Step-by-step explanation:

The total distance covered by Edwin in duration of 3 hours and 30 minutes at a speed of 70km per hour  is equal to 245 kilometers.

Use the formula,

distance = speed x time

To find the distance Edwin covers in 3 hours and 30 minutes.

First, convert 3 hours and 30 minutes to hours.

1 hour is equal to 60 minutes, so,

This implies,

3 hours and 30 minutes

= 3 + 30/60

= 3.5 hours

Now apply the formula we have,

distance = speed x time

⇒ distance = 70 km/h x 3.5 h

⇒ distance = 245 kilometers

Therefore, distance covered by Edwin will be 245 kilometers in 3 hours and 30 minutes, if he drives at a speed of 70 km/h.

Using Pythagorean theorem, the perimeter of the plot of land is 1783/16 feet.

What is the Pythagorean theorem?

The Pythagorean theorem is a fundamental mathematical concept that outlines the relationship between a right triangle's three sides. It states that the square of the hypotenuse's (triangle's longest side) length equals the sum of the squares of the other two sides (the legs).

The Pythagorean theorem can be expressed numerically as follows:

a² + b² = c²

Let x= length of the shorter leg. Then, using the given ratio, the length of the hypotenuse can be expressed as 16x/65.

By the Pythagorean theorem, we have:

x² + 189² = (16x/65)²

Simplifying this equation, we get:

4225x² + 189² * 65² = 16² * x²

Solving for x, we get:

x = 315/4

Therefore, the perimeter is

189 + 315/4 + √(189² + (16/65)² * 315²/16)

Simplifying this expression, we get:

189 + 315/4 + 243/4 = 207/4 + √(2134441/256)

207/4 + 1463/16 = 1783/16

Therefore, the perimeter of the plot of land will be  1783/16 feet.

To enlarge Shape A by a scale factor of 1.5 with the center of enlargement (0, 0), we have to multiply every length by 1.5.

Enlargement of Shape A

Enlargement of a shape is when it is either stretched or shrunk in one or both directions. The original shape is called the pre-image, while the new shape is called the image. What is the centre of enlargement?

The center of an enlargement is the point about which all of the points of the pre-image are scaled to obtain the image. When the scale factor is greater than 1, the image of the pre-image is an enlargement. When the scale factor is between 0 and 1, the image of the pre-image is a reduction.In an enlargement, each point on the pre-image is mapped onto a corresponding point on the image along a straight line which goes through the centre of enlargement.

The new shape has a larger size than the original shape. To expand shape A by a scale factor of 1.5, you need to multiply each length by 1.5. You have to create new points. It's easy to use a scale ruler to make sure each length is multiplied by 1.5.

A Centre of enlargement is a point in the coordinate plane that enlarges or shrinks a figure by some scale factor. In the problem, the center of enlargement is (0, 0).

Thus, we have to extend every length of Shape A by 1.5, and our scale factor is 1.5. We get Shape B by doing so. Now, we can conclude that to enlarge Shape A by a scale factor of 1.5 with the center of enlargement (0, 0), we have to multiply every length by 1.5.

Latrell would need to pay 105 to replace the felt on his pool table.

Latrell has a pool table that is 3 feet wide and 7 feet long.

The pool table's felt needs to be replaced, and the cost of the felt per square foot is $5.00.

Let's find out how much it would cost Latrell to replace the pool table's felt.

What is the surface area of the pool table.

To determine the surface area of the pool table,

we need to multiply the length by the width, as shown below:

Surface area = length × width

Surface area = 7 ft × 3 ft

Surface area = 21 square feet

Now that we know the surface area of the pool table, we can determine the cost of the felt.

Latrell will need 21 square feet of felt, and it costs $5.00 per square foot.

We can use the following formula to determine the total cost of the felt:

Total cost of felt = cost per square foot × surface area.

Total cost of felt = $5.00 × 21 square feet.

Total cost of felt = $105

The z-score for a raw score of 12 in a distribution with a mean of 6 and a standard deviation of 3 is 2.

The z-score is a measure of how many standard deviations a raw score is above or below the mean of a distribution. It is calculated by subtracting the mean from the raw score and then dividing the result by the standard deviation.

In this case, we have a mean of 6 and a standard deviation of 3. To find the z-score for a raw score of 12, we can use the formula:

z = (x - μ) / σ

where x is the raw score, μ is the mean, and σ is the standard deviation.

Substituting the values we have, we get:

z = (12 - 6) / 3 = 2

Therefore, the z-score for a raw score of 12 in this distribution is 2. This means that the raw score of 12 is 2 standard deviations above the mean of 6. The z-score can be used to compare scores from different distributions, and to calculate probabilities and percentiles.

The value of x is approximately 8.15.

To find the value of x, we need to use the formula for the volume of a cone, which is V = (1/3)πr^2h, where r is the

radius of the base and h is the height of the cone. We know that the volume of the cone below is 392π, so we can set

up the equation:

[tex]392π = (1/3)πx^2h[/tex]

Simplifying, we can divide both sides by π and multiply by 3 to get:

[tex]1176 = x^2h[/tex]

Using the Pythagorean theorem, we can relate the height, radius, and slant height of the cone:

[tex]h^2 + r^2 = x^2[/tex]

Since the cone is a right cone, we know that the radius is half of the diameter, which is equal to x/2. Substituting this in,

we get:

[tex]h^2 + (x/2)^2 = x^2[/tex]

Simplifying:

[tex]h^2 = x^2 - (x/2)^2

h^2 = 3x^2/4[/tex]

Now we can substitute this expression for [tex]h^2[/tex] into our equation for the volume:

[tex]1176 = x^2(3x^2/4)[/tex]

Simplifying again:

[tex]1176 = 3x^4/4[/tex]

[tex]1568 = 3x^4[/tex]

[tex]x^4 = 1568/3[/tex]

Let's assume that each van and each bus can carry "x" number of students.

Let's assume there are "x" students in each van and each bus. Therefore, the total number of students in High School A's senior class is 8x + 8x = 16x. We know that the total number of students in High School A's senior class is 240, so we can set up an equation:

16x = 240

Solving for x, we get:

x = 15

So, each van and each bus had 15 students in it for High School A's senior class.

Similarly, for High School B, the total number of students is 4x + 1x = 5x. We know that the total number of students in High School B's senior class is 54, so we can set up an equation:

5x = 54

Solving for x, we get:

x = 10.8

Since the number of students must be a whole number, we can round up to 11. Therefore, each van and each bus had 11 students in it for High School B's senior class.

Therefore, the total number of students in High School A's senior class is 1x + 6x = 7x. We know that the total number of students in High School A's senior class is 372, so we can set up an equation:

7x = 372

Solving for x, we get:

x = 53

Therefore, each van and each bus can carry 53 students for High School A's senior class.

Similarly, for High School B, the total number of students is 4x + 12x = 16x. We know that the total number of students in High School B's senior class is 780, so we can set up an equation:

16x = 780

Solving for x, we get:

x = 48.75

Since the number of students must be a whole number, we can round up to 49. Therefore, each van and each bus can carry 49 students for High School B's senior class.

Let's assume that the price of one senior citizen ticket is "s" and the price of one child ticket is "c". Therefore, we can set up two equations based on the given information:

[tex]3s + 9c = 75[/tex]

[tex]8s + 5c = 67[/tex]

We can solve these equations simultaneously to find the values of "s" and "c". One way to do this is to multiply the first equation by 8 and the second equation by 3, so that we can eliminate "c" and solve for "s":

[tex]24s + 72c = 600[/tex]

[tex]24s + 15c = 201[/tex]

Subtracting the second equation from the first, we get:

57c = 399

Solving for "c", we get:

c = 7

Substituting this value into one of the original equations, we can solve for "s":

[tex]3s + 9(7) = 75[/tex]

[tex]3s + 63 = 75[/tex]

[tex]3s = 12[/tex]

[tex]s = 4[/tex]

Therefore, one senior citizen ticket costs $4 and one child ticket costs $7.

Answer:

Step-by-step explanation:

Given a^2 + b^3 + c^4 = 55, we need to find the greatest value for a * b * c.

To solve this problem, we can use the AM-GM inequality, which states that the arithmetic mean of a set of non-negative numbers is always greater than or equal to their geometric mean.

Using this inequality, we have:

(a^2 + b^3 + c^4) / 3 >= (a*b*c)^(2/3)

55/3 >= (a*b*c)^(2/3)

(55/3)^(3/2) >= a*b*c

The maximum value of a, b, and c occurs when they are as close together as possible. We can use the fact that a, b, and c are distinct positive integers to determine that the closest they can be is 1, 2, and 3.

So the greatest value for a * b * c is (1*2*3) = 6, and we have:

(55/3)^(3/2) >= 6

Approximately: 23.1 >= 6

Therefore, the greatest value for a * b * c is 6.

The greatest value for abc is 3,240.

We want to find the greatest value of the product abc, given that a, b, and c are different positive integers and a + b + c = 55.

To maximize the value of abc, we want to maximize each individual factor, a, b, and c. We can do this by setting a to be as small as possible and c to be as large as possible, while ensuring that a, b, and c are still different positive integers.

Since a, b, and c are different positive integers, the smallest value for a is 1.

To maximize c, we set b = a + 1 and c = 55 - a - b.

Substituting b and c in terms of a, we get:

c = 55 - a - (a + 1) = 54 - 2a

Now we can express the product abc in terms of a:

abc = a x b x c = a (a + 1)(54 - 2a)

Expanding this expression, we get:

abc = -2a³ + 53a²+ 54a

To find the maximum value of abc, we can take the derivative of this expression with respect to a and set it equal to zero:

d(abc)/da = -6a² + 106a + 54 = 0

Solving for a, we get:

a = 8.93 (rounded to two decimal places)

Since a must be a positive integer, we round up to a = 9.

Using this value of a, we can find the corresponding values of b and c:

b = a + 1 = 10

c = 55 - a - b = 55 - 9 - 10 = 36

Therefore, the greatest value of abc is:

abc = 9 x 10 x 36 = 3,240

Answer:

We can use the compound interest formula to find the total amount of interest Claire will get at the end of four years:

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

Where:

A = the total amount of money in the account at the end of the four years

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = £200000

r = 0.016 (1.6% expressed as a decimal)

n = 1 (compounded annually)

t = 4

So, the formula becomes:

A = £200000(1 + 0.016/1)^(1*4)

= £200000(1.016)^4

= £219,463.18

To find the total amount of interest Claire will get, we need to subtract the principal amount from the total amount of money in the account at the end of four years:

Total interest = £219,463.18 - £200,000

= £19,463.18

Therefore, Claire will get £19,463.18 in total interest at the end of four years.

Answer:

In a right triangle, one of the angles measures 90 degrees, and the other two angles are acute angles that add up to 90 degrees. Let's call the measures of the two acute angles x and y.

We know that x and y differ by 22 degrees. So we can set up an equation:

x - y = 22

We also know that x + y = 90, since the two acute angles add up to 90 degrees.

Now we can solve this system of equations for x and y. One way to do this is to add the two equations together, which eliminates y:

x - y + x + y = 22 + 90

2x = 112

x = 56

Now we can substitute x = 56 into one of the equations to find y:

x + y = 90

56 + y = 90

y = 34

Therefore, the measures of the two acute angles of the right triangle are 56 degrees and 34 degrees.

c. We can determine the pair of numbers that have the largest product by using the following reasoning: For any two numbers whose sum is fixed, their product is maximized when the two numbers are as close together as possible. This is because the product of two numbers that are far apart is always smaller than the product of two numbers that are closer together and have the same sum.

Using area of the rectangle, we can find that the new flower garden will be 13m in length (greater dimension).

The formula for calculating a rectangle's area can be used to determine how much space the rectangle takes up within its perimeter. Multiplying the length by the width yields the area of a rectangle (breadth).

As a result, the following formula can be used to determine the area of a rectangle whose length and breadth are "l" and "w," respectively. The rectangle's area is L × W. A rectangle's area is therefore equal to length * width.

Now here the dimensions of the rectangle are, l = 13m and b, = 9m.

Area of the rectangle is 13 × 9 = 117m².

Now the area of the rectangle is increased to 221m².

So, when we increase the length from 13 m to 17m and the breadth from 9m to 13m, we get area = 17 × 13 = 221m².

Therefore, length of the new garden will be 17m long.

The decision rule is as follows: If Z < -1.96, reject the null hypothesis. If not, fail to reject the null hypothesis.

The decision rule in statistics is a statement that instructs on the null hypothesis’s rejection or acceptance. It is a predetermined criterion used to test a hypothesis. When the calculated test statistic falls outside the critical region, the null hypothesis is rejected. A chocolate chip producer wants to know if the 404.0 gramme setting on their bag-filling machine is correct.

It is suspected that the machine is underfilling the bags. The chocolate chip manufacturer uses a 41 bag sample with an average weight of 396.0 grams to determine whether the machine works correctly at 404.0 gram setting.

With a significance level of 0.05, the decision rule is as follows:

If Z < -1.96, reject the null hypothesis. If not, fail to reject the null hypothesis.

Z can be calculated as follows:

z = (x - μ) / (σ / √n)

where:

x = sample mean = 396.0

μ = population mean = 404.0

σ = standard deviation = 25.0

n = sample size = 41

Substitute the values in the equation:

z = (396.0 - 404.0) / (25.0 / √41)z = -2.67Z < -1.96
