A central angle in a circle with a radius of 7in. intercepts an arc with a length of 9in. What is the radian measure of the central angle?
Answer:
Use the Quadratic formula
Answer:
Exact form: x = 27/5
Decimal form: x = 5.4
Mixed-number form: x = 5 2/5

It has been given in the question that Mary's team had lost 30% of the total of 20 games. There has been no ties for this team. It is required to find the number of matches that Mary's team lost.
Total number of games played = 20
Percentage of games lost by Mary's team = 30%
Number of games lost by Mary's team = (30/100) * 20
= 3 * 2
= 6
So Mary's team lost 6 games in all. I hope this is the answer you were looking for. The process is easy once you understand the words of the problem.
The equation is true.
y^13/y^12 = y^8 * y^-9
y=y^8 * y^-9
y=y^-1
y=1/y
y-1/y=0
y
y^2 - 1 = 0
y = 1 , -1
