1/8 is the answer
7/8+1/8=1
Answer:
C. 50.24 feet
Step-by-step explanation:
The formula for circumference is 2rπ (two times radius times pi)
2 * 8 * 3.14 = 50.24
Answer:
D) log5(15)
Step-by-step explanation:
The relevant rule of logarithms is called the "change of base formula:"
![\log_b(a)=\dfrac{\log(a)}{\log(b)}](https://tex.z-dn.net/?f=%5Clog_b%28a%29%3D%5Cdfrac%7B%5Clog%28a%29%7D%7B%5Clog%28b%29%7D)
The logs on the right side of this equation can have any base, provided both have the same base.

Your expression can be simplified as follows:
![\dfrac{\log_5(m)}{\log_{15}(m)}=\dfrac{\left(\dfrac{\log(m)}{\log(5)}\right)}{\left(\dfrac{\log(m)}{\log(15)}\right)}=\dfrac{\log(15)}{\log(5)}=\boxed{\log_5(15)}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Clog_5%28m%29%7D%7B%5Clog_%7B15%7D%28m%29%7D%3D%5Cdfrac%7B%5Cleft%28%5Cdfrac%7B%5Clog%28m%29%7D%7B%5Clog%285%29%7D%5Cright%29%7D%7B%5Cleft%28%5Cdfrac%7B%5Clog%28m%29%7D%7B%5Clog%2815%29%7D%5Cright%29%7D%3D%5Cdfrac%7B%5Clog%2815%29%7D%7B%5Clog%285%29%7D%3D%5Cboxed%7B%5Clog_5%2815%29%7D)
housing: 900/4500 = 0.2 = 20%
transportation: 650 / 4500 = 0.14 = 14%
utilities: 120/4500 = 0.026 = 2.6% ( round to 3% maybe)
food: 475/4500 = 0.105 = 10.5% (round to 11% maybe)
savings: 1600 / 4500 = 0.355 = 35.5% (round to 36% maybe)
Student Loan: 270 / 4500 = 0.06 = 6%
Other expenses: 485 / 4500 = 0.107 = 10.7% (round to 11% maybe)
You didn't say if they needed to be rounded so I gave you the options on the ones that may need it.
the answer would be the third choice which is N(0, z)
