Answer:
$46
Step-by-step explanation:
40(0.15) = 6 (this is the amount of the tip)
40 + 6 = 46 (add the tip to the bill)
Answer:
9000
Step-by-step explanation:
the equation to figure this out would be 180(n-2). N would equal the number of sides so you would plug it in 180(52-2). Then you end up with 180*50 which equals 9000
The formula of the present value of annuity due:
![PV=C*[\frac{1-(1+i)^{-n}}{i}]*(1+i)](https://tex.z-dn.net/?f=PV%3DC%2A%5B%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%5D%2A%281%2Bi%29)
For your case:
C = $3000
i = 12% / 100 = 0.12
n = 3 * 2 = 6 (semiannually for 3 years means 6 payments)
So, the solution is:
![PV=3000*[\frac{1-(1+0.12)^{-6}}{0.12}]*(1+0.12)=3000*[\frac{1-0.5066}{0.12}]*1.12=](https://tex.z-dn.net/?f=PV%3D3000%2A%5B%5Cfrac%7B1-%281%2B0.12%29%5E%7B-6%7D%7D%7B0.12%7D%5D%2A%281%2B0.12%29%3D3000%2A%5B%5Cfrac%7B1-0.5066%7D%7B0.12%7D%5D%2A1.12%3D)
Answer: 405 yd squared
Step-by-step explanation:
V = (bh)/2
b = (15 x 9)/2 = 67.5
67.5 x 12 = 810
810/ 2 = 405
Answer:
3d - 4f
Step-by-step explanation:
(12d + 28f) - 5f - (27f + 9d)
12d + 28f - 5f - 27f - 9d
(12-9)d + (28-5-27)f
3d - 4f
don't forget to put bracket, it is fundamental
