Suppose you need to deliver 40 terabytes of data to your co-workers in Atlanta (200 km). You have an available 100 Mbps dedicate

d link for data transfer. Alternatively, your friend raises homing pigeons and would be willing to let you borrow one. You have a single 1 TB SD card you can strap to the pigeon. Assume pigeons can fly 1000 km per day and that it takes no time to copy to/from the SD card.

Answer: All data will be sent in 89.39 hours

Step-by-step explanation:

Data transfer rate: 100 Mbps=100 \frac{Mb}{s} ×\frac{1Tb}{1024^{2} Mb}×\frac{3600s}{h}=0.3433 \frac{Tb}{h}

The pigeon can fly 1000 km/day and it needs to fly 400 km (round trip).

Pigeon rate: \frac{1000km}{24h}=41.67 \frac{km}{h}

Time of round trip: 400 km÷\frac{1000km}{24h}=9.6 h

So the pigeon can send 1 Tb every 9.6 hours.

If we sum the rates we can get the time for sending all the data:

40 Tb= (0.3433 Tb/h + 1 Tb/9.6h)×t

T= 89.39 hours

The equation P= 21 + 2w models the perimeter, P, of a rectangle with a length of / units and a width of w units.
natima [27]

Answer:

width = 10 units and length = 20 units

Step-by-step explanation:

Let the width be w

so Length will be 2w

using the rectangle formula:

\sf Perimeter \ of \ rectangle= 2L + 2W

\sf 60= 2(2w) + 2w

\sf 60= 4w + 2w

\sf 60= 6w

\sf w = 10 \ units

Find length:

\sf length = 2w

\sf length = 2(10)

\sf length = 20 \ units

| the British 50-pence coin shown on the right is in the shape of a
Sergio [31]

For a regular polygon with n sides, interior angle

= [(n-2) × 180°]/n

So, interior angle of this regular heptagon shape

= [(7 - 2) × 180°]/7

= (5 × 180°)/7

= 900°/7

= (900/7)°

= 128.571° [approximately]
