¿Cuál es la razón en la que está segmentada la línea que une a los puntos A(-2,3) y B(4,-1) si se sabe que el Pr es (0,5/3)?
Answer:
Entonces la proporción es 1/2
Step-by-step explanation:
Aquí, en esta pregunta, queremos encontrar la razón que divide al segmento AB en la razón (0,5 / 3).
Usamos la fórmula de división interna para esto;
Sea la relación m / n Matemáticamente, la fórmula de división que da lugar a (0,5 / 3) es la siguiente;
(x, y) = mx2 + nx1 / (m + n), my2 + ny1 / (m + n)
En este caso particular;
(x1, y1) = (-2,3)
(x2, y2) = (4, -1)
(x, y) = (0,5 / 3).
Así que hagamos las sustituciones; (0,5 / 3) = m (4) + n (-2) / (m + n), m (-1) + n (3) / (m + n)
(0,5 / 3) = (4m -2n) / (m + n), (-m + 3n) / m + n.
Por tanto, equiparemos términos;
4m-2n / (m + n) = 0
4m -2n = 0
4m = 2n
n = 4 m / 2
n = 2 millones •••••••• (i)
(3n -m) / (m + n) = 5/3
3 (3n -m) = 5 (m + n)
9n - 3m = 5m + 5n
9n -5n = 3m + 5m
4n = 8m
n = 8 m / 4 n = 2m ••••••• (ii)
Podemos ver que ambos son iguales;
n = 2 m 1 = 2m / n
divide ambos lados por 2
m / n = 1/2.

can someone answer this for me pls
Answer: Lin is the most consistent and I would want to have them on my team.
Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since
range = max - min
So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.
what does b equal can i please have your help
Hey there! I'm happy to help!
These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.
8x-8=5x+25
Subtract 5x from both sides.
3x-8=25
Add 8 to both sides.
3x=33
Divide both sides by 3.
x=11.
Have a wonderful day! :D
Answer:
x = 11
∠B = 80
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x - 8°
∠B = 5x + 25°
8x - 8° = 5x + 25°
8x - 5x = 25 + 8
3x = 33
x = 33/3
x = 11
plugin x into ∠B = 5x + 25°
∠B = 5x + 25°
∠B = 5(11) + 25°
∠B = 80

Teah was selling candy bars for a fundraiser. She spent $25 on a box of candy bars and sold each candy bar for $2.50. Her profit was $75. Teah wrote the equation 2.5c−25=75 for this situation, and she found c=40.
Which statement is true about the solution c=40?
The solution c=40 is the selling cost of each candy bar, in dollars.
The solution c=40 is the selling cost of a box of candy bars, in dollars.
The solution c=40 is the number of candy bars Teah sold.
The solution c=40 is the amount in dollars that Teah spent on a box.
The solution c=40 is the profit in dollars Teah made from each candy bar.
Answer: The solution would be C
Step-by-step explanation:
If we multiply 40 candy bars by $2.50 we would get the answer of $100 because that is how much she made from selling candy bars. . Then we would have to subtract that answer by $25 because that is how much the box cost. $100 minus $25 is equal to $75. So the answer would be option C

What is the point-slope form of a line with slope 6 that contains the point
(1,2)?
A. y + 2 = 6(x - 1)
B. y+ 2 = 6(x+1)
C. y-2 = 6(x-1)
O D. x+ 1 = 6(y+2)
Answer:
The answer is option CStep-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (1,2) and the slope is 6
The equation of the line in point slope form is
[tex]y - 2 = 6( x - 1)[/tex]Hope this helps you

2. Give recursive definitions for the following sets. a. The set of all strings over {a, b} containing at least one "a". b. The set of odd-length binary strings that end with 00.
Answer and explanation:
Recursive is related to repeat the definition, rule, and procedure.
a) The set of all strings over {a,b} containing at least one a.
Let x is a string containing at least one a: x=a and y= b
Sets of union of XY and yx will be (XY) (yx) = (a,b) (b, a)
b) The set of odd length binary strings that end with 00
There is a regular expression compared with two 00, which is surrounded by 0+1 with at least two 0s.
The sphere shown below is placed in a full overflow cup and sinks to the bottom. How much water is displaced by the sphere?Lector inmersivo
(1 Punto)
A. 51.0 mL
Option 2
C. 88.6 mL
D. 407.7 mL
B. 66.5 mL
Answer:
A. 51.0 mLStep-by-step explanation:
Given
The sphere with the diameter of 4.6It displaces the amount of water equal to its volume
Volume of the sphere:
V = 4/3πr³V = 4/3π(d/2)³ = 1/6πd³V = 1/6*3.14*4.6³ = 50.939 ≈ 51.0 cm³ = 51.0 mlCorrect option is A. 51.0 mL
Answer:
A
Step-by-step explanation:
We are given a diameter of 4.6
4.6 / 2 = 2.3 (radius)
Volume of a sphere [ V = 4/3πr² ]
V = 4/3π(2.3)²
V = 4/3π(5.29)
V = 4/3(38.20438)
V ≈ 51
Best of Luck!
Which of these could be the volume of a rectangular box?
Answer:Understand the volume of a rectangle equals it's length x width x height. If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.

Answer:

Step-by-step explanation:
We know that the perimeter of a square is [tex]2l + 2w[/tex], where l is the length and w is the width.
We also know that the perimeter of a triangle is all of its sides added up.
Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.
Basically:
[tex](3x - 3) + (3x - 3) + (x - 3) + (x - 3) = (2x - 1) + (2x - 1) + (2x)[/tex]
We can combine like terms to get a less scary equation.
[tex]8x - 12 = 6x - 2[/tex]
Our goal is to now isolate x so we can find it's value.
Add 2 to both sides:
[tex]8x - 10 = 6x[/tex]
Subtract 6x from both sides:
[tex]2x - 10 = 0[/tex]
Add 10 to both sides:
[tex]2x = 10[/tex]
Divide both sides by 2:
[tex]x = 5[/tex]
Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.
Let's do it on the triangle.
[tex]6x-2[/tex] (remember, this is our simplified version of the triangle)
[tex]6(5) - 2\\\\30 - 2\\\\28[/tex]
