Answer:
2. 13
Step-by-step explanation:
The least number of classes need for all of the students to be registered in a class is 13 since you want all of the stuednts to be registered so no one should be left out. If we do 12*12 (12 students in each class and there are 12 classes), that would only let 144 students take the swimming classes and 8 students would be left out. We don't want that though since we want all of the students to be registered. So let's go to 12*13 (12 students in each class and there are 13 classes), that would let 156 students take the swimming class. 156>152 so therefore, 13 classes would allow for all 152 students to be registered and it is the least number of classes needed for all the students to be registered in a class (plus you would have 4 seats left for anyone who wants to register in the future but the remainder doesn't matter).
Answer:
31 2/3
Step-by-step explanation:
You have to multiply 6 1/3 by 5 in order to get 31 2/3.
First term: a: 5/6
2nd term: 3/2 = 9/6
3rd term: 13/6
4th term: 17/6
a(n+1)=a(n) + 4/6, or a(n+1) = a(n) + 2/3, with a(1) = 5/6
