Which expression is equivalent to 3 sqrt 27x^18

shusha [124]

Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).

We split up the radicand into perfect squares. Once we do, we take out the things that were squared:
$3\sqrt{27x^{18}} = 3\sqrt{3\times3\times3x^2x^2x^2x^2x^2x^2x^2x^2x^2x^2} = 3*3*xxxxxxxxx\sqrt{3}
$
$=9x^9\sqrt{3}$

Given line LM and point R that lies on line LM, identify the following ratios given that point R lies a/b of the way along line

gavmur [86]

Answer:

See explanation

Step-by-step explanation:

If point R lies $\frac{a}{b}$ of the way along line LM, closer to L than M, then

$LR=ax\\ \\LM=bx$

Find all needed ratios:

1. $\dfrac{LR}{LM}=\dfrac{ax}{bx}=\dfrac{a}{b}$

2. By segment addition postulate,

$LR+RM=LM\\ \\RM=bx-ax=(b-a)x,$

$\dfrac{RM}{LM}=\dfrac{(b-a)x}{ax}=\dfrac{b-a}{a}$

3. $RL=LR=ax\\ \\RM=(b-a)x,$

then

$\dfrac{RL}{RM}=\dfrac{ax}{(b-a)x}=\dfrac{a}{b-a}$

In Wellington, a city of 360,000 citizens, there has been an outbreak of vampires and werewolves There are 3,000 people infected

Alex17521 [72]

Answer:

0.0286 or 2.86%

Step-by-step explanation:

The total number of people that have werewolfism is 21,000.

Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

$P(V|W)=\frac{N_{V\cap W}}{N_W}\\P(V|W)=\frac{600}{21,000} \\P(V|W)=0.0286=2.86\%$

The probability is 0.0286 or 2.86%.

A rectangular container that measures 2 cm x 11 cm x 20 cm is completely filled with water. The water is then poured into a holl

maksim [4K]

Answer:

14cm

Step-by-step explanation:

formula of a rectangular container is LBH and we were given that LBH is 2*11*20 which is equal to 440cm.

Now when the water is transferred into a hollow cylindrical container.the formula for that is 2pierh.440=2*22/7*5*h

440*7=220h

3080=220h

h=14cm
