Are the two statements equivalent the ratio of orange. to blue is 3 to 4 <br><br>please help
Anestetic [448]

Answer:

Although I'm not entirely sure of the question (sorry lol), any ratio that is 1.5:2 , 6:8 , 9:12 , 12:18 etc would be equivalent to 3 to 4.

Step-by-step explanation:

If you divide both 3 and 4 by 2 you'd wind up with 1.5 ( 3 ) and 2 ( 4 ). When multiplying, you'd get 3x2 = 6 and 4x2=8, 3x3 = 9 and 4x3 = 12 and so on.

Helpppppppppppppppppppppppppppp
skad [1K]
Answer:
1760 Hz

Explanation:
The equation for the displacement has the following general formula:
d = A sin(wt)
where:
A is the amplitude
w is the angular frequency

the given equation is:
d = 0.6 sin(3520πt)
We can note that:
w = 3520 π rad/sec

Now,
w = 2πf where f is the frequency
Therefore:
3520π = 2π*frequency
This means that:
frequency = 1760 Hz

Hope this helps :)
