Answer:
Approximately 104 joggers are female
Step-by-step explanation:
The U.S census bureau reported that 9 out of every 20 joggers at female.
Let x be the number of females out of 230 joggers.
Rewrite it as
Now we can write a proportion:
Cross multiply:
![20x=9\cdot 230\\ \\2x=9\cdot 23\ [\text{Divided by 10}]\\ \\x=\dfrac{9\cdot 23}{2}=\dfrac{207}{2}=103.5\approx 104](https://tex.z-dn.net/?f=20x%3D9%5Ccdot%20230%5C%5C%20%5C%5C2x%3D9%5Ccdot%2023%5C%20%5B%5Ctext%7BDivided%20by%2010%7D%5D%5C%5C%20%5C%5Cx%3D%5Cdfrac%7B9%5Ccdot%2023%7D%7B2%7D%3D%5Cdfrac%7B207%7D%7B2%7D%3D103.5%5Capprox%20104)
Answer:
I think so yeah. not sure though
Answer:
-24v + 8 by the distributive property
Step-by-step explanation:
Start by multiplying 6v by -4

Step-by-step explanation:</h2>
Scientific notation is a special way we choose for writing numbers. So the numers 
are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:
![\frac{6.47}{3.36}\times 10^{[-15-(-29)]}=1.92559524\times 10^{(-15+29)} \\ \\ \therefore 1.92559524\times 10^{14} \ or \ \boxed{1.92559524e+14}](https://tex.z-dn.net/?f=%5Cfrac%7B6.47%7D%7B3.36%7D%5Ctimes%2010%5E%7B%5B-15-%28-29%29%5D%7D%3D1.92559524%5Ctimes%2010%5E%7B%28-15%2B29%29%7D%20%5C%5C%20%5C%5C%20%5Ctherefore%201.92559524%5Ctimes%2010%5E%7B14%7D%20%5C%20or%20%5C%20%5Cboxed%7B1.92559524e%2B14%7D)
The division has been performed using the rules for operation with exponentiation.
