So to divide the 8/9 by 2/9, just divide the numerator of the 8/9 by the numerator of 2/9. 8 / 2 = 4, so there are 4 groups of 2/9 in 8/9. 
 Then, Toby can make 4 bags of trail mix that are 2/9 pounds each.
 Hope this helps!

Suppose x(t) is the continuous-time function given by x(t) = 1 on the interval [0; 1] and x(t) = 0 elsewhere. a) Calculate the c
borishaifa [10]

Answer:

a) X( w ) = 1 /jw -   e^-jw / jw

b) X1(t) = 1  for  0.5  

   X1(t) = 0 for elsewhere

Step-by-step explanation:

x(t) continuous time function = 1

interval ( 0,1 )   also x(t) = 0 outside the given interval

a) Determine the continuous time Fourier transformation of x(t)

x( t ) = u(t) - u(t - 1 )

x ( w ) = 1 /jw -   e^-jw / jw

b) supposing x1(t) = x(2t)

x1(t) = u(t) - u ( t - 0.5 )

x1(t) = 1  for  0.5  

x1(t) = 0 for elsewhere
