Answer:
The inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.
Step-by-step explanation:
From the information provided, the inequality would indicate that the phone bill for the month that is equal to the result of the fixed fee plus the price per minute for the number of minutes has to be less than $40, which can be expressed as:
15.95+0.10m<40
Now, you can solve for m:
15.95+0.10m<40
0.10m<40-15.95
0.10m<24.05
m<24.05/0.10
m<240.5
According to this, the answer is that the inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.
Answer:
We have to travel 26.93 units from platform B to C.
Step-by-step explanation:
Length of a segment having coordinates
and
is determined by the formula,

From the graph attached,
Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.
Distance between these points B and C Or length of BC will be,
BC = 
= 
= 
= 
= 26.93 units
Therefore, we have to travel 26.93 units from platform B to C.
