a) The length of Captain Jack's ship is: 95.17 m

b) The height above the deck of the Ship is: 34.64 m

a) In triangle ABC, we can say that:

tan 30 = AB/h

where:

h is height above deck of ship

We are give AB = 20 m and as such:

h = 20/tan 30

h = 34.64 m

b) To find the the length of Captain Jack's ship:

BC = h * tan 70

BC = 34.64 * tan 70

BC = 95.17 m

Answer:

392600 divided by 1208 = 325

Step-by-step explanation:

Answer:

325 apples

Step-by-step explanation:

1208 boxes have 392600 apples

1 box will have x apples

1208/392600 = 1/x

Cross multiplying,

1208x = 392600

Dividing by 1208 on both sides,

x = 392600/1208 = 325 apples

Answer: x = 27.5

Step-by-step explanation:

      We cannot solve for y in the equation, since we are only given an x value.

     Given:

7x + 10 = 3x + 120

    Subtract 3x from both sides of the equation:

4x + 10 = 120

    Subtract 10 from both sides of the equation:

4x = 110

      Divide both sides of the equation by 4:

x = 27.5

Answer:

C. The note on the package only told customers to call in the event that they had a concern, which could bias the results negatively.

Explanation:

Since customers were only told to call if they had concerns, all of the calls were about concerns or problems that they were having - meaning all of the calls were negative. However, they were never informed to call if they were happy or content with the product, meaning they were never informed of the people who had positive comments, only negative.

Answer:

y = ± √ 7/2

Step-by-step explanation:

2*y^2-8-(6-2*y^2)=0

(2 • (y2)) - 8) - (6 - 2y2) = 0

(2y2 - 8) - (6 - 2y2) = 0

Pull out like factors :

4y2 - 14 = 2 • (2y2 - 7)

4.2 Factoring: 2y2 - 7

difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

2 • (2y2 - 7) = 0

5.1 Solve : 2 = 0

5.2 Solve : 2y2-7 = 0

Add 7 to both sides of the equation :

2y2 = 7

Divide both sides of the equation by 2:

y2 = 7/2 = 3.500

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

y = ± √ 7/2

Answer:

Karl should make 4 Flower picture frames and 1 Planets picture frame to maximize his total profit while satisfying the constraints of cost, number of picture frames, and time.

Step-by-step explanation:

Let's use x to represent the number of Flower picture frames Karl makes and y to represent the number of Planets picture frames he makes.

The profit made from selling a Flower picture frame is $10 - $4 = $6, and the profit made from selling a Planets picture frame is $13 - $5 = $8.

The cost of making x Flower picture frames and y Planets picture frames is 4x + 5y, and Karl can only spend $150 on costs. Therefore, we have:

4x + 5y ≤ 150

Similarly, the number of picture frames Karl can make is limited to 30, so we have:

x + y ≤ 30

The time Karl spends making x Flower picture frames and y Planets picture frames is 0.5x + 1.5y, and he has 25 hours to spend. Therefore, we have:

0.5x + 1.5y ≤ 25

To maximize profit, we need to maximize the total profit function:

P = 6x + 8y

We can solve this problem using linear programming. One way to do this is to graph the feasible region defined by the constraints and identify the corner points of the region. Then we can evaluate the total profit function at these corner points to find the maximum total profit.

Alternatively, we can use substitution or elimination to find the values of x and y that maximize the total profit function subject to the constraints. Since the constraints are all linear, we can use substitution or elimination to find their intersections and then test the resulting solutions to see which ones satisfy all of the constraints.

Using substitution, we can solve the inequality x + y ≤ 30 for y to get:

y ≤ 30 - x

Then we can substitute this expression for y in the other two inequalities to get:

4x + 5(30 - x) ≤ 150

0.5x + 1.5(30 - x) ≤ 25

Simplifying and solving for x, we get:

-x ≤ -6

-x ≤ 5

The second inequality is more restrictive, so we use it to solve for x:

-x ≤ 5

x ≥ -5

Since x has to be a non-negative integer (we cannot make negative picture frames), the possible values for x are x = 0, 1, 2, 3, 4, or 5. We can substitute each of these values into the inequality x + y ≤ 30 to get the corresponding range of values for y:

y ≤ 30 - x

y ≤ 30

y ≤ 29

y ≤ 28

y ≤ 27

y ≤ 26

y ≤ 25

Using the third constraint, 0.5x + 1.5y ≤ 25, we can substitute each of the possible values for x and y to see which combinations satisfy this constraint:

x = 0, y = 0: 0 + 0 ≤ 25, satisfied

x = 1, y = 0: 0.5 + 0 ≤ 25, satisfied

x = 2, y = 0: 1 + 0 ≤ 25, satisfied

x = 3, y = 0: 1.5 + 0 ≤ 25, satisfied

x = 4, y = 0: 2 + 0 ≤ 25, satisfied

x = 5, y = 0: 2.5 + 0 ≤ 25, satisfied

x = 0, y = 1: 0 + 1.5 ≤ 25, satisfied

x = 0, y = 2: 0 + 3 ≤ 25, satisfied

x = 0, y = 3: 0 + 4.5 ≤ 25, satisfied

x = 0, y = 4: 0 + 6 ≤ 25, satisfied

x = 0, y = 5: 0 + 7.5 ≤ 25, satisfied

x = 1, y = 1: 0.5 + 1.5 ≤ 25, satisfied

x = 1, y = 2: 0.5 + 3 ≤ 25, satisfied

x = 1, y = 3: 0.5 + 4.5 ≤ 25, satisfied

x = 1, y = 4: 0.5 + 6 ≤ 25, satisfied

x = 2, y = 1: 1 + 1.5 ≤ 25, satisfied

x = 2, y = 2: 1 + 3 ≤ 25, satisfied

x = 2, y = 3: 1 + 4.5 ≤ 25, satisfied

x = 3, y = 1: 1.5 + 1.5 ≤ 25, satisfied

x = 3, y = 2: 1.5 + 3 ≤ 25, satisfied

x = 4, y = 1: 2 + 1.5 ≤ 25, satisfied

Therefore, the combinations of Flower and Planets picture frames that satisfy all of the constraints are: (0,0), (1,0), (2,0), (3,0), (4,0), (5,0), (0,1), (0,2), (0,3), (0,4), (0,5), (1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,1), (3,2), and (4,1).

We can evaluate the total profit function P = 6x + 8y at each of these combinations to find the maximum profit:

(0,0): P = 0

(1,0): P = 6

(2,0): P = 12

(3,0): P = 18

(4,0): P = 24

(5,0): P = 30

(0,1): P = 8

(0,2): P = 16

(0,3): P = 24

(0,4): P = 32

(0,5): P = 40

(1,1): P = 14

(1,2): P = 22

(1,3): P = 30

(1,4): P = 38

(2,1): P = 20

(2,2): P = 28

(2,3): P = 36

(3,1): P = 26

(3,2): P = 34

(4,1): P = 32

Therefore, the maximum total profit is $32, which can be achieved by making 4 Flower picture frames and 1 Planets picture frame.

Therefore, Karl should make 4 Flower picture frames and 1 Planets picture frame to maximize his total profit while satisfying the constraints of cost, number of picture frames, and time.

The regular expression is ^(a(aa)*b)$.

To create a regular expression for the language L = {w = {a,b}* | w has an odd number of 'a's and ends with 'b'}, we can use the following expression:

^(b|(a(aa)*b))$

Breaking it down:

^ indicates the start of the string.

(b|(a(aa)*b)) matches either 'b' or a sequence of 'a's followed by an odd number of 'a's and 'b'.

(aa)* matches zero or more pairs of 'a's.

$ indicates the end of the string.

This regular expression ensures that the string starts with 'b' or a sequence of 'a's, followed by an odd number of 'a's, and ends with 'b'. Any additional characters or sequences in between are not allowed.

Please note that regular expressions can have different notations and conventions depending on the context or programming language you're using. The expression provided here follows a general pattern that should work in most cases.

The variable x has a range of values of 7 < x < 25

The given parameter in the triangle represented by the figure

From the triangle, we can see that:

The red line bisects the side length BD to BC and CD

However, it does not bisect the angle at point C

By the representation of the line, we can see that

Angle BCA is less than angle DCA

Mathematically, this is represented as

BCA < DCA

So, we have

5x - 35 < 90

This gives

5x < 125

Divide by 5

x < 25

Also, the angle must be greater than 0

So, we have

5x - 35 > 0

This gives

5x > 35

Divide by 5

x > 7

Combine the inequality x > 7 and the inequality x < 25

The result is 7 < x < 25

Hence, the range of x is 7 < x < 25

Finding the area of a parallelogram is very similar to finding the area to that of a rectangle.

The equation for area A is \(A=bh\) where b is the base length and h is the height.

We are given a base length of 15 inches, and the height of the parallelogram is 7 inches (not 9 inches).

The length of the frame the width is 22

What is the perimeter of a frame whose length is 22 inches and whose breadth is 14 inches?

The distance around an object is called the perimeter.

For instance, the yard of your home is fenced in. The perimeter is the length of the fence. Your fence is 200 feet long if the yard is 50 feet by 50 feet.

The answer to the above-mentioned difficulty is provided here.

We will search for the length since the frame's breadth is 14 inches and its perimeter is 72 inches. 2L + 2W is the perimeter formula.

Therefore, let's swap the values.

P = 2L + 2w

72 = 2L + 2(14) (14)

72 = 2L + 28
