Answer:
6.75 hrs are missing
Step-by-step explanation:
First, change all fractions into decimals:
8 = 8
7 1/4 = 7 + 0.25 = 7.25
8 1/2 = 8 + 0.50 = 8.50
Next, add all numbers gotten together:
8 + 7.25 + 8.50 = 23.75
Subtract the number gotten from the total
30.5 - 23.75 = 6.75

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)
5•3•x•x•x-5•x•x•y+5•x•y=
5x(3x^2-xy+y)
Hope this explanation helps
