Therefore, based on the given information, the estimated age of the tomb is approximately 3,970 years.

To estimate the age of the tomb based on the radioactive carbon-14 (C-14) content in the cypress beam, we can use the decay equation:

A = A₀ * e*(kt)

Where:

A = Final amount of radioactive substance (55% of the original C-14 content)

A₀ = Initial amount of radioactive substance (100% of the original C-14 content)

k = Decay constant (ln(2) / half-life of C-14)

t = Time (age of the tomb)

Given that the half-life of C-14 is approximately 5600 years, we can calculate the decay constant:

k = ln(2) / 5600 years

Now we can plug in the values:

0.55A₀ = A₀ * e*((ln(2) / 5600 years) * t)

Dividing both sides by A₀:

0.55 = e*((ln(2) / 5600 years) * t)

Taking the natural logarithm of both sides:

ln(0.55) = (ln(2) / 5600 years) * t

Now we can solve for t, the age of the tomb:

t = (ln(0.55) * 5600 years) / ln(2)

Evaluating the expression:

t ≈ 3,970 years

Answer: There are 114 red marbles contained in the bag containing 120 marbles.

Step-by-step explanation:

To find the amount of red marbles in the bag:

From the question, we can presume that for every 19 marbles in a bag, there exist a single black marble. This is the same case for the total number of marbles (both red and black) in each set is 20 marbles

Set of marbles: 120/20

Red marbles:

19r = 19 x 6

19r  = 114 red marbles.

The phrases that are inequalities are:

B) -2 < 2

D) 7w > 5.6

E) f - 4 - 7 > 7 - 4 - f

First, we define an equation as:

\(P = Q\)

Where P and Q are two expressions.

On the other hand, an inequality can be:

\(P > Q\\P < Q\\P \neq Q\\P \geq Q\\P \leq Q\)

These are inequalities because now the expressions P and Q can (and in some cases must) be different.

With that in mind, the phrases that are inequalities are:

B) -2 < 2

D) 7w > 5.6

E) f - 4 - 7 > 7 - 4 - f

Answer:

c) 27.9

Step-by-step explanation:

Since MN is the midsegment ,

MN = (AB + CD)/2

21.1 = (AB + 14.3)/2

21.1*2 = AB + 14.2

AB = 42.2 - 14.2

AB = 27.9

Answer:

C

Step-by-step explanation:

the midsegment is equal to half the sum of the parallel bases, that is

\(\frac{1}{2}\) (AB + CD) = MN ( substitute values )

\(\frac{1}{2}\) (AB + 14.3) = 21.1 ( multiply both sides by 2 to clear the fraction )

AB + 14.3 = 42.2 ( subtract 14.3 from both sides )

AB = 27.9 cm

The relationship between ∠1 and ∠3 is that they are equal in measure. In other words, ∠1 ≅ ∠3 due to the properties of corresponding angles formed by parallel lines and a transversal.

To determine the relationship between ∠1 and ∠3, we need to consider the properties of a solar dish and the nature of parallel rays.

In a solar dish, the rays of radiation from the Sun are parallel and converge towards the focal point. The focal point is where the receiver is located to collect the energy.

Since the rays are parallel, ∠1 and ∠3 are corresponding angles formed by a transversal intersecting two parallel lines. Corresponding angles are equal when the transversal intersects the parallel lines.

Therefore, The relationship between ∠1 and ∠3 is that they are equal in measure. In other words, ∠1 ≅ ∠3 due to the properties of corresponding angles formed by parallel lines and a transversal.

It will take 12 seconds until Hudson and Knox have run the same number of feet.

Let's denote the time it takes until Hudson and Knox have run the same number of feet as "t" (in seconds).

The distance Hudson runs can be calculated by multiplying his speed (8.8 feet/second) by the time "t". Thus, the distance Hudson covers is 8.8t feet.

Knox, on the other hand, had a head start of 30 feet. So the distance Knox covers can be calculated by multiplying his speed (6.3 feet/second) by the time "t" and adding the head start of 30 feet. Thus, the distance Knox covers is 6.3t + 30 feet.

To find the time when both runners have covered the same distance, we set their distances equal to each other:

8.8t = 6.3t + 30

Simplifying the equation:

2.5t = 30

Dividing both sides by 2.5:

t = 30 / 2.5

t = 12

Therefore, it will take 12 seconds until Hudson and Knox have run the same number of feet.

Answer:

42

Step-by-step explanation:

The measure of angle K is 48, the measure of angle m is 90. From there you have 138 degrees. A triangle is 180 degrees. You subtract 138 from 180.

The measure of angle J from the given triangle JKL is 42°.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

In the given triangle JKL and m∠JKM = 48°.

We know that, angle bisector in isosceles triangle is perpendicular bisector of base.

In triangle JKM,

m∠J+m∠JKM+m∠KMJ=180°

m∠J+48°+90°=180°

m∠J+138°=180°

m∠J=42°

In shape (i), there are two electron domains around the central atom. This means that the electron-domain geometry is linear. However, there are two bonding pairs and no lone pairs of electrons around the central atom, resulting in the molecular geometry also being linear.

The concept of electron-domain geometry and molecular geometry is essential in understanding the properties of molecules. The electron-domain geometry is determined by the number of electron domains (bonding or lone pairs) around the central atom in a molecule. On the other hand, the molecular geometry is determined by the arrangement of atoms in the molecule, taking into account the presence of lone pairs.

Knowing the electron-domain geometry and molecular geometry of a molecule is crucial in predicting its polarity and reactivity. For instance, polar molecules have an asymmetric distribution of electron density, while nonpolar molecules have a symmetric distribution. This difference in polarity affects the physical and chemical properties of a molecule, such as boiling point, melting point, and solubility.

In summary, in shape (i), both the electron-domain geometry and molecular geometry are linear, which means that the central atom has two bonding pairs and no lone pairs. Understanding the electron-domain and molecular geometry of molecules is essential in predicting their properties and behavior.
