Answer c: 2 and 3
Of course Q is on plane PQR. If S is as well, then QS is as well.
Answer:
45 ways
Step-by-step explanation:
We are given;
there are 3 different math courses, 3 different science courses, and 5 different history courses.
Thus;
Number ways to take math course = 3
The number of ways to take science course = 3
The number of ways to take history course = 5
Now, if a student must take one of each course, the different ways it can be done is;
possible ways = 3 x 3 x 5 = 45 ways.
Thus, number of different ways in which a student must take one of each subject is 45 ways.
System A has ONE real solution
System B has NO real solutions
System C has ONE real solution
Adding 220 + 360 = 580 total students.
5% of 580
(5/100)*580 = 29
29 teachers are employed
1 kg--> 0.264 kg fat
:. 12.5 kg--> (0.264*12.5) 3.3 kg fat
