Vol. of a rectangular box is L*W*H.

Here, that comes to V = (4.5 in)(9 in)(6.5 in) = 263.25 cubic inches.

A bird leaves its nest and travels 20 miles per hour downwind for x hours. On the return trip, the bird travels 4 miles per hour
Svetach [21]

Answer:

30 mi/ 24 mi (6 mi slower)

Step-by-step explanation:

distance = rate x time

distance = 20 mph * X hr = 20 X miles

return trip:

    distance = 16 mph * X hr + 6 miles = 16X + 6

They are the same:

 20X = 16X + 6

 4X = 6

 X = 6/4 = 3/2

20 mph * 3/2 hr = 30 miles.

On the return trip: 16 mph * 3/2 hr = 24 miles, which is 6 miles short of 30 mi.

The distance is 30 miles.

The bird flies all 30 miles in 3/2 hr = 1 and 1/2 hour = 1 hour 30 minutes.

On the return trip, the bird flies 24 miles in 1.5 hours, which is 6 miles short.

Given the following signal:  x(n) = {4, −1, 2, 5, − 2, 3}  Compute the 6-point DFT of x(n) directly from the DFT equation  −
FrozenT [24]

Answer:

Computing the 6-Point DFT of x(n), where X = 0,1,2,3,4,5

x(0) = 11

x(1) = 21/8 -j13/8

x(2) = 27/8 + j33/32

x(3) = 1139/256 + j91/256

x(4) = 4389/1024

x(5) = 4.14685 - j1379/8192

Step-by-step explanation:

See the picture for workings.

Given X(n) = { 4, -1, 2, 5, -2, 3}

Six point DFT implies that N = 6

Step 1 = write out equation X(k)

Step 2 = substitute "Wn" in the equation X(k) to give a new equation

Step 3 = when N=6, substitute for "N" in the new equation and simplify the new X(k) equation.

Step 4 = use 0, 1, 2, 3, 4, 5 in finding the DFT

You can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb  and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by  additional 1550 of songs that is  
7750/1550 = 5

so, a total of 5 songs and 11 pictures were  sold..

hope it helped
