Hey there! Hello!
This can be represented by the equation y=2.54x, where:
y=measurement in inches
x=measurement in cm
You can plug any value into this problem to reveal that this is a linear function. I provided a graph of this to further prove the point.
Hope this helped you out, feel free to ask any additional questions if you need further clarification! :-)

Answer:
6 L
Step-by-step explanation:
Given two solutions:
1st solution is 90% saline solution. Let the volume of this solution be litres.
2nd solution is 50% saline solution. Volume of this solution = 4 L
Resultant solution is 74% saline.
To find:
The volume of 1st solution = ?
Solution:
Total volume of the 74% saline mixture = (4+) Litres
We can write equation here, as per the percentage of saline in the mixtures.
90% of L + 50% of 4 L = 74% of (
+4)
Therefore, the volume must be <em>6 L</em>.
Answer:
Part 1) The scale factor is
Part 2) The altitude QS is
Part 3) The scale factor is
Part 4) The value of x is
Part 5) The perimeter of ABCDE is
Step-by-step explanation:
Part 1) Find the scale factor of triangle TQR to triangle NQP
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z-----> the scale factor
substitute the values
Part 2) Find the length of the altitude QS
we know that
To find the altitude QS, divide the altitude of triangle NQP by the scale factor
so
Part 3) Find the scale factor of FGHJK to ABCDE
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z-----> the scale factor
substitute the values
Part 4) Find the value of x
we know that
The value of x is equal to multiply the length side FK by the scale factor
so
substitute the values
Part 5) Find the perimeter of ABCDE
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of ABCDE
y-----> the perimeter of FGHJK
we have
substitute the values
