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.

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.

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

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.

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

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).

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.

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)

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.

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.
