Increase £64 by 70%??????

olya-2409 [2.1K]

I'm not sure if you used the euro sign accidentally or what but this is how to increase 64 by 70%

divide 64 by 10.
6.40
then multiply it by 7.
44.80
then add 44.8 to your original number. (64)
the answer is:
108.8

If you did put that sign there purposely and if it means something then I don't know if it matters or if this is right.

A series RLC circuit contains an inductor with a value of 200 millihenries and a capacitor with a value of 0.1 microfarad. What

vaieri [72.5K]

Answer:

1125.4 Hz

Step-by-step explanation:

The resonant frequency is the frequency at with the inductive reactance is equal to the capacitive reactance. It is given by the relation ...

$f=\dfrac{1}{2\pi\sqrt{LC}}$

where L is in henries, and C is in farads.

For the given circuit values, the resonant frequency is ...

$f=\dfrac{1}{2\pi\sqrt{0.2\cdot0.1\times10^{-6}}}\approx1125.4$

The resonant frequency of this circuit is about 1125.4 hertz.

Which of the following is the product of the rational expressions shown

Alexus [3.1K]

Answer: x = 0; x=10

Step-by-step explanation:

$\frac{x+2}{x-4} *\frac{3x}{x+4}\\ \\x+2(x+4) = x-4(3x)\\x^{2} +2x+ 4x + 8 = 3x^{2} -12x\\2x+4x+12x =3x^{2} - x^{2} \\20x= 2x^{2} \\10x = x^2\\x=0\\x=10$

Hope this helps!
