Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.

Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.

Observa las siguientes imágenes formadas por círculos:

Figura 1 (un circulo) Figura 2 (5 círculos)

-¿Cuántos círculos tendrá la Imagen 10?
-¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7? ¿Puedes saberlo sin necesidad de encontrar la cantidad de círculos de cada imagen? ¿Cómo?

Answers

1.En 10 figuras habrá 37 puntos si te fijas en las imágenes lo único que hace es agregar 4 puntos a cada uno como la tercera imagen tiene 9 puntos hize 9 + 7x 4= 37
2.la imagen 12 tendrá 45 puntos y la 7 tendrá 25 puntos
La diferencia de puntos entre la figura 7 y 12 serán seran 20 puntos
-si lo pude saber sin la necesidad de encontrar la cantidad de los círculos de las imágenes porque cada ves vamos agregando 4 puntos

Veremos que en la imagen 10 hay 37 circulos, y la diferencia entre las imagenes 12 y 7 es de 20 circulos.

¿Como encontrar el patrón?

Primero, debemos contar la cantidad de circulos que tenemos en las imagenes mostradas.

En la primera, tenemos 1 circulo.En la segunda, hay 5 circulos.En la tercera, hay 9 circulos.En la cuarta, hay 13 circulos.

Entonces podemos ver que en cada imagen se agregan 4 circulos, es decir tenemos una secuencia aritmetica, de tal forma que la imagen número N tendremos:

[tex]C_N = 1 + (N - 1)*4[/tex]

Entonces, cuantos circulos hay en la imagen 10? para ver eso reemplazamos N por 10.

[tex]C_{10} = 1 + (10 - 1)*4 = 37[/tex]

¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7?

Para ver esto calculamos:

[tex]C_12 - C_7 = (1 + (12 - 1)*4) - (1 + (7 - 1)*4) = 11*4 - 6*4 = 20[/tex]

Es decir, la image 12 tiene 20 circulos más que la imagen 7.

Answers

Answer:

2%

Step-by-step explanation:

Calculate annual interest amount first:

                annual interest x 9/12=21

                Annual interest =21x12/9

                 annual interest amount=$28

calculate annual interest rate

                1400 x interest rate = annual interest

               $1400 x interest rate = $28

Answers

Answer:

37 1/8

Step-by-step explanation:

The problem probably assumes direct variation

y=kx

IF so, then plug in the values and solve for k

27=k(8)

k = 27/8

y= (27/8)x.  Now let x = 11

y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8

y = 37 1/8

the problem is making some assumption about the relation between x and y.  The simplest assumption that's likely is direct variation,  that x and y are linearly related.  The graph is a straight line through the origin with slope = 27/8

Harper is working two summer jobs, making $19 per hour lifeguarding and making $8 per hour walking dogs. In a given week, she can work at most 7 total hours and must earn a minimum of $80. If x x represents the number of hours lifeguarding and y y represents the number of hours walking dogs, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

We know that:

She makes $19 per hour of lifeguarding.

She makes $8 per hour walking dogs.

She can work at most 7 hours per week.

She must earn a minimum of $80 per week.

If x represents the number of hours lifeguarding and y represents the number of hours walking dogs, the inequalities will be:

x + y ≥ 7 hours.

(this says that she can work at most 7 hours per week)

x*$19 + y*$8 ≥ $80

(this says that she can earn a minimum of $80)

Then the system of inequalities is:

x + y ≥ 7 hours.

x*$19 + y*$8 ≥ $80

To graph these two we can write them as lines in standard form and simply graph both inequalities, the solution of the system will be the intersection between the solutions of each inequality.

Here we also should add the inequalities:

x ≥ 0

y ≥ 0

So we only look at the first quadrant.

The graph can be seen in the image below: (the dark blue is the solution region for the first inequality, the light blue one is the solution region for the second inequality)

 

One possible solution can be:

x = 4 and y = 1

or

x = 4 and y = 2

and there are a lot of other possible solutions.

By what percent did his average change? has US foreign policy been a positive or a negative for international diplomacy, since 1980? Music and the BrainFrom the beginning of recorded history, music has been created and enjoyed by people. Even early man carved flutes from bones. Thomas Jefferson was known to play his violin to help him formulate the most effective word choices as he wrote the Declaration of Independence. Albert Einstein, considered one of the most intelligent men who ever lived, also played the violin. He was said to have figured out his most challenging mathematical formulas by playing his violin. Today scientists are discovering that the study of music, playing an instrument, or participating through singing can actually help develop our brains. No wonder Einstein and Jefferson, among many, found music helpful in problem solving.There was a time in Americas history when music was a centerpiece of family life. There were no televisions, radios, or other forms of electronic entertainment. Social life often involved someone playing the piano or another instrument while guests sang along or listened for enjoyment. Therefore, if parents could afford the opportunity, their children were encouraged to learn how to play an instrument. Taking music lessons did not mean a child was expected to become a professional musician. However, it usually meant the kids learned the daily discipline of practice.Recent brain research has shown some surprising benefits as a result of formal musical training. Learning to play a musical instrument appears to develop parts of the brain that can even influence academic results. The studies indicate that the earlier a child begins training, the more benefits there are. One such study showed that children who began musical studies before the age of seven had a more developed brain in the region where language production and auditory processing take place. Scientists believe there is mounting evidence to show that early musical training can improve brain function.A research team from Northwestern University observed that to achieve the positive brain development from musical training, music students had to be active participants. There were differences found between the kids who attended a more passive music appreciation class, and the ones who learned to play instruments. It was the active production of music that rewired the brain. Using electrodes on the students heads, scientists were able to see how actively the brain responded when students generated music.Neuroscientists have suggested that playing an instrument, especially at an early age, can improve how the brain interprets sensory information. Music (singing or playing an instrument) also positively affects memory. Apparently, music activates both the right and left sides of the brain simultaneously and this activity increases efficiency in processing information. In one study, researchers found the areas of the brain that affect language skill and executive function were more developed in musically trained students. The executive function is the planning center of your brain, where you figure out what must get done, and how to do it in the time that exists.A special community music program in a low-income area of Los Angeles showed a higher success rate of students going on to college than students in the area who did not participate in this music education. A team of researchers was asked to offer scientific evidence for this compelling distinction. The study concluded that there were significant improvements in reading scores for the children who attended music classes regularly and were actively engaged for a period of two years, compared to those who did not participate.What tone does the statement "The executive function is the planning center of your brain" give in Paragraph 5?an insistent tonea critical tonean instructive tonea forceful tone Consider the following polynomial:-2a^3b^2+5ab^5+7b4+8What is the degree, leading coefficient, constant, and leading term of this polynomial? *(Can you please show or tell me step by step on how u got there, please) Friends and fellow citizens: I stand before you tonight under indictment for the alleged crime of having voted at the last presidential election, without having a lawful right to vote.
