Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
What do you mean by the term quantity?
quantities which are not mademade from major quantities
What are the dimensionless quantity?
A dimensionless quantity is one that has only a number, not a unit, and should therefore be the same in any system of units. This often happens when a quantity is the ratio of two measurements of the same kind. For example, the index of refraction can be considered the ratio of two speeds (the speed of light in a vacuum, and the speed of light in the corresponding substance); if both speeds are expressed in meters/second, when taking the ratio, the units disappear, and only a number without units - a "dimensionless" unit - remains. If you convert the speeds in this example to some other unit, for example kilometers per second, both speeds will be a thousand times less; but the ratio will still be the same.
Define the term velocity. what are its various units Is it a scalar or vector quantity?
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
What phrase describes speed A. A quantity with direction only B. A quantity with no units C. A vector quantity D. A scalar quantity?
D
What quantity do units represent in a value?
they show the magnitude
Does a quantity have different dimensions in different systems of units?
No. The dimensions are: Mass, Length, Time, and Charge. They transcend the systems of units. For example, speed will always have the dimensions of (Length)/(Time), regardless of the system of units.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.

What is the dimensions of 4 cubic feet?
The dimension can't be determined here since 4 cubic feet is actually the quantity of the volume units. "cubic feet" doesn't determine the dimension. It determines the volume of the object.
What is joules to the decimal place?
A decimal representation does not imply a change in the measurement units. So a quantity of joules, to the [unspecified] decimal place is still a quantity of joules. If this is required then you need to specify the units into which the quantity is to be converted.
What are the system defined dimensions in sap bi?
Sap has 3 pre-defined dimensions which are, 1.Data Package Dimension---which will hold the request number 2.Time dimension------will hold values like 0calday, 0calmonth, 3.Unit Dimension-------will hold values for references like currency,units for quantity.
How long is the diagonal dimension of a rectangle with the dimension of 100 by 120?
156.2 units.

Definition of linear dimension?
For example, on a number line (which is one dimensional object), we measure the distance of two points in units. For example, the distance between 2 and 4 is 2 units. Any nth side of a polygon, can be measured by using linear units, such as cm, in., ft, km, etc. The circumference of a circle, the length of an arc, also are measured by linear units. A unit that is used to measure the distance between two points, is called linear dimension.
Define the term velocity. what are its various units Is it a scalar or vector quantity?
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
What does units agree mean?
In mathematics, two quantities are said to be in units agreement if they have the same units of measure. For example, if two quantities are both measured in meters, then they are in units agreement. If one quantity is measured in meters and the other is measured in centimeters, then they are not in units agreement.
