Answer:

Answer is C.

Step-by-step explanation:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

#1.) A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.

I don't want to give you the answer cause that will not help you I'm the future If I just give it to you. It might help you but that's what I learned in school is that it doesn't help. Because like if you cheat on a test you won't get to learn. But if you did it yourself and got it wrong you can see why

What is rounding for math

Sedaia [141]

Answer:

Step-by-step explanation:

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.

En una caja de cartón se empacan 400 latas de atún al acomodarlas resultan que caben 5 latas más a lo largo que a lo ancho y a l

Anvisha [2.4K]

Answer:

Hay 50 latas en total que tocan el fondo de la caja.

Step-by-step explanation:

Una caja de cartón es representada por un cuadrilátero, cuyas caras son rectángulos. Si la caja esta ocupada por completo, entonces la cantidad total de latas es representada por la siguiente expresión:

$n_{V} = n_{w}\cdot n_{h}\cdot n_{l}$ (1)

Donde:

$n_{V}$ - Total de latas de atún, adimensional.

$n_{w}$ - Cantidad de latas de atún a lo ancho de la caja, adimensional.

$n_{h}$ - Cantidad de latas de atún a lo alto de la caja, adimensional.

$n_{l}$ - Cantidad de latas de atún a lo largo de la caja, adimensional.

De acuerdo con el enunciado, tenemos las siguientes relaciones:

$n_{V} = 400$ (2)

$n_{l} = n_{w} +5$ (3)

$n_{h} = n_{w}+3$ (4)

Si aplicamos estas fórmulas a (1), tenemos el siguiente polinomio de tercer orden:

$n_{w} \cdot (n_{w}+5)\cdot (n_{w}+3) = 400$

$n_{w}\cdot (n_{w}^{2}+8\cdot n_{w}+15) = 400$

$n_{w}^{3}+8\cdot n_{w}^{2}+15\cdot n_{w} -400 = 0$

Este polinomio se puede resolver por vía analítica por el Método de Cardano o por vía numérica, sus raíces son:

$n_{w,1} = 5$ , $n_{w,2} = -6.5+i\,6.144$ , $n_{w,3} = -6.5-i\,6.144$

En consecuencia, la única solución válida es $n_{w} = 5$ y las variables restantes son por (3) y (4):

$n_{l} = 10$ y $n_{h} = 8$

La cantidad de latas que tocan el fondo de la caja es igual al producto de la cantidad de latas a lo largo de la caja y la cantidad de latas a lo ancho de la caja, es decir:

$n_{A} = n_{w}\cdot n_{l}$ (5)
