Answer:
23 2/5
Step-by-step explanation:
convert mixed numbers to improper fractions: 1 3/10=13/10
13/10*18
convert element to fraction: 18=18/1
=18/1*13/10
cross cancel common factor:2
=13/5*9/1
multiply fractions
=13*9/5*1
=117/5
convert improper fraction to mixed numbers
23 2/5

Slope intercept form is y=mx+b where m=slope and b=yintercept so
3x-7y=11
add 7y to both sideds
3x=11+7y
subtract 11 from both sides
3x-11=7y
divide both sides by 7
3/7x-11/7=y
y=3/7x-11/7
slope is 3/7
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.
