The height of a rectangle is multiplied by 4. Which of the following describes the effect of this change on the area?The area is multiplied by 16.The area is multiplied by 8.The area is multiplied by 4.The area is multiplied by 2.

Answers

Answer 1

The correct option is: The area is multiplied by 4.

The height of a rectangle is multiplied by 4. This change in the area is that the area is multiplied by 4. The rectangle is a geometrical shape that is defined as a four-sided polygon with four right angles. Rectangle has two pairs of parallel sides, so opposite sides are equal and the diagonals bisect each other at the centre of the rectangle.

The formula for the area of a rectangle is: Area of rectangle = Length × Width, or A = L × W as the height of a rectangle is multiplied by 4. Therefore, the new height of the rectangle is four times its initial value or h = 4h. The area of the rectangle can now be calculated using the above formula, which is:

New Area of rectangle = length x 4h = 4 × (length x h) = 4 x Area of rectangle

The effect of increasing the height of the rectangle by 4 times is that the area of the rectangle is multiplied by 4.

Use Lagrange multipliers to find the points on the given cone that are closest to the following point.
z^2 = x^2 + y^2; (14, 8, 0)
x,y,z=(smaller z-value)
x,y,z=(larger z-value)

Answers

x,y,z=(smaller z-value)=(-56/3, -32/3, 16/3)

x,y,z=(larger z-value)=(56/3, 32/3, -16/3)

These are the points on the cone that are closest to the point (14, 8, 0).

What is a point?

In a two-dimensional space, a point is defined by two coordinates, typically denoted by (x, y), where x represents the horizontal position, and y represents the vertical position. In a three-dimensional space, a point is defined by three coordinates, typically denoted by (x, y, z), where x, y, and z represent the horizontal, vertical, and depth positions, respectively.

According to question:

We want to minimize the distance between the point (14, 8, 0) and the surface of the cone defined by the equation z² = x² + y², subject to the constraint that we stay on the surface of the cone.

Let f(x,y,z) = (x-14)² + (y-8)² + z² be the function we want to minimize subject to the constraint g(x,y,z) = z² - x² - y² = 0.

The Lagrange multiplier method involves finding the critical points of the function L(x,y,z,λ) = f(x,y,z) - λg(x,y,z), where λ is the Lagrange multiplier.

So we have:

L(x,y,z,λ) = (x-14)² + (y-8)² + z² - λ(z² - x² - y²)

Taking the partial derivatives with respect to x, y, z, and λ, and setting them equal to zero, we get the following system of equations:

2(x-14) + 2λx = 0

2(y-8) + 2λy = 0

2z - 2λz = 0

z² - x² - y² = 0

The third equation simplifies to z(1-λ) = 0, which gives us two possibilities:

Case 1: z = 0

In this case, the fourth equation becomes -x² - y² = 0, which implies that x = y = 0. But this point does not lie on the surface of the cone, so it is not a valid critical point.

Case 2: λ = 1

In this case, the first two equations become x-14 = -xλ and y-8 = -yλ, which imply that x = -7λ and y = -4λ. Substituting into the fourth equation gives:

z² = x² + y² = 65λ²

To minimize the distance between the point (14, 8, 0) and the surface of the cone, we want to find the value of λ that minimizes the function f(x,y,z) subject to the constraint g(x,y,z) = 0. Substituting x = -7λ, y = -4λ, and z = √(65λ²) into f(x,y,z), we get:

f(λ) = (7λ-14)² + (4λ-8)² + 65λ²

To minimize this function, we take its derivative with respect to λ and set it equal to zero:

f'(λ) = 30λ - 80 = 0

Solving for λ, we get λ = 8/3. Substituting this back into x = -7λ, y = -4λ, and z = √(65λ²), we get:

x,y,z=(smaller z-value)=(-56/3, -32/3, 16/3)

x,y,z=(larger z-value)=(56/3, 32/3, -16/3)

These are the points on the cone that are closest to the point (14, 8, 0).

The length of a rectangular room is 9 feet longer than twice the width. If the​ room's perimeter is 150 ​feet, what are the​ room's dimensions?

Answers

Answer:

Length = 53 feet

Width = 22 feet

Step-by-step explanation:

Perimeter = 2(length + width)

Then:

a = 2w + 9            Ec. 1

150 = 2(a + w)       Ec. 2

a = length

w = width

From Eq. 1:

a - 9 = 2w            Eq. 3

From Eq. 2:

150 = 2*a + 2*w

150 = 2a + 2w

150 - 2a = 2w        Eq. 4

Equalizing Eq. 3 and Eq. 4

a - 9 = 150 - 2a

a + 2a = 150 + 9

3a = 159

a = 159/3

a = 53

From Eq. 1:

a = 2w + 9

53 = 2w + 9

53 - 9 = 2w

44 = 2w

44/2 = w

w = 22

Check:

From Eq. 2

150 = 2(a+w)

150 = 2(53+22)

150 = 2*75

2/5 - 4 1/8 / (-2 1/4)

Answers

Step-by-step explanation:

let's first transform these terms into real fractions :

2/5 = 2/5

4 1/8 = (4×8 + 1)/8 = 33/8

2 1/4 = (2×4 + 1)/4 = 9/4

first we need to handle the division (remember the priorities of arithmetic operations) :

-33/8 / -9/4 = (-33×4) / (-9×8) = 33 / (9×2) = 33/18

then we have to calculate

2/5 + 33/18

to do that we have to bring both fractions to the same denominator (must be divisible by 18 and by 5, so in this case it is 5×18 = 90) :

2/5 = 2/5 × 18/18 = 36/90

33/18 = 33/18 × 5/5 = 165/90

so,

36/90 + 165/90 = 201/90 = 67/30 = 2 7/30

Two angles of an irregular polygon are 100⁰
each and each of the remaining angles is 1300.
Find the number of sides of the polygon.

Answers

there is no polygon that satisfies the given conditions.

Why it is and what is a Polygon?

Let the number of sides of the polygon be n.

We know that the sum of angles of an n-sided polygon is (n-2) × 180 degrees.

In this polygon, two angles are 100 degrees each, and the remaining (n-2) angles are 130 degrees each.

So, we can set up an equation:

2 × 100 + (n-2) × 130 = (n-2) × 180

Simplifying this equation, we get:

200 + 130n - 260 = 180n - 360

Solving for n, we get:

50n = 100

n = 2

However, a polygon with only 2 sides is not possible.

Therefore, there is no polygon that satisfies the given conditions.

A polygon is a 2-dimensional geometric figure that is formed by connecting a finite number of line segments to create a closed shape. These line segments are called sides of the polygon. The sides of a polygon only intersect at their endpoints, and the endpoints of each side are called vertices. A polygon with three sides is called a triangle, a polygon with four sides is called a quadrilateral, and a polygon with more than four sides is generally referred to by its number of sides (e.g. a pentagon has five sides, a hexagon has six sides, etc.).

A toy maker needs to make $17,235 per month to meet his cost. Each toy sells for $45. How many toys does he need to sell in order to break even

Answers

Answer:

Step-by-step explanation:

i assume the figure he needs to "make" is the turnover and not the marginal profit - no indication of the cost of the toys he sells is given so it is impossible to work out the marginal profit of the each toy sold. (Though how the toymaker worked out the turnover required without knowing the cost of the toy is beyond me - though that didn't stop British Leyland pricing their best selling Mini in the 1970s.)

In this case divide the income required by the price of each toy, but as the income must be at least the required amount, any fractional part of a toy must be rounded *UP* to the next whole number.

17,235 ÷ 45 = 383 (so no rounding is needed).

He needs to sell 383 toys (made at zero marginal cost).

Answers

Answer:

To solve the system of equations:

n + d = 21 ---(1)

0.05n + 0.10d = 1.70 ---(2)

We can use the substitution method by solving for one variable in terms of the other from equation (1) and substituting it into equation (2).

Solving equation (1) for n:

n = 21 - d

Substituting this expression for n into equation (2):

0.05(21 - d) + 0.10d = 1.70

Distributing the 0.05:

1.05 - 0.05d + 0.10d = 1.70

Combining like terms:

0.05d = 0.65

Dividing both sides by 0.05:

d = 13

Substituting this value of d into equation (1):

n + 13 = 21

Solving for n:

n = 8

Therefore, the solution to the system of equations is n = 8 and d = 13.

What is exponential growth?

A data pattern known as exponential growth exhibits faster expansion over time. Compounding generates exponential profits in finance. Exponential growth is possible in savings accounts with a compounding interest rate. Compound returns in finance lead to exponential development. One of the most potent forces in finance is the power of compounding. With the help of this idea, investors may generate sizable sums with little start-up money. Compound interest savings accounts are typical instances of exponential development.

Given that, population of a town increases by 3% each year.

The population after 5 years is calculated by:

Population in 5 years = Initial population x (1 + rate) raised to time.

That is,

Population in 5 years = 25,000 x (1 + 0.03)⁵

Population in 5 years = 25,000 x 1.159274

Sugar Shack gourmet candy shop’s signature candy mixture contains sour drops, chocolate chews, and tangy twists in the ratio 2:3:4, respectively. How many more pounds of tangy twists than sour drops are in a 45-pound batch of this signature candy mixture?

Answers

Since Sour Drops, Chocolate Chews and Tangy Twists are in the ratio 2:3:4, respectively, it follows that Sour Drops account for 2/9 and Tangy Twists account for 4/9 of the candy mixture. So, Sour Drops make up (2/9)(45) = 2 × 5 = 10 pounds, while Tangy Twists make up (4/9)(45) = 4 × 5 = 20 pounds of the 45-pound candy mixture. Therefore, there are 20 – 10 = 10 pounds more Tangy Twists than Sour Drops. Alternatively, the given ratio means that Tangy Twists account for 4/9 – 2/9 = 2/9 more of the candy mixture than Sour Drops do. So, in a 45-pound batch of the candy mixture, there would be (2/9)(45) = 2 × 5 = 10 pounds more Tangy Twists than Sour Drops.

Nyelle purchases some Sour Drops, Chocolate Chews and Tangy Twists to combine into her personal batch of the Sugar Shack’s signature candy mixture using the same proportions as the previous problem. If the prices per pound for the candies are $6.00 for Sour Drops, $3.50 for Chocolate Chews and $4.25 for Tangy Twists, what is the total cost (not including tax) to purchase the exact amounts of all three candies required to make 4.5 pounds of this signature candy mixture?

Again, since Sour Drops, Chocolate Chews and Tangy Twists are in the ratio 2:3:4, respectively, it follows that Sour Drops, Chocolate Chews and Tangy Twists account for 2/9, 3/9 = 1/3 and 4/9 of the candy mixture, respectively. So, to make 4.5 pounds of this candy mixture, Nyelle needs (2/9)(4.5) = 2 × 0.5 = 1 pound of Sour Drops, (1/3)(4.5) = 1.5 pounds of Chocolate Chews and (4/9)(4.5) = 4 × 0.5 = 2 pounds of Tangy Twists. At the given prices per pound, we calculate Nyelle’s total cost to be 1(6.00) + 1.5(3.50) + 2(4.25) = 6 + 5.25 + 8.50 = $19.75.

Rae purchases 4.5 pounds of the signature candy mixture when it goes on sale at the Sugar Shack for $4.00 per pound. What is the absolute difference between Nyelle’s and Rae’s total costs (not including tax) to get 4.5 pounds of the signature candy mixture?

At a sale price of $4.00 per pound, 4.5 pounds of the candy mixture would cost Rae 4.5(4.00) = $18.00. From the previous problem, we know that Nyelle’s total cost was $19.75. Therefore, the absolute difference between Nyelle’s and Rae’s total costs is 19.75 – 18.00 = $1.75.

Water freezes at 0º Celsius and 32º Fahrenheit. It boils at 100ºC and 212ºF. a) Find a linear function C that expresses temperature in the Celsius scale in terms of degrees Fahrenheit. b) Use this function to convert 110ºF into Celsius.

Answers

a) To find a linear function that expresses temperature in Celsius in terms of degrees Fahrenheit, we need to use the formula for converting Fahrenheit to Celsius:

C = (F - 32) * 5/9

This formula shows that to convert Fahrenheit to Celsius, we first subtract 32 from the Fahrenheit temperature, then multiply by 5/9.

If we rearrange this formula, we can solve for C in terms of F:

C = (F - 32) * 5/9

C = 5/9 * F - 5/9 * 32

C = 5/9 * F - 160/9

So the linear function C that expresses temperature in Celsius in terms of degrees Fahrenheit is:

C = 5/9 * F - 160/9

b) To use this function to convert 110ºF to Celsius, we simply substitute F = 110 into the equation:

C = 5/9 * F - 160/9

C = 5/9 * 110 - 160/9

C = 61.11ºC

Therefore, 110ºF is equivalent to 61.11ºC.

Answer:

a) To find a linear function that expresses temperature in Celsius in terms of degrees Fahrenheit, we can use the formula:

C = (F - 32) * 5/9

where C is the temperature in Celsius and F is the temperature in Fahrenheit.

b) To convert 110ºF to Celsius, we can plug in F = 110 into the formula above and simplify:

C = (110 - 32) * 5/9

C = 78 * 5/9

C = 43.33ºC

Therefore, 110ºF is equivalent to 43.33ºC in Celsius.

The area of the given shape is 109.25 ft² .

What is Area?

Area is a measurement of the amount of space inside a two-dimensional figure or shape. It is the size of the surface of the shape, and it is measured in square units, such as square meters, square centimeters, or square inches.The area of a shape can be found by multiplying the length and width of a rectangle or the base and height of a triangle, or by using specific formulas for other shapes such as circles, trapezoids, or parallelograms

Given : height of triangle = diameter of semicircle = 10 ft

            radius of semicircle = 5 ft

           base of triangle = 14 ft

we know that, The area of given shape :

= area of given triangle + area of semi circle

=  1/2 × base × height  +   πr²/2

= 1/2 × 14 × 10 + (3.14 × 5²)/2

= 70 + 39.25

= 109.25 ft²

Jo read 35 pages of a 250 page book. How much of a book has she read

Answers

Jo has read 14% of the book if she has read 35 pages of a 250 pages book.

If Jo has read 35 pages out of a 250-page book, we can calculate what percentage of the book she has read by dividing the number of pages she has read by the total number of pages and multiplying by 100:

Percentage of book read = (35 / 250) x 100%

Percentage of book read = 0.14 x 100%

Percentage of book read = 14%

Therefore, Jo has read 14% of the book. Percentage is a way of expressing a number as a fraction of 100. It is often used to describe the relationship between a part and a whole, where the part represents a portion of the whole. Percentages are commonly used in various fields, including mathematics, finance, and statistics, to measure changes or represent data in a more accessible format.

a committee of 7 members is to be chosen from 6 artists, 4 singers and 5 writers. in how many ways can this be done if in the committee there must be at least one member from each group and at least 3 artists ?

Answers

There are 1124 ways to choose a committee of 7 members with at least one member from each group and at least 3 artists.

Here, we have to solve this problem, we can use the concept of combinations, which involves counting the ways to choose a specific number of items from a larger set without regard to the order of selection.

Given the conditions that at least one member must be chosen from each group (artists, singers, writers) and there must be at least 3 artists, we can break down the problem into cases.

Case 1: Choosing 1 artist, 1 singer, and 5 members from the remaining groups (writers).

Case 2: Choosing 2 artists, 1 singer, and 4 members from the remaining groups (writers).

Case 3: Choosing 3 artists, 1 singer, and 3 members from the remaining groups (writers).

For each case, we will calculate the number of ways to choose members and then sum up the results from all three cases to get the total number of ways.

Let's calculate the number of ways for each case:

Case 1:

Number of ways to choose 1 artist: 6C1 (6 ways)

Number of ways to choose 1 singer: 4C1 (4 ways)

Number of ways to choose 5 writers: 5C5 (1 way)

Total ways for case 1: 6C1 * 4C1 * 5C5 = 6 * 4 * 1 = 24

Case 2:

Number of ways to choose 2 artists: 6C2 (15 ways)

Number of ways to choose 1 singer: 4C1 (4 ways)

Number of ways to choose 4 writers: 5C4 (5 ways)

Total ways for case 2: 6C2 * 4C1 * 5C4 = 15 * 4 * 5 = 300

Case 3:

Number of ways to choose 3 artists: 6C3 (20 ways)

Number of ways to choose 1 singer: 4C1 (4 ways)

Number of ways to choose 3 writers: 5C3 (10 ways)

Total ways for case 3: 6C3 * 4C1 * 5C3 = 20 * 4 * 10 = 800

Now, add up the total ways from all three cases:

Total ways = 24 + 300 + 800 = 1124

So, there are 1124 ways to choose a committee of 7 members with at least one member from each group and at least 3 artists.

How many more students slept 4 – 7 hours than 12 – 15 hours?

Answers

There were 8-1 = 7 more students who slept for 4-7 hours than for 12-15 hours.

In a survey conducted by Mr. Hamilton, he asked his class about the total number of hours they slept the previous night. The histogram provided in the question shows the distribution of their responses. To find out how many more students slept for 4-7 hours than 12-15 hours, we need to count the number of bars in the 4-7 hours range and subtract it from the number of bars in the 12-15 hours range. By counting the bars in the histogram, we can see that there are 9 bars in the 4-7 hours range and 4 bars in the 12-15 hours range. Therefore, there were 5 more students who slept for 4-7 hours than 12-15 hours.

6. The second section includes this sentence: "He cautioned

(the parents, though, that the pendulum could swing

back. " This sentence employs which literary device?

Answers

The literary device used in the sentence is a metaphor.

The metaphor in this statement is a literary tactic. It is an example of a figure of speech that contrasts one object with another of a specific type in order to emphasise or make a description more understandable. The figurative statement the pendulum could swing back alludes to prospect of a scenario reversing or shifting.

The analogy makes a comparison between a scenario that can go either way and a pendulum, which swings back and forth. In this instance, the author is warning the parents that the current circumstance, whatever it may be, could alter and go the other way. The metaphor places a strong emphasis on the notion of change and the potential for unpredictability in the future.

pre-warnt g The g the l e the l the l a n no. If you entered x=0 into your equation, you would receive this result. Your original amount is the part of your equation that is NOT increased to the x power.

We must take the amount of pepper Deion used from the total amount he had in order to determine how much pepper he still has.

Initial amount of pepper = 4.22 grams

Amount of pepper used = 1.92 grams

Pepper remaining = Initial amount - Amount used

Pepper remaining = 4.22 grams - 1.92 grams

Pepper remaining = 2.30 grams

Therefore, Deion has 2.30 grams of pepper left.

How to add decimal fractions?

The equation we are given is sixteen hundredths plus six-tenths

Now, when we talk about the decimal hundredths. Hundredths after decimal points shows 1/100th part of a whole. It represents the place value of the digit that occurs two places after the decimal.

Thus:

sixteen hundredths = 16/100

Similarly, six-tenths = 6/10

Thus:

The sum is:

16/100 + 6/10
