Answer:
65% of the marbles are red.
Step-by-step explanation:
I think you meant "wide." :) Since it is a pipe, you should know that it is the shape of a cylinder. Therefore, the formula would be: πr^2h. Substitute the height for h. (π(4.5)^2(13). Since it's 9 cm wide total, divide it by 2 to get the radius (part of formula), which is 4.5 So multiply π times 4.5^2 (which equals 20.25) times 13. This all will equal 826.605. You can simplify this decimal to 827. Therefore, the volume is 827 cm^3.
Answer:
Not all relationships are functions, but all functions are also relationships
Step-by-step explanation:
A relationship is a correspondence between two sets of values.
A relationship assigns values from an output set called range to a set and input called a domain.
On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).
In other words, if an input value
is assigned two or more output values

,
.. then the relationship is not a function. This means that <em>not all relationships are functions</em>.
is a relation but it is not a function.
because when x = 4 then y = 1 and y = 5.
Not all relationships are functions, but all functions are also relationships
