Sally went to the video game store and bought 2 used video games for $22.50 each, one new game for $55, and a gaming magazine for $12.95. There was 6.5% tax on the purchase. What was the total purchase price after tax?

Answer: 28

Step-by-step explanation: Mean will be the average of all your numbers divided by the amount of numbers you have. So

24+24+12+52=112

Now since you have 4 numbers divide 112 by 4

So your mean is 28

Answer:

Step-by-step explanation:

Answer:

Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Step-by-step explanation:

Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:

[tex]0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}}[/tex] (1)

Donde:

[tex]m_{A}[/tex] - Masa de la solución al 20 %, en onzas.

[tex]m_{B}[/tex] - Masa de la solución al 40 %, en onzas.

Podemos simplificar la formula como sigue:

[tex]0.2\cdot x + 0.4\cdot (1-x) = 0.34[/tex] (2)

Donde [tex]x[/tex] es la proporción de la solución al 20 % dentro de la solución final, sin unidades.

Ahora resolvemos para [tex]x[/tex] en (2):

[tex]0.4-0.2\cdot x = 0.34[/tex]

[tex]0.2\cdot x = 0.06[/tex]

[tex]x = \frac{0.06}{0.2}[/tex]

[tex]x = 0.3[/tex]

Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Answer:

C: 95.9%

Step-by-step explanation:

To find this, we shall be using the cumulative binomial probability calculator

As we know, the probability of getting a head or a tail in a throw of a coin is same with a value of 0.5

So, we want to find the probability of getting tails 50 times or fewer which means the probability of getting at most 50 tails

So we have the parameters as follows;

P( x ≤ 50)

n = number of trials = 85

p = probability of success = 0.5

r = number of success = 50

Using the parameters in the cumulative binomial probability calculator, we have the value as ;

0.9589 = 95.9%

Melanie is correct

85 x 0.35 = 29.75

85 - 29.75 = 55.25

Answer:

a. Melanie is correct

Step-by-step explanation:

35% of 85= 29.75

*Find this by finding 10% (move decimal place over) and five percent (half of ten percent) and add triple of 10% plus the 5% or look it up*

Subtract this from 85

85-29.75=

Answer:

tgα = 9/8

secα = 10/8

cscα = 10/9

ctgα = 8/9

Step-by-step explanation:

PAra resolver esto, es necesario conocer como se determinan las funciones trigonométricas en general. Ya tenemos el valor del seno y coseno de un angulo dado (supongamos un angulo α)

Si senα = 9/10 y cosα = 8/10, para calcular la tangente se aplica la siguiente expresión:

tgα = senα / cosα  (1)

Reemplazando tenemos:

tgα = (9/10) / (8/10)        Aqui se simplifican los 10, y nos queda

Nos quedan 3 funciones, y son las inversas de estas 3 funciones anteriores, y se determinan de la siguiente forma:

secα = 1 / cosα   (2)

cscα = 1 / senα   (3)

ctgα = 1 / tgα = cscα / secα  (4)

Aplicando estas 3 expresiones tenemos:

secα = 1 / (8/10)           Se aplica inversión de numerador y denominador

cscα = 1 / (9/10)

ctgα = 1 / (9/8)

Answer:

A. - 2

Step-by-step explanation:

Given

2/3 ( 6 - 9x) = 16

or, 6 - 9x = 16 * 3 / 2

or, 6 - 9x = 24

or, - 9x = 24 - 6

- 9x = 18

x = 18 / - 9

Therefore x = - 2

Answer:

Option 1:  V = pi(6)2(8)

Step-by-step explanation:  

This is because when we plug in the value given in the picture.  

Formula  

The way we write this is by using our  "r" which is 6. We plug in the 6 for "r" so the equation will look something like this:  

Then we will plug in our height "h", which is 8. So the equation will look something like this:  

So that's it. Very simple. Just remember to keep the formula in mind and you will get the hang of it.  

I hope this help! :D

Equation to calculate volume of solid is V = 6 × 8 × 7

An equation is a formula that expresses equality by connecting two expressions with an equal sign =. Equation consists of variables, constants and coefficients. Right side and left side of an equation are in equality.

There are different types of equations as linear equations, quadratic equation etc.

example: 2x + 5y + 7 = 0 is an equation

here, 2, 5 are coefficients of variables x and y, 7 is a constant value

2x² + 5x + 3 = 0 is a quadratic equation.

Given,

measurement of the sides of solid

length = 6in

Width = 8 in

Height = 7 in

Volume = Length×Width×Height

V = 6 × 8 × 7

Volume = 336 in³

Hence, V = 6 × 8 × 7 is the equation to calculate volume of solid.

Answer:

The coordinate of the midpoint of AB is (1.5, 3).

Step-by-step explanation:

The midpoint of AB is the point that is the same distance between both points A and B. In order to find the midpoint, add the x and y values of points A and B respectively, and divide the sum by 2 to find the midpoint of AB. [tex]\frac{1+2}{2} = 1.5[/tex], so the x value of the midpoint is 1.5. [tex]\frac{0+6}{2} = 3[/tex], so the y value of the midpoint is 3. You'll get that the coordinate of the midpoint of AB is (1.5, 3).

Answer:

3,-2

Step-by-step explanation:

From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,

Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.

Slope :-

→ m = 3 - 0 / 0 - 1.5

→ m = 3/-1.5

→ m = -2

Step-by-step explanation:

The geometric mean of two numbers 14 and 6 is 2√21.

An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.

In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.

Given, Two numbers 14 and 6.

Now, 14×6 = 84.

Now, we have to take the square root of 84 as we have two numbers.

Therefore, The geometric mean of 14 and 6 is,

= √(84).

= 2√21.
