Answer:

25000m/s

Step-by-step explanation:

The following formula is used to calculate the speed or velocity of a wave.

V = f * w

Where V is the velocity (m/s)

f is the frequency (hz)

w is the wavelength (m)

First, determine the frequency.

Calculate the frequency of the wave.

Next, determine the wavelength.

Calculate the wavelength of the wave.

Finally, calculate the wave speed.

Using the formula above, calculate the wave speed.

Please help im not very sure what any of this means
BaLLatris [955]

Answer:

∠JKH and ∠GHF

Step-by-step explanation:

<em>hey there,</em>

<em />

< Corresponding means "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." The lines here are parallel so they are equal.

If you don't understand the meaning of the angles also, feel free to ask me about that too.

The two angles I listed are equal to equal to each other. When you look at the other options, they aren't equal, they might look less or more degrees.

If this won't be a multiple choice but short answer, try looking at angles that look similar and see if they would be able to match with the angle given. >

<u>Hope this helps! Feel free to ask anything else.</u>

I don't know if it's supposed to do with (n-2)180 <br> Also please explain :D
Sindrei [870]

Step-by-step explanation:

sum \:  of \:  interior  \\ \:  angels  \: is  \: 2340 \:  degrees. \\ (n−2)⋅180=2340 \\ 180n - 360=2340  \\ 180n = 2700 \\ n=15 \\  number \:  of \:  sides=15

the polygon is 15 sided.

10. If the sum of the measures of the interior
BigorU [14]

Answer: 32 sides

Step-by-step explanation:

Formula for interior angle of a polygon = ( n - 2 )180°, where n is the number of sides of the polygon

Now equate the formula to 5400°

( n - 2 ) × 180° = 5400°

open bracket by multiply by 180°

180n° - 360° = 5400°

          180n° = 5400° + 360°

          180n° = 5760

                 n = ⁵⁷⁶⁰/₁₈₀

                 n = 32

so the polygon has 32 sides
