Work Shown:
Focus on the angles at the bottom right
Those two angles add to 180 since they form a straight line. We consider them supplementary angles.
x+(4x-20) = 180
5x-20 = 180
5x = 180+20
5x = 200
x = 200/5
x = 40
Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)

For the data set 62, 73, 74, 75, 76, the mean is 72. What is the mean absolute deviation?
A. The mean absolute deviation is 4
B. The mean absolute deviation is 20
C. The mean absolute deviation is 5
D. The mean absolute deviation is 72
plz help i need to know asap
Answer: A. The mean absolute deviation is 4
Step-by-step explanation:
Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.
Differences
72-62= 10
72-73= 1
72-74= 2
72-75= -3
72-76= -4
add the absolute values...
10+1+2+3+4=20
divide by 5 because that is how many numbers in set...
20/5=4

Answer:
B and D are correct.
Step-by-step explanation:
First, we find the length of ALL the sides using the Pythagorean Theorem.
16² + b² = 20²
256 + b² = 400
b² = 144
[tex]\sqrt{144}[/tex] = 12
Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.
A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.
Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.
Answer:
The answer is B and D.
Step-by-step explanation:
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC = √(20)^2-(16)^2
= √400-256
= √144
= 12
Now, Sinθ = opposite side/hypotenuse = AB/AC
= 16/20
Cosθ = adjacent side/hypotenuse = BC/AC
= 12/20
Therefore, A and D are the correct options.
You're very welcome! ;)

Step-by-step explanation:
To find the circumference of a circle, the formula is [tex]C=2\pi r[/tex], with "C" being the circumference and "r" being the radius.
In question 13, the radius (r) is shown as 3ft. When you put this into the equation, it should look like this:
[tex]C=2\pi (3)[/tex]
Simplify.
[tex]C=6\pi[/tex]
Follow the same steps in questions 14 and 15. In 14, 9 is the diameter, which makes the radius 4.5.
The final answers are shown above.

Answer:
A. 60°
Step-by-step explanation:
∠BEC = 1/2 arc BC = 32°
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
arc CD = 2 x ∠CED = 2 x 30° = 60°
The measure of the arc CD of the circle is 60°
Given data:
The central angle is an angle with two arms and a vertex in the middle of a circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
And, Central Angle = 2 x Angle in other segment
So,
∠BEC = 1/2 arc BC = 32°
The measure of the angle ∠CED is determined as:
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
So, the measure of the arc from the central angle is:
arc CD = 2 x ∠CED = 2 x 30° = 60°
Hence , the measure of arc CD = 60°

A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.
Answer:
6m * 4m * 2m
Step-by-step explanation:
Given that :
Cubic volume = 48 m³
Possible dimension if none of the dimensions is 1 m
Volumetric Dimension = (length * width * height)
The product of the three dimensions must give 48m³
Constraint : none of the dimensions has a volume of 1 m.
Hence, possible dimension :
6m * 4m * 2m = 48m²
Hence, one possible dimension is :
6m * 4m * 2m

The equations of two lines are y = -x - 6 and 2x - 3y = -2. What is the value of the y in the solution for this system of linear equations?
Answer:
x = - 4
Step-by-step explanation:
y = -x - 6
2x - 3y = -2
Insert the first equation y = -x-6 into the second 2x - 3y = -2 .
2x - 3 (-x-6) = -2
2x +3x + 18 = -2
5x = -2 - 18
5x = - 20
x = - 20/5
x = - 4

Answer: A. 5x+x+18 = 180
Step-by-step explanation:
For B you need to find the value of x first.
5x + x + 18 = 180 is your equation.
Combine like terms: 5x+x = 6x
Equation should now look like this
6x + 18 = 180
Subtract 18 to both sides 180-18 = 162
Do 162/6 = 27
X = 27

The area of the circle is equal to 144π square inches.
What is the area of the circle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,
Area of circle = πr²
Circumference of the circle = 24π
2πr = 24π
r = 12
The area of the circle will be calculated as:-
Area = πr²
Area = π x ( 12 )²
Area = 144π square inches.
Hence, the area is 144π square inches.

find the value of x in a triangle. x-20, x+10, x-20
The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
