I'll do problem 1 to get you started.
The vertical sides are 3 and x for the left and right figures.
The horizontal sides are 15 and 60 for the left and right figures.
The corresponding sides form fractions which are equal (due to the nature of the similar polygons)
3/x = 15/60
3*60 = x*15 ... cross multiply
180 = 15x
15x = 180
x = 180/15 .... divide both sides by 15
x = 12
----------
Another way you can see this is note how the jump from 15 to 60 is "times 4", so the jump from 3 to x must also be "times 4" to keep the same proportion
3 ---> x = 3*4 = 12
Or you could set up the proportion
60/15 = x/3
4 = x/3
x/3 = 4
x = 3*4
x = 12
-----------

Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
Answer:C
Step-by-step explanation:
21/10 divided by 2 4/5 represents the time spent on a shift
<h3>How to determine what 21/10 divided by 2 4/5 represent in this situation?</h3>
The given parameters are
Time = 21/10
Shifts = 2 4/5
This means that:
21/10 divided by 2 4/5 represents:
Time/Shift
i.e. time per shift
Hence, 21/10 divided by 2 4/5 represents the time spent on a shift
