Un microempresario realiza una inversión donde le pagan una rentabilidad del 5,36% mensual simple, él desea que esa inversión se
yarga [219]

Answer:

Deberá esperar 37.31 años para que esto ocurra.

Step-by-step explanation:

Este es un problema de interés simple.

La fórmula del interés simple viene dada por:

E = P*I*t

En el que E es la cantidad de interés ganado, P es el principal (la cantidad inicial de dinero), I es la tasa de interés (anual, como decimal) y t es el tiempo.

Después de t años, la cantidad total de dinero es:

T = E + P

5,36% mensual simple

Esto implica que I = 0.0536

Inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?

Tiempo t para que la cantidad de interés sea lo doble de la cantidad inicial, o sea, E = 2P.

E = P*I*t

2P = P*I*t

It = 2

0.0536t = 2

t = \frac{2}{0.0536}

t = 37.31

Deberá esperar 37.31 años para que esto ocurra.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inc
Bond [772]

The relationship is that two times the volume of cylinder is volume of cone

<em><u>Solution:</u></em>

Given that, cylinder and a cone have the same diameter: 8 inches

Diameter = 8 inches

Radius is diameter divided by 2

radius = \frac{diameter}{2}\\\\radius = \frac{8}{2} = 4

Radius = 4 inches

<u><em>Let us find the volume of cylinder and cone</em></u>

<u><em>Volume of cylinder:</em></u>

volume = \pi r^2 h

Radius = 4 inches

The height of the cylinder is 3 inches

height = 3 inches

Substituting the values, we get

volume = 3.14 \times 4^2 \times 3\\\\volume = 3.14 \times 16 \times 3\\\\volume = 150.72

Thus volume of cylinder is 150.72 cubic inches

<em><u>Volume of cone:</u></em>

volume = \frac{\pi r^2h}{3}

Radius = 4 inches

The height of the cone is 18 inches

height = 18 inches

Substituting the values, we get

volume = \frac{3.14 \times 4^2 \times 18}{3}\\\\volume = 3.14 \times 16 \times 6\\\\volume = 301.44

Thus volume of cone is 301.44 cubic inches

<em><u>What is the relationship between the volume of this cylinder and this cone?</u></em>

Volume of cylinder is 150.72 cubic inches

Volume of cone is 301.44 cubic inches

On observing the volume of cylinder and cone, we find that two times the volume of cylinder is volume of cone

2 \times \text{Volume of cylinder} = \text{Volume of cone}

2 \times 150.72 = 301.44\\\\301.44 = 301.44

Thus the relationship between the volume of this cylinder and this cone is that two times the volume of cylinder is volume of cone
