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.
Missing informations but this can be turned into y=4x-12
Answer: A is -8
Step-by-step explanation:
-6 times 6 = -36 then you would do -6 times -a = 6a then you would have
-36 + 6a = -84 then you would add 36 to both sides to get -48 then you would divided -48 by 6 to get -8

Step-by-step explanation:
=3
r=common ratio: 12/6=2; 6/3=2
r=2,
=
