[tex]\boxed{\angle DBC=x=60^{\circ}}[/tex]

Hello! Remember to write complete questions in order to get good and exact answers. Here the figure is missing so I'll assume the arc measure of DBC is given in radian and you want it in degrees. By definition, an arc's measure is the measure of its central angle being a central angle an angle between two radii in a circle. Suppose that angle measures:

[tex]\angle DBC=\frac{\pi}{3}\ radian \\ \\ \\ So, \ by \ rule \ of \ three: \\\\ \\ \pi \ radian \rightarrow 180 \ degrees \\ \\ \pi/3 \ radian \rightarrow x \ degrees \\ \\ \\ x =\frac{180\pi}{3\pi}=60^{\circ} \\ \\ \\ Finally: \\ \\ \boxed{\angle DBC=x=60^{\circ}}[/tex]

Final answer:

The probability that the arrow will land on the purple section of the spinner is calculated by dividing the number of purple results (12) by the total number of results (60), resulting in a probability of 1/5 or 20%.

Explanation:

The question is asking about the probability of the arrow landing on the purple section of a spinner with four different colored sections (orange, red, blue, and purple), each with a different number of results (orange: 9, red: 15, blue: 24, purple: 12). To calculate this probability, you need to use the basic probability formula which is:

Probability of an event = (Number of ways the event can occur) / (Total number of possible outcomes)

So the probability that the arrow will land on the purple section is:

Probability of purple = Number of purple results / Total results = 12 / (9 + 15 + 24 + 12) = 12 / 60 = 1 / 5

Therefore, the probability is 0.2, or 20%.

hello :

f(x)=3x^2-6x+13

1)  a=3   and  b= -6

2)  the x coordinate of the vertex is : x= -b/2a    so :  x= -(-6)/6 = 1

3) the y coordinate by x= 1 is : f(1) = 3(1)²-6(1)+13 = 10

Answer:

D. 36 feet

Step-by-step explanation:

if Cassie's new ratio is 1:12 height-to-base, and her height is 3, plug that information into the ratio.

1:12 = 3:b

to go from 1 to 3, you multiply 1 by 3, so you will need to multiply 12 by 3 to get the new base.

3x12 = 36

Explanation: y1-y2/x1-x2 (-3 - 2/-2 - 3)

Answer:

  -2-2√3, -2+2√3

Step-by-step explanation:

Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:

  x(-4-x) = -8

  -4x -x^2 = -8 . . . . . eliminate parentheses

  x^2 +4x = 8 . . . . . . multiply by -1

  x^2 +4x +4 = 12 . . . add 4 to complete the square

  (x +2)^2 = 12

  x +2 = ±√12 = ±2√3

  x = -2±2√3

The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.

To find two numbers that multiply to -8 and add to -4, we can guess and check until we find a pair that satisfies both conditions. The two numbers in this case are -4 and 2.

The question is asking for two numbers that, when multiplied together, equal -8 and, when added together, equal -4. This falls under the category of quadratic equations. To solve this problem, we would typically use the formula "x = [ -b ± sqrt(b² - 4ac) ] / 2a", but in this case, it's easier to guess and check numbers. The two numbers that satisfy the conditions are -4 and 2. Their multiplication gives us -8 (-4*2) and their addition gives us -4 (-4+2).

Answer:

The height of the can is 4 inches.

Step-by-step explanation:

Cylinder:

Given that, the surface area of the soup can is 51.84 in².

The diameter of the can is 3 inches.

Then, radius of the can [tex]=\frac{Radius}{2}[/tex]

                                      [tex]=\frac32[/tex] inches

                                      =1.5 inches

Total surface area of the cone is = 2πrh+2πr²

                                                      [tex]=2\pi (1.5)h+2\pi (1.5)^2[/tex] in².

                                                      [tex]=2\pi (1.5)(h+1.5)[/tex]  in².

                                                      =3π(h+1.5)  in².

So,

3π(h+1.5)=51.84

[tex]\Rightarrow (h+1.5)=\frac{51.84}{3\pi}[/tex]

[tex]\Rightarrow h=\frac{51.84}{3\pi}-1.5[/tex]

⇒h=5.5-1.5

⇒h=4 inches

The height of the can is 4 inches.

Answer:

Let's us talk about the Hydro Power Plant that generates electricity by energy possessed in a mass of flowing water by virtue of it height.

Step-by-step explanation:

The hydo power plant utilizes

an hydraulic turbine which converts the energy of flowing water into mechanical energy of it rotating shaft . A hydroelectric generator (alternator) converts this mechanical energy into electricity. The operation of this alternator is based on the principles of Electro magnetic induction, that when a coil of conductor is moved past a magnetic field, it causes electricity generation. So when high energy water impinges on the blade of a turbine the energy is transformed to rotational motion of the shaft which is connected to the the alternator

When the alternator turns, coils attached to it move past the magnetic field hence this causes electricity to flow and a voltage to develop at the generator output terminals."

Answer:

Sample Response: Power plants generate electricity by turning a turbine. The turbine spins a generator, which produces electricity. Fossil fuels are burned to heat water, producing steam that turns the turbine. Nuclear power plants use fission to produce the thermal energy needed to produce steam. Wind and falling water are also used to turn turbines, which spin generators that produce electricity.

Final answer:

Using the Law of Cosines with the given sides and angle, we find that only one unique triangle can be drawn since a specific third side length can be determined, allowing only one possible triangle to exist.

Explanation:

To determine how many unique triangles can be drawn with side lengths of 12 cm and 16 cm and an included angle of 50°, we use the concept of triangle construction. The Law of Cosines allows us to find the range of possible third sides that could form a triangle:

c² = a² + b² - 2ab*cos(C),

where:

The solution to this equation will determine if we have a single unique triangle, more than one triangle, or no triangle at all. In this case:

c² = 12² + 16² - 2*12*16*cos(50°)

Calculating the value, we can then check if 0 < c < 28 (because for a triangle to exist, the sum of any two sides must be greater than the third side). If the third side falls within this range, a unique triangle can be drawn. As a triangle with two sides and an included angle will only yield one possible third side length, there can be only one unique triangle formed.

So, the answer is that with the given two sides and included angle, only one unique triangle can be drawn.

so the right answer is of option D.

The height of the pyramid is 11 cm

Step-by-step explanation:

Let the height of the pyramid be 'h'

Volume of the triangular pyramid= (1/3) (base area) (height of the pyramid)

110 = (1/3) (1/2) (10) (6) (h)

110 = (1/6) (60) (h)

110 = (10) h

h = 110/10

h = 11 cm

The height of the pyramid is 11cm

Answer:

  D.  If a is between 0 and 1, the image of the polygon is smaller than the polygon.

Step-by-step explanation:

The given transformation represents a dilation by a scale factor of 'a'. Every linear dimension of the image polygon will be a factor of 'a' times the corresponding dimension of the original.

When a > 1, the image is larger.

When a = 1, the image is congruent to the original (no sizes have changed).

When 0 < a < 1, the image is smaller. This description matches choice D.

The correct answer is D. If a is between 0 and 1, the image of the polygon is smaller than the original polygon.

Given that a polygon is graphed on a coordinate grid with (x, y) representing the location of a certain point of the polygon.

The polygon is transformed using the rule (x, y) → (ax, ay).

We need to determine the possible result of the transformation.

When a transformation rule (x, y) → (ax, ay) is applied to a polygon on a coordinate grid, the value of a determines the scaling factor of the image.

If a is greater than 1, the image of the polygon will be larger than the original polygon because the coordinates are multiplied by a value greater than 1, resulting in an expansion or enlargement of the shape.

If a is between 0 and 1, the image of the polygon will be smaller than the original polygon because the coordinates are multiplied by a value between 0 and 1, resulting in a contraction or reduction of the shape.

Therefore, statement D is correct.
