C) 18 because you could get 6 numbers with red, 6 numbers with brown and 6 numbers with yellow.
We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
The formula for the amount A in an account with principal P and interest rate r compounded annually for t years is
... A(t) = P(1+r)^t
You want to find A when P=400, r=0.05, and t=3. Substituting those values gives you
... A(3) = 400·(1 +0.05)³
The appropriate choice is
... A. A(3) = 400·(1 +0.05)³

Answer:
R: √(13)
Step-by-step explanation:
Distance formula:
r^2 = (x-h)^2 + (y-k)^2
Center: (h,k)=(-1,5)
Circle: all points of (x,y)=(-3,2)
r^2=(-3+1)^2 + (2-5)^2
r^2=(-2)^2 + (-3)^2
r^2= 4 + 9
r^2=13 ((r^2)^(1/2)) = 13^(1/2) = 3.6055
