Proportionality or variation is state of relationship or
correlation between two variables It has two types: direct variation or
proportion which states both variables are positively correlation. It is when
both the variables increase or decrease together. On the contrary, indirect
variation or proportion indicates negative relationship or correlation. Elaborately,
the opposite of what happens to direct variation. One increases with the other
variables, you got it, decreases. This correlations are important to consider
because you can determine and identify how two variables relates with one
another.
Notice x = y (direct), y=1/x (indirect)
Answer:
10 people
Step-by-step explanation:
Count the x's for more than 1 scarf, which is 2 or 3 scarfs
2 = 9
3 =1
total = 10
The value of x is 
Step-by-step explanation:
Given:
Rearranging the radical on left side,
Power on both sides,
Simplifying the left,
For the RHS equation, use the property of (a-b)² = (a²-2ab+b²),
Now calculating its powers,
Now sending -4√x to the LHS (left side), its sign becomes plus (+),
Now the +x and -x will be cancelled,
Bringing 4 to the right side, it becomes the denominator,
Now powering both sides,
Answer:
900
Step-by-step explanation
The hundreds place is the third one from the decimal to the left. If the tens place is greater that 50, round up , giving you 900
