The pressure applied to a leverage bar varies inversely as the distance from the object. If 150 pounds is required for a distance of 10 inches from the object, how much pressure is needed for a distance of 3 inches? 450 pounds 500 pounds 45 pounds 5 pounds

## Step1: Define the inverse relationship### The pressure and distance have an inverse relationship, defined as , where is the constant.## Step2: Calculate the constant ### Given pounds and inches, we substitute these values into the equation: . ## Step3: Solve for new pressure at 3 inches### Using the constant and new distance inches, we solve for :
