Answer:
you can use reciprocal and quotient formula of trigonometry
Answer:
B should be the answer but it could but C
The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3
Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3
So the answer is letter b.
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
