I would say there is 18 girls in the club b/c the ratio is 3:4 there would be one more group of boys than girls. you divide 24 by y and you then subtract 6 from 24 to get 18.
I think that the answer would be 650. I’m not that good at this stuff
Answer:
○ ![\displaystyle \textcolor{black}{C.}\:\sqrt{193}\:km.](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ctextcolor%7Bblack%7D%7BC.%7D%5C%3A%5Csqrt%7B193%7D%5C%3Akm.)
Step-by-step explanation:
Use the Pythagorean Theorem to define the hypotenuse:
![\displaystyle a^2 + b^2 = c^2 \\ \\ 7^2 + 12^2 = x^2 \hookrightarrow 49 + 144 = x^2 \hookrightarrow \sqrt{193} = \sqrt{x^2} \\ \\ \boxed{\sqrt{193} = x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%5E2%20%2B%20b%5E2%20%3D%20c%5E2%20%5C%5C%20%5C%5C%207%5E2%20%2B%2012%5E2%20%3D%20x%5E2%20%5Chookrightarrow%2049%20%2B%20144%20%3D%20x%5E2%20%5Chookrightarrow%20%5Csqrt%7B193%7D%20%3D%20%5Csqrt%7Bx%5E2%7D%20%5C%5C%20%5C%5C%20%5Cboxed%7B%5Csqrt%7B193%7D%20%3D%20x%7D)

The standard form of a geometric sequence is
. We are told that the first number in the sequence is 5 and the second number is -10. Geometric sequences rely on that r to be a common ratio which is a muliplier. So to get from 5 to -10 we have to multiply by -2. That means that r = -2. Our formula then is
and any value could be subbed in for n to find that specific number in the sequence. A geometric sequence may be thought of as an exponential function whose domain is the set of natural numbers.
