D. 276°
Answers

Answer:
138°
Step-by-step explanation:
The measure of arc ABC is the measure of the corresponding central angle, ∠ANC. That angle is shown as 138°, so the measure of arc ABC is 138°.
Measure of an angle ABC is 111 degrees i.e. [tex]m[/tex]∠ABC = 111 degrees.
Angle subtended by an Arc of a circle-Theorem
The angle subtended by an arc at the center of the circle is double the angle subtended by the same arc at the circumference of the circle.
According to the given question
The angle subtended at the center of circle, i.e. ∠ANC = 138 degrees.
The exterior angle at the center is (360 - 138)degrees = 222 degrees
by angle subtended by an Arc of a circle theorem
[tex]m[/tex]∠ABC = [tex]\frac{222}{2}[/tex] [tex]= 111 degrees[/tex]
Hence, [tex]m[/tex]∠ABC = 111 degrees.

Answers
Answer:
4(3r+4)
Step-by-step explantion:
The factorized form of the given expression is 4(3r+4).
The given expression is 12r+16.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
Factorization of the expression 12r+16 is as follows
Here, in terms 12r=2×2×3×r and 16 =2×2×2×2, we have 4 has common factor
So, 4(3r+4)
Hence, the factorized form of the given expression is 4(3r+4).

need to make to the dividend (125x3 - 8)?
(125x3 – 8) = (5x – 2)
Answers
Answer:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]
Step-by-step explanation:
Given
[tex]Dividend = 125x^3 - 8[/tex]
[tex]Divisor = 5x - 2[/tex]
Required
Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x
[tex]\frac{125x^3}{5x} =25x^2[/tex]
Write [tex]25x^2[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]25x^2[/tex]
[tex]= 125x^3 - 50x^2[/tex]
Subtract from 125x^3 - 8
i.e.
[tex]125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8[/tex]
Step 2:
Divide 50x^2 by 5x
[tex]\frac{50x^2}{5x} = 10x[/tex]
Write [tex]10x[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]10x[/tex]
[tex]= 50x^2 - 20x[/tex]
Subtract from 50x^2 - 8
i.e.
[tex]50x^2 - 8 - (50x^2 - 20x) = 20x - 8[/tex]
Step 3:
Divide 20x by 5x
[tex]\frac{20x}{5x} = 4[/tex]
Write [tex]4[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]4[/tex]
[tex]= 20x - 8[/tex]
Subtract from 20x - 8
i.e.
[tex]20x - 8 - (20x - 8) = 0[/tex]
Hence:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]

Answer:
0.527
Step-by-step explanation:
From the question,
The sequence is Geometry Progression (G.P)
Tₙ = arⁿ⁻¹.......................... Equation 1
Where n = number of term, a = first term, r = common ratio
Given: n = 7, a = 6, r = 2/3
Substitute these values into equation 1
T₇ = 6(2/3)⁷⁻¹
T₇ = 6(2/3)⁶
T₇ = 6(64/729)
T₇ = 384/729
T₇ = 0.527
Hence, the 7th term of the sequence is 0.527

X=-6
Answer:
1. x=11
2. x=39
3. x= 12
4. x=6
5. x=-6
Step-by-step explanation:
1. x+4= 10+2x-17
FG=GH
x+4=2x-7
11=x
2. 11x+71=12x+32
subtract from both sides
39=x
3. All angles of a triangle add to 180.
39+57+(8x-12)=180
96+(8x-12)=180
8x-12=84
8x=72
divide both sides by 8
x=9
4. Vertical angles are equal
68=11x+2
66=11x
divide
6=x
5. (114+x)+(37+x)=139
Add like terms
151+2x=139
subtract
2x=-12
x=-6
