Answer:
Area of the shaded region = 6.88 cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
Length of the rectangle = AD = 8 cm
Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]
Area of the rectangle = 8 × 4 = 32 cm²
Area of the semicircle = 
= 
= 
= 25.12 cm²
Area of the shaded region = 32 - 25.12
= 6.88 cm²
Answer:
- <em><u>The reduction is 8.6%</u></em>
Explanation:
Call F the full monthly pension of a person retiring at 62.
If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:
Where r = 6 / 100 = 0.06, and t = number of years after retirement.
<u>For retirement at 65.5</u>:
<u>For retirement at 67</u>:
<u>Percent reduction of people who retire at 65.5 compared to what they would receive at 67</u>:
Answer:
Median = 13
Step-by-step explanation:
Arranging it in ascending order:
=> 2,4,6,10,13,13,14,16,20
Median is the middlemost no.
So,
=> Median = 13
Answer:
c-12
Step-by-step explanation:
Pythagoras theorem states that a²+b²=c²
144+b²=c²
b²=c²-144
b=c-12
b=x
x=c-12
