Mathematics

Aleksandr [31]2 years ago

Step-by-step explanation:

21. parallel

22.If two lines in a plane do not intersect, they are parallel. If two lines in space and not in the same plane do not intersect, they are skew. The answer is yes. Two lines can only be non-intersecting if their slopes are exactly the same (otherwise they'd have to cross at some point).

hope this helps you.

Please help, I really desperate
Paladinen [302]

Answer:

V candle ≈ 196.9 cm³

Step-by-step explanation:

Volume of cone = ( π·r²·h)/3

V candle = V big cone -V small cone

V candle = [ π·4²·(8+5) - π·2²·5]/3

V candle = ( π·16·13 - π·4·5)/3

V candle = (π·16·13 - π·4·5)/3

V candle = π·(208 - 20)/3

V candle = π·188/3

V candle = 196.8731396

V candle ≈ 196.9 cm³

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Earth is approximately 1.3×104 kilometers. About ho
-Dominant- [34]
Hi there!

To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

\frac{1.3*10^4}{4.9*10^3}

We can change this to

\frac{1.3}{4.9}*\frac{10^4}{10^3}

Let's solve for each individual fraction

\frac{1.3}{4.9} ≈ 0.27

\frac{10^4}{10^3} = 10

Now, multiply.

0.27 * 10 = 2.7

That's your answer.

Have an awesome day/night! :)
