What is the formula for the MA of a pulley?
The mechanical advantage (MA) of a pulley system is calculated using the formula: MA = Load Force / Effort Force. For a simple pulley, the MA is typically 1, as the effort needed to lift the load is equal to the load itself. However, in systems with multiple pulleys (block and tackle), the MA can equal the number of rope segments supporting the load. Thus, the more pulleys used, the greater the mechanical advantage.
Can 2 be a multiple of 8?
No, 8 is a multiple of 2, since it is 4 x2, but 2 is less than 8 so it can't be a multiple.
Are multiples of 9 also multiples of 3?
yes, every multiple of 9 is a multiple of 3, but that doesn't cover all of them ...there are more multiples of 3 besides those.
How many shares are there in a call option?
The standard is 100 shares. If you want more than 100 shares, you've got to buy multiple contracts. This has a big advantage: if you own 10 calls that will be profitable if the stock hits $15 per share and the stock hits $16.50, and you think it'll go higher, you can exercise some of the calls to lock in your profit, and hang onto some to try making more money.
What are the exact solutions for the equation cos2x - cosx equals 0?

What is an common multiple of the denominators for two or more fractions?
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
How is solving an equation that involves rational numbers similar to solving an equation that involves intergets?
If you multiply each term of the first type of equation by a common multiple of all the denominators then you will have an equation of the second type.For example, if you have 2/3*y = 4/5*x + 7/9 then multiplying by the LCM of 3, 5, 9) = 45, gives30*y = 39*x + 35: all integers!
Is the least common multiple of the denominators?
The least common denominator is the least common multiple of the denominators.
What is the lowest common multiple of the denominators?
You have to state the denominators to expect an answer
What is the common multiple of the denominators?
The least common multiple of the denominators is knows as the LCD or least common denominator.
How are a common denominator and common multiple different?
Common denominators are common multiples that are being used as denominators.

What is a number into which the denominators will divide evenly?
A multiple of the denominator.
How can you get a dcommon denominator?
You can multiply the two denominators, or you can find the least common multiple for the two denominators.
Adding and subtracting unlike denominators?
Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).
What is the best method for eliminating a fraction from an equation in point slope that is to be written in standard form?
There are actually several "standard forms" for line equations (point-slope form is one of them), so the exact details depend on which form you want.However, in general you can get rid of a fraction by multiplying all parts of the equation by the common denominator. For example, if somewhere in the equation you have a denominator of 5 (and no other denominators), you multiply everything by 5. That will get rid of the fraction.
