Derek has a cylindrical water bottle with a diameter of 4 centimeters and a height of 15 centimeters. If he filled the water 3/4 full of water, how much water is in the water bottle?

Answers

Answer 1

Answer:

141 3/8

Step-by-step explanation:

First find the volume by multiplying pi, the radius squared, and the height. Pi is 3.14. The radius is half the diameter, so it would be 2. 2^2 is 4. The height is 15. 3.14*4*15=188.5 Then multiply 3/4 and 188.5 to get your answer. 141.375 or 141 3/8.

Suppose Ms. Smith sells her 2018 Honda Fit next year. The original cost of the vehicle was $10,000. During the time she has owned the car she has taken $3,000 dollars of deprecation on it. Ms. Williams sells the car for $9,000. What is result of the transaction

Answers

Answer:

An ordinary gain of $2,000

Step-by-step explanation:

Cost of the vehicle(C)=$10,000

Depreciation(D)=$3,000

Selling price(S)=$9,000

Worth of the vehicle= Cost price - depreciation

=$10,000-3,000

=$7,000

Net worth= selling price - worth of the vehicle

=$9,000-$7,000

=$2,000

Answer:

transaction would be a profit of $ 2,000.

Step-by-step explanation:

Given:-

- The original cost of the vehicle, C = $ 10,000

- The depreciation of the vehicle until the time of selling, d = $3,000

- The price at which the vehicle is sold, S = $ 9,000

Find:-

What is result of the transaction

Solution:-

- Whenever an asset is bought the value of the asset depreciates. There are several tools and methods to estimate the amount of depreciation.

- After n years of possession of car / since manufactured the asset undergoes depreciation until its sold or salvaged.

- Here Ms Smith possessed her car for a certain amount of time t years.

- The accumulated depreciation at the time she sold her car was " d ".

- So at the point of selling her car the actual worth or value of her car was ( C* ):

                              C* = C - d

                              C* = $10,000 - $3,000

                              C* = $7,000

- Now her car's value is ( C* ). If she sells her for " S " higher than current asset worth then she will profit from it otherwise she would sustain a loss in her selling transaction. So the net asset worth she would have after selling her car would be:

                             Net Worth = S - C*

                             Net Worth = $9,000 - $ 7,000

                             Net Worth = $ 2,000

Answer: The net worth is a positive value that means she sold her car for higher value than its worth; hence, the transaction would be a profit of $ 2,000.

The number of mosquitoes in a field after a major rainfall is modeled by the function M defined by M(t)=−t3+12t2+144t , where t is the number of days after the rainfall ended and 0≤t≤18 . Using correct units, interpret the meaning of M′(15)=−171 in the context of the problem.

Answers

Answer: The rate at which mosquitoes are appearing in a field 15 days after the rainfall ended is -171. I believe this to be correct.

M'(15) = -171 means that after 15 days, the number of mosquitoes is decreasing at a rate of 171 mosquitoes per day.

Interpreting the Function

The function M(t) represents the number of mosquitoes in a field after t days have passed since a major rainfall. The derivative of this function, M'(t), represents the rate of change of the number of mosquitoes.

M'(15) = -171 means that after 15 days, the number of mosquitoes is decreasing at a rate of 171 mosquitoes per day. In other words, the population of mosquitoes is declining by 171 mosquitoes each day.

the width of the rectangular garden is eleven feet less than the length. find the dimensions. if the area is 80 square feet

Answers

Answer:

the dimensions are;

Width = 14.5 ft

Length = 25.5 ft

Step-by-step explanation:

We are told that width is 11 feet less than length. Let Width be W and Length be L.

Thus;

W = L - 11

Area of rectangle is given by;

Area; A = 2W + 2L

Putting L - 11 for width, we have;

Area = 2(L - 11) + 2(L)

A = 2L - 22 + 2L

A = 4L - 22

Length = L

Width = W

Area = A

A =4L-22

We are told that Area is 80 square feet. Thus;

80 = 4L -22

Add 22 to both sides to give;

102 = 4L

Divide both sides by 4 to give;

102/4 = 4L/4

L = 25.5

Recall that; W = L - 11

Thus;

W = 25.5 - 11 = 14.5

So the dimensions are;

Width = 14.5 ft

Length = 25.5 ft

Step-by-step explanation:

Considering 'x' no. of ounces of one solution and 'y' no. of ounces of other solution.

Lets form the equations according to the given data.

-> she wishes to obtain 85 ounces by combining both solutions

x+y= 85

x = 85- y -->eq(1)

-> by combining a 72% acid solution with a 25% acid solution  

0.72x + 0.25 y = 0.4 x 85 --> eq(2)

Substituting value of eq(1) in eq(2)

0.72(85-y) + 0.25 y = 34

61.2 - 0.72y + 0.25y = 34

-0.47y= 34-61.2

y= 27.2/0.47

y= 57.87 ounces

Plugging in eq(1)

eq(1)=> x = 85- 57.87

x= 27.13 ounces

Therefore, Misty should use 27.13 ounces of one solution and 57.87 ounce of other solution

When do you not use the completing the square method

Answers

Answer:

You can use it in different ways

Step-by-step explanation:

sometimes it may be in correct as it is not a 100 percent way to get and answer

You do not use the completing the square method when the quadratic coefficient is not a perfect square, when the middle coefficient is odd, or when dealing with complex numbers. The quadratic formula is often more efficient under these circumstances.

The completing the square method is typically not used in certain circumstances in solving quadratic equations. For example, it is not the best approach when the quadratic coefficient (the 'a' term when the quadratic is in the form ax^2+bx+c=0) is not a perfect square and cannot be easily made into one. Additionally, this method is often avoided if the middle coefficient (the 'b' term) is odd, making it cumbersome to deal with fractional or decimal numbers when completing the square.

Instead, it might be more efficient to use the quadratic formula, which can handle any type of quadratic equation. The quadratic formula, x equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a', provides a direct solution without the need for making any initial transformations to the equation. This formula is also preferred when the equation has coefficients that do not lend themselves to simple arithmetic or when the equation is not easily factorable.

In contrast, the completing the square method is best when dealing with integrals in calculus or when you need the equation in vertex form for analyzing the properties of a parabola. In such scenarios, completing the square provides additional insight into the problem at hand.

The number of words per page in a certain book is normally distributed with a mean of 340 words and a standard deviation of 20 words.

Approximately what percent of pages in the book are less than 360 words in length?

Answers

Answer:

Step-by-step explanation:

Since the number of words per page in the book is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = number of words per page.

µ = mean

σ = standard deviation

From the information given,

µ = 340 words

σ = 20 words

The probability that the number of pages in the book are less than 360 words in length is expressed as

P(x < 360)

For x = 360,

z = (360 - 340)/20 = 1

Looking at the normal distribution table, the probability corresponding to the z score is 0.84

The percent of pages in the book that are less than 360 words in length is

0.84 × 100 = 84%

sodas combined. You must report the number of hot dogs sold and the
number of sodas sold. How many hot dogs were sold and how many sodas
were sold:
Let x = the number of hot dogs sold
Let y = the number of sodas sold
write your answer as an ordered pair (x,y)​

Answers

x= hot dogs

y= soda

Total sold

1 x + 1 y = 87 .............1

2 x 0.50 y = 78.50 .............2

Eliminate y

multiply (1)by -0.50

Multiply (2) by 1.00

-0.50 x -0.50 y = -43.50

2 x + 0.50 y = 78.50

Add the two equations

1 x = 35.00

/ 1

x = 35.00

plug value of x in (1)

1 x + 1 y = 87

35 + y = 87

y = 87 -35

y = 52

y = 52.00

x= 35 hot dogs

y= 52 soda

Final answer:

The number of hot dogs and sodas sold can be determined using a system of linear equations. By solving these equations, it was found that 35 hot dogs and 52 sodas were sold, represented as an ordered pair (35, 52).

Explanation:

Let's solve the problem of determining the number of hot dogs (x) and sodas (y) sold at a concession stand. Given that each hot dog costs $1.50 and each soda costs $0.50, and the total revenue is $78.50 for 87 items sold, we can set up two equations:

1.50x + 0.50y = 78.50 (The revenue equation)x + y = 87 (The total items equation)

Now, let's use these equations to find x and y by substitution or elimination. If we multiply the second equation by 0.50, we get:

0.50x + 0.50y = 43.50

Subtract this new equation from the first one to eliminate y:

1.50x + 0.50y = 78.50-(0.50x + 0.50y = 43.50)x = 35 (Number of hot dogs sold)

Now, plug x back into the second original equation:

35 + y = 87

So, y = 52 (Number of sodas sold).

The answer as an ordered pair is: (35, 52), where 35 represents the number of hot dogs sold, and 52 represents the number of sodas sold.

Tickets for a play were $2 for each child and $4 for each adult. At one showing of the play, one adult brought 4 children and the remaining adults brought 2 children each. The total ticket sales from the children and adults are $60. How many CHILDREN attended the play

Answers

Answer:

16 children attended the play

Step-by-step explanation:

Since one adult brought four children. The cost of their tickets should be:

($4×1) + ($2×1)

= 4+8

= $12

Since the remaining adults brought 2 children each, it means that each of the remaining adults will pay the cost of three tickets (1 for themselves and 2 for their children) which is:

($4×1) + ($2×2) = $4 + $4 = $8.

Since total cost of tickets for adults and children = $60, we will subtract $12 from $60 in order to know the cost of the tickets for the remaining adults and their children.

$60 - $12 = $48

Each of the remaining adults paid $8 as ticket cost for themselves and their kids. If the adults that brought only 2 kids paid a combined $48, then the number of adults that brought 2 kids each

= $48/$8

= 6 adults.

If each of these 6 adults brought 2 kids each, then the number of children that they brought = 2 × 6 = 12

We now add this to the four children of the first adult

12 + 4 = 16

Therefore the number of children that attended the play = 16

Final answer:

The problem is solved by setting up and solving equations, determining that 16 children attended the play.

Explanation:

The subject of this problem is setting up and solving equations. The given information can be translated into equations. Four children and one adult make up one group. For this group, the total cost is $4 (for the adult) + $2 * 4 (for the children) = $12. For the remaining adults and children, we know each adult brought 2 children and the cost would be $4 (for the adult) + $2 * 2 (for the children) = $8 per group. We know the total cost was $60. So, subtract the $12 from the first group, which leaves $48. As we know each of the remaining groups cost $8, we divide $48 by $8 to find that there were 6 more groups. Each of these groups consists of 1 adult and 2 children, so there were 6 * 2 = 12 children in these groups. Added to the original 4 children, that makes 16 children in total.

Goal: Determine the most affordable way to package 12 cans of soda.
Details:
● Height of each can: 5 inches
● Radius of each can: 2 inches
All cans must be packaged so that they are standing upright like such----->

Answers

Answer:

Option 3

Step-by-step explanation:

If the radius of the can is 2 inches, then the diameter must be 4 since the diameter is 2 times the radius. So we want to make it as small as possible. I think the best option is option 3 because it is tight and it is stacked nicely. The package wrapping will not have much to go around. I hope this helps! please mark me brainliest! Thanks!
