Because the paper is folded diagonally, you already know the two straight side lengths but not the diagonal. The triangle is a right triangle so you van use the Pythagorean Theorem to find the diagonal. The Pythagorean Theorem = a^2+b^2=c^2 so 8.5^2+8.5^2=144.5^2 144.5^2=12.02 The diagonal of the right triangle would then be 12.02 inches. Hope this helps!!

Pythagorean Theorem!

$a^{2}$ + $b^{2}$ = $c^{2}$
$8.5^{2}*8.5^{2}= c^{2}$
72.25+72.25= $c^{2}$
144.5= $c^{2}$
$\sqrt{144.5}$
12.02 or just 12

A submarine sits at –300 meters in relation to sea level. Then it descends 115 meters. What is its new position in relation to s

avanturin [10]

Answer:

$New\ Position = -415m$

Step-by-step explanation:

Given

$Position= -300m$

$Descend = 115m$

Required

Determine the new position

It descends means that it moved in the downward position.

So, the new position is:

$New\ Position = Position - Descend$

$New\ Position = -300m - 115m$

$New\ Position = -415m$

<em>Hence, the new position f the submarin is -415m</em>

The correct answer is that Hector placed Puppy 3 at -3.4 instead of at -0.75.
So A would be your correct answer. -3/4 is equivalent to -0.75. Think of it like money. 4 quarters equals $1.00. 3 quarters is 75 cents, or .75 which is this. Don’t forget the signs though. God bless you.

(x+16)²=12 plz help me and show work

Answer:

The answer is $x=-16$ ± $2\sqrt{3}$ in exact form or $x=-12.535898$ , $x=-19.464102$ in decimal form.

Step-by-step explanation:

To solve this problem, start by moving all terms to the left side of the equation and simplify. Simplify the equation by subtracting 12 from both sides of the equation and squaring $x+16$ , which will look like $x^{2} +32x+256-12=0$ . Next, simplify the equation again, which will look like $x^{2} +32x+244=0$ .

Then, use the quadratic formula to find the solutions. The quadratic formula looks like $\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}$ .

For this problem, the quadratic variables are as follows:

$a=1$

$b=32$

$c=244$

The next step is to substitute the values $a=1$ , $b=32$ , and $c=244$ into the quadratic formula and solve. The quadratic formula will look like $\frac{-32(+-)\sqrt{32^2-4(1*244)} }{2*1}$ . To simplify the equation, start by simplifying the numerator, which will look like $x=\frac{-32(+-)4\sqrt{3} }{2*1}$ . Then, multiply 2 by 1 and simplify the equation, which will look like $x=-16(+-)2\sqrt{3}$ . The final answer is $x=-16$ ± $2\sqrt{3}$ in exact form. In decimal form, the final answer is $x=-12.535898$ , $x=-19.464102$ .
