(I) The new selling price per kilogram of the tomatoes is 0.4576.

(II) The percentage profit on the whole transaction is 24.77% if she threw away 5kg of bad tomatoes.

The new selling price is calculated as follows;

The cost per kilogram of the tomatoes is;

Cost per kg = Total cost / Total weight

Cost per kg = 52 / 130

Cost per kg = 0.4

Selling price per kg = Cost per kg + (Profit percentage x Cost per kg)

Selling price per kg = 0.4 + (0.3 x 0.4)

Selling price per kg = 0.52

The new selling price per kilogram is:

= Selling price per kg - (Reduction percentage x Selling price per kg)

= 0.52 - (0.12 x 0.52)

= 0.4576

The total revenue from selling the tomatoes is calculated as;

The woman sold half of the 130kg of tomatoes, = 130 / 2 = 65kg

Revenue = (amount sold x selling price per kg) + (amount left x new selling price per kg)

Revenue = (65 x 0.52) + (65 x 0.4576)

Revenue = 33.8 + 29.68

Revenue = 63.48

New total cost = Total cost / Total weight x (Total weight - Bad tomatoes)

New total cost = 0.4 x (130 - 5)

New total cost = 50.6

The profit on the whole transaction  is calculated as;

Profit = Total revenue - New total cost

Profit = 63.48 - 50.6

Profit = 12.88

The profit percentage on the whole transaction is calculated as;

Profit percentage = (Profit / Total cost) x 100%

Profit percentage = (12.88 / 52) x 100%

Profit percentage = 24.77%

C. The fee at Bank K will always be greater than the fee at Bank F.

This is because for any given average daily balance, Bank K has a higher fee than Bank F. For example, for an average daily balance of less than $500, Bank F charges $8 while Bank K charges $12. Similarly, for an average daily balance between $500 and $750, Bank F charges no fee while Bank K charges $12. Therefore, the fee at Bank K will always be greater than the fee at Bank F.

The class will use 20 yards of the 50-yard spool, leaving 30 yards of string leftover.

This leftover string could be used for future projects or saved for another occasion.

Lacey's class will use a total of 720 inches (30 inches per student x 24 students) of string for the candy necklaces.

To convert this to yards, we divide by 36 (since there are 36 inches in a yard). 720 inches ÷ 36 = 20 yards

It's important to note that when working with different units of measurement, it's necessary to convert them to the same unit before performing calculations.

In this case, we converted inches to yards in order to determine the amount of string used by the class. By doing so, we were able to determine how much string was leftover in yards, which is a more appropriate unit of measurement for a spool of string.

Answer:

We know that Miranda ran 4 miles in 28 minutes. Let's set up the proportion:

4 miles / 28 minutes = x miles / 2 minutes

To solve for x, we can cross-multiply:

28 minutes * x miles = 4 miles * 2 minutes

28x = 8

Now, let's solve for x by dividing both sides of the equation by 28:

x = 8 / 28

x = 0.2857

Therefore, Miranda runs approximately 0.2857 miles in 2 minutes.

The perimeter of the triangle formed by joining the midpoints of the sides of the original triangle is 3.

To find the perimeter of the triangle formed by joining the midpoints of the sides of the original triangle, we first need to find the midpoints. The midpoint of a side of a triangle is the point that is exactly halfway between the endpoints of that side.

Using the formula for the midpoint of a line segment ((x1+x2)/2, (y1+y2)/2), we can find the midpoints of the sides with lengths 9, 12, and 15:

Midpoint of the side with length 9: ((9+12)/2, (0+0)/2) = (10.5, 0)

Midpoint of the side with length 12: ((9+15)/2, (0+0)/2) = (12, 0)

Midpoint of the side with length 15: ((12+9)/2, (0+0)/2) = (10.5, 0)

Note that all three midpoints lie on the x-axis.

Now we can find the lengths of the sides of the triangle formed by joining the midpoints. These sides are the line segments connecting the midpoints, and their lengths are equal to the distances between the midpoints:

Length of the side connecting (10.5, 0) and (12, 0):

d = sqrt((12-10.5)^2 + (0-0)^2) = 1.5

Length of the side connecting (10.5, 0) and (10.5, 0):

d = sqrt((10.5-10.5)^2 + (0-0)^2) = 0

Length of the side connecting (12, 0) and (10.5, 0):

d = sqrt((10.5-12)^2 + (0-0)^2) = 1.5

So the triangle formed by joining the midpoints of the sides of the original triangle is an isosceles triangle with two sides of length 1.5 and one side of length 0. The perimeter of this triangle is:

Perimeter = 1.5 + 1.5 + 0 = 3

Therefore, the perimeter of the triangle formed by joining the midpoints of the sides of the original triangle is 3.

The maximum rate of change occurs in the direction of this unit vector.

(a) To find the maximum rate of change of f at point P(1,0), we need to find the gradient of f at that point and then find its magnitude. The direction of maximum increase is given by the unit vector in the direction of the gradient.

The gradient of f is:

∇f(x,y) = <y cos(xy), x cos(xy)>

At point P(1,0), we have:

∇f(1,0) = <0, cos(0)> = <0, 1>

The magnitude of the gradient is:

||∇f(1,0)|| = sqrt([tex]0^2[/tex] +[tex]1^2[/tex]) = 1

Therefore, the maximum rate of change of f at point P is 1, and it occurs in the direction of the unit vector in the direction of the gradient:

u = <0, 1>/1 = <0, 1>

So the maximum rate of change occurs in the y-direction.

(b) To find the maximum rate of change of f at point P(8,1.3), we need to find the gradient of f at that point and then find its magnitude. The direction of maximum increase is given by the unit vector in the direction of the gradient.

The gradient of f is:

∇f(x,y,z) = <2x, 2y, 2z>

At point P(8,1.3), we have:

∇f(8,1.3) = <16, 2.6, 2(1.3)> = <16, 2.6, 2.6>

The magnitude of the gradient is:

||∇f(8,1.3)|| = sqrt[tex](16^2 + 2.6^2 + 2.6^2)[/tex]= sqrt(275.56) ≈ 16.6

Therefore, the maximum rate of change of f at point P is approximately 16.6, and it occurs in the direction of the unit vector in the direction of the gradient:

u = <16, 2.6, 2.6>/16.6 ≈ <0.963, 0.157, 0.157>

The number of miles travelled is 6.2 miles.

What is Kilometer ?

A kilometer (km) is a unit of length or distance measurement in the metric system. It is equivalent to 1,000 meters or approximately 0.62 miles. The prefix "kilo" means "thousand", so one kilometer is equal to 1,000 meters.

Completing the statements:

Kilometers are a larger unit of distance measurement compared to miles. That means the number of kilometers in a distance will always be greater than the number of miles in that distance.

We can convert miles to kilometers by multiplying the number of miles by 1.61. For example, if we have a distance of 5 miles, we can convert it to kilometers as:

5 × 1.61  = 8.05 kilometers

The slope of the line that divides the region into two equal parts is 8/7.

We begin by finding the x-coordinates of the points where the parabola intersects the x-axis. Setting y = 0, we get:

[tex]2x - 7x^2 = 0[/tex]

x(2 − 7x) = 0

x = 0 or x = 2/7

Thus, the parabola intersects the x-axis at x = 0 and x = 2/7.

We want to find the slope of the line through the origin that divides the region bounded by the parabola and the x-axis into two regions with equal area.

Let's call this slope m.

We know that the area under the parabola from x = 0 to x = 2/7 is:

A = ∫[0,2/7] (2x − 7[tex]x^2[/tex]) dx

A = [[tex]x^2[/tex] − (7/3)[tex]x^3[/tex]] from 0 to 2/7

A = (4/21)

Since we want the line to divide this area into two equal parts, the area to the left of the line must be (2/21).

Let's call the x-intercept of the line h. Then the equation of the line is y = mx, and the area to the left of the line is:

(1/2)h(mx) = (1/2)mhx

We want this to be equal to (2/21), so we can solve for h:

(1/2)mhx = (2/21)

h = (4/21m)

The x-coordinate of the point of intersection of the line and the parabola is given by:

2x − 7[tex]x^2[/tex] = mx

Simplifying, we get:

[tex]7x^2 - (2 + m)x = 0[/tex]

Using the quadratic formula, we get:

[tex]x = [(2 + m) \pm \sqrt((2 + m)^2 - 4(7)(0))]/(2(7))[/tex]

x = [(2 + m) ± √(4 + 4m + [tex]m^2[/tex])]/14

x = [(2 + m) ± (2 + m)]/14

x = 1/7 or x = −(2/7)

Since we want the line to pass through the origin, we must choose x = 1/7, and we can solve for m:

[tex]2(1/7) - 7(1/7)^2 = m(1/7)[/tex]

m = 8/7

Therefore, the slope of the line that divides the region into two equal parts is 8/7.

Last week, the ratio of bananas sold to watermelons sold was 4 : 3.

This ratio means that for every 4 bananas sold, the number of watermelons sold was 3.

Since there were 48 bananas sold, we can find the number of watermelons sold by subtracting 12 from 48:

48 bananas - 12 = 36 watermelons

Now, we can determine the ratio of bananas sold to watermelons sold. The ratio would be:

Bananas : Watermelons = 48 : 36

To simplify this ratio, we can divide both numbers by their greatest common divisor (GCD), which in this case is 12:

48 ÷ 12 = 4
36 ÷ 12 = 3

So, the simplified ratio is:

4 : 3

This ratio means that for every 4 bananas sold, the number of watermelons sold was 3. In other words, out of every 7 fruits sold (4 bananas + 3 watermelons), 4 were bananas and 3 were watermelons.

The volume of the solid is 32/15 cubic units.

To find the volume of the solid, we need to integrate the area of each square cross section perpendicular to the x-axis over the interval [a, b], where a and b are the x-coordinates of the intersection points of f(x) and g(x):

First, we find the intersection points of the two functions:

x²+1 = 2x+1

x² - 2x = 0

x(x-2) = 0

x = 0 or x = 2

So, a = 0 and b = 2.

Next, we find the side length of each square cross section. Since the cross section is a square, the side length is equal to the difference between the y-coordinates of the functions f(x) and g(x) at each x:

Side length = f(x) - g(x) = (x²+1) - (2x+1) = x² - 2x

Finally, we integrate the area of each square cross section over the interval [0, 2] to get the volume of the solid:

V = ∫[0,2] (x² - 2x)² dx

V = ∫[0,2] (x⁴- 4x³ + 4x²) dx

V = [1/5 x⁵ - 1 x⁴ + 4/3 x³] [0,2]

V = (1/5 x⁵ - 1 x⁴ + 4/3 x³)|[0,2]

V = (1/5(2⁵) - 1(2⁴) + 4/3(2³)) - (1/5(0⁵) - 1(0⁴) + 4/3(0³))

V = (32/5 - 16/3)

Approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet.

To determine the number of people who can fit in a passenger car with a length of 70 feet and a width of 9 feet, we need to consider the available space inside the car and the amount of space required per person.

Assuming that the passenger car is a rectangular box shape, the volume of the car can be calculated as follows:

Volume of car = Length x Width x Height

Since we are only interested in the number of people who can fit in the car, we will assume a standard height of 6 feet for simplicity. Therefore, the volume of the car can be calculated as follows:

Volume of car = 70 feet x 9 feet x 6 feet

Volume of car = 3,780 cubic feet

Next, we need to determine the amount of space required per person. This can vary depending on the seating arrangement and the size of the individuals, but as a general rule, we can estimate that each person requires approximately 10 to 12 cubic feet of space in a seated position.

Assuming we use the lower end of that estimate and allocate 10 cubic feet of space per person, we can calculate the number of people who can fit in the car as follows:

Number of people = Volume of car / Space per person

Number of people = 3,780 cubic feet / 10 cubic feet per person

Number of people = 378 people

Therefore, if we assume a standard height of 6 feet and allocate 10 cubic feet of space per person, approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet. However, it is important to note that this is just an estimate and the actual number of people who can fit in the car will depend on factors such as the seating arrangement and the size of the individuals.

The property was not explicitly used in this example, but it is worth noting that adding 0 to any number leaves it unchanged (i.e., a + 0 = a).

The properties that were used to simplify the expression 4 + 3(9 + 2) into 37 are:

Distributive property: The expression was rewritten as 4 + (3 × 9) + (3 × 2) by distributing the 3 over the parentheses.

Associative property: The order of the terms (3 × 9) and (3 × 2) was rearranged without changing the result because of the associative property of multiplication.

Commutative property: The order of the terms 4, 27, and 6 was rearranged without changing the result because of the commutative property of addition.

Identity property: The property was not explicitly used in this example, but it is worth noting that adding 0 to any number leaves it unchanged (i.e., a + 0 = a).

The properties used to simplify the expression are Associative property of addition, Commutative property of addition, and Distributive property and Identity property of addition. Therefore, the correct option is A, C, E and F.

The properties used to simplify the expression are as follows.

1. Distributive property (E): 4 + 3(9 + 2) = 4 + (3 × 9) + (3 × 2)

This property is applied when a number is multiplied with the sum of two or more numbers. In this case, the number 3 is distributed over the numbers 9 and 2.

2. Identity property of addition (F): 4 + 27 + 6 = 4 + 6 + 27

This property states that adding zero to any number does not change its value. Although this property isn't explicitly shown in the given steps, it is implied by the fact that we can rearrange the terms in the addition without changing their value.

3. Commutative property of addition (C): 4 + 6 + 27 = 10 + 27

This property states that changing the order of numbers in an addition does not change the sum. Here, the numbers 4 and 6 were rearranged to make it easier to add them together.

4. Associative property of addition (A): (10 + 27) = 37

This property states that the grouping of numbers in an addition does not affect the sum. In this case, the parentheses are unnecessary since the numbers were already grouped correctly.

In summary, the properties used to simplify the expression are: A) Associative property of addition, C) Commutative property of addition, and E) Distributive property and F) identity property of addition.

The probability of the normal distribution with given mean and standard deviation representing average content in the selected bottles is smaller than 102.1 mL is equal to 0.9878.

Distribution of the sample means of a normal distribution ,

Mean μ = 101.5 mL

Standard deviationσ = 1.6 mL

sample size n = 36

For normal distribution,

Standard deviation of the sample means is,

σ/√n

= 1.6/√36

= 0.2667 mL

Probability that the average content in the selected bottles is smaller than 102.1 mL,

Standardize the sample mean using the formula,

z = (X- μ) / (σ/√n)

where X is the sample mean.

Substituting the values, we get,

⇒z = (102.1 - 101.5) / (0.2667)

⇒ z = 2.25

Using a standard normal distribution table ,

Probability of a z-score being less than 2.25 is approximately 0.9878.

Therefore, the probability that the average content in the selected bottles is smaller than 102.1 mL is approximately 0.9878.
