Question one answer: S²=3V/H

Mathematics
1 answer:
FinnZ [79.3K]3 years ago
3 0

Answer:

\ S=\sqrt{\dfrac{3V}{H}}}

Step-by-step explanation:

The opposite operation of squaring is taking the square root.

\ S=\sqrt{\dfrac{3V}{H}}}

We know that the denominator of a fractional power is the index of the corresponding root:

\displaystyle x^\frac{1}{n}=\sqrt[n]{x}

For n=2, we don't usually write the index in the root symbol:

x^{\frac{1}{2}}=\sqrt{x}

In the case of this problem, ...

(S^2)^{\frac{1}{2}}=\left(\dfrac{3V}{H}\right)^{\frac{1}{2}}\\\\S=\sqrt{\dfrac{3V}{H}}

Bill and Sam go to a casino. They each have the same amour of money. After an hour bill had won $20 and Sam lost the same amount
Pachacha [2.7K]

Answer:

They each have $180 before they started.

Step-by-step explanation:

Let x represents the amount they each have before they started. Therefore, we have:

Amount with Bill after one hour = x + $20

Amount with Sam after one hour = x - $20

Amount with Bill after two hours = (x + $20) - (x + $20)(2 / 3)

Amount with Sam after two hours = (x - $20) + (x - $20)(2 / 3) = 4((x + $20) - (x + $20)(2 / 3)) ............... (1)

From equation (1), we can solve for x as follows:

(x - $20) + (x - $20)(2 / 3) = 4((x + $20) - (x + $20)(2 / 3))

(x - $20) + (x - $20)0.666666666666667= 4((x + $20) - (x + $20) 0.666666666666667)

x - $20 + 0.666666666666667x - $13.3333333333333= 4(x + $20 - 0.666666666666667x - $13.3333333333333)

x - $20 + 0.666666666666667x - $13.3333333333333= 4x + $80 - 2.66666666666667x - $ 53.3333333333332

Collecting the like terms, we have:

x + 0.666666666666667x - 4x + 2.66666666666667x = $80 - $53.3333333333332+ $20 + $13.3333333333333

(1 + 0.666666666666667- 4 + 2.66666666666667)x = $60

0.333333333333337x = $60

x = $60 / 0.333333333333337

x = $180

Therefore, they each have $180 before they started.
