Answer:
1) S(t) = C(t) × D(t)
2) S(t) = (400 + 30t)(25 + t)
Step-by-step explanation:
The function C(t) = 400 + 30t ........... (1), models the number of classrooms, C. in the town of Sirap, t years from now.
The function D(t) = 25 + t ......... (2) models the number of students per classroom, D, t years from now.
Then if S(t) represents the number of students in Sirap's school system t years from now, then, we can write the relation
1) S(t) = C(t) × D(t) (Answer)
2) Hence, the formula of S(t) in terms if t is given by
S(t) = (400 + 30t)(25 + t) (Answer)
Answer:
57/11 or 5 2/11
Step-by-step explanation:

57/11 = 5 2/11
Answer:
28∛3+72
Step-by-step explanation:
distribute: 28∛3+24∛3∛9 - be careful, ∛9 is not equal to 3! You are looking for three "copies" of a number since it is a ∛ not √.
28∛3+24∛(3*9)=28∛3+24*3 = 28∛3+72
