0.3722
0.38
0.3886

Notice all have a 3 after the decimal so look to the next number.
Seven is smaller than 8.
Look to the next number, 0 (or no number) is less than 8

27. (-2 + √-8) + (5 - √-50) standard form ?

marin [14]

We can break this down by removing the parenthesis first:

-2 + $\sqrt{-8}$ + 5 - $\sqrt{-50}$

In order to continue, you have to simplify the square roots by factoring it and taking out i:

-2 + $2i\sqrt{2}$ + 5 - $5i\sqrt{2}$

Combine like terms:

-3 - $3i\sqrt{2}$ <-- that's the answer

Hope I helped :)

An architect is designing a house for the Frazier family. The Fraziers have asked that the cost of

PolarNik [594]

Answer:

║x - 175,000║≤ 20,000

Step-by-step explanation:

Let x be the amount the Fraziers are willing to pay. Since the house costs $175,000 and they are willing to deviate from this price no more than $20,000, so x = $175,000 ± $20,000.

So, x - 175,000 = ± 20000

║x - 175,000║= 20,000

But we require

║x - 175,000║≤ 20,000

which is our required open sentence.

How do you write equation for rise ove run

SashulF [63]

Y = mx + b

M= your slope or rise over run

B = your y-intercept

For example if the rise was 5 and the run is 6, the equation would say
y = 5/6 + b
The / being your fraction bar

The y-intercept is where your line crosses the y-axis
So say that the line crosses the y-axis at 10
y = 5/6 + 10

That about sums it all up!

Can someone tell me step by step how to solve this?

sasho [114]

Answer:

Step-by-step explanation:

I take it that this is some sort of ratio. Start by solving the brackets on the left.

Brackets: 1/3 - 1/10

Brackets: 10/30 - 3/30

Brackets: 7/30

Brackets^2: 49/900

Brackets^2 - 1/5: 49/900 - 180/900

Brackets^2 - 1/5: -131/900

(2/5)^2 = 4/25

The way this read, it should be

$\frac{\frac{-131}{900} }{\frac{4}{25} }$

Which when you invert and multiply becomes

$\frac{-131}{900} * \frac{25}{4}$

which finally becomes

$\frac{-131}{144}$
