What is the ratio of surface area to volume?

1 answer:

6 0

The ratio of surface area to volume is the amount of surface area per unit volume of a thing. This is an important value in various topics. In chemistry, this is an important value for chemical reactions. It can show reactivity of a solid material. Also, it has found some importance in biology because it shows how the cells are affected by the environment where that cell is found.<span />

Given:

4/5 of a pie left after their family picnic.

Each slice of pie was 1/15 of the total pie.

To find:

The number of remaining slices of pie.

Solution:

Let x be the number of remaining slices of pie.

Part of total pie in one slice = $\dfrac{1}{15}$

Remaining part of total pie in x slices = $\dfrac{1}{15}x$

According to the question, 4/5 of a pie left after their family picnic.

$\dfrac{1}{15}x=\dfrac{4}{5}$

Using cross multiplication, we get

$5\times x=15\times 4$

$5x=60$

Divide both sides by 5.

$x=12$

Therefore, the remaining number of slices of pie is 12.

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.

What is the greatest common factor (gcf) of the numerator and denominator in the rational expression below? 7x+14/2x^2+x-6

Mashutka [201]

The answer is C. The numerator 7x+14 can be factored as 7(x+2). The denominator 2x^2+2x-6 can be factored as (x+2)(2x-3). The greatest common divisor of 7(x+2) and (x+2)(2x-3) is obviously x+2, which is contained in both of the two expressions.
