Answer: b:c =  9:20

Step-by-step explanation:

a:b = 2:3

That is

\frac{a}{b} = \frac{2}{3}

This means that

a = \frac{2}{3}b ................................... *

Also

a:c = 3: 10

\frac{a}{c} = \frac{3}{10}

which means that

a = \frac{3}{10}c .................................. **

Equate * and ** since they are both values of a

That is :

\frac{2}{3}b =\frac{3}{10}c

cross multiplying , we have

20b = 9c

Therefore :

\frac{b}{c}=\frac{9}{20}

Therefore :

b:c =  9:20

How long is line UW?
Neko [114]

Answer: UW= 9√3

Step-by-step explanation:

This right triangle is a 30-60-90 triangle. This is a special triangle. Since this is a special triangle, the hypotenuse is 2x.

The hypotenuse is 18. We can figure out the length of x.

2x=18

x=9

Since we got 9, you would think it is the answer, but it's not. The length across the 60° angle is x√3. Now that we know the length across from 60°, we can plug in x.

9√3

We can check our answer by using Pythagorean Theorem.

9²+(9√3)²=18²

81+243=18²

324=324

Since they are equal, we know we have the right answer.

Im not sure but i think its A because you have no value to multiply 3 so you just multiply it by itself.It would be a negative because you cant divide 3 by 2.so it would be A.-x9y2.
i hope i was correct and helped if not you can go ahead and delete my answer:)
