In the scale drawing, what is the area of the lawn (that is, the area of the whole backyard, except for the deck)?

Answers

Answer 1

The area of the lawn in the scale drawing is approximately 996 square feet.

1. Measure the length and width of the lawn in inches on the scale drawing.

Length = 16.5 inches

Width = 15.5 inches

2. Convert the measurements to feet by dividing the inches by 12.

Length = 16.5/12 = 1.375 feet

Width = 15.5/12 = 1.291 feet

3. Calculate the area of the lawn by multiplying the length and width.

Area = 1.375 x 1.291 = 1.75 square feet

4. Multiply the area by the scale factor (in this case, 560) to get the actual area.

Area = 1.75 x 560 = 996 square feet

Reflection Paper on "Freedom Riders" Documentary

The "Freedom Riders" is a powerful documentary that recounts the story of a group of civil rights activists who rode buses across the American South in 1961 to challenge the segregated public transportation system. The film provides a vivid and moving account of their journey and the challenges they faced along the way, from beatings and arrests to bombings and arson attacks. Through interviews with surviving freedom riders and archival footage, the film sheds light on the bravery and determination of these activists and the impact they had on the civil rights movement.

The freedom riders were inspired by the nonviolent protest movement led by Dr. Martin Luther King Jr. and other civil rights leaders. They believed that segregation was a moral wrong and that they had a duty to resist it through nonviolent means. Despite the danger they faced, the freedom riders refused to back down, putting their lives on the line for the cause of justice and equality.

The bravery of the freedom riders had a profound impact on the civil rights movement. Their actions galvanized support for the cause and drew national attention to the issue of segregation. The freedom rides sparked a wave of protests and civil disobedience across the South, and helped to build momentum for the passage of the Civil Rights Act of 1964. This landmark legislation banned segregation in public places and made it illegal to discriminate against someone on the basis of race, color, religion, sex, or national origin.

The "Freedom Riders" documentary serves as a powerful reminder of the sacrifices made by those who fought for civil rights in the United States. It highlights the courage and determination of the freedom riders and the impact they had on the country. It is an important film that teaches us about the past and the struggles of those who fought for justice and equality.

In conclusion, the "Freedom Riders" documentary is a powerful reminder of the sacrifices made by those who fought for civil rights in the United States. It highlights the bravery and determination of the freedom riders and the impact they had on the civil rights movement. The film serves as a testament to the power of nonviolent protest and the importance of standing up for what is right, even in the face of opposition. The lessons of the freedom riders should inspire us all to continue working towards a more just and equal society.

3cos²∅ (1+tan²∅) = 3

This equation involves trigonometric functions and can be simplified using trigonometric identities.

Starting with the right-hand side of the equation, we have 3. On the left-hand side, we have the expression 3cos^2(θ)(1 + tan^2(θ)).

We can simplify the expression as follows:

cos^2(θ) = 1 - sin^2(θ)

and

tan^2(θ) = sin^2(θ) / cos^2(θ)

Substituting these identities into the expression on the left-hand side, we get:

3(1 - sin^2(θ))(1 + sin^2(θ) / (1 - sin^2(θ))

Expanding the product and simplifying, we get:

3

Thus, the equation is true and holds true for all values of θ.

Bob buys a big bag of beans for $2. 37. Find x, the number of dollars he gave the cashier if he received $17. 63 in change

Answers

Bob gave the cashier $15.26 for the bag of beans.

To find the value of x, we need to subtract the cost of the beans from the total amount given to the cashier. The cost of the beans is $2.37, and the change received is $17.63.

Therefore, the value of x can be calculated as:

x = Total amount given to the cashier - Cost of the beans

x = $17.63 - $2.37

x = $15.26

classify each peptide chain as part of a parallel β sheet, part of an antiparallel β sheet, either type of β sheet, or not part of a β sheet.

Answers

The first figure represents Antiparallel β sheet. Second figure is parallel β sheet. Third figure represents neither of the two types. The fourth figure is also parallel β sheet and the fifth figure represents both types.

Antiparallel and parallel β-sheets are two different arrangements of the β-strands in a protein structure.

In an antiparallel β-sheet, the direction of the peptide bonds in the individual β-strands is opposed to each other, meaning that the N-terminal end of one strand points in the opposite direction from the N-terminal end of the neighboring strand. The hydrogen bonds between the strands run perpendicular to the direction of the peptide bonds and hold the strands together.

In a parallel β-sheet, the direction of the peptide bonds in the individual β-strands is the same, meaning that the N-terminal end of one strand points in the same direction as the N-terminal end of the neighboring strand. The hydrogen bonds between the strands run parallel to the direction of the peptide bonds and hold the strands together.

Both antiparallel and parallel β-sheets play important roles in the structure and function of proteins, and are found in many different types of proteins, including enzymes, transport proteins, and structural proteins.

Find the distance travelled by rahul, if he takes 6 rounds of a square field of side=120m

Answers

The distance travelled by Rahul, if he takes 6 rounds of a square field of side = 120m is 2880 meters.

We are given that Rahul takes 6 rounds of a square field of side length 120m. To find the total distance he travels, we need to calculate the perimeter of the square field and multiply it by the number of rounds.

The perimeter of a square is the sum of the lengths of its four sides. Since the side length of the square field is 120m, the perimeter is:

4 * 120m = 480m

This is the distance Rahul covers in one round around the square field.

To find the total distance he covers in 6 rounds, we multiply the distance covered in one round by the number of rounds:

480m * 6 = 2880m

So, Rahul covers a total distance of 2880 meters.

Find the total wingspan

Answers

Answer:

9.9 cm

Step-by-step explanation:

The right triangle has one-half the wing span as a leg.

The hypotenuse is 5.8cm and the other leg is 3cm

If we let the unknown leg of the triangle be x, by the Pythagorean theorem we know the sum of the squares of the two legs must be equal to the square of the hypotenuse .

So

x² + 3² = 5.8²

x² = 5.8² - 3²

= 33.64-9

= 24.64

x = √24.64

= 4.96

Total wingspan = 4.96 × 2 = 9.9 cm

The expression [2³ x (225 +9)] - 33 can be simplified to 2³ x 234 - 33. To evaluate this expression, we can begin by calculating 2³ x 234. 2³ is equal to 8, so 8 x 234 = 1872. Subtracting 33 from 1872 gives us a result of 1839. Therefore, the expression [2³ x (225 +9)] - 33 can be simplified to 1839.

(recall that the bucket is being lifted at a constant rate, as well.) (5pts)

Answers

If the weight of the bucket is 70 lb , then the work required to lift the bucket from bottom is 135240 foot-pounds  .

We use the formula : Work = Force × Distance to calculate the work done

where "Force" is weight of bucket filled with water and "Distance" is  height it is lifted.

The weight of bucket filled with water is =  70 pounds.

We convert this to a force in pounds force, by using g = 32.2 feet per second squared ;

So , Force = Weight × Gravity

⇒ 70 lb × 32.2 ft/s² = 2254 lb-ft/s²

The distance that the bucket is lifted is = 60 feet ;

So , work required to lift bucket from bottom of well to top is :

⇒  Work = Force × Distance = 2254 lb-ft/s² × 60 ft

⇒ 135240 foot-pounds

Therefore , it will require 135240 foot-pounds of work to lift the bucket filled with water from the bottom of the well to the top.

Describe how the volume of three tennis balls, each with a diameter of 2.7​​ inches compares to the volume of their packaging, which is a cylinder that has the same diameter and a height of 8.1 inches. Explain or show your work.

Answers

Answer:

Step-by-step explanation:

The volume of the three tennis balls combined is approximately 4.88 cubic inches. The volume of the packaging cylinder is approximately 50.33 cubic inches. Thus, the volume of the three tennis balls is about 9.7% of the volume of their packaging cylinder.

To calculate this, we can use the formula for the volume of a sphere (V = 4/3 x π x r3) and the formula for the volume of a cylinder (V = π x r2 x h).

The radius of each tennis ball is half the diameter, or 1.35 inches. So, the volume of each tennis ball is 4/3 x π x (1.35)3 = 4.88 cubic inches.

The radius of the cylinder is the same as the diameter of each tennis ball, or 2.7 inches. The height of the cylinder is 8.1 inches. So, the volume of the cylinder is π x (2.7)2 x 8.1 = 50.33 cubic inches.

The volume of the three tennis balls is 4.88 x 3 = 14.64 cubic inches. The volume of the packaging cylinder is 50.33 cubic inches. Thus, the volume of the three tennis balls is 14.64 ÷ 50.33 = 0.097 = 9.7% of the volume of their packaging cylinder.

The mean would be 35 feet.

The mean tells us that the typical throw of the ball results in a distance of approximately 3.5 feet.

what is Mean?

In arithmetic, mean is the sum of all the added values of all the data in a set divided by the number of data in the set.

To find the mean of the distances, we need to calculate the sum of all the distances and divide by the total number of distances:

(20+25+25+31+33+34+41+41+45+50+56+67) / 12 = 425 / 12 = 35.42

Rounding to one decimal place, we get the mean distance of approximately 3.5 feet.

However, it's worth noting that the stem-and-leaf plot shows some variability in the distances, with some throws going as far as 6.7 feet and some as short as 2 feet.

So while the mean can provide us with a measure of central tendency, it doesn't tell the whole story about the distribution of the distances.

b) Calculate the angle of elevation to one decimal place. Tan x= opposite/adjacent
c) Calculate the percent grade to one decimal place. Percent Grade slope X 100

Answers

a) To calculate the slope, we divide the change in elevation by the horizontal distance:

870 m / 8154 m = 0.1065

So, the slope is 0.107 to three decimal places.

b) To calculate the angle of elevation, we use the tangent formula:

Tan x = opposite / adjacent = 870 m / 8154 m = 0.1065

So, x = tan^-1(0.1065) = 6.08°

The angle of elevation to one decimal place is 6.1°.

c) To calculate the percent grade, we multiply the slope by 100:

Percent grade = slope x 100 = 0.1065 x 100 = 10.7%

So, the percent grade to one decimal place is 10.7%.

where n is the required sample size, z is the critical value for the desired confidence level (95% confidence level corresponds to a z-value of 1.96), σ is the population standard deviation (given as the square root of the variance, which is √(70) ≈ 8.37), and E is the maximum error, or the maximum difference between the sample mean and population mean that we are willing to tolerate (which is given as 2.5 units).

Substituting the given values into the formula, we get:

n = [ (1.96 * 8.37) / 2.5 ]^2

n ≈ 43.48

Rounding up to the nearest whole number, we get a required sample size of n = 44.

Therefore, a sample size of 44 is needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units, assuming a normal distribution with a population variance of 70.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The roots of the quadratic equation are -

HCF of smallest prime number, LCM of smallest composite number

The smallest prime number is 2.

So, the HCF of 2 is 2.

The smallest composite number is 4.

So, the LCM of 4 is 4.

If m and n are the roots of a quadratic equation ax² + bx + c = 0, then the sum of the roots is (m+n) and the product of the roots is (mn).

And then the quadratic equation becomes x² - (m+n)x +mn = 0.

So, here m = 2 and n = 4.

The sum of roots is -

(m + n) = (2 + 4) = 6

The product of roots is -

(mn) = (2 × 4) = 8

So, the quadratic equation is x² - 6x +8 = 0.

Therefore, the equation is x² - 6x +8 = 0.

A. The line for y=-2x+1 will be solid.
B. Shading will be below the y=-2x+ 1 line and below the y= 3x - 1
line.
C. Shading will be above the y=-2x+1 line but below the y= 3x-1
line.
D. None of the above
SUBMIT

Answers

Answer:

Step-by-step explanation:

The correct answer is C. Shading will be above the y=-2x+1 line but below the y= 3x-1 line.

The line y=-2x+1 is a line with a slope of -2 and a y-intercept of 1. It represents the solutions that are greater than -2x+1.

The line y=3x-1 is a line with a slope of 3 and a y-intercept of -1. It represents the solutions that are less than 3x-1.

So, when you graph both of these lines on the same coordinate plane, the solutions that satisfy both inequalities will be the region that is above the line y=-2x+1 but below the line y=3x-1, and this is the region that will be shaded.

Angle QRS is an equilateral triangle. If QR is seven less than twice x, RS is 61 less than five times x, and QS is 11 more than x, find the value of x and the measure of each side

Answers

The value of x is 18 and the measure of each side is:

QR = RS = QS = 29

What is called equilateral?

An equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.

Now, According to the question:

Angle QRS is an equilateral triangle.

QRS is an equilateral triangle, thus all the three sides of the given triangle will be equal.

we have

QR = 2x - 7___(1)

RS = 5x - 61 ___(2)

QS = 11 + x_____(3)

Now, As all the sides of the triangle are equal, therefore

QR = RS = QS

⇒QR = RS

⇒2x - 7 = 5x - 61

⇒ -7 + 61 = 5x - 2x

⇒ 54 = 3x

⇒ x = 18

Put the value of x in above equations:

Thus, the measure of

QR = 2(18) - 7=29,

RS = 5(18) - 61 = 29 and

QS = 11 + 18 = 29.

suzy borrows $4500 and agrees to repay it all in equal monthly instalments over 3 years. Simple interest at 7.2% p.a is charged on a loan. find the amount of each instalment

Answers

The amount of Suzy's instalment every month if it is agreed to repay equal amount monthly is $152

What is the amount of each instalment?

Simple interest = principal × rate × time

= 4500 × 0.072 × 3

= $972

Total amount to repay = $4500 + $972

= $5472

Repayment time = 3 years

Suzy will repay every month

3 years= 12 months × 3

= 36 months

Since,

the repayment is equal every month

Amount of instalment every month= $5472 / 36

= $152

Therefore, Suzy will repay $152 each month instalmentally.
