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

I said A the number of AP
Answer:
231.7 cm^2
Step-by-step explanation:
We can find the area by adding the area of the rectangle to the area of the 2 triangles.
The rectangle is
7+7+7 by 9
21 by 9
A = length * width
A = 21*9
A = 189
The triangles are identical so we find the area of one of them and multiply by 2
The base is 7 and the height is 6.1
A = 1/2 b*h
but since we have 2 of them
2A = 2*1/2 b*h
2A = b*h
2A = (7* 6.1)
= 42.7
Add the rectangles area to the area of the two triangles
189 + 42.7
231.7 cm^2
Answer: 22 miles
Step-by-step explanation:
1/4 times 4 = 1 gallon
if Rob can travel 5 and 1/2 miles on 1/4, then to find how far he can travel on 1 gallon we multiply 51/2 by 4
5 1/2 x 4 = 22
Answer:
y=-2x+7
Step-by-step explanation:
You just subtract 2x from both sides to get y alone
