If you say that one quantity is directly proportional to another quantity does this mean they are equal to each other?

No, not at all.
It means that when you double the first one, the second one also doubles. And if you reduce
one of them by 37.21 percent, the other one also reduces by 37.21 percent.
One of them might start out at 0.00006 and the other one might be 1,864,242,299,792,458 .
They're not equal, not even close. But if they're directly proportional, then multiplying or dividing
the first one by any number, causes the second one to multiply or divide by the same number.
The numbers may even be measured in different types of units; for instance, twice the force will produce twice the acceleration.
note: directly proportional tells only about the ratio of two quantities, the equality of the quantities is not taken into account. They could be equal, though this is not usually the case.

What does a quart equal as a fraction?
There can be no answer. A quart can be expressed as a fraction only in the context of another quantity of volume.
What is the difference between linear and non linear scales?
A linear scale is a scale with equal divisions for equal vales, for example a ruler. A non linear scale is where the relationship between the variables is not directly proportional.
Is this equation directly proportional y equal m times x plus b where b is a non zero number?
No. Although this an equation of a straight line and y increases when x increases, a directly proportional equation has y/x = constant. So if b is zero it is in direct proportion, but not if b is non zero
What dose it mean for two shapes to be similar?
Two shapes are similar when the sides of one are directly proportional to the corresponding sides of the other. That all the corresponding angles are equal.
What ratio of equivalent (equal) measurements that is used to convert a quantity from one unit to another unit is called a?
It is a conversion factor.
What is the difference between saying that one quantity is proportional to another and saying it is equal to another?
When two quantities are proportional, it means that they change in a consistent ratio. If one quantity is equal to another, it means that they have the same value. Proportional relationships involve a constant factor, while equal relationships involve identical values.
The pressure of an ideal gas is indirectly proportional to?
Other things being equal, it is directly proportional to the temperature. It is also directly proportional to the amount of gas.Other things being equal, it is directly proportional to the temperature.

Which of the three variables that apply to equal amounts of gases are directly proportional Which are inversely proportional?
Directly proportional: pressure and temperature (Boyle's Law and Charles's Law), inversely proportional: volume and pressure (Boyle's Law), volume and temperature (Charles's Law).
Why is the slope of the force versus acceleration plot equal to the object's mass?
The slope of the force versus acceleration plot is equal to the object's mass because acceleration is directly proportional to force when mass is constant (F = ma). Therefore, the slope represents the ratio of force applied to the resulting acceleration, which is mass in this case.
Is the inertia of a body equal to its mass?
No, inertia is the resistance of an object to changes in its state of motion, while mass is a measure of the amount of matter in an object. However, the greater the mass of an object, the greater its inertia.
Is acceleration directly proportional to mass?
Acceleration is directly proportional to the net force. Net force is equal to the mass times acceleration, taking this into consideration we can clearly see that acceleration is inversely proportional to mass.By Armah Ishmael Ryesa
What does it mean when 2 geometric figures are similar?
It means that the sides of one are directly proportional to the corresponding sides of the other. That all the corresponding angles are equal.
What does a quart equal as a fraction?
There can be no answer. A quart can be expressed as a fraction only in the context of another quantity of volume.
Why does an object with twice the mass of another weigh twice as much?
An object with twice the mass of another would weigh twice as much because weight is directly proportional to mass. When mass increases, the force of gravity acting on the object also increases, resulting in a greater weight. This relationship is described by Newton's second law of motion, which states that force (weight) is equal to mass multiplied by acceleration (gravity).
What is the difference between linear and non linear scales?
A linear scale is a scale with equal divisions for equal vales, for example a ruler. A non linear scale is where the relationship between the variables is not directly proportional.
When the amplitudes of waves are equal which frequency waves have the most energy?
When the amplitudes of waves are equal, waves with higher frequencies have more energy. This is because energy is directly proportional to frequency for waves with the same amplitude.
What is the law of unbalanced forces?
The law of unbalanced forces states that when two forces acting on an object are not equal in magnitude and opposite in direction, the object will accelerate in the direction of the greater force. This is described by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
