The digits of a two-digit number sum to 8. When the digits are reversed the resulting number is 18 less than the onginal
polet [3.4K]

Answer:

53

Step-by-step explanation:

Given: The sum of two digit number is 8

           Reversing the digit will get us number 18 less than the original.

Lets take x as tenth digit of our number and y as unit digit of our number.

As given sum of digit is 8

∴ x+y= 8

∴ y= 8-x -       equation 1

We also know that reversing the digit will get us number 18 less than the original.

∴ 10y+x = 10x +y-18

Now, lets put the value of y from equation 1

⇒ 10(8-x) + x = 10x+ (8-x)- 18

⇒ 80-9x= 9x-10

⇒ 90= 18x

∴ x= 5

Next, substituting the value of x in equation 1

y= 8-x

⇒ y= 8-5 = 3

∴ y= 3

∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.

Alisa, Mykia, and Martin decide to share the responsibility of walking their dog every day. There are 365 days in a year. How ma
shutvik [7]

Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Note that 24 hours = 1 day

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!
