Answer:

El espesor de un chip es de 0.12mm

Y el diámetro de un átomo de cobre, mide aprox:

0.00000000133 m

Queremos saber cuantos átomos deberemos alinear de tal forma que la "cadena" de átomos de cobre mida 0.12mm

Eso es equivalente a ver cuantas veces entra 0.00000000133 m en 0.12mm

Primero, escribamos ambos valores en las mismas unidades, sabiendo que:

1m = 1000mm

Podemos reescribir:

0.00000000133m = 0.00000000133*(1000 mm) = 0.00000133mm

Entonces tenemos que ver cuantas veces entra 0.00000133mm en 0.12mm

Esto sera igual al cociente entre 0.12mm y  0.00000133mm, esto es:

N = (0.12mm)/(0.00000133mm) = 90,225.6

Redondeamos al próximo número entero:

N = 90,226

Esa es la cantidad de átomos que se necesitan.

Complete this statement
nadya68 [22]

We have to complete the statement of

20ax^2+25ax+15a = 5a\left ( \   \   \   \   \  \    \right )

The left hand side is given by

20ax^2+25ax+15a

Now when we take GCF as 5a, then we have to divide each term of the expression with 5a. Thus, we have

20ax^2+25ax+15a = 5a \left (\frac{20ax^2}{5a}+\frac{25ax}{5a}+\frac{15a}{5a}   \right )\\
\\
20ax^2+25ax+15a = 5a\left ( 4x^2 +5x+3 \right )

Therefore, to complete the statement we need to enter 4x^2 +5x+3 in the box.

What is the length of a rectangle with a width of 10 cm and area of 120 cm???
melamori03 [73]

Answer:

12cm

Step-by-step explanation:

Width = 10 cm

Area = 120 cm²

Length = ?

Area = Length(L) × Width(W)

120cm²  = L × 10cm

L = 120cm² ÷ 10 cm = 12cm

Graph the equation
Lisa [10]
To find the root, replace y with 0
X^2-12x+35=0
A=1 B=-12 C=35
B^2-4ac=(-12)^2 -4(1)(35)
=144 -140
=4


x=(-b+/- square root of b^2 -4ac) /over/ (2a)
Plug in the numbers
x=-(-12) sqr (-12)^2 4(1)(35) / (2)(1)
X=12 +/-sqr 4 / 2
Positive outcome
x=12 + sqr 4 / 2
x=12+2/2
x=7 <— this one
Negative outcome
x=12-2i/2
x=6-i
Vertex: (6,-1)
