Question

Find x
80=½ * 0.2 * x ² ​

Answer 1

To find the value of x, we can rearrange the equation and solve for x. Let's start by isolating x²:

80 = 0.2 * (1/2) * x²

Multiplying both sides by 2 to eliminate the fraction:

160 = 0.2 * x²

Dividing both sides by 0.2:

x² = 160 / 0.2

x² = 800

Taking the square root of both sides:

x = √800

x ≈ 28.28

Therefore, the value of x is approximately 28.28.

Answer 2

To find the value of x in the equation 80 = (1/2) * 0.2 * x², we can solve for x by isolating it on one side of the equation.

Explanation:

• Multiply both sides of the equation by 2 to remove the fraction:

2 * 80 = 0.2 * x²

160 = 0.2 * x²

• Divide both sides of the equation by 0.2 to isolate x²:

160 / 0.2 = x²

800 = x²

• Take the square root of both sides to solve for x:

√800 = √(x²)

√800 = x

• Simplifying the square root of 800:

x ≈ 28.28

Therefore, the value of x in the equation 80 = (1/2) * 0.2 * x² is approximately 28.28.
