10 gallons blue to 18 gallons red.
to find the answer, multiply/divide both 5 and 9 by the same number. In this case, I multiplied them both by two. 5×2=10, 9×2=18.

Write (1/3i)-(-6+2/3i) as a complex number in standard form

Eddi Din [679]

Answer:

$6+\frac{i}{3}$

Step-by-step explanation:

$\frac{1}{3\imath}-(-6+\frac{2}{3\imath})$

$\frac{1}{3\imath}+6-\frac{2}{3\imath}$

taking like terms together

$\frac{1}{3\imath}-\frac{2}{3\imath}+6$

taking LCM

$\frac{1-2}{3\imath}+6$

$\frac{-1}{3\imath}+6$

taking LCM

$\frac{-1+18\imath}{3\imath}$

splitting the term

$\frac{-1+18\imath}{3\imath}$

splitting the term

$-\frac{1}{3\imath}+\frac{18\imath}{3\imath}$

$-\frac{1\times3\imath}{3\imath \times \imath}+6$

$-\frac{i}{3\imath^2}+6$

we know that

$\imath^2=-1$

putting this value in above equation

$\frac{\imath}{3}+6$

The diagram shows a cuboid<br> What is the surface area of the cuboid?<br> 4cm,5cm and 9cm

AveGali [126]

Answer:

surface area of a cuboid=2(L*W)+ 2(L*H)+ 2(W*H)

2(9*5)+2(9*4)+2(5*4)

$2 \times 45 + 2 \times 36 + 2 \times 20$

$90 + 72 + 40 = 202 {cm}^{2}$

insens350 [35]

The chance on flipping heads once is 1/2
so to get your answer all you have to do is multiply 1/2 by its self 3 times
(1/2)(1/2)(1/2)=1/8 or 0.125

If w/x=3, what does x/w equal

ruslelena [56]

Answer:

The value of x/w is 1/3.

Step-by-step explanation:

Consider the provided expression w/x=3

We need to find the value of x/w.

$\frac{w}{x}=3$

Now multiply both the sides by x.

$\frac{w}{x}\times x=3x$

$w=3x$

Now divide both the sides by w.

$\frac{w}{w}=\frac{3x}{w}$

$1=\frac{3x}{w}$

Divide both the sides by 3.

$\frac{1}{3}=\frac{3x}{w}\times \frac{1}{3}$

$\frac{1}{3}=\frac{x}{w}$

Hence, the value of x/w is 1/3.
