Answer:
r = 
r = 17.2 cm
Step-by-step explanation:
∵ The area of the circle A = πr²
∴ r² = A/π
∴ r = √(A/π)
∵ A = 54 cm²
∵ π = 22/7
∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm
Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48

Therefore,
Option D is the correct answer.
Answer:
The y values are decreasing, I would say it's decay.
102 ok i just have to write
<span>After deeply looking at the table it seems
z= .05
which means only 52% is less than Z
so, that is greater than z by 48%</span>
