You spin a spinner with 9 equal spaces numbered 1 through 9. What is the probability that the spinner lands on a 5 or a multiple of 3? I HAVE 5 MINS
Answer:
4/9
Step-by-step explanation:
The probability that the spinner lands on a 5 or a multiple of 3 will be 0.4444 or 44.44%.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
You spin a spinner with 9 equal spaces numbered 1 through 9.
Then the probability that the spinner lands on a 5 or a multiple of 3 will be
The total number of the event will be
Total events = 9
The favorable event will be
Favorable = 1 {5} and 3 {3, 6, 9}
Then the probability will be
P = 1/ 9 + 3/ 9
P = (1 + 3) / 9
P = 4/9
P = 0.4444
P = 44.44%

Plss help I don't understand A circle has a diameter that extends from (2,6) to (-6,-8). What are the coordinates the
center of the circle
Answer:
(-2, -1)
Step-by-step explanation:
The centre of a circle is located at the mid-point of any diameter, hence we take the average of the coordinates of the end-points.
Cx = (2-6)/2 = -2
Cy = (6-8)/2 = -1
So the centre is located at (-2, -1)

Answer:
a ≈ 14.39
Step-by-step explanation:
7² + a² = 16²
49 + a² = 256
49 - 49 + a² = 256 - 49
a² = 207
√a² = √207
a = 14.3874945699
a ≈ 14.39

Find the average rate of change of a function that contains the points (-2,3) and (2,5)
Answer: [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Rate of change are typically found using [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex].
[tex](x_{1}, y_{1}) = (-2, 3)\\(x_{2}, y_{2}) = (2, 5)\\\\\frac{5-3}{2-(-2)} =\frac{2}{2+2} =\frac{2}{4} =\frac{1}{2}[/tex]
Therefore, the rate of change(aka slope) is [tex]\frac{1}{2}[/tex].
When solving the equation 6x - 8 = 12, the first step is to move the
constant, 8, to the right side by adding 8 to both sides. What is the
equation after step one?*
6x - 8 = 12 + 8
14x - 8 = 20
6x = 12 + 8
6x = 20
Answer:
6x= 12+8

Figure 1 shows a paperweight made from a hollow hemisphere and a hollow cone. The paperweight contains sand so that the sand exactly fills the hemisphere. The radius of the hemisphere is equal to the radius of the base of the cone. The height of the cone is 15cm and the volume of the cone is 180π cm3 Figure 2 below shows the paperweight after it has been turned upside down. Diagram NOT accurately drawn h cm Figure 2 The height of the sand in the cone is h cm. Find, to 3 significant figures, the value of h.
Answer:
13.95 cm
Step-by-step explanation:
the volume of the cone =
⅓× π r². h = 180 π
⅓×π r²×15 = 180 π
(eliminate π)
=> 5r² = 180
r² = 180/5 = 36
r=√36 = 6 cm
the volume of the sand = ½×4/3 π r³
= ⅔× π ×6³ = 144π cm³
the ratio of the volume :
144π/180π = 0.8
so the value of h = ³√0.8 x 15 = 0.93× 15
= 13.95 cm

3. When looking at an expression and/or equation, how can we tell that we need to distribute?
4. When solving an equation, if you get the solution, x=0, how many solutions to the equation are there?
(One solution, no solution, or infinite solutions)
5. When solving an equation, if you get 5 = 11, what does this mean? (One solution, no solution, or infinite
solutions)
6. When solving an equation, if you get 5 = 5, what does this mean? (One solution, no solution, or infinite
solutions)
Answer:
Step-by-step explanation:
1) a variable term contains a variable. If x is a variable
5x is an example of a variable therm
2) a constant therm is not a variable
3 is an example
3) for example when a number multiply a sum or a difference between a constant and a variable
Example:
2(x-3) = 5(x+4)
4) one solution: only if x is equal to 0 the equation is true
5) no solution: the equation can’t be true for ever value of the variable
6) infinite solutions: the equation is ever true for every value of the variable

We can denote this increase with the function [tex]y=3^x\cdot 100[/tex], where [tex]y[/tex] is value after [tex]\frac{x}{9}[/tex] years.
Substituting [tex]x=36[/tex], we get:
[tex]3^4\cdot 100=\boxed{\$8,100}[/tex]
Answer:
8,100
Step-by-step explanation:
The first 9 years would be 300, then 18 years would be 900, and 27 years it would be 2,700, and finally after 36 years it would be 8,100.

The figure shows Triangle ABC and some of its transformed images on a coordinate grid:
A coordinate plane is shown. Triangle ABC Is formed by the points 2 commas 5, 2 comma 3, and 4 commas 3. Triangle 2 is formed by the points negative 3 commas 5, negative 3 commas 3, and negative1 comma 3. Triangle 1 is formed by the points negative 4 commas 5, negative 4 commas 3, and negative 6 commas 3. Triangle 3 is formed by the points negative 6 commas 2, negative 4 commas 2, and negative 4 commas 0. Triangle 4 is formed by the points 2 commas negative 1, 4 commas negative 1, and 4 commas negative 3.
Which of the four triangles was formed by a translation of Triangle ABC?
1
2
3
4
Answer:
Triangle 2
Step-by-step explanation:
The translation is a type of transformation, where the figure is just translated or simply moved from its original place.
The figure is not rotated or dilated but simply moved.
Here, we can see that only figure or triangle 2 is like the triangle ABC. Other triangles have undergone other transformations.
So, the correct answer is triangle 2.
