Step-by-step explanation:
Answer:
64
Step-by-step explanation:
P.E.M.D.A.S. stands for parentheses, exponents, multiplication, division, addition, and subtraction
so first do the parentheses (3+7) = 10 which leaves 10×6+4 then since their is no exponents do multiplication which is 10×6=60 which leaves 60+4 finally since their is no division do addition 60+4=64
Considerando que cada semana se van acumulando los amigos de la semana anterior. ¿Cuántos amigos se fueron uniendo por semana ? Suponiendo que cada semana fueran nuevos amigos cuántos tendría en total? En este mismo supuesto ¿En qué semana alcanzara más de la mitad de Seguidores que acumulo en las doce semanas?
Answer:
1. Amigos nuevos cada semana: 7, 8, 4, 4, 5, 4, 3, 5, 8, 2, 7, 7
2. 418 amigos en total.
3. En la Semana 9 se alcanzan 247 amigos.
Step-by-step explanation:
He agregado una imagen adjunta con la tabla de datos necesarios para esta pregunta. En la misma se indican la cantidad de amigos o seguidores para cada semana, de un perfil de una red social hipotética.
1. Considerando que cada semana se van acumulando los amigos de la semana anterior. ¿Cuántos amigos se fueron uniendo por semana.
En este caso indica que los amigos se van acumulando cada semana, por lo que la tabla indica los amigos totales del perfil. Para saber cuantos se han agregado cada semana, debemos restar el valor de una semana dada con el valor de la semana anterior. Por ejemplo para la semana 1 indica 7 amigos y para la semana 2 indica 15 amigos, la cantidad de amigos nuevos en la semana 2 es:
semana2 - semana1 = 15 - 7 = 8 nuevos amigos
Los resultados para las semanas 1 a la 12 son:
7, 8, 4, 4, 5, 4, 3, 5, 8, 2, 7, 7
En el archivo excel adjunto (resultados.xlsx) se indican todos los resultados para las 12 semanas.
2. Suponiendo que cada semana fueran nuevos amigos ¿Cuántos tendría en total?
En este supuesto, la tabla de datos indica la cantidad de nuevos amigos cada semana, por lo que para calcular cuantos amigos tendrá en total luego de las 12 semanas se deben sumar todos los valores:
semana1 + semana2 + semana3 +...+...+semana12 = 418 amigos en total
3. En este mismo supuesto ¿En qué semana alcanzara más de la mitad de Seguidores que acumulo en las doce semanas?
Con el mismo supuesto anterior, primero debemos calcular la mitad de amigos totales que alcanzará. Ya hemos calculado que tendrá 418 amigos, por lo que la mitad será:
418÷2 = 209 amigos
Ahora debemos ir sumando los amigos semana a semana, hasta alcanzar un valor igual o mayor a la mitad (209). Eso nos indicará en que semana se supera mas de la mitad de seguidores. Haciendo la operación:
semana1+semana2+semana3+...+...
encontramos que en la semana 9 se alcanzan 247 amigos, superando la mitad calculada anteriormente.

What is the final amount if 1015 is decreased by 6% followed by a 19% increase?
Give your answer rounded to 2 DP. PLSE help
Answer:
1,123.30
Step-by-step explanation:
first of all, you are decreasing 1015 by 6 percent so it will be
1015 * 0.93 because you are decreasing it from the percentage
then, you are increasing it by 19 percent so you mulitply what you got on the previous calculation and multiply it by 1.19
943.95 * 1.19
and answer will be 1,123.30
Rewrite this percent as a decimal:

Using the function, g(x) = 5x - 2 and the domain below, state the range.
Domain: {-3, -1, 0, 2}
Answer:
{2-,-3,5.5}

Elvira, the cafeteria manager, has just received a shipment of new trays with the school logo prominently displayed in the middle of the tray. After unloading 4 cartons of trays in the pizza line, she realizes that students are arriving for lunch and she will have to wait until lunch is over before unloading the remaining cartons. The new trays are very popular and in just a couple of minutes 24 students have passed through the pizza line and are showing off the school logo on the trays. At this time, Elvira decides to divide the remaining trays in the pizza line into 3 equal groups so she can also place some in the salad line and the sandwich line, hoping to attract students to the other lines. After doing so, she realizes that each of the three serving lines has only 12 of the new trays. "That's not many trays for each line. I wonder how many trays there were in each of the cartons I unloaded?"
Help the cafeteria manager answer her question using the data in the story about each of the actions she took. Explain how you arrive at your solution.
Answer:
im willing to bet that there is 3 in each carton
(just a guess for the points also theres no multiple choice?)
The quantity of trays that were in each of the cartons the manager unloaded was 12 trays.
How many trays there were in each of the cartons I unloaded?To determine the quantity of trays in each carton, we need to analyze the given information step by step:
We know that 24 students have passed through the pizza line and received trays with the school logo.The remaining trays were divided into three equal groups for the salad line, sandwich line, and pizza line.Each serving line ended up with only 12 new trays.From these points, we can deduce the following:
Since 24 students passed through the pizza line, and each student received one tray, this means that 24 trays were taken from the initial shipment.After 24 trays were taken, an equal number of trays were distributed to the salad line, sandwich line, and the remaining trays were kept in the pizza line.Each serving line ended up with 12 new trays. Since the trays were divided equally among the three lines, each line received the same number of trays.Now, let's solve for the number of trays in each carton.
Let's assume that the number of trays in each carton is "x."
We know that 24 trays were taken initially, and each serving line ended up with 12 trays. So, we can set up the equation:
24 + 12 + 12 + 12 = 4x
48 = 4x
Dividing both sides of the equation by 4:
12 = x
Therefore, there were 12 trays in each of the cartons that were unloaded.
To summarize, each carton that Elvira unloaded contained 12 trays.

Given f(x) = 2x 2 +4x -3, find f(2a+3)
Answer:
f(2a + 3) = 8a² + 20a + 27
Step-by-step explanation:
f(x) = 2x² + 4x - 3
f(2a + 3) = 2(2a + 3)² + 4(2a + 3) - 3
f(2a + 3) = 8a² + 12a + 18 + 8a + 12 - 3
f(2a + 3) = 8a² + 20a + 27
The value of f(2a+3) for the given function f(x) = 2x² + 4x - 3 will be 8a² + 20a + 27.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given the function f(x) = 2x² + 4x - 3
⇒ f(2a + 3) = 2(2a + 3)² + 4(2a + 3) - 3
⇒ f(2a + 3) = 2(4a² + 9 + 6a) + 8a + 12 - 3
⇒ f(2a + 3) = 8a² + 18 + 12a + 8a + 12 - 3
⇒ f(2a + 3) = 8a² + 20a + 27.
Hence "The value of f(2a+3) for the given function f(x) = 2x² + 4x - 3 will be 8a² + 20a + 27".

5) 6x + 5y =-15
Need help it’s writing linear equations!!
Answer:
the Slope is -6/5 and y is (0,-3)
Step-by-step explanation:
we need to put this equation in y = mx + b
6x - 5y = -15 u will subtract 6x from both sides
5y = -6x -15...divide both sides by 5
and then simplify
y = -6/5x - 3
and when u graph its will be (0,-3)
ur slope(m) = -6/5 and ur y int (b) = -3
2x+3y=15
x+y=6
work out the value of x and y
Answer: x=3, y-3
Step-by-step explanation:
I would use elimination
Multiply second equation by 2
2x + 2y = 12
2x + 3y = 15
Subtract both
-1y = -3, y = 3
Plug in 3 for y in any equation
x + 3 = 6, x = 3
Final answer: x = 3, y = 3
