Answer: Velocity needs both magnitude and direction
Step-by-step explanation:
Velocity is defined as a Vector quantity which implies that one needs to know both the magnitude and the direction of the object, as a reference frame. The expression for velocity is defined as:
Velocity = Distance * Time <=> V= dt
Acceleration occurs when an object initially moving with a constant velocity, changes motion and velocity increases with time. The expression for acceleration is defined as:
Acceleration = Velocity * Time <=> A= Vt
A typical example of acceleration is a Free Falling Object (i.e. letting a ball drop from a building)
Answer:
D. 0.925x + 0.88y = 0.91(x + y)
Step-by-step explanation:
The important point to remember is that the total mass of pure silver is the same on each side of the equation.
0.925x = mass of pure silver in first alloy
0.88 y = mass of pure silver in second alloy
The final alloy has a mass of (x + y) g and is 91 % pure silver, so
0.925x + 0.88y = 0.91(x + y)
Answer:
6x-7+32/4x+2
Step-by-step explanation:
Divide using polynomial division
64 lb = 29.0299 KG
Rounding to the nearest hundredth, it's 29.03 KG
