Answer:

4/6 chance

One is taken at random, we do not know the colour so we just take away 1 from both colours, this leaves us with 4/6 chance.

Hazlina had some money, she spend 3/8 of her money and left $60, how much money did she spend?

leonid [27]

She spent 3/8x=60 so x= (60*8)/3 = $160 total spent. Hope this helps show how to put into equation form and solve for your unknown value. Thank you! Please rate if I helped you understand the concept! Thanks again!

11. Any company plans to connect a total of 20 pF of capacitance to a 7200-V

vesna_86 [32]

Answer:

C = 80pF

Step-by-step explanation:

The total capacitance of 4 capacitors connected in series is given by:

$Ct = \frac{1}{1/C1 + /C2 + 1/C3 + 1/C4}$

$Ct = \frac{1}{1/C + /C + 1/C + 1/C}$

$Ct = \frac{1}{4/C}$

$Ct = \frac{C}{4}=20pF$

Solving for C:

C = 4*20pF

C = 80pF

How do I simplify ((3x^2+12x+12)/(2x^2+x-6))/((4x^2-9)/(3x^3+x^2-10))

Shalnov [3]

$\dfrac{ \frac{3x^2+12x+12}{2x^2+x-6} }{ \frac{4x^2-9 }{3x^3+x^2-10} } =$

$= \dfrac{3(x + 2)^2}{(2x - 3)(x + 2)} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)}{2x - 3} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)(3x^3+x^2-10) }{(2x - 3)^2(2x + 3)}$
