(5x - 2)(25x2 + 10x + 4)
(5x + y)(25x^2 - 5xy + y^2)
√125X² = 125X
The answer is 84128.
Power Factor is one of most significant parameter in calculating AC Power. As we know it is cosine of angle between AC Voltage and Current it comes in picture while calculating power in AC circuits Power In AC (P) = Voltage (V) X Current (V) X Power Factor Let us take an example of Power with Power factor and without power factor for same circuit. Let Us assume V = 125 Volts I = 1 Amp Power Factor = 1 Then P = 125X1X1= 125 Watts But for any circuit when Power factor is below 1, to execute same power, Circuit has to draw more current. for example P = 125X 1.25 X 0.8 = 125 Watts In first example power factor of the circuit was unity = 1 and in that condition current of the circuit was 1 amp whereas in second example power factor of the circuit is 0.8 due to which current of the circuit increases to 1.25 amp to execute the same power. Now due to increase in current of the circuit many factors are affected like heat loss, Conductor's specification , Class of insulation etc. Thus it can be concluded after going through above explanation that power factor play a significant role in AC power calculation as well as in actual practices.
5x^3 + 15 x^2 - 125x - 375 = 5(x^3 + 3 x^2 - 25x - 75) = 5[(x^3 + 3 x^2) - (25x + 75)] = 5[x^2(x + 3) - 25(x + 3)] = 5[(x + 3)(x^2 - 25)] = 5(x + 3)(x + 5)(x -5)
[ 125x3 + 8y3 ] is not a question or an equation, and it doesn't require an answeror a solution. It's simply an expression that represents a number. The value of thenumber depends on the values of 'x' and 'y', which of course you haven't included,and it changes in a flash any time either of them changes.
let x = number x - .125x = 420 .875x =420 x = 480
125x = .5x = 0.0044 thousandths of a foot
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
There can be no conversion.A foot is a measure of length in 1-dimensional space, whereas a square foot is a measure of area in 2-dimensional space. The two measure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
It is a bit difficult to be sure because I cannot see superscripts for the powers of x. x^4 + 3*x^3 + 125*x + 375 = x^3*(x+3) + 125*(x+3) =(x^3 + 125)*(x+3) And then using x^3+y^3 = (x+y)*(x^2-x*y+y^2) with y = 5 =(x+5)*(X^2-x+25)*(x+3)
If you are not allowd to cut any and you can disregard the width of the grout between the tiles: 125x = 55y , x and y are integers 5*25x = 5*11y 11*5*25 = 25*11*5 = 1375 A square 13.75 meters on each side using 275 tiles
use this equation to solve your problem. 80 125% __ = _____ X 100% 125x= 8000 ____ ____ 125 125 64 ________ 125| 8000 X= 64
Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1
Eugenia had five times as many quarters as dimes. If the total value of her coins was $16.20 how many of each kind of coin did she have?Let x= the amount of dimes Eugenia had (dimes are worth 10)Let 5x= the amount of quarters Eugenia had (quarters are worth 25)Equation: 10(x) + 25(5x)=1620 (because that is how many cents there are)10(x)+25(5x)=162010x+125x=1620135x=16201/135(135)=1/135(1620)1x= 12x=12check10(x) + 25(5x)=162010(12)+25(5x12)=1620120+25(60)=1620120+1500=16201620=1620x=125x=1500Therefore Eugenia had 12 dimes and 60 quarters
