Solution:

Given:

\frac{a}{b}\cdot\frac{c}{d}

Since b and d are nonzero elements, then it is the product of two rational numbers.

Multiplying two rational numbers produces another rational number.

Therefore, the product is a rational expression.

OPTION C is the correct answer.

Geometry help please!!
Nostrana [21]

Answer: 13

Step-by-step explanation:

Equilateral triangle means that all sides are equal

Soo

3x + 1 must be equal to 5x - 9

3x + 1 = 5x - 9

-2x = -10

x = 5

Substitute x as 5 into either side value

3(5) + 1 = 15 + 1 = 16

So, all sides equal 16

Which means that y + 3 also equals 16

y + 3 = 16

y = 13

Triangles QVS and RTS are similar. Find side VS.
tekilochka [14]

In order to solve the equation, set up a proportion. Use the similar sides together!

1. 16/8 = x/20.... Similar sides are in one ratio and they equal another ratio...."x" represents the side of VS

2.Solve for "x" by cross multiplying: 8x = 320

3. Divide by 8 to find "x": x = 40

Side VS equals 40. Hope this helped :)

Select the correct answer from each drop-down menu.

<u>Answer:</u>

Planet A is inner  

Planet A is Mars

Planet B is Outer

Planet B is Uranus

<u>Solution:</u>

We know that the inner planets are the planets which are close to the sun. They are relatively small, mostly rocky composition, and have few or no moons.

On other hand, the outer planets are the planets which are far away from the sun. They are mostly huge, ringed, gaseous and have several moons.

In the given problem,  

Planet A has rocky mantle and iron core, less no of Moons and no rings, also due to 96% of carbon dioxide, 3% nitrogen and 1% other gases this is denser, and Hence Planet A is inner planet. As the distance from the sun is 1.5 AU and no of moons are 2, hence Planet A is Mars.

On the other hand, Planet B is gaseous with hydrogen and helium gas, hence it is also denser and it has large no of moons and faint rings. So Planet B is Outer planet. As the distance of the planet is 19.22 AU and has 27 moons, hence Planet B is Uranus.
