Answer:

$8.75

Step-by-step explanation:

Divide $43.75 by 5 to get the cost of ONE movie ticket like so:

$43.75 / 5 movie tickets = $8.75 per ticket.

Therefore, ONE ticket costs $8.75.

Answer:

y = 100° , x = 80°

Step-by-step explanation:

Two angles on a straight line equal 180°. Therefore, 80° + y = 180°. This means y = 100°.

80° and x are alternate exterior angles. Using that property, we know those angles are congruent. This means x is also 80°.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So first you have to plug in what you know...

[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]

If it's hard to look at it that way you should make it look like this...

[tex]2\frac{1}{4} >3[/tex]

Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.

Answer:

  B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles

Step-by-step explanation:

The mileage charge for x miles will be $0.55x, so the total charge will be $1.45+$0.55x. This must be less than or equal to $35 for Ariel to be able to pay for her travel. The appropriate inequality is ...

  $1.45 +$0.55x ≤ $35 . . . . . matches choice B

__

Comment on selecting an answer

From a "reasonableness" point of view, any answer choice with "≥ $35" can be eliminated immediately. Further, any answer choice with $1.45x can be eliminated, since the mileage charge is not $1.45, it is $0.55. The leaves only the choice shown above.

Answer:

En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.

Step-by-step explanation:

La cantidad de cajas es igual a la cantidad de memorias dividida por la capacidad de una caja. Al indicarse que las memorias serán guardadas en cajas de igual capacidad, sin mezclar los colores y con el mayor número posible de artículos, podemos utilizar el concepto de máximo común divisor, cuyo procedimiento mostramos a continuación:

(i) Realizamos la descomposición factorial de cada número:

Memorias rojas:

[tex]84 = 2\times 2 \times 3\times 7[/tex]

Memorias azules:

[tex]196 = 2\times 2\times 7\times 7[/tex]

Memorias verdes:

[tex]252 = 2\times 2\times 3 \times 3 \times 7[/tex]

(ii) Hallamos los números primos en común que tiene cada colección de memorias:

[tex]S=\{2,2,7\}[/tex]

(iii) Calculamos el máximo común divisor al multiplicar los elementos del conjunto S:

[tex]M.C.D. = 2\times 2\times 7[/tex]

[tex]M.C.D. = 28[/tex]

Esto quiere decir que cada caja debe llevar 28 memorias del mismo color. Finalmente, calculamos la cantidad requerida de cajas para cada memoria.

Memorias rojas:

[tex]n_{R} = \frac{84}{28}[/tex]

[tex]n_{R}= 3[/tex]

Memorias azules:

[tex]n_{A} = \frac{196}{28}[/tex]

[tex]n_{A} = 7[/tex]

Memorias verdes:

[tex]n_{V} = \frac{252}{28}[/tex]

[tex]n_{V} = 9[/tex]

En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.

Answer:

my guess is irrational

Step-by-step explanation:

A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).

Answer:

  translate <-6, 0>, reflect over x

Step-by-step explanation:

Point D is at the top in the pre-image and at the bottom in the image, so a vertical reflection is indicated. Only the 1st and 3rd choices show a reflection over the x-axis.

The image is to the left of the pre-image by 6 units, so the translation is in the negative direction. Only the 3rd choice has that.

Step-by-step explanation:

A. For Tavon's gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=145-3.5x------1

for Tavon's second gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=125-3x-------------2

B. equating 1 and 2 we have

145-3.5x=125-3x

solve for x we have

145-125=-3x+3.5x

20=0.5x

divide both sides by x we have

x=20/0.5

x= 40

put x=40 in

y=145-3.5*40------1

y=145-140

y=$5

put x=40 in

y=125-3*40------1

y=125-120

y=$5

Answer:

32 degrees

Step-by-step explanation:

90 + 58 = 148

180 - 148 = 32

Answer:

C.

Step-by-step explanation:

(-90) + (-20) + 100 = -10

Hope I Helped! :)

Answer:

The solution is C. -10

Step-by-step explanation:

Before entering the solution, remember the formula first!

Addition

• (-) + (-) = (-)

• (+) + (+) = (+)

Subtraction

• (+) - (+) = can (-) and (+)

• (+) - (-) = (+)

Multiplication

• (-) x (-) = (+)

• (+) x (-) = (-)

Division

• (-) : (-) = (+)

• (+) : (-) = (-)

Solution:

(-90) + (-20) + 100

= -90 - 20 + 100

= -110 + 100

= -10 (the minus number is greater than the positive, then the result is minus)

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8)  are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

Answer:

Step-by-step explanation:

The function has a positive leading coefficient (1/3) and is of odd degree (3). These conditions mean the sign of the end behavior of the function will match the sign of x.

  x → ∞, m(x) → ∞

  x → -∞, m(x) → -∞
