What is the cost of 0. 7 kg of apples, if 1 kg of apples cost 89. 50

Answers

Answer 1

In the proportion,  the cost of 0.7kg apple is Rs.62.65 .

What is proportion?

A percentage is created when two ratios are equal to one another. We write proportions to construct equivalent ratios and to resolve unclear values. a comparison of two integers and their proportions. According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.

Here cost of 1kg apples = 89.50

Then cost of 0.7 kg apple = x.

Now using proportion,

=> 1   = 89.50

   0.7=  x

=> x = [tex]\frac{89.50\times0.7}{1}[/tex]

=> x = 62.65.

Hence the cost of 0.7kg apple is Rs.62.65 .

Step-by-step explanation:

How might the graph be redrawn to emphasize the difference between the cost per doctor visit for each of the three plans? The scale on the y-axis could be changed to 0–100. The scale on the y-axis could be changed to 25–40. The interval of the y-axis could be changed to count by 5s. The interval of the y-axis could be changed to count by 20s.

Answers

To emphasize the difference between the cost per doctor visit for each of the three plans, you can change the scale on the y-axis to either 0–100 or 25–40 and adjust the interval of the y-axis to count by 5s.



To emphasize the difference, you can consider the following adjustments to the graph:

1. Change the scale on the y-axis to 0–100. This adjustment will give a wider range for the costs, making it easier to see the differences between the three plans.


2. Alternatively, change the scale on the y-axis to 25–40. This change will focus more on the specific cost range that the three plans fall into, magnifying the differences between them.


3. Change the interval of the y-axis to count by 5s. This alteration will increase the number of increments on the y-axis, giving a more detailed view of the cost differences between the plans.


4. On the other hand, changing the interval of the y-axis to count by 20s might not be the best option. It will decrease the increments on y-axis and make it harder to visualize the cost differences between the plans.

Six friends are selling crafts at a flea market. they each need to pay $7. 20 to pay

for the table rental. they each sell 3 items. if every item is the same price, and the

6 friends make a total profit of $25. 20, what was the sale price of each item?

Answers

To find the sale price of each item, we need to use some basic algebra. Let's call the sale price of each item "x".

First, we need to find the total cost of the table rental for all six friends. Since each friend needs to pay $7.20, the total cost of the table rental is 6 * $7.20 = $43.20.

Next, we need to find the total revenue from selling the items. Each friend sells 3 items, so the total number of items sold is 6 * 3 = 18. The total revenue is the number of items sold multiplied by the sale price, so the total revenue is 18x.

We know that the total profit is $25.20, which is the total revenue minus the total cost of the table rental. So we can set up the equation:

18x - $43.20 = $25.20

Simplifying this equation, we get:

18x = $68.40

Dividing both sides by 18, we get:

x = $3.80

Therefore, the sale price of each item is $3.80.

Based on the information provided, it is not clear what "they" refer to. However, it seems that there are two distinct events or phenomena being described here.

The first involves the albatross, which is known to be a migratory bird that visits certain regions at certain times of the year. It is unclear what exactly is being "kept" by the albatross, but it could be some sort of information or knowledge that is unique to this bird.

The second event or phenomenon is described as happening every night and involving various activities such as shooting, swimming, fighting, and singing.

It is unclear what this refers to exactly, but it could be some sort of nightly ritual or tradition that takes place in a particular community or region.

The statement that "separately, they would reveal many to you" suggests that each of these phenomena has its own unique insights or knowledge to offer.

However, the statement that "together, they will reveal only one to you" implies that there is some sort of deeper connection or meaning between these two events that is not immediately apparent.

The question of "whose one is it?" suggests that there is some sort of ownership or responsibility associated with this revelation.

It is unclear who this refers to, but it could be interpreted as asking who is responsible for uncovering the deeper meaning or connection between these two phenomena.

In summary, the information provided is somewhat cryptic and open to interpretation. However, it seems that there are two distinct events or phenomena being described, and that there is some sort of deeper connection or meaning between them that is not immediately apparent.

Answers

The probability of the next coat being sold as a medium navy coat is 11 / 95 when a store sells a coat in three sizes: small, medium, and large. The coat comes in red, navy, and tan.

We need to find the probability that the next coat sold as a medium navy coat. To find the probability we need to find the total number of coats and the number of medium navy coats,

Given data:

Medium navy coat = 22

Total Number of small coats = 18 + 24 +19 = 61

An airplane flies at 500 mph with a direction of 135* relative to the air. The plane experiences a wind that blows 60 mph with a direction of 60*

Answers

The plane's new velocity is 421.4 mph with a direction of 63.43 degrees relative to the air.

To solve this problem, we need to use vector addition. Let's first draw a diagram to represent the situation.

First, we need to break down the velocity of the plane and the velocity of the wind into their horizontal and vertical components.

The velocity of the plane can be broken down into a horizontal component of 500*cos(135) mph and a vertical component of 500*sin(135) mph.

The velocity of the wind can be broken down into a horizontal component of 60*cos(60) mph and a vertical component of 60*sin(60) mph.

Now, we can add these components together to get the resultant velocity.

The horizontal component of the resultant velocity is 500*cos(135) + 60*cos(60) = -189.28 mph. The negative sign indicates that the velocity is in the opposite direction of the plane's original direction.

The vertical component of the resultant velocity is 500*sin(135) + 60*sin(60) = 374.28 mph.

Using the Pythagorean theorem, we can find the magnitude of the resultant velocity:

|v| = sqrt((-189.28)^2 + (374.28)^2) = 421.4 mph.

Finally, we can find the direction of the resultant velocity using the inverse tangent function:

θ = tan^-1(374.28/-189.28) = -63.43 degrees.

So the plane's new velocity is 421.4 mph with a direction of 63.43 degrees relative to the air.

What is the Law of Sines?

The Law of Sines states that the ratio of a sine of an angle to the length of the side facing the angle is the same for the three sides of the triangle.

Jumal's approach

a. The measure of the angle B can be found as follows;

sin(40)/10 = sin(B)/15

B = 15 × arcsine(sin(40)/10) ≈ 74.6°

b. The measure of angle C can be found using the angle sum property of a triangle as follows;

∠C = 180 - (40 + 74.6) = 65.4°

c. The length of the side c is therefore;

sin(40)/10 = sin(65.4)/c

c = sin(65.4) × 10/sin(40) ≈ 14.1

The length of the side c is about 14.1 meters

The triangle can be obtained by using the specified and obtained dimensions as shown in the attached drawing

Jabari's Approach

a. The Law of Cosines indicates; a² = b² + c² - 2·b·c·cos(A)

Therefore;

100 = 225 + c² - 2 × 15 × c × cos(40)

10² = 15² + c² - 23·c

c² - 23·c + 125 = 0

In ΔLMN, m = 59 inches, n = 35 inches and ∠L=82°. Find ∠N, to the nearest degree

Answers

The answer is: ∠N ≈ 33°

To find ∠N in ΔLMN, we can use the Law of Cosines which states that c² = a² + b² - 2abcos(C), where c is the side opposite angle C.

In this case, side LM (m) is opposite angle ∠N, side LN (n) is opposite angle ∠L, and side MN (x) is opposite the unknown angle.

So, we can write:
m² = n² + x² - 2nxcos(82°)

Substituting the given values:
x² = 35² + 59² - 2(35)(59)cos(82°)

Solving for x, we get:
x ≈ 64.27

Now, using the Law of Sines which states that a/sin(A) = b/sin(B) = c/sin(C), we can find ∠N:

sin(∠N)/35 = sin(82°)/64.27

sin(∠N) ≈ 0.5392

∠N ≈ sin⁻¹(0.857) ≈ 32.6344°

Answers

The rounding method used, the estimated speed of the space shuttle after it has slowed down is 10,200 miles per hour.

To estimate the speed of the space shuttle after it has slowed down, we round each number to the nearest hundred. The speed before the decrease is rounded to 17,600 miles per hour, and the decrease in speed is rounded to 7,400 miles per hour.

Next, we subtract the rounded decrease in speed from the rounded speed before. So, 17,600 - 7,400 = 10,200 miles per hour. This result represents the estimated speed of the space shuttle after it has slowed down.

Rounding to the nearest hundred is a way to approximate the values and make calculations simpler. However, it is important to note that rounding introduces some degree of error, and the actual speed after the decrease may differ slightly from the estimated value.

The Mean-Value-Theorem is being used to explain why the driver received a speeding ticket even though they were traveling at exactly 60 mph at both radar-detectors. It suggests that there must have been a moment during the trip where the driver's speed was above the speed limit.

The Mean-Value Theorem is a theorem from calculus that states that for a continuous function on a closed interval, there exists at least one point in the interval where the instantaneous rate of change (the derivative) of the function is equal to the average rate of change of the function over the interval.

In this case, the police unit used the two radar detectors to determine the average-speed of the driver between the two points. The distance between the two detectors is 159 miles, and the time it took for the driver to travel that distance was 2 hours (from 2pm to 4pm), so the average speed of the driver was 159/2 = 79.5 mph.

However, the speed-limit on the highway is 65 mph, so the driver was exceeding the speed limit and received a speeding-ticket.

Answers

The equation that can be used to determine the number of people (x) who can go to the amusement park is:

207.50 = 5 + (33.75 × x).

To determine the number of people (x) who can go to the amusement park, we need to create an equation using the given information. We know that they have $207.50 to spend, parking costs $5, and each ticket costs $33.75 per person (including tax).

We can represent the total cost of the trip as the sum of the cost for parking and the cost of the tickets for x number of people. The equation would be:

Total Cost = Cost of Parking + (Cost of Tickets per Person × Number of People)

Since we know the total cost is $207.50, the cost of parking is $5, and the cost of tickets per person is $33.75, we can plug in these values:

This equation gives the light intensity, I (in lumens), in water at a depth of feet: d= -425log(I/12). I) What is the intensity of the light at a depth of 300 feet? Please show all work. Ii) At what water depth is the intensity 5 lumens? Please show all work. Iii) What is the light intensity at the surface of the water? Please show all work

Answers

i) The light intensity at a depth of 300 feet is approximately 0.131 lumens.

ii)The light intensity of 5 lumens is reached at a depth of approximately 106.6 feet.

iii)The light intensity at the surface of the water is 12 lumens.

The equation given is:

[tex]d= -425log(\frac{I}{12} )[/tex]

where d is the depth in feet, and l is the light intensity in lumens.

i)To find the intensity of light at a depth of 300 feet:

[tex]d= -425log(\frac{I}{12} )[/tex]

[tex]or, \frac{d}{-425}=log(\frac{I}{12})[/tex]

[tex]or, 10^{\frac{d}{-425}}=\frac{I}{12}[/tex]

[tex]or, 12 X 10^{\frac{d}{-425}}=I[/tex]

Given, d= 300 feet. Hence,

[tex]or, 12 X 10^{\frac{300}{-425}}=I[/tex]

or, I = 0.131 lumens (approx.)

ii) We have been given the equation :

[tex]d= -425log(\frac{I}{12} )[/tex]

when I =5 lumens

[tex]d= -425log(\frac{5}{12} )[/tex]

or, d = 106.6 feet (approx.)

iii) For finding the light intensity at the surface of the water d=0

[tex]d= -425log(\frac{I}{12} )[/tex]

Putting d = 0 we get

[tex]0= -425log(\frac{I}{12} )[/tex]

[tex]or, log(\frac{I}{12})=0[/tex]

[tex]or, \frac{I}{12} = 10^0 = 1[/tex]

or, I = 12 lumens

Therefore the light intensity at the surface of the water is 12 lumens.

An instructor graded 200 papers and found 80 errors. If a paper is picked at


random, find the probability that it will have exactly 4 errors

Answers

The probability of a paper having exactly 4 errors can be calculated using the binomial probability formula, which is:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

What is the probability of selecting a paper at random from 200 papers and instructor found 80 errors and the probability that a paper has exactly 4 errors?

In binomial probability formula P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

n is the number of trials (in this case, the number of papers graded)

k is the number of successes (in this case, the number of papers with exactly 4 errors)

p is the probability of success (in this case, the probability that a paper has an error, which can be calculated by dividing the total number of errors by the total number of papers graded)

Calculate the probability of a paper having an error

p = 80/200 = 0.4

Calculate the probability of a paper having exactly 4 errors

P(X = 4) = (200 choose 4) * 0.4^4 * (1-0.4)^(200-4) ≈ 0.153

Therefore, the probability of picking a paper at random and finding exactly 4 errors is approximately 0.153 or 15.3%.

Step-by-step explanation:

Peyton built a birdhouse in the shape of a pyramid with a square base.



The dimensions of the base were 16 in. By 16 in.


The slant height of the pyramid is 10 in.


What is the surface area of the birdhouse?


A. 262 in. 2


B. 576 in. 2


C. 640 in. 2


D. 1,280 in. 2

Answers

To find the surface area C of the birdhouse, we need to find the area of each face and add them together.

First, let's find the area of the square base:

Area of base = side^2 = 16^2 = 256 in^2

Next, let's find the area of each triangular face:

Area of each triangular face = 1/2 * base * height

Since the base is 16 in and the slant height is 10 in, the height can be found using the Pythagorean theorem:

height^2 = slant height^2 - base^2/4

height^2 = 10^2 - 16^2/4

height^2 = 100 - 64

height^2 = 36

height = 6

So the area of each triangular face is:

1/2 * 16 * 6 = 48 in^2

There are four triangular faces, so the total area of the triangular faces is:

4 * 48 = 192 in^2

Finally, we add the area of the base and the area of the triangular faces to find the total surface area:

256 + 192 = 448 in^2

Therefore, the surface area of the birdhouse is 448 square inches, which is closest to option A: 262 in^2.
