b. Miguel tiene 104 canicas grandes, 117
medianas y 130 pequeñas. Si quiere
repartirlas en grupos iguales con la
mayor cantidad de cada tipo de cani-
cas, ¿cuántos grupos podrá formar?
¿Cuántas canicas de cada tipo habrá
en cada grupo?

Answers

Considerando la definición de divisor común mayor:

si Miguel quiere repartir las canicas en grupos iguales con la mayor cantidad de cada tipo tendrá 13 grupos.en cada grupo habrá 8 canicas grandes, 9 canicas medianas y 10 canicas pequeñas.

Definición de divisor

Los divisores de un número natural son los números naturales que lo pueden dividir, resultando de cociente otro número natural y de resto 0. Ser divisor es lo recíproco a ser múltiplo.

En otras palabras, un número es divisor de otro si está contenido una cantidad entera de veces. Por lo tanto, al dividir el número por el divisor el cociente debe resultar un número entero (que no sea un número decimal) y el residuo o resto de la división sea 0.

Divisor común mayor

Se denomina máximo común divisor al mayor número que divide exactamente a dos o más números a la vez.

En otras palabras, el divisor común mayor es el mayor de los divisores que tienen en común dos o más números.

Para calcular el divisor común mayor se debe realizar los siguientes pasos:

Descomponer cada número en factores primos.Después, señalar los factores comunes (números primos que aparecen en todos los números).A continuación, en cada uno de los comunes, escoger el factor con menor exponente (factor que aparece la menor cantidad de veces).Por ultimo, multiplicar los factores elegidos.

Cantidad de grupos

Para calcular la cantidad de grupos se debe calcular el divisor común mayor. Para ello, en primer lugar se descomponen los números:

104= 2×2×2×13= 2³×13117= 3×3×13= 3²×13130= 2×5×13

El factor común a todos los números es el número 13. Esto indica que si Miguel quiere repartir las canicas en grupos iguales con la mayor cantidad de cada tipo tendrá 13 grupos.

Cantidad de canicas de cada tipo en cada grupo

Para esto se deberá dividir la cantidad de cada tipo de canica por la cantidad de grupos formados, que en este caso es 13. Esto es:

104 canicas grandes÷ 13 grupos= 8 canicas grandes117 canicas medianas÷ 13 grupos= 9 canicas medianas130 canicas pequeñas÷ 13 grupos= 10 canicas pequeñas

Finalmente, en cada grupo habrá 8 canicas grandes, 9 canicas medianas y 10 canicas pequeñas.

What is the solution to this equation?
-1/5(x+1 1/4)=-2 1/2

Answers

Answer:

О  x = 10 3/4

[tex]x = 10\frac{3}{4}[/tex]

Step-by-step explanation:

-1/5 ( x + 1 3/4) = -2 1/2

Particularly:

1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4

-2 1/2 = -2 - 1/2 = -4/2 - 1/2 = -5/2

Then:

-1/5 (x + 7/4) = -5/2

(x*-1/5 + 7/4*-1/5) = -5/2

(-x/5 + ((7*-1) / (4*5))) = -5/2

-x/5 + (-7/20) = -5/2

-x/5 - 7/20 = -5/2

-4x/20 - 7/20 = -50/20

-4x - 7 = -50

-4x =  -50  + 7

-4x = -43

x = -43/-4

x = 43/4

43/4 = 40/4 + 3/4 = 10 + 3/4 = 10 3/4

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount invested at 13% and y represent the amount invested at 12%, hence:

Answer: constant of proportionality = 0.75

How to find constant of proportionality?

Constant of proportionality is the same as the slope of a straight line.

Slope formula is given by:

[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]

Here take two points: (0, 0), (4, 3)

[tex]So, \sf \ slope : \dfrac{3-0}{4-0} = \dfrac{3}{4} \quad or \quad 0.75[/tex]

Hence, the constant of proportionality is 0.75

Answer:

Constant of proportionality = 0.75

Step-by-step explanation:

To find the constant of proportionality of a graph that goes through the origin:

• First select a point on the graph whose coordinates you can easily read; in this case such a point is already marked (4, 3).

• Next, simply divide the y-value by the x-value of the coordinates to find the constant of proportionality:

Constant of proportionality = y ÷ x

                                              3 ÷ 4

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Energy Drinks: Popular energy drinks contain green tea extract and caffeine. Do these energy drinks help you lose weight by increasing your metabolism? Researchers at a medical school designed an experiment to determine the chemical effects of green tea and caffeine on energy metabolism in healthy, lean, young adults. Researchers randomly assigned participants to 2 treatments. One group drank Formula A, a beverage with green tea and caffeine. The other group drank Formula B, a beverage with none of these ingredients but colored to look like Formula A. The beverages were blinded at the production site, so the experiment was double-blind. The researchers chilled the beverages to 6°C. Participants drank the beverages at the same time each day for three days. During the 3 days of the experiment, the researchers fed each participant the same diet. On the 3rd day participants spent 24 hours in a calorimeter chamber to measure their energy metabolism. The medical journal Obesity published the results in 2007. Which confounding variable is controlled by randomly assigning individuals to treatments? the effect of green tea and caffeine on energy metabolism the effect of green tea and caffeine on energy metabolism the physical fitness level of the participants the physical fitness level of the participants the time of day participants drank the beverages the time of day participants drank the beverages

A confounding variable is also referred to as a confounder and it can be defined as a type of variable that has the ability to influence both the independent and dependent variables.

Also, a confounding variable is usually not accounted for by the researcher and as such it can cause a spurious association between the independent and dependent variables.

front of the house? Do not include units in your answer.

Answers

Answer:

108

Step-by-step explanation:

if the width of the rectangle is 8, and the triangle is on the width of the rectangle, then the base of the rectangle is 8. the height is 7, so we use the formula area = height * base / 2 to find that the area of the triangular portion is 28. then, we find the area of the rectangle by doing 10 * 8(height * width) for a value of 80. the total area of the front of the house is 28 + 80: 108.

Will give brainliest and about 50-100 points if done right! The figure below shows a ball on a curved surface. The ball is released at point A. At which point does the ball have maximum gravitational potential energy? Suppose the elasticity of demand for cereal is 1. If cereal increases in price by 25 percent, the percentage decrease in quantity demanded will be A group of researchers carried out a study to determine which type of portable water purification system is the most effective. Throughout the study, they used water from a variety of lakes in the region. Which conclusion could be reported based on this study
