Answer:
34 minutes
Step-by-step explanation:
Given


Required
Number of minutes left to spend (x)
Since there's only 1 minute left to spend on every other call;
Time left = x * 1
Time left = x
The required can further be calculated using:

This gives:

Subtract 6 from both sides


<em>Hence, there are 34 minutes left to spend</em>
Answer:

Step-by-step explanation:
So the point-slope formula looks like this: 
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
Answer:
I'm a bit confused with your question.
Maybe this guy Sayurki can help ! He said this - "Set of unconnected points because you can't buy a part of a DVD in a line there are infinite points and when buying something such as a DVD to reach that infinite u need to be able to buy part of a DVD which technically isn't possible so that why is unconnected points u buy a full DVD not part "

Answer:
Total number of students surveyed about their mode of transportation to school is 400.
Step-by-step explanation:
Here, given student who uses car as their mode of transport = 120 students
We have to find the total number of students who are surveyed.
Also, since complete circle represents 100% of data,
Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.
Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%
Thus, percentage of students that uses car = 100 - 70 = 30%
Thus, 30 % of total students = 120
Mathematically, 30% of x = 120
Solving for x, we get,



Thus, total number of students surveyed about their mode of transportation to school is 400.
