Solve:-

-√127 = ?
-√127 = -11.2694276695846449

The answer to this is irrational because this number goes on and on forever and it can not be expressed as a ratio, so your answer is irrational.

Its irrational because the square root of 127 is a decimal that goes on and on and cannot be represented as a fraction. So it is irrational.

The length of a rectangle is 6 inches longer than it’s width what are the possible widths if the area of the rectangle is at lea
stealth61 [152]

Let the width = x

length = x + 6

(x + 6) * x = 667

Simplify

x² + 6 = 667

x² + 6 (-6) = 667 (-6)

x² = 661

√x² = √661

x = √661

x = 25.71 (rounded)

25.71 in. is your width

hope this helps

You earn $7.50 per hour at a fast food restaurant. You earned $123.75 last week. How many hours did you work last week?
ladessa [460]
I believe you would need to divide 123.75 by 7.50.

The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours

If one can of paint contains 2 2/5 gallons, how much paint is in one dozen cans of paint?
olasank [31]
Hi there!

Let’s take a look at the question.

One can of paint contains 2 2/5. We can make it easier by transforming the fraction (2 2/5) to a decimal (2.4). Now you have 2.4. Next, it says “one dozen”. One dozen refers to 12 cans. You’ll want to multiply 2.4 with 12.

Your answer is 28.8, or 28 4/5.


Hope this helps!
