Answer:
the answer is a
Step-by-step explanation:
formula= (angle / 360) x π x (diameter / 2)^2
i this case we have the radius already so
= (240/360)*(pi)*(11)^2
=2/3(3.14)*(121)
= around 253.29
= which leads me to believe a is correct
Answer:
Solution given;
angle =240°
radius [r]=11cm
we have
length of arc =240°/360°×π*r²
=240°/360°×2×3.14*11²=253.29cm²
length of the arc is 253.29cm².

Two chords intersect in the interior of a circle. One chord is divided into two segments measuring 8 units and 9 units. The other chord is
divided into two segments, one of which measures 3 units.
What is the measure of the other segment?
Answer:
Step-by-step explanation:
1. When two chords intersect each other inside a circle, the products of their segments are equal. ... One chord is cut into two line segments A and B. The other into the segments C and D. This theorem states that A×B is always equal to C×D no matter where the chords are.
2. If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle . In the figure, m∠1=12(m⌢QR+m⌢PS) .
3. The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.

Given three squares of different areas, the perimeter of square A 2/3 the perimeter of square B and the perimeter of square B is 2/3 the perimeter of square C. if the area of Square A is 16 square units, what is the area of square C?
I’ll mark BRAINLIEST the first to answer my question :)
Area of square A = 16 cm
side of square A a1 = 4cm
side of square A = 2/3(2/3a3)
a1= 4/9a3
a3 = 9cm
Area of square C = 9×9= 81 Cm²

A rectangle has a length of (3x - 1) and a width of (x + 1). Part A Determine the perimeter and area of the rectangle as polynomials.
Answer:
Area of the rectangle = 3x² +2x-1
Perimeter of the rectangle = 8x
Step-by-step explanation:
Given
length = (3x - 1)
width = (x + 1)
Area of the rectangle= length * breadth
Area of the rectangle = (3x - 1) (x + 1)
= 3x²+ 3x - x-1
= 3x² +2x-1
Perimeter of the rectangle = 2( length + breadth)
= 2[(3x - 1) + (x + 1)]
= 2[3x - 1 + x + 1]
= 2[ 4x]
= 8x
How many \frac{1}{2} 2 1 - pound packages of cheese can the deli make with 1212 pounds of cheese?
Given:
Total cheese = 12 pound
Cheese in each package = [tex]\dfrac{1}{2}[/tex] pounds
To find:
The number of cheese packages.
Solution:
We need to divide the total amount of cheese by quantity of cheese in each package to find the the number of cheese packages.
[tex]\text{Number of cheese packages}=\dfrac{\text{Total cheese}}{\text{Cheese in each package}}[/tex]
[tex]\text{Number of cheese packages}=\dfrac{12}{\dfrac{1}{2}}[/tex]
[tex]\text{Number of cheese packages}=12\times \dfrac{2}{1}[/tex]
[tex]\text{Number of cheese packages}=24[/tex]
Therefore, there are 24 number of cheese packages.
The outer and inner diameters of a circular ring are
34 cm and 32 cm, respectively. Then, find the area of ring
Answer:
103.686cm^2
Step-by-step explanation:
Given data
Outer diameter= 34cm
Outer Radius= 34/2= 17cm
Area= πr^2
Area of outer ring= 3.142*17^2
Area of outer ring= 3.142*289
Area of outer ring= 908.038cm^2
inner diameter= 32cm
inner Radius= 32/2= 16cm
Area= πr^2
Area of outer ring= 3.142*16^2
Area of outer ring= 3.142*256
Area of outer ring= 804.352cm^2
Hence the radius of the ring is
=Area of outer - Area of inner
=908.038-804.352
=103.686cm^2

If f(x) = 3x + 4, what is the value of f(-4)?
Answer:
-8
Step-by-step explanation:
f(x) = 3x + 4
substitute -4 in place of x
f(-4) = 3*-4 + 4
f(-4) = -12 + 4
f(-4) = -8

Find the volume of the following
Answer:
22 ft³
Step-by-step explanation:
Applying,
V = 1/3(Ah).................... Equation 1
Where V = Volume of the pyramid, A = Area of the base, h = height of the pyramid.
But,
A = 1/2bl................ Equation 2
Where b = base of the triangle. l = height of the triangle.
Substitute equation 2 into equation 1
V = 1/6(blh).............. Equation 3
From the diagram,
Given: b = 3 ft, l = 4 ft, h = 11 ft
Substitute these values into equation 3
V = 1/6(3×4×11)
V = 1/6(132)
V = 22 ft³

Which proportion could be used to find the length of side b?
Answer:
[tex]\text{B. }\frac{\sin 31^{\circ}}{9.3}=\frac{\sin 85^{\circ}}{b}[/tex]
Step-by-step explanation:
In any triangle, the Law of Sines states that the proportion of the sine of each angle and its opposite side is maintained throughout all 3 angles and their corresponding sides of a triangle:
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex]
Thus, we have [tex]\implies \boxed{\text{B. }\frac{\sin 31^{\circ}}{9.3}=\frac{\sin 85^{\circ}}{b}}[/tex]

Answer:
-1.2
Step-by-step explanation:
3n + 5 = 1/2(11n + 16)
3n + 5 = 5.5n + 8
5 = 2.5n + 8
-3 = 2.5n
-3/2.5 = n
-1.2 = n
Hope this helps!
Answer:
[tex]n=-1.2[/tex]
Step-by-step explanation:
First, solve both sides of the equation:
[tex]3n+5=\frac{1}{2} (11n+16)[/tex]
[tex]3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16)[/tex] (Distribute)
[tex]3n+5=\frac{11}{2} n+8[/tex]
Then, subtract 11/2 n from both sides:
[tex]3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n[/tex]
[tex]\frac{-5}{2}n+5=8[/tex]
Now, subtract 5 from both the sides:
[tex]\frac{-5}{2} +5-5=8-5[/tex]
[tex]\frac{-5}{2} n=3[/tex]
For the last step, multiply both the sides by 2 / -5
[tex](\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)[/tex]
[tex]n=\frac{-6}{5}[/tex]
Convert it to decimal:
[tex]n=-1.2[/tex]

Line A (y = x + 2) is transformed into Line B (y=3x+1). Which best describes the new slope and y-intercept?
Answer:
The slope is steeper and the line is shifted downwards.
The y-intercept is shifted downwards.
Step-by-step explanation:
We proceed to demonstrate the transformation from the line A to line B:
1) [tex]y = x + 2[/tex] Given.
2) [tex]y = 3\cdot x + 6[/tex] Vertical dilation.
3) [tex]y = 3\cdot x +1[/tex] Vertical shift of the line in 5 units in the -y direction/Result
Hence, the answer is:
The slope is steeper and the line is shifted downwards.
The y-intercept is shifted downwards.
Someone help big ideas 8.6 number 20
Answers:
smaller = 45larger = 135============================================================
Explanation:
Let x and y be the two angles such that x < y. Also, we'll make both values to be positive numbers.
Since one angle is 1/3 of the other angle, this means
smaller angle = (1/3)*(larger angle)
x = (1/3)y
3x = y
y = 3x
The two angles add to 180 degrees since they are a linear pair. A linear pair of angles always forms a straight line.
x+y = 180
x+3x = 180
4x = 180
x = 180/4
x = 45
Use that x value to find y.
y = 3x
y = 3*45
y = 135
The two angles are x = 45 and y = 135
---------
Check:
x+y = 45+135 = 180
so the answer is confirmed.

What is the average rate of change for this exponential function for the interval from x = 7 to x = 8?
Answer:
4374
Step-by-step explanation:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374

Determine the intercepts of the line
y= 4x + 7
x-intercept: (____,___)
y-intercept: (____,___)
[tex] \huge\mathfrak{ \underline{Answer : }}[/tex]
The equation of line is
[tex] \hookrightarrow \: y= 4x + 7 [/tex]
let's plug the value of " x as 0 " to find the coordinate of y at the " x - intercept "
[tex]y = 4x + 7[/tex][tex]y = (4 \times0 ) + 7[/tex][tex]y = 7[/tex]therefore, the coordinates of x- intercept are :
[tex] \large \boxed{(0,7)}[/tex]
now, let's plug the value of " y as 0 " to find the coordinate of x at the " y - intercept "
[tex]y = 4x + 7[/tex][tex]4x + 7 = 0[/tex][tex]4x = - 7[/tex][tex]x = \dfrac{ - 7}{4} [/tex]therefore, the coordinates of y - intercept are :
[tex] \boxed{ \bigg( \frac{ - 7}{4} ,0 \bigg)}[/tex]
