15(100) + 5d+ 20(50) + 7d=d
1500+ 1000+ 12d=d
2500+12d=d
20:30 so it becomes 2:3 as a fraction it would be 2/3. a fraction is basically a ratio.

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:
v=5.42m/s
Step-by-Step Explanation:
We can use conservation of energy to solve this
mgh=1/2mv^2
2gh=v^2
v=sqrt(2gh)
v=sqrt[2*9.8m/s^2*(6.5-5)]
v=5.42m/s
