Answer:

BE = 22.4 cm

Step-by-step explanation:

Δ CAB and Δ CDE are similar , then ratios of corresponding sides are equal, that is

$\frac{CB}{CE}$ = $\frac{AB}{DE}$ , substitute values

$\frac{6.4}{CE}$ = $\frac{8}{20}$ ( cross- multiply )

8 CE = 128 ( divide both sides by 8 )

CE = 16 cm

Then

BE = BC + CE = 6.4 + 16 = 22.4 cm

Answer:

1/8 or 0.125

Step-by-step explanation:

Let x be the length of the sides of the square ABCD.

Therefore, the length of CN and CM is x/2.

The area of the triangle MCN is:

$A_t = \frac{0.5x*0.5x}{2}=\frac{x^2}{8}$

The area of the square ABCD is:

$A_s =x*x =x^2$

Thus, the probability that a random point lies in the triangle MCN is:

$P=\frac{A_t}{A_s}=\frac{\frac{x^2}{8}}{x^2}=\frac{1}{8}=0.125$

The probability that the point will lie in the triangle MCN is 1/8 or 0.125.

What is the multiplication and division property of exponets?

Alexandra [31]

Mult
$(x^m)(x^n)=x^{m+n}$

div
$\frac{x^m}{x^n} =x^{m-n}$

baseically, x is the base, and m and n are bases

you can only use this property if bases are same

baseically
multiply means add powers
divide means subtract bottom power from top
