Answer:

5cm

Step-by-step explanation:

Given data

Length= 3cm

Width= 4cm

Applying Pythagoras theorem

z^2= x^2+y^2

z^2= 3^2+ 4^2

z^2= 9+16

z^2= 25

square root both sides

z= √25

z= 5cm

Hence the diagonal is 5cm

The answer is 3/7 (Three over seven). You ADD the number of total possibilities (animal characters + human characters = 7 total characters) for the denominator and put in the number (or section) you're looking at as the numerator

TO TRANSMIT INFORMATION ON THE INTERNET, LARGE FILES ARE BROKEN INTO PACKETS OF SMALLER SIZES. EACH PACKET HAS 1,500 BYTES OF IN

stich3 [128]

Answer:

A. It would be needed 20 packets to transmit 30,000 bytes of information and B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Step-by-step explanation:

1. Let's review the information provided to us for solving the question:

Size of each packet of information = 1,500 bytes

Number of packets = P

Number of bytes of information = B

2. Let's answer the questions:

A. How many packets would be needed to transmit 30,000 bytes of information?

P = 30,000 ÷ 1,500

P = 20

It would be needed 20 packets to transmit 30,000 bytes of information

B. How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

The length of the side opposite B measures __ units

Sindrei [870]

For this case what we should do is observe the figure.

We note that the side opposite to vertex B is the AC side.

From here, we can see that the length of the AC segment is given by:

AC = 4

Therefore, the measurement on the side opposite to vertex B is equal to 4 units.

Answer:

The length of the side opposite B measures 4 units
