When is the value of a fraction less than 1?
Any time the numerator is smaller than the denominator.
How do you find the product or quotient using positive exponents when you have negative ones?
Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.
What is the quotient rule in algebra?
Any time you have a variable in the numerator or denominator in an equation, you multiply by the number where ever its on the fraction to both sides of the equation.
Can you only divide a numerator and denominator one time when finding the simplest form?
If you are dividing them by their GCF, one time is all that will be necessary. If not, it may take more tries.
What percent is 15 over 20?
15/20 =75/100 or 75%Why?What you do with the denominator is what you do with the numerator. Since 100/20 (100 divided by 20) = 5 then you multiply the denominator (20) by 5 which is obviously 100 and the numerator by 5 too and you get 75. 75/100 is 75%. Look at the work below.15 time 5 = 75--- --- = ---20 time 5 = 100
How do you calculate the time constant for a simple series RL circuit?
The time constant of an RL series circuit is calculated using the formular: time constant=L/R
Is time the numerator or denominator in division?
It can be either. The answer to this question depends on the context of the question.
When is the value of a fraction less than 1?
Any time the numerator is smaller than the denominator.
Can 560 1000s be reduced?
Yes, any time you have a numerator and a denominator that can be divided evenly by the same number it can be reduced. If you devide the numerator (560) and the denominator (1000) both by 8, you end up with 560/1000 = 70/125.
How do you calculate the time constant in a series resistor?
A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.
Time constant of LC circuit is?
T=sqrtLC
What is denomirator?
When you have a number (or a function) written in the form a/b then b is the denominator (a is the numerator). a nd b may be numbers or variables. For example, in the equation: velocity = distance/time, time is the denominator.
Time constant of an RC circuit increases if the value of the resistance is?
Answer : increase The time required to charge a capacitor to 63 percent (actually 63.2 percent) of full charge or to discharge it to 37 percent (actually 36.8 percent) of its initial voltage is known as the TIME CONSTANT (TC) of the circuit. Figure 3-11. - RC time constant. The value of the time constant in seconds is equal to the product of the circuit resistance in ohms and the circuit capacitance in farads. The value of one time constant is expressed mathematically as t = RC.
Mix number to improper fraction?
You multiply the whole number by the denominator, then whatever that answer is you add the nominator to it. Then that's your new nominator. But the denominator in the mixed number is still the denominator.
Time constant of an RC circuit increases if the value of the resistance?
Increased The time constant of an "RC" circuit IS RC. So it's directly proportional to 'R' and also directly proportional to 'C'.
An RC circuit has a time constant of 10ms and an applied voltage of 15V What is the voltage on the capacitor after one time constant?
About 5.5 volts.
How do you find the product or quotient using positive exponents when you have negative ones?
Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.
