The circumference would be 53.38 because the formula on finding the circumference is pi times the diameter.

The formula for the circumference is 2 pi r. So you multiply 2 times pi times 8.5.

V-9/10v+6=11(hlp)this problem is confusing.

Valentin [98]

$\frac{v-9}{10v+6}=11 \\\\ 11(10v+6)=v-9 \\\\ 110v+66=v-9 \\\\ 110v-v=-9-66 \\\\ 109v= -75 \\\\ \boxed{v=-\frac{75}{109}}$

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where $a$ and $b$ are 2 legs of the triangle, and $c$ is the hypotenuse, aka the longest side of any triangle:

$a^2+b^2=c^2$

We know $a$ and $b$ and want $c$

$4^2+5^2=c^2$

$16+25=c^2$

$41=c^2$

Therefore, $c$ is approximately $6.403$

Factor with steps please!!!

myrzilka [38]

So you want to find two numbers that add up to -13 and multiply to 40. You can find the factors of 40 and find the pair that adds up to -13. -8 and -5 multiply to 40 and add up to -13.

(x−5)(x−8)=x2−13x+40

You can use foil to test it

x2+(−8x)+(−5x)+40=x2−13x+40

x2−13x+40=x2−13x+
