Answer:

2.3 hours, or 2 hours & 18 minutes

Step-by-step explanation:

we are trying to find h when d is 56.68, so I replaced d with 56.68

$56.68=24.6h+0.1\\$

subtract 0.1 from both sides

$56.58=24.6h$

divide both sides by 24.6

$2.3=h$

Answer:

35/132.

Step-by-step explanation:

There are a total of 12 balls. So:

Prob(First is green) = 5/12.

After the first selection there are 11 balls left.

Prob(The second is red) = 7/11.

The required probability = 5/12 * 7/11

= 35/132.

Note: the probabilities are multiplied because the 2 events are independent.

The steps to derive the quadratic formula are shown below:

Georgia [21]

Answer: $x+\frac{b}{2a}=\pm \frac{\sqrt{b^2 - 4ac}}{\sqrt{4a^2}}$

Step-by-step explanation:

We can rewrite the left hand side as a perfect square, more specifically

$\left(x+\frac{b}{2a} \right)^2$

So, taking the square root of both sides,

$x+\frac{b}{2a}=\pm \frac{\sqrt{b^2 - 4ac}}{\sqrt{4a^2}}$
