Direct/Indirect Proportion Word Problems Spanish

Front

What is direct proportion?

Back

Direct proportion is a relationship between two quantities where an increase in one quantity results in a proportional increase in the other quantity. Mathematically, if y is directly proportional to x, then y = kx, where k is a constant.

Front

What is inverse proportion?

Back

Inverse proportion is a relationship between two quantities where an increase in one quantity results in a proportional decrease in the other quantity. Mathematically, if y is inversely proportional to x, then y = k/x, where k is a constant.

Front

How do you calculate horsepower from engine displacement?

Back

Horsepower can be calculated using the formula: Horsepower = (Displacement of engine / Displacement of known engine) * Horsepower of known engine.

Front

What is the formula for power gain in an amplifier circuit?

Back

The formula for power gain is: Power Gain = Output Power / Input Power.

Front

How do you determine the scale factor from a drawing?

Back

The scale factor can be determined by comparing the dimensions in the drawing to the actual dimensions. It is expressed as a ratio, such as 1:48.

Front

If a model is built to a scale of 1 in = 4 ft, how do you find the actual height of the object?

Back

To find the actual height, multiply the model height by the scale factor. For example, if the model is 12 inches tall, the actual height is 12 inches * 4 ft/in = 48 ft.

Front

What is the relationship between stopping distance and deceleration?

Back

The stopping distance is inversely proportional to the deceleration. This means that as deceleration increases, the stopping distance decreases.

Front

How do you calculate stopping distance when deceleration changes?

Back

To calculate the new stopping distance when deceleration changes, use the formula: New Stopping Distance = (Old Stopping Distance * Old Deceleration) / New Deceleration.

Front

What is the significance of the constant in proportional relationships?

Back

The constant in proportional relationships (k) represents the ratio of the two quantities and remains the same regardless of the values of the quantities.

Front

How can you apply direct and inverse proportions in real-world problems?

Back

Direct and inverse proportions can be applied in various real-world problems, such as calculating speed, distance, time, and in engineering applications like power and force.
