Answer:

Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.

Step-by-step explanation:

Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales (es decir, un sistema de ecuaciones en donde cada ecuación es de primer grado), en el cual se relacionan dos o más incógnitas.

En los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.

En este caso se debe establecer un sistema de ecuaciones, donde las variables son:

Siendo 30 preguntas en el examen, se tiene la ecuación:

x + y= 30

Por cada respuesta correcta se obtenían 5 puntos y por cada respuesta incorrecta o pregunta no contestada, se perdían 2 puntos. Teodolindo obtuvo 94 puntos en este examen. Entonces se representa esta situación mediante la expresión:

5*x - 2*y= 94

Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{x+y=30} \atop {5*x-2*y=94}} \right.[/tex]

El método de sustitución consiste en despejar o aislar una de las incógnitas (por ejemplo,  x ) y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita,  y . Una vez resuelta, calculas el valor de  x  sustituyendo el valor de  y  calculado.

Entonces, despejando el valor de x de la primer expresión obtienes:

x= 30 -y

Reemplazando en la segunda ecuación obtienes:

5*(30 -y) - 2*y= 94

Resolviendo:

5*30 - 5*y - 2*y= 94

150 - 5*y - 2*y= 94

- 5*y - 2*y= 94 -150

-7*y= -56

y= (-56)÷(-7)

y= 8

Reemplazando el valor de y obtenido en la expresión x= 30 -y se obtiene:

x= 30 - 8

x=22

Step-by-step explanation:

Answer:

a) The rule is;

f = 5.75 + 2d

b) f = $33.75

Step-by-step explanation:

Here, we want to write a rule

The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest

We have this as;

f = 5.75 + 2(d)

f = 2d + 5.75

Now for 15 downloads;

first download is $5.75, remaking 14 is at a rate of $2 per one

Thus, we have the fee value as;

f = 5.75 + 2(14)

f = 5.75 + 28 = $33.75

Answer:

37.5%

Step-by-step explanation:

Given data

Initila Price= $2.25

3.5% of  $2.25

=3.5/100* 2.25

=0.035*2.25

=0.07875

Hence the expected new price is

=0.07875+2.25

=$2.33

The expected increase

=2.33-2.25

=$0.08

The actual increase

=2.25-2.30

=$0.05

Hence the error is

% error= Actual -Expected/Expected*100

% error= 0.05-0.08/0.08*100

% error= 0.03/0.08*100

% error=0.375*100

% error=37.5%

Hence the error is 37.5%

Answer:

8 days

Step-by-step explanation:

90/3 = 30 mi/day

240/30 = 8 days

Answer:

it will take him 8 days (7.98 in you don't round)

Step-by-step explanation:

90 -240= 150

150/90 = 1.6666....

1.66 * 3  = 4.98

4.98+3 =7.98  (8 if you round)

Answer: 17.75 pounds

Step-by-step explanation:

After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds

Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds

Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds

The number of pounds of soil that they put in the first flower bed altogether will be:

= 6.25 + 4 + 7.5

= 17.75 pounds

Answer:

$41 is your answer

Hope it Helps :)

Answer:

$41.25

Step-by-step explanation:

If the shoes regular price was $55 and the shoes are having a sale for 25%, this is how you would do the math.

25% is 25/100 or .25

55 * .25 = $13.75

55 - 13.75 = 41.25

Answer:

88 bottles

Step-by-step explanation:

Given

[tex]Cleaner =1\ gallon[/tex]

[tex]Water =10\ gallon[/tex]

Required

Determine the number of 1-pint spray bottles used

First, we get the total gallons of the cleaner and water.

[tex]Total = Cleaner + Water[/tex]

[tex]Total = 1\ gallon + 10\ gallon[/tex]

[tex]Total = 11\ gallon[/tex]

Convert to pints:

[tex]Total = 11 * 8\ pints[/tex]

[tex]Total = 88\ pints[/tex]

To get the number of spray bottles, we divide 88 pints by the size of the pint bottle.

[tex]Number = \frac{88\ pints}{1\ pint}[/tex]

[tex]Number = \frac{88}{1}[/tex]

[tex]Number = 88[/tex]

Step-by-step explanation:

Answer:

It can not be modeled by a linear function

Step-by-step explanation:

The given parameters can be represented as:

[tex](x_1,y_1) = (1,64)[/tex]

[tex](x_2,y_2) = (2,32)[/tex]

[tex](x_3,y_3) = (3,16)[/tex]

Where: x = rounds and y = players

Required:

Determine if it can be represented by a linear function

To do this, we simply calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

and

[tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex]

Using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex], we have:

[tex]m = \frac{32 - 64}{2 - 1}[/tex]

[tex]m = \frac{-32}{ 1}[/tex]

[tex]m = -32[/tex]

Using [tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex], we have:

[tex]m = \frac{16 - 32}{3 - 2}[/tex]

[tex]m = \frac{-16}{1}[/tex]

[tex]m = -16[/tex]

Since both slopes are not the same, the relationship be modeled by a linear function

Answer:

1.we know the perimeter of the triangle=x-3+x+6+x=3x+3

so,answer is (b)3x+3

2.area of the triangle=1/2*b*h

=1/2*x+2*2x+6=x+2*2x+6/2=2x^2+6x+4x+12/2=2x^2+10x+12/2=2(x^2+5x+6)/2=x^2+5x+6

so,answer is(b)x^2+5x+6

Answer:

C

Step-by-step explanation:

Sine: Opposite / Hypotenuse

Cosine: Adjacent / Hypotenuse

Tangent: Opposite / Adjacent

75 = The adjacent of 40

H = The opposite of 40

Tan40 = 75 / h

H = 75Tan40

H ≈ 62.93

The trigonometric function which will be used to determine the height of the tree when the base is 75 ft. is tan(40)

The trigonometric function are the ratio of the sides of the right angled triangle. The functions are sine, cos, tan , cot, cosecant, secant.

We can easily see that the base is 75 ft. and the height of the tree is h So the height of the tree can be found with the help of tangent function.

tan(40)=h/75

0.84=h/75

h=63 ft.

Hence the height of the tree is 63 ft.

Answer:

a₆ = 972

Step-by-step explanation:

Is it correct?

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324

a₆ = 3a₅ = 3 × 324 = 972

Answer:

Step-by-step explanation:

Remark

You could do this two ways: one with a formula and one without. I'll do it both ways.

With Formula

a_n = 4 * 3^(n - 1)

a_6 = 4 * 3^(5)

a_6 = 4 * 243

a_6 = 972

Without

a1 = 4

a2 = 4 * 3^(2 - 1)

a2 = 4 * 3

a2 = 12

a3 = 3* a_n-1

a3 = 3 * 12

a3 = 36

a4 = 3*a_3

a4 = 3*36

a4 = 108

a5 = 3 * a_(n - 4)

a5 = 3 * 108

a5 = 324

a6 = 3 * 324

a6 = 972 which is the same answer you got by using a formula

Answer:

  see attached

Step-by-step explanation:

a) Any set of functions that has a total degree of 4 and a total number of x-intercepts of 4 will do. Shown in the first attachment are 4 linear functions. A quadratic function with two x-intercepts could replace two of the linear functions, or a cubic with 3 x-intercepts could replace 3 of the linear functions.

__

b) Again, the total degree must be 3. Since there can only be one x-intercept, the quadratic factor must have none. A possible choice is shown in the second attachment.

Answer:

1 2/3 cups of flour

Step-by-step explanation:

Nicole is cooking cookies recipe calls for 5 cups of flour she has already put in three 1/3 cups how many more cups does she need to put in?

We solve the above question using Subtraction operation

The number of cups she still needs to put in =

5 cups - 3 1/3 cups

= 5 - 3 1/3

= 5/1 - 10/3

The Lowest Common Denominator = 3

= 15 - 10/3

= 5/3

= 1 2/3 cups of flour
