Find the area of the shape.
Either enter an exact answer in terms of T or use 3.14 for it and enter your answer as a decimal.
Answers
The answer is 37.68
We need to find the area of the sector of the circle.
There is a missing part in the upper left part of the circle.
The upper left part central angle measure 90 degree becuase it has a perpendicular sign.
Using central angle and arc theorem, the central angle equal the arc measure so that arc measure is 90 degrees.
There is 360 degrees in a circle so using arc addition,
the rest of the arc measure 270 degrees.
We can use this formula to find the area of the sector
[tex] \frac{x}{360} \times \pi \times {r}^{2} [/tex]
where x is the measure of the central angle and r is the radius.
Plug 270 in for x. The radius is 4.
[tex] \frac{270}{360 } \times \pi \times {4}^{2} [/tex]
[tex] \frac{3}{4} \times \pi \times 16[/tex]
[tex]12\pi[/tex]

b = 76°
Step-by-step explanation:
Hi there,
It is important to know that the sum of all the angles in any triangle equals 180°.
For this problem, we can write the following equation:
32° + 72° + b° = 180°
104° + b° = 180°
b° = 76°

I need to solve for x btw these are corresponding angles
Answers
Step-by-step explanation:
As we know corresponding angles are equal so
6x - 100° = 2x + 4° < being corresponding angles>
6x - 2x = 100 ° + 4°
4x = 104°
x = 104° / 4
x = 26°

To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=21.2[/tex]
Therefore, the rate of change is 21.2 dollar and cents per hour.

Step-by-step explanation:
You need to distribute the 4x to the rest of the equation so the equation will become 48x-20xy+4xz, this is because 4x * 12 = 48x and 4x*-5y =-20xy and it's xy because x comes before y in the alphabet and then lastly 4x * z same thing it's gunna be xz, so the answer is 48x-20xy+4xz.

What is the HCF of 108 and 270?
Answers
Answer:
gcf, hcf, gcd (108; 270) = 54 = 2 × 3^3: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.
Step-by-step explanation:
Hope this helps :)
The highest common factor (HCF) of two given numbers is 54.
What is the highest common factor?The largest number among all the common factors of the provided numbers is the GCF or HCF of two or more numbers. Their GCF is the largest integer that can be used to divide the two natural integers x and y without leaving any remainders.
The given numbers are 108 and 270.
The prime factors of the numbers 108 and 270 are
108=2×2×3×3×3
270=2×3×3×3×5
So, HCF is 2×3×3×3=54
Therefore, HCF of 108 and 270 is 54.

The coordinates of the triangle after the rotation is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the triangle be represented as ΔLMN
L ( -2 ,4 ) , M ( -2 , 8 ) , and N ( -6 , 4 )
Now , the rotation angle is = 90° counterclockwise about the origin
Let the coordinates of the rotated triangle be ΔL'M'N'
where , 90° counterclockwise rotation: (x,y) becomes (-y,x)
So , L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
Hence , the rotated triangle is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )

Solve with elimination
Answers
Answer:
5
Step-by-step explanation:
{
3x−y=2
2x−y=3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x−y=2,2x−y=3
Subtract 2x−y=3 from 3x−y=2 by subtracting like terms on each side of the equal sign.
3x−2x−y+y=2−3
Add −y to y. Terms −y and y cancel out, leaving an equation with only one variable that can be solved.
3x−2x=2−3
Add 3x to −2x.
x=2−3
Add 2 to −3.
x=−1
Substitute −1 for x in 2x−y=3. Because the resulting equation contains only one variable, you can solve for y directly.
2(−1)−y=3
Multiply 2 times −1.
−2−y=3
Add 2 to both sides of the equation.
−y=5
Divide both sides by −1.
y=−5
The system is now solved.
x=−1,y=−5
