Answer:
His average speed is 4.75 m/s
Step-by-step explanation:
Here, we are interested in calculating the average speed of the boy.
At time t = 4 seconds, total distance traveled = 6 meters
The average speed here is distance/time = 6/4 = 1.5 m/s
Now at time 30 7 seconds , he has rolled 30 meters
What this actually means is that for the next 3 seconds after the initial 4 seconds, he rolled a total distance of 30-6 = 24 meters. Hence, he rolled 24 meters in the next three seconds
So mathematically, his average speed for the second part of the rolling is 24/3 = 8 meters per second
Conclusively therefore , his average speed will be (1.5 + 8)/2 = 9.5/2 = 4.75 meters per second
-1/2 and 3/4 =
-2/4 and 3/4
Together they make 1/4
A. 3^n 3^20
b.N^n N^20
c.12^n 12^9
d.237^n 237^4
Simple...
you have: 27-9x+15
Add any terms that are the same-->>
-9x+42
Factor-->>>
-3(3x-14)
Thus, your answer.
Answer:
0
Step-by-step explanation:
150 + 170 + 30 = 350
170 + 30 = 200
200 + 150 = 350
Hope this helps! :)
