2/3 and 4/6 lines up the same :)
4 1/5a-2.2=
4 1/5a=4.2a So,
4.2a-2.2=2a
__________
-1 4/5a+3.8=
-1 4/5a=-1.8a So,
-1.8a+3.8=+5.6
I think that is it!
Answer:
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
Consider the diagram.
The length of segment QS is 2, 5, 17, 33 units.
