Step-by-step explanation:
24% = 156
1% = 24%/24 = 156/24 = 6.5
100% = 1%×100 = 6.5×100 = 650
so, 650 students were surveyed.
Answer:
$367.87
Step-by-step explanation:
![P[(1 + r/100n)]^nt](https://tex.z-dn.net/?f=P%5B%281%20%2B%20r%2F100n%29%5D%5Ent)
![(2300)[(1 + (2.12)/100n)]^(52)(7)](https://tex.z-dn.net/?f=%282300%29%5B%281%20%2B%20%282.12%29%2F100n%29%5D%5E%2852%29%287%29)
You would do 7/8 x 8/1 which is 56/8 which simplifys to 7 so your answer would be 7
4/(m+9)+5/(m^2-81)=
4/ ( m+9) +5 / ( m-9)(m+9)=
4(m-9)/(m+9)(m-9)+ 5 / (m+9)(m-9)=
(4m-36+5)/(m+9)(m-9)=
4m-31/ (m+9)(m-9)
the answer is D
