Answer: 8 meters per second
Step-by-step explanation:
Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:
10 /20 = 0.5 seconds per wave
Now, we simply divide the distance given by the time, to obtain the speed rate:
4/0.5 = 8 meters per second

Answer:
A. y=-0.5x-2.5
Step-by-step explanation:
To figure out the equation of a line, use the formula y=mx+b, where x and y are the co-ordinate values, m is the slope and b is the y-intercept (where the line cuts the y-axis).
The slope, m, is calculated by dividing the y-difference (in this case, -2.5) by the x-difference (5): -2.5/5 = -0.5
From the diagram, we can see the line cuts the y-axis at (0,-2.5). Therefore b=-2.5
Sub in our values to get: y=-0.5x-2.5
Answer:
5(a-b)=3(a+b)
5a-5b=3a+3b
2a-2b=0
2a=2b
a=b
a:b=1
