Answer:

Option A.

Step-by-step explanation:

we have

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

Simplify the right side of the equation

we know that

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

so

The expression is

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

therefore

x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a

Here are 946 milliliters in a quart. There are 22 pints in a quart. How many milliliters are in a pint?
Fed [463]

Answer:  The answer is 43.


Step-by-step explanation:  Given that there is a quart, in which there are 946 millilitres and 22 pints. We are to find how many millilitres are there in a pint.

For that, we just need to divide number of milliliters by the number of pints in the quart.

Let us start as follows -

In 22 pints of the quart = 946 millilitres.

Therefore, in 1 pint of the quart = 946/22 = 43 millilitres.
