Option B:

The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.

Solution:

Given expression: |a| \leq 5

To find the equivalent expression for the given expression.

Apply absolute value rule:

<em>If |x| ≤ m  then -m ≤ x ≤ m.</em>

|a| \leq 5

⇒ -5 ≤ a ≤ 5

⇒ -5 ≤ a and a ≤ 5

Switch the sides, we get

⇒ a ≥ -5 and a ≤ 5

The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.

Option B is the correct answer.

TO TRANSMIT INFORMATION ON THE INTERNET, LARGE FILES ARE BROKEN INTO PACKETS OF SMALLER SIZES. EACH PACKET HAS 1,500 BYTES OF IN
borishaifa [10]

Answer:

<u>A. It would be needed 20 packets to transmit 30,000 bytes of information.</u>

<u>B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.</u>

Step-by-step explanation:

1. Let's review the data given 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

<u>It would be needed 20 packets to transmit 30,000 bytes of information</u>

<u>B. </u>How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

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

The statement <S and <H are equal in measure is False

<h3>How to determine the true statement?</h3>

The similarity statement is given as:

ΔRST is similar to ΔHGF

This means that:

  • Angles R and H are congruent
  • Angles S and G are congruent
  • Angles T and F are congruent

Hence, the statement <S and <H are equal in measure is False

Because S equals G and R equals H
