Answer:

Number of students(n1)= 4,402

Step-by-step explanation:

Giving the following information:

Number of students= 4,512

Declining rate= 2.5%

<u>To calculate the number of students next year, we need to use the following formula:</u>

Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)

x= number of years

Number of students(n1)= 4,512/1.025

Number of students(n1)= 4,402

Answer:

2 oldies and 6 new releases

Step-by-step explanation:

let x equal number of oldies

let y equal number of new releases

2x + 4y = 28

x + y = 8

x = 8 - y

2(8 - y) + 4y = 28

16 - 2y + 4y = 28

2y = 28 - 16

2y = 12

y = 12/2

y = 6

x = 8 - y

x = 8 - 6

x = 2

(7b - 2) / (-a + 1)....a = -2, b = 3, c = -1/3
where is he c in this equation ? Because if I just use a and b, my answer is not an answer choice

(7b - 10) / (a - 1)...a = -1, b = 5, c = -2/3
same as before...where is the c in this equation

V = (pi) r^2* h
V = (pi)(5^2)(7)
V = (pi)(25)(7)
V = 175(pi)
