Answer:

  • y = 20
  • 4^8
  • x = 0

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a^0 = 1 . . . . for a ≠ 0

__

And, it is convenient to know the cubes of small integers:

  1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125

  6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000

__

1) p^3 × p^5 = p^-12 × p^y

Equating exponents:

  3 + 5 = -12 + y

  20 = y . . . . . . . . . . . add 12

__

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

__

3) 10^x = 1 = 10^0

  x = 0

Una torre de 28.2 m de altura esta situada a la orilla de un rio, desde lo alto del edificio el ángulo de depresión a la orilla
Svet_ta [14]

Answer:

El ancho del río es 59.9 metros.

Step-by-step explanation:

El ancho del río lo podemos calcular con la siguiente relación trigonométrica asumiendo que la torre forma un triángulo rectángulo con el río:

tan(\theta) = \frac{CO}{CA}

En donde:

CA: es el cateto adyacente = Altura de la torre = 28.2 m

CO: es el cateto opuesto = ancho del río =?

θ: es el ángulo adyacente a CA

Dado que el ángulo de depresión (25.2°) está ubicado fuera de la parte superior de la hipotenusa del triángulo que forma la torre con la orilla opuesta del río, debemos calcular el ángulo interno (θ) como sigue:

\theta = (90 - 25.2)^{\circ} = 64.8 ^{\circ}

Ahora, el ancho del río es:

CO = tan(\alpha)*CA = tan(64.8)*28.2 = 59.9 m

Por lo tanto, el ancho del río es 59.9 metros.

Espero que te sea de utilidad!

18 bracelets in 3 hours
g100num [7]

Answer:

= 6 items per hour

Explanation:

This is a fraction equal to 18 items ÷ 3 hours

We want a unit rate where 1 is in the denominator, so we divide top and bottom by 3

18 items ÷ 3

3 hours ÷ 3

= 6 items/1 hour

= 6 items/hour

= 6 items per hour
