I used to when I was younger.
Set it up as a proportion.
x/9 = 1/3
1/3 = 3/9
x/9 = 3/9
x = 3
If the tenths place is 0-4, round down; if it is 5-9, round up:
317.38 becomes 317
82.21 becomes 82
317 + 82 = 399
Answer:
399
Hope this helps.
Use a squared + b squared = c squared
60x60=3600
30x30=900
3600+900=3660
Square root 3660
=60.49
Rounded is 60 inches
Answer:
Option C. Independent Variable: time, Dependent Variable: net profit
Graph starts out rising and starts falling mid-year. At the beginning of 2006 it is at the minimum value and begins rising again before staying at a fairly constant rate for the remainder of the year

y-----> the net profit
we know that
The independent variable is the time (variable x)
The dependent variable is the net profit (variable y)
