Answer:
d. 42 degrees
Step-by-step explanation:
y and 92 are supplemetary angles, which means they both add up to 180 since they are on the straight line.
Hence,
y+92 = 180
y = 180-92
y=88
And now we also know that all the angles of a traingle add up to 180,
so, we can simply find the x by:
88+x+50 =180
138 + x =180
x = 180-138
x = 42

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.
