There were exactly 31 people in chess club in 2002
Answer:
90 days.
Step-by-step explanation:
dy/dt = - 0.0032y
dy = -0.0032y dt
dy/y = -0.0032 dt
Integrating:
ln y = -0.0032t + c where c is some constant
y = e^(-0032t) + e^c
y = A e^(-0032t) where A is a constant.
At time 0 we can let y = 1 so in that case A = 1
When there is 0.75 of y left:
0.75 = e^-0032t
ln 0,75 = -0032 t
t = ln 0.75 / -0032
t = 90.

Answer:
n < -6
Step-by-step explanation:
-4n>24
Divide each side by -4, remembering to flip the inequality
-4n/-4 < 24/-4
n < -6
1) 2/3 <7/8
2) 2/4>2/6
3) 12000
4)
5)2x8=16
6) 9x4=36
4)1/3<3/4
5)3/4>1/4
6) Green group ate more pizza
7) Ben’s ride was longer
8)
The first 4 and 8 I didn’t do because I didn’t understand what they were asking for
