Answer:
21
Step-by-step explanation:
1 <span>millimeter = 10⁻³ m
1 </span><span>decimeter = 10⁻¹ m
So,</span>decimeters are larger units, and 143.0 decimeters > <span>143.0 millimeters .</span>
1: You are looking to find the mps increase over a second
2: 45 m/s from 0 m/s in 10 secs that is 4.5 m/s per second
3: The acceleration is 4.5m/s
X = 12
18/24 = .75
16 x .75 = 12
