what is the answer of 1/4+1/5+1/6=​

Answer:

Step-by-step explanation:

total capacity = 62.5 GB

available capacity = 35.0 GB

35 is what percent of 62.5

35 = x% * 62.5

35 / 62.5 = x%

0.56 = x%

56% = x <=====

56% of the memory capacity is still available.

To calculate the percentage of memory capacity that is still available, we can use the available capacity and total capacity information provided.

Given:

Capacity: 62.5 GB

Available: 35.0 GB

To find the percentage, we divide the available capacity by the total capacity and multiply by 100:

Percentage = (Available / Capacity) x 100

Percentage = (35.0 GB / 62.5 GB) x 100

Percentage ≈ 56%

Therefore, 56% of the memory capacity is still available.

Final answer:

The sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree, given a 50-foot tree and a 9-foot shadow, is approximately 0.984, calculated using the definition of sine in a right triangle and the Pythagorean theorem.

Explanation:

The question involves finding the sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree, given that a 50-foot tree casts a 9-foot long shadow. In this scenario, we can visualize a right triangle where the tree represents the opposite side (height), the shadow represents the adjacent side (base), and the hypotenuse is the line from the top of the tree to the end of the shadow on the ground.

To find the sine of the angle, we use the definition of sine in a right triangle, which is sine(angle) = opposite / hypotenuse. However, before we can do that, we need to determine the length of the hypotenuse using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

Let's calculate:

a (opposite) = 50 feet (Height of the tree)

b (adjacent) = 9 feet (Length of the shadow)

c (hypotenuse) = √(50² + 9²) = √(2500 + 81) = √2581 = 50.8 feet (approximately)

Now, we can calculate the sine of the angle:

sine(angle) = opposite / hypotenuse = 50 / 50.8 ≈ 0.984

Therefore, the sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree is approximately 0.984.

Step-by-step  explanation:

By calculating the shipping fees for regular and rush delivery for a 26.5 pound computer, we find that regular shipping saves approximately 14.90 dollars.

We must first calculate the fee for each method and then subtract the regular "shipping fee" from the rush delivery fee to find the savings.

Using the given expression, the regular shipping fee for a 26.5 pound computer is: 0.5*26.5 + 4.49 = 17.74 dollars. Meanwhile, the rush delivery fee for the same computer, using the other given expression, would be: 0.99*26.5 + 6.49 = 32.635 dollars.

Subtracting the regular fee from the rush fee, we find: 32.635 - 17.74 = 14.895 dollars. Therefore, you save about 14.90 dollars by choosing regular shipping over rush delivery.

Answer:

The migration of the African-Americans to Harlem in the USA empowered the African-Americans in the society in the early 1900s. This was one of the greatest accomplishments of the African-Americans in history.

Explanation:

The "Harlem Renaissance" was originally called the "New Negro Movement." During the "Reconstruction Era," many of the African Americans felt a newfound empowerment in the society. They started leaving the South, where most of them were enslaved and maltreated. Many of them moved to other places such as "Harlem" in New York City. It became an ideal destination for many "Negros" and their number increased over time. This then became an African-American neighborhood.

African-Americans started producing plays with actors of their descent. Several Negro poets emerged describing the life of the African-Americans. Negros became more literate and able when it comes to expressing themselves in the society. They even had their own newspaper known as "The New Negro Movement."

Answer:

Frosts second mile and steadys 6th mike

Step-by-step explanation:

Part A: The two plans will cost the same amount when the distance to the airport is 12 miles.

Part B: For a 20-mile distance, Mr. Gardner should choose Fost Shuttle, costing $10 compared to $12 for Steady Shuttle.

Let's solve Part A first:

Part A:

Let's denote the distance to the airport as d miles.

For Fost Shuttle:

Cost = Pick-up fee + Cost per mile × Distance

Cost = $5 + $0.25 × d

For Steady Shuttle:

Cost = Pick-up fee + Cost per mile × Distance

Cost = $2 + $0.50 × d

Now, we'll set up an equation to find when the two plans cost the same amount:

[tex]\[5 + 0.25d = 2 + 0.50d\][/tex]

Solving for d:

[tex]\[0.25d - 0.50d = 2 - 5\]\[-0.25d = -3\]\[d = \frac{-3}{-0.25}\]\[d = 12\][/tex]

So, the two plans will cost the same amount when the distance is 12 miles.

For Part B:

Given the distance is 20 miles, let's calculate the cost for each company:

For Fost Shuttle:

Cost = $5 + $0.25 × 20 = $5 + $5 = $10

For Steady Shuttle:

Cost = $2 + $0.50 × 20 = $2 + $10 = $12

Comparing the costs, Mr. Gardner should choose Fost Shuttle as it costs $10 compared to $12 for Steady Shuttle.

The correct answer is: When triangle ABC is translated 2 units to the left and 1 unit down to create triangle A'B'C' , the coordinates for B' are (-1, 0). The true statement is D.

Let's analyze each statement:

A; When triangle ABC is reflected over the y-axis to create triangle A'B'C' , the coordinates for B' are (1, -1) .

To reflect over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. If the coordinates for B are (x, y), then after reflecting, the x-coordinate becomes -x. Since B has coordinates (1, 1), after reflection, B' will have coordinates (-1, 1). So, statement A is false.

B; When triangle ABC is rotated 90 degrees clockwise about point A to create triangle A'B'C' , the coordinates for B' are (3,3]

Rotation of 90 degrees clockwise about a point involves swapping x and y coordinates and negating the new x-coordinate. The point A is not given, but assuming it's (0, 0), if B has coordinates (x, y), then after rotation, B' will have coordinates (y, -x). If A is (0, 0) and B is (3, 1), after rotation, B' will have coordinates (1, -3), not (3, 3). So, statement B is false.

C; When triangle ABC is dilated from the origin by a scale factor of 1/4 to create triangle A'B'C', the coordinates for B' are (4,4)

Dilating by a scale factor of 1/4 means multiplying each coordinate by 1/4. If B has coordinates (x, y), then after dilation, B' will have coordinates (1/4 * x, 1/4 * y). Since B has coordinates (4, 4), after dilation, B' will have coordinates (1, 1). So, statement C is false.

D; When triangle ABC is translated 2 units to the left and 1 unit down to create triangle A'B'C' , the coordinates for B' are (-1, 0)

Translation involves adding/subtracting values to x and y coordinates. If B has coordinates (x, y), then after translation by (-2, -1), B' will have coordinates (x - 2, y - 1). Since B has coordinates (1, 1), after translation, B' will have coordinates (-1, 0). So, statement D is true.

E; When triangle ABC is dilated from the origin by a scale factor of 5 to create triangle A'B'C', the coordinates for B' are (5,5)

Dilating by a scale factor of 5 means multiplying each coordinate by 5. If B has coordinates (x, y), then after dilation, B' will have coordinates (5 * x, 5 * y). Since B has coordinates (4, 4), after dilation, B' will have coordinates (20, 20), not (5, 5). So, statement E is false.

So, the true statement is D.

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

26) If f(x) = cos (2x) , find f(3π/4).

Substitute with x = 3π/4

f(3π/4) = cos ( 2 * 3π/4) = cos ( 3π/2) = zero.

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

27) If f(x) = sin (2x) + cos (3x) , find f(π/4)

Substitute with x = π/4

f(π/4) = sin ( 2 * π/4) + cos ( 3 * π/4) =

        = sin ( π/2) + cos ( 3π/4)

        =  1  - 1/(√2)

        = 0.293

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

28) f(x) = tan (5x) - sin (2x) , find f(π/6).

Substitute with x = π/6

So, f(π/6) = tan (5 * π/6) - sin ( 2 * π/6)

               = tan (5π/6) - sin (π/3)

               = -1/(√3) - (√3)/2

Answer:

x = 9

Step-by-step explanation:

Determine the defined range

[tex]log^6 (4x^2) - log^6 (x) = 2, x = (0, + ∞)[/tex]

Use log^a (x) - log^a (y) = log^a (x/y) to simplify the expression

[tex]log6 (\frac{4x^{2} }{x} )= 2[/tex]

Simplify the expression

log^6 (4x) = 2

Convert the logarithm into an exponential form using the fact that log^a (x) = b is equal to x = a^b

[tex]4x=6^{2}[/tex]

Evaluate the power

4x = 36

Divide both sides of the equation by 4

x = 9, x = (0, + ∞)

Check if the solution is the defined range
