Answer:
Range for third side is
(
5
,
25
) cm.
Step-by-step explanation:
As two sides of triangle are 10 and 15
,
the third side would have to be less than the sum of other two sides i.e. less than 25 cm.
On the other hand if it is smaller one than this side plus side of length 10
should be greater than 15 and therefore
this side is greater than 15
−
10
=
5 cm.
Hence range is
(
5
,
25
)
Hope this answer helps you :)

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.
