Answer:
Central angle = θ = 2.5 radians
Step-by-step explanation:
The radian measure of central angle is given by
Where s is the arc length, r is the radius of circle and θ is angle in radians
We are given an arc length of 5 units
We are given radius of 2 units
Therefore, the central angle in radians is
Bonus:
Radian is a unit which we use to measure angles.
1 Radian is the angle that results in an arc having a length equal to the radius.
Degree is another unit that we use to measure angles.
There are 360° in a circle.
There are 2π radians in a circle.
Answer:
If 0.20 mole of Cl 2 is added to the equilibrium mixture, will the concentration of PCl 5 increase or decrease? If the equilibrium constant for this reaction is expressed in terms of concentrations, written as follows: Here, , and represent the molar concentrations of, , and respectively. Chapter 10, Problem 60CQ is solved.

Answer:
Step-by-step explanation:
5 min=2$
20 min left
so,
20*0.3 cents =6$
total cost for 25 min.=6+2=$8
Answer:
Step-by-step explanation:
Inequality and equality is that inequality is an unfair, not equal state while equality is (uncountable) the fact of being equal.
