Halfway between the numbers 2 and 6.5 is the rational number 4.25. I hope this helps!
Answer:
The table that has a consistent proportionality between Y and X of 2 is choice 2.
Step-by-step explanation:
Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.
Area = Length x Width
Width = Area / Length
25/54 / 5/9
This is the same as:
25/54 x 9/5
225/270 is your answer
this can simplify to 5/6
B. 12/24 is not equivalent because that is equal to 1/2 and 1/2 does not equal 8/20
Answer: A person’s height in centimeters, that same person’s height in inches would be a function.
Step-by-step explanation:
A relation is said to be a function if it has one single output for each input.
A relation is not said to be a function if any single input has two outputs.
First option is not a function as two person with same age can have two different heights.
Second option is not a function as two person with same weight can have different height .
Third option is a function as If two persons height is same in centimeters then it will same in inches too. Therefore here is only one output for each input.
Fourth option is not a function as it can happen that two persons using same telephone number can have different height.
