What is the angle between the hands when it is quarter past 330 Answers
7.5 degrees. The hour hand would have moved past 3 in order for it to be 3:15.
Time for me to go
Depends on the clock. For starters let's assume it's an analogue display. If the hour hand only moves on the hour as opposed to at a set rate around the clock, then it would be 0. If it moves at a set rate, then the angle would be 7.5 degrees. (Full circle is 360 degrees, 12 hours on the face so it moves 30 degrees every hour or 7.5 degrees every quarter hour).
Near enough to 0 to not worry about, I am sure there is a website with a more accurate answer if you really want to know. This is interesting as the question is/was "If the time is quarter past 3, what is the angle measurement on the clock?" What are we measuring? If everything was plumb and level then it might 90 degrees. I know the table my digital clock sits on is not level but I have never measured the wonkyness of the table.
I really don't care
Presumably the interviewer is asking for the angle of the hands on the clock taken from the midpoint therefore the correct answer is 180 degrees. If the time was three o'clock then the answer would be 90 degrees. Some of the answers here make me question what is being taught in schools these days, I don't mean to sound patronising but I remember my angles from my Primary School days which were in the 1970s!!
Gillian, Please put on this nice pointy hat and sit in the corner.... Quarter past 3 = 180 degrees? Are you sure about that?
90 degrees acutely and 270 degrees obtusely
No scrub that the answer I gave was for 3 o'clock. 3.15 would be 7.5 degrees or inversely 352.5 degrees.
It's on the right hand side about a quarter of the way round the clock.
The minutes hand stood at 90 deg the 15 minutes lapse will move the hour hand to 90 + (15/60 * 30 deg) = 97.5 deg difference = 7.5 deg
Somewhere between minus and plus infinity. Modulus 360 degrees, of course.
7.5 degrees. The minute hand will be 90 degrees past the vertical, the hour hand (which moves 30 degrees per hour) has moved 3.25 * 30 degrees since noon so is at 97.5 degrees past vertical. Difference = 7.5 degrees.
1. Discreet-placed arrows clock. 0 degrees 2. Ordinary clock 360/12/(1/4) = 7.5 degrees
I'm Sorry. 360/12*(1/4) = 7.5
Well each hour mark on the clock is 30 degrees from 12pm. The hour hand moves 30 degrees per 1 hour, 15 degrees per half hour, 7.5 degrees per 15minutes. The minute hand is at 90 degrees from 12pm and the hour hand is at 97.5 degrees from 12pm. The difference is then, as many others have said, 7.5 degrees.
How many calories are in a grocery store?9 Answers
Perhaps breaking up the grocery store into it's main categories and estimating the caloric density of each type of food may be the way to go? E.g. Frozen foods (high density), meats (medium), junk food and soda (high), veggies (low), non-food items (none), dairy (high), packaged foods (medium). Then estimate how space is typically allocated on these categories (10%, 20%, etc.). Then estimate how many such items can fit in, say a 10 ft area that has 3 positions (top, middle, bottom). Scale up the estimate as needed. Assign values to caloric density and at the least, you have solved the problem. Probably not the most elegant solution but it's what comes to mind immediately.
I would not consider these questions as hard or random at all..It would answer to How do you calculate how many calories are in a grocery store? like "I don't count at all..I am pretty thin. Actually I am trying to gain some weight so I just consume food like a trash bin.." what's wrong with that? Why would I even count that at all? I dont really care.. Some people might count and they could ansver to this question differently.
There are no calories in a grocery store. There are calories in food which is inside the grocery store, but none in the grocery store itself!
The answer is none. Calories are found in food, not stores.
A calorie is defined as: the energy needed to raise the temperature of 1 gram of water through 1 °C. The average grocery store is 4000m^2. Assuming average energy density of 200 calories/m^2 (Calories in a medium pizza) there should be 800000 calories in a grocery store.
Edible calories or calories in general? Because if the answer is the second we should use Einstein's formula: the weight of the grocery stores itself (in kg) plus everything in it * 1000 * c^2. The result then is divided by 4.16 (Calories/Joule) and woilà we have the number of calories in the store. If instead is the first answer, well, just approximate through the methods someone else explained.
My local grocery store (supermarket) has 10 checkouts operating during busy times. Assume on average it takes 2 minutes to service each customer. That's 30 customers per hours x 10 checkouts = 300 customers per hour. Assume the store is busy 4 hours per day, that's 1,200 customers and that accounts for 80% of the store's turnover so 1,500 customers per day. Assume on average each customer is buying enough food for 2 people, that's 3,000 people. People on average consume 2,000 calories per day but not all of it comes from the grocery store, let's say 75% does that's 1,500 calories. Putting it all together 3,000 people * 1,500 calories = 4,500,000 calories per day ... but wait there's more. If the store turns over stock on average every 5 days that means there's 5 days of calories on the shelves, that's 22,500,000 calories. Lots of assumptions but the answer seems reasonable
Other than the nobody likes a smart aleck answer of stores don't have them, food does, I would suggest the research needed to determine that would take longer than an interview would allow. It would take research to determine the size of an average store the amount of stock held at given times of the year and its type, and the average levels of calories in the food stocks. On a side not it has been widely reported that labelling of such products is not very informative, so might I suggest it be represented pictorially biased towards the mostly female psyches. Perhaps a collection of images and statements ranging from a picture of an attractive successful business women say Ashley Madison material? To a picture of Chuck Blazer running from the feds on a mobility scooter saying this is what your husband is going to be like in ten years?
Depends on the size of the grocery store and what products it stocks.
How many times does the Earth rotate around its own axis while it makes one revolution around the sun?5 Answers
Little more than 365
The earth completes 1 rotation on its own axis approximately every 24hrs The earth completes 1 rotation around the sun approximately every 365 days So the number of rotations on it's own axis after completing 1 rotation around the sun is: 24 rotations per day x 365 days = 8,760 rotations.
one time more than the number of days in a year
365. Second response is funny: - The earth completes 1 rotation on its own axis approximately every 24hrs; + I add that one day as 24hrs; - 24 rotations per day.... Well I didn't know we had a 576hrs days :)
While it makes 365 complete rotations around the sun, to answer the question being asked, the answer would have to be that the earth is constantly rotating around its own axis.

* Imagine you were creating a search engine for events, how would you go about it?3 Answers
1) First the User base for a event search engine
1) First the User base for a event search engine a) People who want to post/create events on the website. Event organizers, career websites, concert halls, restaurants etc would like to create events etc. b) People who would want to browse this website for searching events. We would land an user on the event search web page, listing the most common events of her location. The browser can select location and then look for an event by a category (music, networking, food, art etc.) and/or event type (conference etc). The user can also initiate a keyword based search. The engine should be capable of a keyword initiated search, and apply any filter (category, event type etc.) on top of that. A search should bring back a list of results, having key information about the events, name, location, ticket information etc. The location when hovered over should show a map. As an integrated service user should be able to buy tickets for the event, read and write reviews for the event. People should be also able to create events on this website. They would be provided with a simple form, giving the name, type, location, time and description of the event. They can also sell tickets through this website. Revenue Model: Basic Search/Event creation on this website must be free. However if user clicks on a particular event , the event creator can be charged. In addition, if the user buys ticket through this website, a part of the ticket price should go to the search engine website. The search engine website should measure the following in order to gauge her business. 1) Number of people visiting/searching on the website. 2) Number of people positing on the website, and the event category and type they generally post for. How many of them are re-posting. 3) How many clicks do the users make per day. 4) What kind of events are most searched for in given geographical locations/time of year etc. 5) Ticket sales through the website. 6) How friendly the website it to outside search engines. For example, how many times it gets hit from a google.com, 7) How popular is the website for ticket sales, are there returning customers for ticket sales, and how helpful are the reviews.
Nice Answer !!
