For this case we have the MNP triangle whose sides measure:

$L1: 3.5cm\\L2: 4.1cm\\L3: 4.3cm$

If we want to find a similar triangle, it must have a scale factor "x" on each side with respect to the MNP triangle. So:

$L1 ':( x) 3.5cm\\L2 ':( x) 4.1cm\\L3 ':( x) 4.3cm$

If $x = 10$ we get:

$L1 ': 35cm\\L2 ': 41cm\\L3 ': 43cm$

Answer:

x^2 = 121

Step-by-step explanation:

Sea el ancho del terreno x metros

Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x

Matemáticamente, el área de un rectángulo es;

Anchura longitud Por lo tanto, tenemos

x * 2x = 242 metros cuadrados

Así; 2x ^ 2 = 242

x ^ 2 = 242/2

x ^ 2 = 121

Calculate the mean of the following data 2,3,5,6,1,10

defon

the mean is adding all them together and dividing by how many there are

2+3+5+6+1+10 = 27

there are 6 numbers so 27/6 = 4.5

mean = 4.5

A box has a volume of 546cm3 and a surface area of 422cm2. What are the Length, Width and Height?

Klio2033 [76]

We know that the formula for the volume of a box is:

$V =lwh$

Where:
l = length
w = width
h = height

The formula of the surface area of a box is:
$SA=2(lw+lh+wh)$

Based on the given we know the following:
$546cm^{3} =lwh$

and

$422cm^{2}=2(lw+lh+wh)$

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

$546=6*7*13$

Let:
l = 6cm
w = 7cm
h = 13cm

Now let's try this on the surface area formula:
$422cm^{2}=2(lw+lh+wh)$
$422cm^{2}=2((6cm*7cm)+(6cm*13cm)+(7cm*13cm))$
$422cm^{2}=2(42cm^{2}+79cm^{2}+91cm^{2})$
$422cm^{2}=2(211cm^{2})$
$422cm^{2}=422cm^{2}$

The answer is then:
l = 6cm
w = 7cm
h = 13cm

Any order would be fine.
