If A represents a vector two units in length directed due west, B represents a vector three units in length directed due north a
Ludmilka [50]

Answer:

Step-by-step explanation:

Given

Vector A has two units in length due to west i.e.

\vec{A}=-2\hat{i}

Vector B has one unit in length due to North i.e.

\vec{B}=\hat{j}

Also A+B=C-D

i.e. C-D=-2\hat{i}+\hat{j}--------1

also 2B-A=C+D

i.e. C+D=2\times \hat{j}+2\hat{i}------2

From 1 and 2

2C=3\hat{j}

C=1.5\hat{j}

D=2\hat{i}+0.5\hat{j}

En un acuario compraron 30 peces y 18 tortugas de agua. Los van a colocar en peceras. Cada una tiene que haber la misma cantidad
seraphim [82]

Answer:

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

3 peces por tanque

5 tortugas de agua por tanque

Step-by-step explanation:

Resolvemos la pregunta anterior utilizando el cálculo de múltiplo común más bajo

En un acuario compraron 30 peces y 18 tortugas de agua.

Encuentre y enumere los múltiplos de cada número hasta encontrar el primer múltiplo común. Este es el mínimo común múltiplo.

El mínimo común múltiplo es el número de tanques

Múltiplos de 18:

18, 36, 54, 72, 90, 108, 126

Múltiplos de 30:

30, 60, 90, 120, 150

Por lo tanto,

MCM (18; 30) = 90

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

El número de peces que puede tener cada tanque = Número de tanques / Número de peces

= 90/30

= 3 peces por tanque

El número de tortugas de agua que puede tener cada tanque =

Número de tanques / Número de tortugas de agua

= 90/18

= 5 tortugas de agua por tanque
