<h3>Answer: B) 11.75</h3>

=================================================

Explanation:

Points B, C, and D are midpoints of triangle AFE. This is due to the similar tickmarks showing how the segments are congruent (eg: AB = BE).

Because we have D and B as midpoints, this means segment DB is a midsegment of triangle AFE.

FE = 23.5, so half that is (1/2)*FE = 0.5*23.5 = 11.75 which is the length of DB.

The midsegment DB is half as long as FE, and DB is parallel to FE.

Write the interval using interval notation to describe the set of values shown above.
jenyasd209 [6]

The interval on the number line is (-∞, 2) U [3, ∞)

<h3>How to determine the interval?</h3>

From the number line, we have the following inequalities

x < 2 and x ≥ 3

In inequalities, < and > are represented by brackets i.e. ( and )

While ≤ and ≥ are represented by square brackets i.e. [ and ]

So, we have:

x < 2 and x ≥ 3 = 2) and [3

The intervals must be closed and opened with infinity symbols.

So, we have:

x < 2 and x ≥ 3 = (-∞, 2) and [3, ∞)

Replace and with U

x < 2 and x ≥ 3 = (-∞, 2) U [3, ∞)

Hence, the interval on the number line is (-∞, 2) U [3, ∞)

At sunset the temperature was 4 dgrees. the next morning at sunset it was -7 degrees. what is the difference betweeen these temp
DedPeter [7]

The difference between these temperatures for the sunset is found as 11 degrees.

<h3>What is temperature difference?</h3>

In science, the term Delta T (ΔT) refers to the temperature between two measuring points. The temperature varies according to time and/or location.

Some key features regarding the temperature difference are-

  • Merus, for example, uses it to assess the effectiveness of such a heat exchanger.
  • Or to evaluate the effectiveness of a heating or cooling system.
  • A fourth letter of a Greek alphabet is, (Δ). Whereas is the capital letter symbol and the lower case letter.
  • The sign is also used in mathematics. Describes the "difference" between any two changeable quantities. T is a value in a process that represents a difference between two observed temperatures.

Now, according to the question;

Let the initial temperature be 'T' = 4 degrees.

Let the final temperature be 't' = -7 degrees.

Therefore, the temperature difference is;

ΔT =  T - t

     = 4 - (-7)

     = 4 + 7

ΔT = 11

Therefore, the difference between these temperatures is 11 degrees.
