Answer:

A) En 19 paquetes habrá 152 velitas.

B) Se podrían armar 40 paquetes iguales con 320 velitas.

Step-by-step explanation:

La regla de tres simple directa consiste en una relación de cantidades con proporcionalidad directa, que se da cuando dadas dos cantidades correspondientes son magnitudes directamente proporcionales. Esto es, si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número.

La regla de tres simple permite hallar un cuarto término de una proporción conociendo los otros tres.

Siendo a, b y c datos conocidos y x la incógnita, la regla de tres simple se aplica de la siguiente manera:

a ⇒ b

c ⇒ x

Entonces: x=\frac{c*b}{a}

A) En este caso la regla de tres simple se aplica de la siguiente manera: si en 3 paquetes hay 24 velitas, en 19 paquetes ¿Cuántas velitas habrá?

3 paquetes → 24 velitas

19 paquetes → x

Entonces x=\frac{19 paquetes*24 velitas}{3 paquetes}

x= 152 velitas

<u><em>En 19 paquetes habrá 152 velitas.</em></u>

B) En este caso la regla de tres simple se aplica de la siguiente manera: si hay 24 velitas en 3 paquetes, hay 320 velitas ¿Cuántos paquetes se podrán armar?

24 velitas → 3 paquetes

320 velitas → x

Entonces x=\frac{320 velitas*3 paquetes}{24 velitas}

x= 40 paquetes

<u><em>Se podrían armar 40 paquetes iguales con 320 velitas.</em></u>

Answer:

[See Below]

Step-by-step explanation:

❶ It is irrational because to make it repeating it must be <u>EXACT</u>. In this case it is adding a 0 after every 1. So it'd be irrational since it doesn't have an end.

❷ Irrational because no one knows the end of pi. It doesn't have an ending so therefore irrational.

A x 4 = E
lana [24]
A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4

A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===

If f(x) = 2x – 5 and g(x) = x +4, then f(g(2)) =
dolphi86 [110]

Answer:

7

Step-by-step explanation:

f(g(2))

f(x+4) and you would replace x with two, so you would get

f(2+4) = f(6)

You would then plug in 6 for the x in the f(x) equation:

2(6) - 5 = 12-5 = 7
