Answer:
1/2 a box
Step-by-step explanation:
as you are sharing 4 objects between 8 people, all you have to do is divide them.
4 ÷ 8 = 0.5 (1/2)
Answer:
subtract 3 from both sides of the equation
Step-by-step explanation:
5x -3>2
+3. +3
5x>5
Since they gave you the boxes you need the first number to be zero therefore having the quotient starting with zero. Then you may divide normally
Should be 63 for that one i believe
Answer:
1) The distance between two consecuitive peaks is called the wavelenght, so:
A = wavelenght.
The middle of the wave is called the rest position, so:
D = Rest position.
The distance between a peak and trough is called the wave heigt, so:
C = Wave height.
The distance between the rest position and a peak or a trough, is called the amplitude of the wave:
B = Amplitude.
2) Usually in high frequency waves we have shorter wavelenghts and in low frequency waves whe have larger wavenelgths, this is because the relation between frequency and wavelenght comes from:
velocity = wavelength*frequency.
if the velocity is constant, and we have a increace in the frequency, the wavelenght must decrease (so the velocity remains constant).
The same happens if the frequency decreases, the wavelenght must increase.
