En las elecciones de 2012 hubo 3candidatos .Manuel ,enrique y josefina en dicha eleccion se emitieron 900000 manuel obtuvo 500 votos menos que enrique y 8000 mas que josefina . cuantos votos obtuvo cada candidato identifica las magnitudes involucradas representa matematicamente las magnitudes escribe una expresion algebraica que represente el problema
Answer:
Las magnitudes involucradas son las cantidades de votos obtenidos por Manuel, Enrique y Josefina.
La expresión algebraica que representa el problema es:
[tex]3\cdot x = 907500[/tex]
Manuel obtuvo 302500 votos, Enrique logró 303000 votos y Josefina consiguió 294500 votos.
Step-by-step explanation:
Sean [tex]x[/tex], [tex]y[/tex] y [tex]z[/tex] la cantidad de votos obtenidos por Manuel, Enrique y Josefina. Recomendamos leer oración por oración y traducir cada parte a términos matemáticos para obtener las ecuaciones necesarias para la resolución del problema:
1) En dicha elección se emitieron 900000 votos:
[tex]x+y+z =900000[/tex] (Ec. 1)
2) Manuel obtuvo 500 votos menos que Enrique:
[tex]x = y-500[/tex] (Ec. 2)
3) Manuel obtuvo 8000 votos más que Josefina:
[tex]x = z + 8000[/tex] (Ec. 3)
Ahora despejamos los votos de Enrique y Josefina (Ecs. 2, 3):
[tex]y = x+ 500[/tex]
[tex]z = x-8000[/tex]
Y sustituimos las variables en (Ec. 1):
[tex]x+(x+500)+(x-8000) = 900000[/tex]
La expresión algebraica que representa el problema es:
[tex]3\cdot x = 907500[/tex]
Luego, obtenemos los votos de Manuel:
[tex]x = 302500[/tex]
Ahora, los votos de Enrique y Josefina:
[tex]y = 303000[/tex]
[tex]z = 294500[/tex]
En consencuencia, Manuel obtuvo 302500 votos, Enrique logró 303000 votos y Josefina consiguió 294500 votos.
2/3y - 2/5 = 5, what is the value of y? *
Answer:
y=3.6 or 18/5 or you can turn it into any other fraction
Step-by-step explanation:
2/3y - 2/5 = 5
+2/5 +2/5
2/3y = 27/5
multiply by 2/3 on both sides
y=3.6 or 18/5 or you can turn it into any other fraction

Last month you had 8 wins while playing fortnite. This month you had 5. What was your percent of change?
Answer:
-37%
Step-by-step explanation:
work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100

Point B(-8,5) is dilated from the origin by scale factor r=1/2 what are the coordinates of point B?
Answer:
The coordinates of point B are (-4,5/2)
Step-by-step explanation:
The transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.
What is a transformation?When a point is relocated from its original place to a new location, it is changed. Different transformations include translation, rotation, reflection, and dilation.
You can dilate figures on the coordinate plane. The origin is commonly used as the dilatation center. You can identify the points in the picture if you deform a figure centered at the origin by multiplying the coordinates of the points in the preimage by the scale factor.
We have been given that Point B(-8,5) is dilated from the origin by scale factor r = 1/2
The scale factor i.e. 0.75 is multiplying the coordinates of the points B(-8,5)
So the coordinates of point B = (-8/2, 5/2)
Thus, the transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.

Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 82 mmHg and a standard deviation of 12 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are no more than 94 mmHg?
Answer:
68%
Step-by-step explanation:
Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 82 mmHg and a standard deviation of 12 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are no more than 94 mmHg?
Empirical rule states that:
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
We are given:
mean of 82 mmHg and a standard deviation of 12 mmHg.
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
μ - σ
82- 12
= 70mmHg
μ + σ.
= 82 + 12
= 94 mmHg
simplify the expression and write in standard form

L.B. Johnson Middle School held a track and field event during the school year. Miguel took part in a four-person shot put team. Shot put is a track and field event where athletes throw (or “put”) a heavy sphere, called a “shot,” as far as possible. To determine a team score, the distances of all team members are added. The team with the greatest score wins first place. The current winning team’s final score at the shot put is 52.08 ft. Miguel’s teammates threw the shot put the following distances: 12.26 ft., 12.82 ft., and 13.75 ft. Exactly how many feet will Miguel need to throw the shot put in order to tie the current first-place score? Show your work.
Answer:
11.25 ft
Step-by-step explanation:
To determine a team score, the distances of all team members are added.
The current winning team’s final score at the shot put is 52.08 ft.
So, in order to tie the score Miguel's team must equal the above score.
The total score before Miguel's throw was 12.26+12.82+13.75= 38.83 ft
so , Miguel will have throw 52.08-38.83= 11.25 ft in order to tie the score.

What would the equation of y = x + 3 be if it is translated seven units up?
Answer:
y=x+10 would be the answer
Answer:
y = x + 10
Step-by-step explanation:
A graph translated 7 units up is just x + 7. However, we already have an equation, so we need to add 7 to 3 first.
y = x + (3 + 7)
y = x + 10

leaves at 9:10 and averages 65 mph on the way. The situation is modeled by
this system, where x is the number of hours after Samantha leaves and y is
the distance each will travel:
y = 60x + 10
y = 65x

a.) y - 11 = (x+3)
Slope of line
Answer:
m = 1
Step-by-step explanation:
y - 11 = (x+3) can be compared to the gneral point-slope formula
y - k = m(x - h), where (h, k) is a point on the line.
Notice that the coefficient of (x + 3) is 1; therefore we know immediately that the slope of the line is m = 1.
The Local concert Hall has 48 concert scheduled the season each concert has the same amount of tickets available for sale there is a total of 4560 tickets how many tickets are available for each concert
Answer:
The number of tickets available for each concert is 95 tickets.
Step-by-step explanation:
the total available tickets for all the concert = 4560 tickets
number of concert = 48 concert
If all the concert have the same number of tickets, then the number of tickets for each concert is given as;
number of tickets for each concert = 4560 tickets / 48
the number of tickets for each concert = 95 tickets
Therefore, the number of tickets available for each concert is 95 tickets.
