Answer:
Step-by-step explanation:
So we can just set up a proportion
14.5/2=x/3
we can cross multiply
so that means
2x=43.5
x=21.75
Find a common multiplier then divide ex. 21/27 = 7/9
Answer:
The answer is:
30 minutes.
Step-by-step explanation:
We are given the following information:
at 160 m/min, tool life = 5 min.
at 120 m/min, tool life = 17 min.
This means that as the speed reduced from 160 m/min to 120 m/min, the tool life increased from 5 min. to 17 min, hence the difference between the changes are:
speed = 160 - 120 = 40 m/min
tool life = 17 - 5 = 12 min.
Therefore, it can be concluded that a change of speed of 40 m/min, increases the tool life by 12 min.
40 m/min = 12 min
∴ 1 m/min = 12/40 min.
∴ 100 m/min = 12/40 × 100 = 0.3 × 100 =30 min.
Answer:
Exact form : x = 67/3
Decimal form : x = 22.33333333333...
Mixed Number form : x = 22 1/3
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.
I hope this helps you out. :)
For this case we propose a rule of three:
31700 ------------> 8.8%
x ----------------------> 100%
Where "x" represents the number of copies sold to date.
Thus, to date 360,227 copies of the book have been sold.
ANswer:
To date, 360,227 copies of the book have been sold.
