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.
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.
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 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 one quantity is proportional to another, it indicates that one quantity is dependent on the other by a factor and increases/decreases with the other quantity. When the two quantities are equal, the output of both the quantities is said to be the same.

Which of the three variables that apply to equal amounts of gases are directly proportional Which are inversely proportional?
The following variables are directly proportional: Temperature and Pressure Temperature and Volume These variables are inversely proportional: Pressure and Volume
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.
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 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.
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 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.
Why does an object with twice the mass of another weigh twice as much?
In the same gravity, downward force (weight) is directly proportional to the mass. (F=mA) If you had two objects of equal mass, and combined them, the weight would be the same as the total of the two.
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.
How do linear and exponential functions change over equal intervals?
The linear function changes by an amount which is directly proportional to the size of the interval. The exponential changes by an amount which is proportional to the area underneath the curve. In the latter case, the change is approximately equal to the size of the interval multiplied by the average value of the function over the interval.
