It is rational/irrational

A rational number can be written in the form a/b where a and b are integers and b≠0

so

remember that √(a/b)=(√a)/(√b)

so $\sqrt{\frac{82}{20}}=\sqrt{\frac{41}{10}}=\frac{\sqrt{41}}{\sqrt{10}}\frac{\sqrt{410}}{10}$

we can't make it into a/b so it's irrational

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You

amid [387]

Answer:

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26

Hope this was helpful to you, and don't forget to choose the Brainliest answer!

Passing through (-2, 8) and PERPENDICULAR to y = 2x + 5

tangare [24]

Answer:

$y=\frac{-1}{2} x+7$

Step-by-step explanation:

The slope of a perpendicular line will always be the NEGATIVE RECIPROCAL of the slope of the original line.

y=2x+5

Because this equation is organized in slope-intercept form, y=mx+b, we can identify the slope of the original line is 2. The negative reciprocal of 2 is $\frac{-1}{2}$ . Therefore, the slope of the perpendicular line is $\frac{-1}{2}$ . So far, our equation looks like this:
