Yes it was reasonable. I say it is resonable because if you multiply 44 times 25 it is 1,100 so the estimate was close enough
60,000,000,000 in scientific notation is 6 x 10^10 so you move the decimal 10 times.
Answer:
A- 5 meters in 0.1 seconds
Step-by-step explanation:
M/s means meters in 1 second and A says 5 meters in 1 second
W is width
W+9 is length
W+W+9=54
2w=45
45/2
W=22.5
Width is 22.5 length is 31.5
5 + 2 = 7
1/4 + 3/4 = 1
7 + 1 = 8
Your answer is 8
