if the length of an arc is 12π inches and the radius of the circle us 10 inches, what is the measure of the arc?
Answer:
The measure of arc is 216°
Step-by-step explanation:
Length of arc, L = 12π inches
Radius of the circle, R = 10 inches
Formula: [tex]\theta=\dfrac{L}{R}[/tex]
Where, [tex]\theta[/tex] in radian.
By substituting L and R into formula.
[tex]\theta=\dfrac{12\pi}{10}[/tex]
[tex]\theta=\dfrac{6\pi}{5}[/tex]
Now we change radian to degree
[tex]\text{Degree }=\dfrac{\text{Radian}}{\pi}\times 180^\circ[/tex]
[tex]\text{Degree }=\dfrac{6\pi}{5\pi}\times 180^\circ[/tex]
Central angle = 216°
Hence, The measure of arc is 216°

From a barrel of colored marbles , you randomly select 5 blue , 2 yellow , 3 red , 4 green , and 2 purple marbles. Find the expreimetal probability of randomly selecting a marble that is NOT yellow .
1. 9 / 16
2. 7 / 8
3. 8 / 9
4. 3 / 4
Answer:
4/5
Step-by-step explanation:
From your experiment of drawing 20 marbles you now have a proportion of non-yellow marbles to total marbles and from that you can come up with an experimental probability that you'll draw a non-yellow marble.
P(not yellow) = 16/20

If lines L and M are parallel in the given diagram and angle 5 is 132°, what is the measure of angle 3?
Since lines L and M are parallel, corresponding angles such as angle 5 and angle 3 will be equal. Thus, if angle 5 is 132°, angle 3 will also be 132°.
Explanation:This question concerns parallel lines and the angles formed by a transversal cutting across them. The lines L and M in the given diagram are parallel. Parallel lines have a special property where corresponding angles are equal. If angle 5 measures 132°, then the corresponding angle, angle 3, also measures 132°, because of this property of parallel lines.

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equation, B. the extraneous solution is x = 7, C. the valid solutions are x = 7 and x = 4, or D. the extraneous solution is x = 4
Answer:
D. the extraneous solution is x = 4
Step-by-step explanation:
You want to know the statement that describes if there is an extraneous solution to the equation √x-3 = x-5.
SolutionA straightforward (blind) solution to the problem proceeds by squaring both sides and solving the quadratic:
x -3 = x² -10x +25
x² -11x +28 = 0
(x -7)(x -4) = 0 ⇒ x = 4 or x = 7
When you try these solutions in the original equation, you get ...
√(4 -3) = 4 -5 ⇒ 1 = -1 . . . . . x = 4 is an extraneous solution, choice D
√(7 -3) = 7 -5 ⇒ 2 = 2 . . . . . x = 7 is the solution
DomainThe square root function is only defined for non-negative values, so the left side of the equation is only defined for x ≥ 3.
The left side of the equation produces non-negative values. The right side of the equation will have non-negative values only for x ≥ 5.
Considering the domain of the equation is x ≥ 5, we know that x = 4 cannot be a solution. It can be ignored. This value only arises because squaring the radical allows values of x that require the root to be negative.
__
Additional comment
The attached graph shows the only solution is x=7, the value that makes the difference between the sides of the equation be zero. We find it useful to write radical equations in the form f(x) = 0, making the x-intercepts of the graph of f(x) be the solution(s). The graphing calculator does not graph the function where it is undefined, so the domain restrictions are automatically accommodated.
If the volume of a sphere is 36 cubic units, what is the radius?
A. 3 units
B. 4√3 units
C. 9 units
The radius of the sphere is 2.048 units .
The volume of a sphere is :
4/3πr³Volume = 36substituting into the formula:
36 = 4/3πr³
36 × 3 = 4 πr³
108 = 4πr³
πr³ = 27
r³ = 27/π
r³ = 8.59436
r = 2.048
Hence, the radius of the sphere is 2.048 units .

complete question:
Write an expression in simplest form that represent the total amount.
Sal scored g goals this season. Ben has scored four times as many goals as Sal. Chun has scored three fewer goals than Ben.
a. 9g - 3
b. 3g - 9
c. g - 4g
d. 3g + 9
Answer:
a. 9g - 3
Step-by-step explanation:
Sal scored g number of goals this season . Ben has scored 4 times as many goals as Sal . Chun has scored 3 fewer goals than Ben. There goals can be expressed as follows
Sal's goal = g
Ben's goal = 4(g) = 4 × g = 4g
Chun's goal = 4g - 3
sum of their goals = g + 4g + (4g - 3)
sum of their goals = g + 4g + 4g - 3
sum of their goals = 9g - 3
How many sides does a regular polygon have if each exterior angle measures 30?
The number of sides that the polygon with each exterior angle measuring 30° has is 12.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of all the exterior angles of a regular polygon is always equal to 360°. Therefore, the measure of an exterior angle for a regular polygon is given as,
[tex]\theta = \dfrac{360^o}{n}[/tex]
where n is the number of sides.
Given that the measure of the exterior angle is 30°. Therefore, the number of sides will be,
[tex]\theta = \dfrac{360^o}{n}\\\\ 30^o = \dfrac{360^o}{n}\\[/tex]
n = 12
