Simplify ^3 V-27n^27

Sauron [17]

Apply the radical rule to separate terms:

Cubicroot(-27) and cubic root(n^27)

Cubicroot(-27) = -3

Now you have -3 cubicroot(n^27)

Using the exponent rule

N^27 can be rewritten as (n^9)^3

Now you have -3 cubicroot((n^9)^3)

The cubic root and the 3rd power cancel out to get the final answer of

-3n^9

Imaginen que un maratonista corre toda una carrera a una velocidad constante. Después de dos horas lleva recorridos 22 km

saw5 [17]

For this case we have:

If after 2 hours the marathon runner has traveled 22 kilometers we have:

2h -----------> 22km

Applying a rule of three, we can know the time it takes to run 42km. So, we have:

2h -----------> 22km

x -------------> 42km

Where "x" is the time it takes to travel 42km. Resolving we have:

$x = \frac {(42 * 2)} {22}$

$x = \frac {84} {22}$

$x = \frac {42} {11}$

$x = 3.82 hours$

Thus, after 3.82 hours the marathon runner will travel 42km.

Answer:

3.82 hours

vovikov84 [41]

Answer:

C)2 : 1

Step-by-step explanation:

AEFG ≈ ALMN

FG / MN = 4 / 2 = 2/1

So the ratio of AEFG to ALMN = 2 / 1 or 2 : 1
