PLEASE HELP !!! - after tip you gave a total of $321.75. If the original price of the meal was $300, what percent tip was applie
yan [13]

Answer: 7.25%

Step-by-step explanation:

There are a few ways to do this, but the easiest might be to set up a proportion:

321.75/300 = x percent/100 percent

Now cross multiply;

300x = 321.75(100) = 32,175

Divide both sides by 300 to solve for x:

300x/300 = 32,175/300

x = 107.25 This means that the tip was 7.25% on top of the $300 meal.

Tính đạo hàm của y=2x-1-căn3x-0
adoni [48]

Answer:

The derivative is

\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\

Step-by-step explanation:

The function is given by

y = 2x - 1 - \sqrt {3x}

Differentiate with respect to x, we get

\frac{dy}{dx} = 2 - 0 - \frac{2\sqrt3}{\sqrt x}\\\\\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\
