Answer:

\(y = \frac{1094-3x}{47}\)

General Formulas and Concepts:

Step-by-step explanation:

Step 1: Define equation

3x + 47y = 1094

Step 2: Solve for y

Answer:

1) 1388.1

2) x = 176.8

z = 176.8

y = 241.1

3) x = 205.1

z = 205.1

y = 279.7

Step-by-step explanation:

\(sin(\theta) = \frac{opp}{hyp} \\\\cos(\theta) = \frac{adj}{hyp} \\\\tan(\theta) = \frac{opp}{adj}\)

1)

x = 1046

∠A = 53

tan A = h/x

h = x * tanA

h = 1046*tan(53)

=1388.1

2)

Since AD is the horizontal tine, it is parallel to BC

⇒ ∠BAD = 90

⇒ ∠BAC + ∠CAD = 90

⇒ ∠BAC + 45 = 90

⇒ ∠BAC = 90 - 45

⇒ ∠BAC = 45

In ΔABC,

∠BAC + ∠ABC + ∠ACB  = 180

45 + 90 + ∠ACB  = 180

∠ACB  = 45

Since ∠ACB  = ∠BAC, the sides opposite to these angle are equal

⇒ x = z

By pythagorean theorem

x² + z² = 250²

⇒ x² + x² = 250²

⇒ 2x² = 250²

⇒ x² = 250²/2

⇒ x = √[250²/2]

⇒ x = 250/√(2)

⇒ x = 176.8

⇒ z = 176.8

In Δ AED,

AD = z

∠EAD = 20

⇒ tan(EAD) = DE/AD

⇒ DE = AD * tan(EAD)

⇒ DE = z * tan(20)

y = CD + DE

⇒ y = x + z *tan(20)

⇒ y = x + x *tan(20)

⇒ y = x (1 + tan(20))

⇒ y = 250 (1 + tan(20))/√(2)

⇒ y = 241.1

3) Since AD is the horizontal tine, it is parallel to BC

⇒ ∠BAD = 90

⇒ ∠BAC + ∠CAD = 90

⇒ ∠BAC + 45 = 90

⇒ ∠BAC = 90 - 45

⇒ ∠BAC = 45

In ΔABC,

∠BAC + ∠ABC + ∠ACB  = 180

45 + 90 + ∠ACB  = 180

∠ACB  = 45

Since ∠ACB  = ∠BAC, the sides opposite to these angle are equal

⇒ x = z

By pythagorean theorem

x² + z² = 290²

⇒ x² + x² = 290²

⇒ 2x² = 290²

⇒ x² = 290²/2

⇒ x = √[290²/2]

⇒ x = 290/√(2)

⇒ x = 205.1

⇒ z = 205.1

In Δ AED,

AD = z

∠EAD = 20

⇒ tan(EAD) = DE/AD

⇒ DE = AD * tan(EAD)

⇒ DE = z * tan(20)

y = CD + DE

⇒ y = x + z *tan(20)

⇒ y = x + x *tan(20)

⇒ y = x (1 + tan(20))

⇒ y = 290 (1 + tan(20))/√(2)

⇒ y = 279.7

Adding a derivational suffix to a word often changes the part of speech is true.

What is derivational suffix ?

A derivational suffix is a type of affix that is added to the end of a base word to create a new word with a different meaning, often a different part of speech.

For example, adding the derivational suffix "-ness" to the base word "kind" creates the new word "kindness," which is a noun that refers to the quality or state of being kind. Similarly, adding the derivational suffix "-able" to the base word "value" creates the new word "valuable," which is an adjective that describes something that is worth a lot.

Derivational suffixes can change the meaning and function of a word, and they are often used to create new words in English. Some common derivational suffixes include "-er," "-able," "-ness," "-ful," "-ish," and "-ize."

Answer: 1/4

Step-by-step explanation:

Let the volume of mixture (6%fat) in cup is 100cc

x cc be the volume of cream (18% fat) in the mixture.

∴

(100−x) cc be the volume of milk (2% fat) in the mixture.

x * 0.18+(100−x) * 0.02=100

⋅0.06 or 0.18x − 0.02x = 6−2 or 0.16x

= 4 or x=25 cc = 25%

Note that

\(x^2 - y^2 = (x - y) (x + y)\)

Step-by-step explanation:

first you want to flip 2/5 to 5/2 and change the division sign to multiplication so it would look like 1/9 x 5/2

then multiply 1 and 5 then 9 and 2 so the top and bottom to get 5/18

side note: but if it were 1/9 x 3/7 you would change the 3 to a 1 and the 9 to a 3 because they multiply so ask yourself how many times does three go into 9 so it would be 1/3 x 1/7= 1/21

The following statements correctly describe how the graph of the geometric sequence: 640, 160, 40, 10, ... should appear:

The given sequence is 640, 160, 40, 10, ... which is a geometric sequence.

Here, the first term is 640 and the common ratio is ¼

The terms of a geometric sequence can be written as an = a₁(r)⁽ⁿ⁻¹⁾

Here, a₁ = 640, and r = ¼.

Hence, the nth term of the given sequence is given by the formula:

an = 640(1/4)⁽ⁿ⁻¹⁾

The graph of the given sequence will appear as shown below:

The given sequence is a decreasing sequence, which means the terms of the sequence keep decreasing as the value of n increases.

Therefore, the graph will show exponential decay.

The domain of the sequence will be the set of natural numbers, which is {1, 2, 3, ...}, since we cannot find any term before the first term.

Therefore, the first term is the initial term and we can count the other terms of the sequence in natural numbers.

Hence, the domain will be the set of natural numbers.

Answer:

Step-by-step explanation:

The appropriate test for comparing the means of two measurement methods is a paired t-test. Therefore, the answer is (a) paired t-test.

A paired t-test is used to compare the means of two related groups or samples. In this case, the two measurement methods are applied to the same sample of carp, and the results of the two methods are paired or matched by carp. The paired t-test calculates the mean and standard deviation of the differences between the two methods for each carp, and then tests whether the mean difference is significantly different from zero.

The paired t-test is an appropriate test in this scenario because it accounts for the variability within the sample and reduces the potential impact of confounding factors, such as differences in the size or age of the fish. Additionally, since the sample size is relatively small (18 carp), a t-test is more appropriate than a z-test, which assumes larger sample sizes and a known population standard deviation.

The 95% confidence interval for the proportion of smokers is (0.72, 0.88).

The proportion of smokers in a sample of 100 men has been calculated to be 80. We will utilize this information to create a 95% confidence interval of the proportion of smokers between two limits.

Here's how to do it:Solution:We have selected a sample of 100 men to estimate the proportion of smokers. In that sample, 80 of them were smokers.

Therefore, we may assume that the proportion of smokers in the sample is 0.8. Using this sample proportion, we can calculate the 95% confidence interval of the proportion of smokers.

Confidence interval of proportion of smokers is given by;\(CI = \left( {{\hat p} - {z_{\frac{\alpha }{2}}}\sqrt {\frac{{{\hat p}\left( {1 - {\hat p}} \right)}}{n}}} \right),\left( {{\hat p} + {z_{\frac{\alpha }{2}}}\sqrt {\frac{{{\hat p}\left( {1 - {\hat p}} \right)}}{n}}} \right)\)where,\(n = 100\)\(\hat p = \frac{x}{n} = \frac{80}{100} = 0.8\)\(\alpha = 1 - 0.95 = 0.05\)\(\frac{\alpha }{2} = \frac{0.05}{2} = 0.025\)

Since we know the values of \(\hat p\), \(\alpha\), \(\frac{\alpha}{2}\) and \(n\), we may calculate the confidence interval as follows:\(CI = \left( {0.8 - {z_{0.025}}\sqrt {\frac{{0.8\left( {1 - 0.8} \right)}}{{100}}}} \right),\left( {0.8 + {z_{0.025}}\sqrt {\frac{{0.8\left( {1 - 0.8} \right)}}{{100}}}} \right)\)\(CI = \left( {0.72,0.88} \right)\)

Hence, the 95% confidence interval for the proportion of smokers is (0.72, 0.88).

Therefore, the answer is option OA (0.72 0.88).

Measure the time it takes for the dog to run a certain distance.

Step-by-step explanation:

The percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second is  28.87%.

Given that the carrying capacity is directly proportional to the area, we can write:

C1 ∝ A1 = πr₁²

Since the carrying capacity is directly proportional to the area, we have:

C2 ∝ A2 = πr₂²

To find the percentage increase in diameter, we need to find the ratio of the increased area to the initial area and then express it as a percentage. Let's calculate this ratio:

(A2 - A1) / A1 = (πr₂² - πr₁²) / (πr₁²) = (r₂² - r₁²) / r₁²

We can also express the ratio of the increased carrying capacity to the initial carrying capacity:

(C2 - C1) / C1 = (60 - 36) / 36 = 24 / 36 = 2 / 3

Since the area and the carrying capacity are directly proportional, the ratios should be equal:

(r₂² - r₁²) / r₁² = 2 / 3

Now, let's substitute r = D/2 in the equation:

((D₂/2)² - (D₁/2)²) / (D₁/2)² = 2 / 3

(D₂² - D₁²) / D₁² = 2 / 3

Cross-multiplying:

3(D₂² - D₁²) = 2D₁²

3D₂² - 3D₁² = 2D₁²

3D₂² = 5D₁²

Dividing by D₁²:

3(D₂² / D₁²) = 5

(D₂² / D₁²) = 5 / 3

Taking the square root of both sides:

D₂ / D₁ = √(5/3)

To find the percentage increase in diameter, we subtract 1 from the ratio and express it as a percentage:

Percentage increase = (D₂ / D₁ - 1) × 100

Percentage increase = (√(5/3) - 1) × 100

Percentage increase = 28.87%

The transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

The rule that describes the transformation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

To understand this, let's apply the transformation rule to each vertex of the original parallelogram ABCD:

Point A (2, 5) becomes A' (-5, 2).

Point B (5, 4) becomes B' (-4, 5).

Point C (5, 2) becomes C' (-2, 5).

Point D (2, 3) becomes D' (-3, 2).

By applying the transformation rule, we observe that the x-coordinate of each point becomes the negative of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.

This transformation is a 90-degree counterclockwise rotation about the origin (0, 0) on the coordinate plane. The image parallelogram A'B'C'D' is obtained by rotating the original parallelogram ABCD by 90 degrees counterclockwise.

Visually, this transformation can be seen as the original parallelogram being rotated around the origin, where the x-axis becomes the y-axis, and the y-axis becomes the negative x-axis.

Therefore, the transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

Answer:

The profit function P(x) is defined as the difference between the revenue function R(x) and the cost function C(x): P(x) = R(x) - C(x). Substituting the given functions for R(x) and C(x), we get:

P(x) = (-31.72x^2 + 2030x) - (-126.96x + 26391) = -31.72x^2 + 2156.96x - 26391

To find the maximum profit, we need to find the vertex of this quadratic function. The x-coordinate of the vertex is given by the formula x = -b/(2a), where a = -31.72 and b = 2156.96. Substituting these values into the formula, we get:

x = -2156.96/(2 * (-31.72)) ≈ 34

Substituting this value of x into the profit function, we find that the maximum profit is:

P(34) = -31.72(34)^2 + 2156.96(34) - 26391 ≈ $4,665

The selling price of the dog food is given by the revenue function divided by x: R(x)/x = (-31.72x^2 + 2030x)/x = -31.72x + 2030. Substituting x = 34 into this equation, we find that the selling price of the dog food should be set to:

-31.72(34) + 2030 ≈ $92

So, the maximum profit of $4,665 can be made when the selling price of the dog food is set to $92 per bag.
