How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is
[tex]A=\dfrac{\theta}{360^\circ}\pi r^2[/tex]
Where, [tex]\theta[/tex] is the central angle in degrees.
Putting r=10 and [tex]\theta=45^\circ[/tex], we get
[tex]A=\dfrac{45^\circ}{360^\circ}\pi (10)^2[/tex]
[tex]A=\dfrac{1}{8}\pi (100)[/tex]
[tex]A=12.5\pi[/tex]
Therefore, the area of the sector is 12.5π sq. inches.

40% Ehrnhardt, 13% petty, 18% waltrip, 29% Gordon
(a) Order the popularity of the choices from greatest to least.
(b) It was estimated that 360 people were surveyed. If this was true, how many people would have voted for Ehrnhardt? Round to the nearest whole number. Show your work.
(c) 65 people voted for Petty. Was the estimate of total voters from Part (b) accurate? Explain.
Answer:
(a) Earnhardt (40%), Gordon (29%), Waltrip (18%), and Petty (13%)
(b) 144, work is below
(c) No
Step-by-step explanation:
(b)
convert 40% to a decimal by dividing by 100 = 0.4
360 x 0.4 = 144 people voted for Earnhardt
(c) converting Petty's percentage to a decimal, we get 0.13. 360 x 0.13 = 46.8, or 47 people, not 65.
Waltrip's percentage, 0.18 x 360 = 64.8, or 65 people.

400-36v^2 can someone find the factor?
Answer:
-4(3v - 10)(3v + 10)
Step-by-step explanation:
You must find the factored form of 400 - 36v^2.
You can rearrange this to - 36v^2 + 400 to make it less confusing.
So you have - 36v^2 + 400.
The next step is to see what you can take out of this. You can take out a GCF, a greatest common factor. This is basically a number that goes into both 36 and 400. This number is 4.
36 / 4 = 9 and 400 / 4 = 100.
Since it is a negative 36, you need to take out a negative 4.
So you put a 4 outside parenthesis and divide - 36 / 4 and 400 / 4.
-4(9v^2 - 100).
Now you must factor the inside of the parenthesis.
9v^2 - 100.
This is the same as 9v^2 + 0v - 100.
What are 2 numbers that multiply to get -100 and add to get 0?
These numbers are -10 and +10.
2 terms that multiply together get 9v^2 are 3v and 3v.
So the answer is:
-4(3v - 10)(3v + 10).
This is the factored form.

Answer:
x = 51°
Step-by-step explanation:
The sum of all angles in a triangle is 180°. (Angle Sum Property)
We already know 2 angles, the right angle and the 39°.
(x + 90 + 39)° = 180°
(x + 129)° = 180°
x = (180 - 129)°
x = 51°
Answer:
X= 70.5
Step-by-step explanation:
The area of a triangle is 180
180 - 39 = 141
141/2 = 70.5
70.5 + 70.5 + 39 = 180

Answer:
The three gallon container is the better buy. See below.
Step-by-step explanation:
8 pints
2 pints = 1 quart.
8 pints = 4 quarts.
4 quarts = 22.64 Divide by 4
1 quart = 5.66
3 gallons.
1 gallon = 4 quarts
3 gallons = 12 quarts.
The cost of 1 quart = 54.48/12 = 4.54
2x + 3y = 5x - y
Complete the missing value in the solution to the equation.
( _ , 0 )
Answer:
(4y/3, 0) or if there are no options, it's probably (0, 0)
Step-by-step explanation:
2x + 3y = 5x - y
So we are trying to find the missing value in the solution (_, 0)
We are looking for the x-intercept/root if the coordinate is in this way: (_, 0)
So to find the root, We are solving for x
2x + 3y = 5x - y
First, subtract 5x from bth sides
2x + 3y - 5x = 5x - y - 5x
2x + 3y - 5x = -y
Add like terms
-3x + 3y = -y
Now, subtract 3y from both sides
-3x + 3y - 3y = -y - 3y
-3x = -4y
Divide both sides by -3
-3x/-3 = -4y/-3
x = -4y/-3
We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.
So x = 4y/3
Now that we found x, we can input it to the coordinate
(4y/3, 0)

Where are my smart friends?? I had $13.00. My Mom gave me $10.00. My Dad gave me $30.00. My Aunt, My Uncle, and grandma gave me $100.00. I had another $7.00. How much did I have? I won against Nancy Boyd
Answer:
This would bring you to $160.00. This is because you initially had $20.00, because of the $13 and $7. Then, your family gave you a total of $140.00, and 140 + 20 = 160.
Step-by-step explanation:
The total amount of money he had is $160 and this can be determined by using the arithmetic operations and the given data.
Given :
I had $13.00. My Mom gave me $10.00. My Dad gave me $30.00. My Aunt, My Uncle, and grandma gave me $100.00. I had another $7.00.The arithmetic operations can be used in order to determine the total amount of money he had.
The initial amount of money he had is:
= $13 + $7
= $20
His Mom gave him $10.00. So, the total amount of money now he had is:
= $20 + $10
= $30
His Dad gave him $30.00. So, the total amount of money now he had is:
= $30 + $30
= $60
His Aunt, Uncle, and Grandma gave him $100. So, the total amount of money now he had is:
= $60 + $100
= $160

Answer:
x² + 4x - 12
Step-by-step explanation:
(x+6)(x-2)
=> (x*x) + (x*-2) + (6*x) + (6*-2)
=> (x²) + (-2x) + (6x) + (-12)
=> x² - 2x + 6x - 12
=> x² + 4x - 12

Danielle constructs a scale model of a building with a rectangular base. Her model is 2 inches in length and 1 inch in width. The scale on the model is 1 inch = 47 feet. What is the actual area, in square feet, of the base of the building? in ft2
Answer: The actual area of the base of the building = 4418 square feet.
Step-by-step explanation:
Dimensions of model: 2 inches in length and 1 inch in width.
The scale on the model is 1 inch = 47 feet.
Actual length = 2 x (47 feet) = 94 feet
Actual width = 1 x 47 feet = 47 feet
Actual area of base of building = (Actual length) x (Actual width)
= 94 x 47 square feet
= 4418 square feet
Hence, the actual area of the base of the building = 4418 square feet.

Step-by-step explanation:
180-134=46
Answer:
They're both 46 degrees
Step-by-step explanation:
Angle b and 134 are right next to each other so they're supplementary and have to equal 180 degrees.
180-134=46, and since Angle c is is a vertical angle with Angle b, it also equals 46^^

From the question given above, the following data were:
Angle A = 21 °
Hypothenus = AC = 13
Opposite = BC =?
The length of BC can be obtained by using sine ratio as illustrated below:
Sine A = Opposite /Hypothenus
Sine 21 = BC / 13
0.3584 = BC / 13
Cross multiply
BC = 0.3584 × 13

Answer:
Parallel
Step-by-step explanation:
Let the required lines be y-x = 5 and y = x-1
If y-x = 5

For the line y = x - 1
The slope m is also 1
Since the slope of both lines are the same, hence both liens are parallel
