nirvana33 [79]

Answer:

r = \sqrt{\frac{A}{\pi } }

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

What is the value of y in the solution to the following system of equations?
lukranit [14]

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

\frac{24y}{24}=\frac{48}{24}\\y=2

Therefore,

Option D is the correct answer.

Use a table to find a z-score that fits the given conditions. Interpolate if necessary.
kotegsom [21]
<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>
