The perimeter of a rectangle is 1144 ft. It’s length is three times it’s width.find the dimensions of the rectangle.

AVprozaik [17]

Answer:

$Length= 429 feet\\Width=143feet$

Step-by-step explanation:

Perimeter of the rectangle= 1144 feet

Length=3*Width

L=3*W

Perimeter of rectangle:

$2(Length+Width)\\\\ 1144=2(3W+W)\\\\ 1144/2=3W+W\\\\ 572=4W\\\\ W=572/4\\\\ W= 143 feet\\\\Width=143 feet\\\\Length=3*143=429 feet\\\\$

The Dimension of the rectangle is :

$Length= 429 feet\\Width=143feet$

I need to calculate X<br><br> 2^x=200<br><br> Solve for x

antoniya [11.8K]

Remember
$log(a^z)=zlog(a)$
so

notice that 200=2*2*2*5*5, so x cannot be a whole number

take the log base 10 of both sides

$log_{10}(2^x)=log{10}(200)$
$xlog_{10}(2)=log{10}(200)$
divide both sides by $log_{10}(2)$
$x= \frac{log_{10}(200)}{log_{10}(2)}$

if we used $log_{2}$ instead of $log_{10}$ we would get
$x= log_{2}(200)$ because $log_{a}(a^b)=b$

¿Qué interés produce s/ 72,000 al 5% anual en 1 año, 1 mes, 10 días?

PtichkaEL [24]

Answer: 3,988.8

Usaremos la fómula: I = C * i * n

I = 72 000 * 0.05 * (1 año + 1 mes + 10 día)

I = 72 000 * 0.05 * (1 + 0.08 + 0.0028)

I = 72 000 * 0.05 * 1.108

3,988.8

Step-by-step explanation:

Podemos obtener el interés que produce un capital con la siguiente fórmula:

I = C * i * n

Ejemplo: Si queremos calcular el interés simple que produce un capital de 1.000.000 pesos invertido durante 5 años a una tasa del 8% anual. El interés simple se calculará de la siguiente forma:

I = 1.000.000 * 0,08 * 5 = 400.000

Si queremos calcular el mismo interés durante un periodo menor a un año (60 días), se calculará de la siguiente forma:

Periodo: 60 días = 60/360 = 0,16

I = 1.000.000 * 0,08 * 60/360 = 13.333

Espero te ayude :3
