The greatest depth of the Southern Ocean is 7.24

Step-by-step explanation:

So, if you add all the greatest depths up, you get 33.23

(33.23 + x)/5 = 8.094

Multiply each side by 5

33.23 + x = 40.47

Subtract 33.23 from each side

x = 7.24

You can check this by adding all the numbers up and dividing them by 5

40.47/5 = 8.094

Step-by-step explanation:

One

2/3 = 0.6666

4/5 = 0.8

5/6 = 0.8333

On a number line, the last 2 would be close to 1 and 4/5 would be closer to the center than 5/6.

2/3 is over half so it would be closest to the 1/2 point and the furthest left of the the points.

I have a quiz that I did not study for and it s my fault because I had the time but it s so hard, but that is no excuse. So if someone is willing to help me please do! there are 16 questions. So I understand if you don t want to help and that s okay. Here are the questions 1. Neurons . a. connect to one another b. are part of muscle tissue c. receive messages with their axons d. send messages from their axons 2.What does the plant do with the extra glucose produced from photosynthesis? Select all that apply. a. It is stored in the plant as fructose.

I ve got an energy and work problem. the premise of the problem is: a crate with a mass of m is on a ramp that is inclined at an angle of 30° from the horizontal. a force with a magnitude of f directed parallel to the ramp is used to pull the crate with a constant speed up the ramp a distance of d. there are a set of subquestions and i ve answered them as best as i can, but i don t think i m right. could someone give me the answers and me understand why i m wrong? 1. what is the work done on the crate by the applied force f? --i said cos30 * f

Step-by-step answer

Refer to the diagram shown below.

μ = the coefficient of dynamic friction between the crate and the ramp.

1. The applied force of F acts over a distance, d.
The work done is F*d.

2. The component of the weight of the crate acting down the ramp is
mg sin(30) = 0.5mg.
The work done by this force is 0.5mgd.

3. The normal force is N = mgcos(30) = 0.866mg.
This force is perpendicular to the ramp, therefore the work done is zero.

4. The frictional force is μN = μmgcos(30) = 0.866μmg.
The work done by the frictional force is 0.866μmgd.

5. The total force acting on the crate up the ramp is
F - mgsin(30) - μmgcos(30) = F - mg(0.5 - 0.866μ)

6. The work done on the crate by the total force is
d*(F - 0.5mg - 0.866μmg)

I can definetely see why this is confusing. I myself am getting extremely confused as well.
I believe the assignment has two options to pick from. Part A, is a topic for the assignment, and so is part B.
Once you choose between the two, follow the instructions in the part you've chosen, and you should be fine.
Hope this helps!:)

Read the speech. “Ich bin ein Berliner” by John F. Kennedy Schöneberger Rathaus, West Berlin, July 1963 Two thousand years ago, two thousand years ago, the proudest boast was civis Romanus sum. Today, in the world of freedom, the proudest boast is Ich bin ein Berliner. (I appreciate my interpreter translating my German.) There are many people in the world who really don t understand, or say they don t, what is the great issue between the free world and the Communist world. Let them come to Berlin. There are some who say that communism is the wave

Yet Another Graduation Requirement? Daniel Thrash Current Requirements for Graduation: Today’s high school students are required to do and achieve more than ever before in order to receive their high school diploma. Originally students simply had to earn an established number of credits over four years in order to graduate. Then different state legislatures began to require students to pass either “End-of-Course” exams or state exams in addition to earning a certain number of credits. At first the required “end-of-course” or state exams needed
