2A) first find the measure of the angle above the right angle (180-122=58) so it equals 58°, while the right angle is obviously 90°. the whole triangle should be 180° so 90+58= 148. now we subtract this from 180 to get the measure for x. 180-148=32.

Therefore, x=32°

A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?

GaryK [48]

Answer:

10.7 m

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 6,420 m/s

The frequency of the wave, f = 600 Hz

We need to find the wavelength of the wave. We can find it using the below relation as follows :

$v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m$

So, the wavelength of the sound wave is equal to 10.7 m.

Can someone help plz

Answer:

A.) 2x - 9x - 30 = -6

Step-by-step explanation:

hello !

to solve this system of equations, first, we substitute the equation $y = 3x + 10$ to the <em>y </em>variable in the equation $2x-3y = -6$ . Therefore, we get:

$2x - 3(3x+10)=-6$

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

$2x - 9x - 30 = -6$
