Let a submarine be at a constant depth of 5 km. It is headed in the direction of a lighthouse. If the distance between the submarine and the base of the lighthouse is decreasing at a rate of 24 km/h when the sub is 13 km away from the base, then what is the speed of the submarine

Answers

Answer:

24 km/h

Step-by-step explanation:

Given:

Constant speed of submarine = 24 km/h

Depth under sea = 5 km

Distance of submarine from lighthouse = 13 km

Find:

Speed of the submarine

Computation:

At steady speed, the distance between both the submarine and the lighthouse base decreases at a rate of 24 km/hr.

So, when it is 13 kilometres from its starting point, the speed remains constant at 24 kilometres per hour.

Suppose you have 3 bags. Two of them contain a single $10 bill, and the third contains a single $5 bill. Suppose you pick one of these bags uniformly at random. You then add a $5 bill to the bag, so it now contains two bills. The bag is shaken, and you randomly draw a bill from the bag without looking into the bag. Suppose it turns out to be a $5 bill. If a you draw the remaining bill from the bag, what is the probability that it, too, is a $5 bill

Answers

Answer:

1/2

Step-by-step explanation:

Number of bags = 3

number of bags with $10 bill initially = 2

number of bags with $5 bill initially = 1

assume :

event you pick a $5 bill at first draw = A

event you pick a $5 bill at second draw = B

hence : P ( A n B ) = 1/3 * 1 = 1/3

P( A ) = ( 1/3 * 1 ) + ( 1/3 * 1/2 + 1/3 * 1/2 )  = 2/3

therefore P( that the second drawn bill is $5 )

P( B | A ) = P(A n B ) / P ( A )

              = (1/3) / (2/3) = 1/2

The probability that it, too, is a $ 5 bill is 33.33%.

Since you have 3 bags, and two of them contain a single $ 10 bill, and the third contains a single $ 5 bill, supposing you pick one of these bags uniformly at random and you then add a $ 5 bill to the bag, so it now contains two bills, and the bag is shaken, and you randomly draw a bill from the bag without looking into the bag, supposing it turns out to be a $ 5 bill, if a you draw the remaining bill from the bag, to determine what is the probability that it, too, is a $ 5 bill, the following calculation must be performed:

3 bags = 2 with a 10 bill and 1 with a 5 bill 1/3 = 0.3333 0.3333 x 100 = 33.33

Therefore, the probability that it, too, is a $ 5 bill is 33.33%.

The length of a rectangle is four more than three times the width. If the perimeter of this rectangle is at least 70 square centimeters. Write an inequality that can be solved to find the width of the rectangle

Answers

Answer:

Step-by-step explanation:

Let L represent the length of the triangle.

Let W represent the width of the triangle.

The length of a rectangle is four more than three times the width. This means that

L = 3W + 4

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is

2(L + W) ≥ 70

L + W ≥ 70/2

L + W ≥ 35

Answer:

6w +8 ≥70

Step-by-step explanation:

Let w be the width

The length is then 3w+4 ("the length is 4 more than 3 times the width")

Since a rectangle has opposite sides equal, the perimeter would be 2(l+w) or 2(w+3w+4) which would be 6w +8.  If the perimeter is at least 70, that is, 70 or more, the inequality would be

  6w + 8 ≥ 70.  

The units, however, would not be SQUARE centimeters, just centimeters.  If the question were asking for area, the units would be square units, but since perimeter is a linear measurement,  the units would have to be linear.

3x + 6y = -42

Answers

Answer:

y = -1/2x -7

Step-by-step explanation:

3x + 6y = -42

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

Subtract 3x from each side

3x-3x+6y = -3x-42

6y = -3x-42

Divide each side by 6

6y/6 = -3x/6 - 42/6

y = -1/2x -7

I) Find the volume in terms of pie

ii) curved surface area in terms of pie

iii) capacity in litres (correct to nearest litre)

Answers

Answer:

i) pi×4500 cm³

ii) pi×600 cm²

iii) 14 liters

Step-by-step explanation:

in general : the diameter is 30 cm, the radius is half of that (15 cm)

i)

the volume of a cylinder is base area times height.

Vc = pi×r²×h = pi×15²×20 = pi×225×20 = pi×4500 cm³

ii)

similar to volume, the side "mantle" area of the cylinder is the circumference of the base area times height.

surface area of the cylinder mantle is

Scm = 2×pi×r×h = 2×pi×15×20 = pi×30×20 = pi×600 cm²

iii)

for this we need now to do the multiplication with pi and then convert the cm³ to liters.

1 liter = a cube of 10 cm side length = 10×10×10 = 1000 cm³

pi×4500 = 14137.17 cm³ = 14.13717 liters or rounded 14 liters

How To Demonstrate Successful Leadership In The Workplace By Dionne Mahaffey, Founder of The Life Purpose Coaching Institute As with all skills, some of us are more adept at leadership than others. However, if you find yourself lacking in this area, keep in mind that your current struggles may be taking you down the pathway to eventual success. You can leverage the key fundamentals of successful leadership in order to impact your team and become the leader you desire to be. Successful leaders are effective communicators. In fact, communication will most likely be the major building block of your success in leadership. What makes a communicator effective, exactly? I have found the following guidelines to be helpful: Always consider all angles before crafting your message. Think about the "who," "what" and "how" of the situation. Keep the following questions in mind: What is the issue at hand? How can it be solved? Who am I asking to take action? What are the possible obstacles? What tools will I need to provide to make the process easier? Make sure your message is understood. Anyone can deliver a message, but not everyone confirms that the message is understood. Dont hesitate to repeat yourself to make a point. Always ask your team members if they have any questions or comments. Wait five-to-10 seconds before moving on in order to give your team time to process the information and formulate responses. Manage and prevent conflicts with consideration and purpose. Handle conflict between employees immediately. Otherwise, you risk the creation of a toxic environment where employees fail to see you as a capable leader. Stay a step ahead and strive to prevent conflict by observing your employees and learning their emotional triggers. For example, consider your employees working styles: some are very methodical, plugging along to the end. Others procrastinate and then rush to accomplish everything at the last minute. A way to avoid conflict is to pair employees with similar working styles. Give specific and appropriate praise for individual and team efforts. When you specifically state what you appreciate, your praise should translate as being authentic, not as an empty gesture. For example, The candid testimonials you gathered gave us valuable insight on the product that we wouldnt have had otherwise. This conveys exactly what impressed you, and offers the bonus of reinforcing desired behavior.Title of Text: How to Demonstrate Successful Leadership in the WorkplaceAuthor: Dionne Mahaffey ---------------Subject: Occasion: Audience: Purpose: Speaker: Tone: Find f(-3) if f(x) = x2 .Type a numerical answer in the space provided.
