Answer:
s = 22t or 
, when s is students and t is teachers.
Step-by-step explanation:
I. Given t = teacher, s = student
When 1 teacher per 22 students so...
s = 22t
If there're 10 teachers
s = 22(10)
= 220 or
Hope that help :)

Answer:
SA = 1,176 ft².
Step-by-step explanation:
To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.
For the rectangular base: (Use formula l×w)
20 × 18 = 360 ft²
For the triangular faces: (Use formula 1/2(b·h)
1/2(18 × 12) = 108 ft²
Since there are two faces, we need to double the amount.
108 × 2 = 216 ft².
Finally, solve for the lateral sides:
20 × 15 = 300 ft².
There are two sides, so:
300 × 2 = 600 ft².
Add up all of these areas:
600 + 216 + 360 = 1,176 ft²
Answer:
9sqrt2.
Step-by-step explanation:
sqrt8 + 3sqrt2 + sqrt32
= sqrt4 * sqrt2 + 3 sqrt2 + sqrt16 * sqrt2
= 2sqrt2 + 3sqrt2 + 4 sqrt2
= 9 sqrt2.
