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 :
So, the wavelength of the sound wave is equal to 10.7 m.
If he got 5 points in the first round and he needed at least thirty he would score 9 points in the next three rounds
OK for number 3is 70because you add the number that they give you and then subtract 36 106 and you get your answer
(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138
Answer:
If the bacteria grow for six hours, each bacterium will divide 3 times per hour × 6 hours = 18 times.
Every time the bacteria reproduce, the number doubles.
