If the height of seven and three fourths yards and a base of 20 yards, then the area of the right triangle is 77.5 square yards.

To calculate the area of a right triangle, we can use the formula:

Area = (base * height) / 2

where the base is one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.

In this case, the height of the right triangle is 7 and 3/4 yards, and the base is 20 yards. Plugging these values into the formula, we get:

Area = (20 * 7.75) / 2 = 155 / 2 = 77.5 square yards

In summary, to calculate the area of a right triangle, we can use the formula that relates the base and height to the area. In this case, we needed to use the given values of the height and base of the right triangle to compute the area in square yards.

The resulting area represents the amount of surface inside the triangle and is useful in many applications, such as geometry, physics, and engineering.

The measure of the other angle of the parallelogram is 22 degrees.

Opposite angles of a parallelogram are equal (or congruent).

Let the missing angle be represented by x.

Since the opposite angles of a parallelogram are equal (or congruent).

x = 2x - 22

Solve for x

2x - 22 = x

2x = 22 + x

2x - x = 22

x = 22°

Therefore, 22 degrees is the measure of the other angle.

Step-by-step explanation:

We know that the store sells nuts for $2 per pound and chocolate for $0.95 per pound. We also know that x represents the total pounds of nuts, and 32 represents the total pounds of chocolate.

In order to write an equation that represents a mixture that costs $1.48 per pound, we first need to find an expression to represent the total pounds in this situation, which would be (x + 32).

Now that we have this, let's just combine everything we know into one equation:

2x + 0.95(32) = 1.48(x + 32)

Therefore, the correct answer choice is option B.

No, I do not agree with Bard. The area of the given circle is 12.56 unit²and, not 3.5 unit² which Bard claims to be.

What is a circle?

A circle is a shape made up of all points in a plane that are at a specific distance from the centre point. In other words, it is the path a moving point in a plane takes to move around a curve while maintaining a constant distance from another point.

From the figure, we can see that the radius of the circle, the distance from the centre of the circle to the boundary is 2 units.

The area of the circle = πr²

where π is a constant with an approximate value of 3.14 and r is the radius of the circle.

Now substituting the value of r of the given circle in the area equation, we get,

the area of given circle = π * 2² = 3.14 * 4 = 12.56 unit²

Therefore the area of the given circle is 12.56 unit²and, not 3.5 unit² which Bard claims to be.

There are 2002 groups of 5 people that can answer the 5 phone lines.

This is a combination problem, because we want to choose groups of 5 people from a group of 14, and the order in which we choose the people does not matter.

The formula for the number of combinations of n objects taken r at a time is:

C(n,r) = n! / (r! * (n-r)!)

In this case, we want to choose 5 people out of a group of 14, so we can plug those values into the formula:

C(14,5) = 14! / (5! * (14-5)!)

Simplifying the factorial terms:

C(14,5) = (1413121110) / (54321)

C(14,5) = 2002

Answer: In a right-angled triangle, we can use the Pythagorean Theorem to find the length of the remaining side. The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the length of side BC can be found using the Pythagorean Theorem:

BC^2 = AB^2 + AC^2

BC^2 = 10.5^2 + 5.2^2

BC^2 = 110.25 + 27.04

BC^2 = 137.29

BC = √137.29

BC ≈ 11.68 m

Now that we have the length of side BC, we can use the inverse cosine function (cos^-1) to find the angle ∠CBA:

∠CBA = cos^-1 (BC / AB)

∠CBA = cos^-1 (11.68 / 10.5)

∠CBA ≈ 68.194°

Rounding to 3 significant figures, the answer is ∠CBA = 68.2°.

All three cities have the same transformed sine wave, but with different amplitude, period, phase shift, and midline shift values.

A sine wave is a mathematical function that depicts an oscillation that is smooth and repeated. It exists in nature and is useful in many disciplines of research and engineering. It is also employed in a variety of electrical signals, including alternating current (AC).

In the given question,

City 1: Miami

f(x) = 0.48 sin(0.27(x-1.5)) + 0.77

The parent function f(x) = sin(x) has been transformed in several ways, such as the amplitude being changed from 1 to 0.48, the period being changed from 2π to 0.27π, the phase shift being changed from 0 to 1.5, and the midline being shifted up by 0.77. This means that the function is shifted up from the midline of the parent function.

City 2: Honolulu

f(x) = 0.24 sin(0.13(x+1.25)) + 0.86

The parent function f(x) = sin(x) has been transformed in several ways, such as the amplitude being changed from 1 to 0.24, the period being changed from 2π to 0.13π, the phase shift being changed from 0 to 1.25, the midline being shifted up by 0.86, meaning the function is shifted up from the midline of the parent function.

City 3: Austin

f(x) = 0.41 sin(0.21(x-1)) + 0.86

The parent function f(x) = sin(x) has been transformed in several ways, such as the amplitude being changed from 1 to 0.41, the period being changed from 2π to 0.21π, the phase shift being changed from 0 to 1, and the midline being shifted up by 0.86. This means that the function is shifted up from the midline of the parent function.

According to the data supplied, all three cities appear to have the same converted sine wave, but with distinct amplitude, period, phase shift, and midline shift values.

The degree of a vertex represents the number of other actors or actresses that an actor or actress has worked with in movies.

The neighborhood of a vertex represents the set of actors or actresses that an actor or actress has worked with in movies.

Isolated vertices represent actors or actresses who have not worked with any other actors or actresses in any movie, while pendant vertices represent actors or actresses who have only appeared in one movie with another actor or actress in the Hollywood graph.

The Hollywood graph is an undirected graph because the relationship between actors and actresses is mutual.

Each vertex in this graph represents an actor or actress, and the degree of a vertex represents the number of other actors or actresses that they have worked with in movies. In other words, the degree of a vertex represents the number of edges that are connected to that vertex.

The neighborhood of a vertex in a graph refers to the set of all vertices that are adjacent to it. In the context of the Hollywood graph, the neighborhood of a vertex represents the set of actors or actresses that a particular actor or actress has worked with in movies.

An isolated vertex in a graph is a vertex that has no edges connected to it. In the context of the Hollywood graph, an isolated vertex represents an actor or actress who has not worked with any other actors or actresses in any movie.

Answer:

Step-by-step explanation:

To calculate the final account balance for a savings account with an initial deposit of $5,460.75, compounded semiannually with an interest rate of 3.92%, for 51 months, we need to use the formula:

A = P * (1 + r/n)^(nt)

where A is the final account balance, P is the initial deposit, r is the interest rate (as a decimal), n is the number of times the interest is compounded in a year, t is the number of years, and nt is the number of compounding periods.

In this case, n = 2 (since the interest is compounded semiannually), r = 3.92%/100 = 0.0392, t = 51 months / 12 months/year = 4.25 years, and nt = 2 * 4.25 = 8.5.

Substituting the values into the formula, we get:

A = $5,460.75 * (1 + 0.0392/2) ^ (8.5)

A = $5,460.75 * 1.0196^8.5

A = $5,460.75 * 1.2408

A = $6790.32

So, the final account balance if the initial deposit is invested with interest compounded semiannually is $6790.32.

B) Comparing the final account balance of the simple interest account and the compound interest account, we can see that the compound interest account yields a higher balance ($6790.32) than the simple interest account ($6370.51). This is because compounding interest allows for the interest earned in one period to be reinvested, so the interest earns interest in future periods, which increases the overall amount of interest earned over time. In contrast, simple interest is calculated only on the initial deposit, so the amount of interest earned remains constant over time.

After adding and subtracting the rational expressions , the simplified rational expression is 4x - 4/x² - 5/x³ + 9  .

We first simplify each expression inside the parentheses :

that means :

⇒ (2x + 5/x² -3x) = (2x - 3x + 5/x²) = (-x + 5/x²) ;

⇒ (3x + 5/x³ - 9x) = (-6x + 5/x³)  ;

⇒ (x + 1/x² - 9) = (-9 + x + 1/x²)  ;

Now we substitute these expressions into original equation/expression :

we get ; (-x + 5/x²) - (-6x + 5/x³) - (-9 + x + 1/x²)

Simplifying further ,

we get ;

⇒ -x + 5/x² + 6x - 5/x³ + 9 - x - 1/x²  ;

On Combining the like terms, we get ;

⇒ 4x - 4/x² - 5/x³ + 9

The area of Norway's is 24% more than the area of Colorado.So, the area of Colorado is approximately 260,449 square kilometers.

What is Area?

Area is a measurement of the amount of two-dimensional space occupied by a surface or an object. In mathematics, area is a scalar quantity that describes the size of a region in a plane. The units of area are typically square units, such as square meters, square centimeters, square inches, etc.

The formula for the area of a shape depends on the shape itself. For example, the area of a rectangle is equal to its length multiplied by its width, while the area of a circle is equal to π times the square of its radius. Other common shapes and their area formulas include triangles, parallelograms, and trapezoids.

Let's call the area of Colorado "x". If Norway's area is 24% more than Colorado, then Norway's area can be represented as x + 0.24x = 1.24x.

To find the area of Colorado, we can set up an equation:

1.24x = area of Norway

x = area of Norway / 1.24

The area of Norway is 323,802 square kilometers. Therefore, the area of Colorado can be calculated as:

x = 323,802 / 1.24

x = 260,449 square kilometers

So, the area of Colorado is approximately 260,449 square kilometers.

If after the second hour, the increase in ticket sales every hour was 20 more than the increase of the previous hour, it will take 12 hours to sell 10,000 tickets for the Boulders concert.

To solve this problem, we need to find the number of hours it will take to sell 10,000 tickets for the concert. We are given the number of tickets sold in the first three hours and the rate at which ticket sales increase each hour after the second hour.

Let's denote the number of tickets sold in the fourth hour by "x". Then, the number of tickets sold in the fifth hour will be "x + 20", and the number of tickets sold in the sixth hour will be "x + 40", and so on.

Using this information, we can set up an equation to find "x":

500 + 560 + x + (x + 20) + (x + 40) + ... = 10,000

Simplifying the equation, we get:

3x + 1020 + 20n = 9500

where "n" is the number of hours after the third hour.

Solving for "n", we get:

n = (10,000 - 1020 - 3x) / 20

Now, we need to find the value of "x" that satisfies this equation. We can do this by testing different values of "x" until we find the one that gives an integer value for "n".

Let's start by trying "x = 640 + 20 = 660". Plugging this value into the equation, we get:

n = (10,000 - 1020 - 3(660)) / 20 = 9

We arrived at this solution by using the given information about the rate of increase in ticket sales and setting up an equation to solve for the number of hours it will take to sell 10,000 tickets. We then tested different values of "x" until we found the one that satisfied the equation and gave an integer value for "n".
