]) and 11. The square root function (√) returns the positive square root of the expression within the parentheses.

3. The quotient of two times a number and -11: -2x / 11

  This expression represents the division of -2x (twice a number multiplied by -1) by 11. Dividing by 11 results in a quotient that may be positive, negative, or zero.

4. The sum of the square root of two times a number and 11[tex]\sqrt{(2x) + 11}[/tex]
