Sam invests $800 at 6%/a compounded annually for 5 years. What is the total interest<br> earned?

s2008m [1.1K]

<h3>Answer: 270.58 dollars</h3>

======================================================

Work Shown:

A = account value after t years
P = principal or amount deposited = 800
r = interest rate in decimal form = 0.06
n = number of times we compound per year = 1
t = number of years = 5

So,

A = P*(1+r/n)^(n*t)

A = 800*(1+0.06/1)^(1*5)

A = 1070.58046208

A = 1070.58

After five years, the account will have $1,070.58 in it.

The amount of interest earned is A-P = 1070.58 - 800 = 270.58 dollars.

La montaña más alta del mundo es Everest cuya altura es de 8.848m y la altura de la segunda montaña más alta es de 2hm 3dam y 7m

olchik [2.2K]

Answer:

La segunda montaña más alta del mundo tiene 8611 metros.

Step-by-step explanation:

La montaña más alta del mundo es Everest cuya altura es de 8.848m.

La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que

1 hm= 100 m
1 dam= 10 m

Entonces podes aplicar las siguientes reglas de tres simple:

Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?

$metros=\frac{2 hm*100 m}{1 hm}$

metros= 200

Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?

$metros=\frac{3 dam*10 m}{1 dam}$

metros= 30

Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:

8848 metros - 237 metros= 8611 metros

<u><em>La segunda montaña más alta del mundo tiene 8611 metros.</em></u>
