Answer:
267 students
Step-by-step explanation:
Number of students in a team (t) is proportional to number of honor roll students (n)
Mathematically, t = kn (k is constant
When t = 12, n = 8
k = t/n = 12/8 = 1.5
When t = 400
n = t/k = 400/1.5 = 267 (to the nearest whole number)
Answer: 9, subtract : 10, 12.5 : 11, 134.25 : 12 is the 3d answer

Plug in what we know:

Multiply:

Add this to the original amount.

So he will have $6000 in his account after 5 years.
Answer: 24.49 or 24.5 if rounded.
Step-by-step explanation: We have to use the pythagorean theorem of course...
a² + b² = c²
15² + 20² = c²
225 + 400 = c²
600 = c²

c = 24.49 (If we round to the nearest tenth then the answer is 24.5)
Step-by-step explanation:
3x - 5x - 4 - x^2 + 12x - 17x^2 - 16
= -2x - 20 - 18x^2 + 12x
= 10x - 20 - 18x^2
