Sorry i'm really bad at math, can someone help me with this one?
Kendra bought her mother a new television for her birthday. If the television cost $239.99 and sales tax was 6%, what was the total amount Kendra spent on the gift? Round your answer to the nearest cent, if necessary. here's the multiple choice, lol A. $254.39 B. $245.99 C. $14.40 D. $383.98
I'm really really really bad at math! help me plz!?
1) A house valued at $7000 was insured at 80% of its value. What was the premium, if the rate was $6 per $1000? (I got $33.60. Is that right?) 2) In distributing milk at a summer camp, it is found that a quart of milk will fill either 3 large glass tumblers or 5 small glass tumblers. How many small glass tumblers can be filled with one large glass tumbler? (I got 1 and 2/3. Is that right?) 3) A can of food feeds 3 kittens or 2 dogs. If I have 8 cans of food and I feed 12 kittens, how many dogs can I feed? ( I got 8. Is that right?) 4) ( I can't show you the diagram, so I'll try my best to explain.) There is an upside down triangle inscribed in Circle O. The angle on the left is angle A. The angle on the right is angle B. O is the vertex. Arc AB is 112 degrees. OA = 4. How many degrees are in angle ABO? (I really don't understand circles...) Please help me!
IM REALLY BAD AT MATH! SO PLEASE HELP!?!?!?!?
OK, the formula for circumference is pi x d. Since you know the diameter, just multiply by pi. Usually, you just substitute 3.14 for pi. 3.14x18.8=59.032 So your circuference is 59.032m. To divide fractions, you multiply by the reciprocal, which is the fraction flipped upside down. 5 is equal to 5/1. So its reciprocal is 1/5. Now multiply 15/16 by 1/5 15x1=15 16x5=80 So your answer is 15/80, which can be simplified to 3/16. A good math website is math.com, you can just search for a topic you don't understand. This website is also great for math questions- Just ask people to explain topics if you don't understand. Good luck!
PLEASE HELP! MATH! IM REALLY BAD AT IT!?
Zemy- I'm considering quitting participation in Yahoo Answers! too: They've royally screwed it up to the point that you can't even see the question you're trying to answer. #2: C #7: B 11: A 12: The area of a triangle is 1/2 Width x Height. 120x^6y^3 = 1/2 * 40x^4y * length. L = 6 x^2y^2. Ans. C 13: (You seriously are unwilling to multiply 23,000 * 1.03 * 10? I'm outta here!)
Another math statistics question...please help...I'm really bad at math?
To answer these questions, it helps to know what each term means. The formulas for each would help too. A). The mean age is just the average age. The units of the mean are just the same as the units of what you're averaging. What's the average price of a car? Whatever that answer is, it's in dollars. So in this case, the mean age is in the same units that the observed ages were recorded in: years. B). Standard deviation... so tricky to understand if you look into it enough. A Standard Deviation, like any measurement is can be thought of as a measure of "uniqueness" from the average. If we're talking about tests, and you got a score close to average, it's a common score. If you fail it completely it's pretty unique and probably far from average. If you ace it, that's also unique and far from average. So when you hear that this test was 4 Standard Deviations from average, that means it falls out the range of what a ton of people got. Lower number means less unique. When you actually calculate a value for Standard Deviation is, the units are the same as what you're measuring. So here it's seconds. C) Variance is squaring the standard deviation. That means the units are the square of what the standard deviation was in. In this case, seconds squared. D) Median can be taken to mean "middle". So the "middle" age of the subjects was in units of? (what else do you measure age in?). If you look up the formulas for each and stick in units, and then know how to do algebra for the units, you can understand the answers better (for units anyway). Example: Find the average of these numbers: 5a, 5a, 5a, 5a You would add them all 5a + 5a + 5a +5a = 20a and then divide how many there were. 20a / 4 = 5a Units are like a variable. If you were to replace the variable "a" with "feet" and measure the average height of let's say those 4 people, you'd stick in feet where there was "a" and get the average to be 5 feet. Units follow the same algebraic rules as variables. So if you were to look up standard deviation and variance formulas, stick in units with the measurements, and then do the right algebra with the units (squaring, square rooting), you'll clearly see what the final units for those statistical quantities are.
Guys help im really bad at math can i still be a commercial Pilot?
Piloting planes is not "rocket science". If you can do basic math like addition, subtraction, multiplication, division and percentages, that's all you need. While most everything (including exams) can be done with a calculator, it's really helpful to be able to do basic calculations in your head quickly for some things. Such as: Example 1: you're at 30,000 feet and you have been cleared to descend and cross a fix thats 100 miles ahead at 10,000 feet, and your speed is 300 knots. What does your descent rate have to be in order to make the crossing restriction? Answer 1: Lets see, 300 knots per hour divided by 60 (60 mins in an hour) is 5 miles per minute. The fix is 100 miles ahead, so you'll cover that distance 20 minutes (100 divided by 5). You need to descend a total of 20,000 feet (30,000 - 10,000) and do it in that 20 minute time frame. Gee, 20,000 divided by 20 = 1000 feet per minute descent rate. This is a very typical real-life problem for a pilot. Not hard at all. What if the numbers aren't easy ones like in my example? Maybe the distance is 112 miles, or the altitude change is 17,000 feet, or your speed is 285 knots. You estimate, by rounding off to numbers that are easy to work with (such as 20,000, 100 and 300) and then recalculate 10 minutes later as needed. In fact being able to ESTIMATE an answer with reasonable accuracy is an extremely useful skill. On a written exam, answers need to be exact, but in real life applications being able to estimate is a more useful skill. Don't worry. You'll do fine. It just takes a little practice. As far as a college degree, take something that requires minimal math if you're hopelessly unable to grasp more advanced math concepts. Something like an Aeronautical Science degree will require you to take algebra and beginning calculus, and physics, but you don't really need such a degree to be a commercial pilot. In fact, the airlines don't really care what kind of degree you have as long as you have one, even if it's a degree in music.
I'm really bad at maths. Like unbelievably bad. Do I have any chance in heaven at an investment bank or hedge fund?
So I'm guessing you want to study finance or economics (there are many different functions at an investment bank, and a hedge fund). That being said, if you could elaborate more about what kind of roles interest you, I think you'll receive better and clearer answers from the Quora community.However, I'll assume you plan on studying finance or economics for now. As a finance major myself, finance is relatively easy and not as quantitative as you may think (especially when compared to mathematics or a computer science major), which I would find to be far more useful if you plan on doing HFT or anything of the like.You should have no problems plugging in math into financial calculators to do the computational formulas for you, therefore I think you stand a good chance if you go to a college or a university and pursue a business major (more so Finance or Economics). I will say this though, I am almost graduating and I found that most ivy business graduates have a much easier time getting into these kind of gigs. I am not trying to discourage you from pursuing finance, but it will be tough, and more so if you are not a STEM major.Best of Luck!
How long should I study for my math class if I’m really bad in math?
How long should I study for my math class if I’m really bad in math?At the risk of sounding facetious, as long as it takes.But remember that when it comes to studying it’s quality, not quantity that counts. Or, to put it another way, “It’s not the hours you put in but it’s what you put in the hours”.First thing to remember - studying is very much an individual thing. What works for one student might very well not work for another. Some students have to write things down so the concept sticks. Others have to say it aloud. Still others have to walk around while reading the material. And some just have to do something - I know one of my daughter’s grade school teachers used to hand out pieces of “mounting putty” at the start of each class to those students who regularly fidgeted - gave them something to do with their hands without bothering anyone else. Figure out what works for you.The usual holds - go to class, take notes, work on your assignments. Since you’re asking the question here it’s probably safe to say you’re already doing that.If you’re stuck on a concept ask your teacher. Whether it’s a question in class or after school hours. They’ll generally be more than willing to help you.And remember - THERE IS NO SUCH THING AS A STUPID QUESTION! If you don’t understand something odds are much of the rest of the class is in the same boat.And another point - math is very much a “cumulative subject”. That is, if you don’t understand the material you were supposed to learn last year you’re going to have troubles learning this year’s material - all the more reason to speak to your teacher.BTW, if your school runs some sort of “academic assistance” or “math drop in center” use it (those are just rooms staffed by a rotating group of teachers who are there to help you - sometimes just hearing something explained a different way is all it takes). I know both my kid’s high schools had some variant of this and the universities I attended (as both an undergrad and grad student) ran something similar - there they were staffed by graduate students.Good luck
System of Equations, I'm really bad at math?
I've had people try to explain it but all they did was do some equations without explaining why they did this and that. How would you be able to find the equations and in what order would you put them in? Someone please help, thank you. 1. A grocer carries two brands of coffee, one worth $5.50/kg and the other worth $6.50/kg. How many kilograms of each brand should be mixed together to produce 44kg of coffee worth $5.75/kg? 2. A beverage machine contains 59 nickles and dimes for a total of $4.55. How many of each coin does the machine contain? 3. Mimi is third as old as George. In 5 years, she will be one half as old as George. How old is Mimi?
