Step-by-step explanation:
Answer:
$ 10,376.45
Step-by-step explanation:
162,529 x 0.05= 8,126.45
8,126.45 + 2,250 = 10,376.45
Answer:
x=
16
333
y=
8
283
Step-by-step explanation:
1 Solve for yy in 13+2x+y+90=18013+2x+y+90=180.
y=-2x+77y=−2x+77
2 Substitute y=-2x+77y=−2x+77 into 4x+1+8x-2y=1804x+1+8x−2y=180.
16x-153=18016x−153=180
3 Solve for xx in 16x-153=18016x−153=180.
x=\frac{333}{16}x=
16
333
4 Substitute x=\frac{333}{16}x=
16
333
into y=-2x+77y=−2x+77.
y=\frac{283}{8}y=
8
283
5 Therefore,
\begin{aligned}&x=\frac{333}{16}\\&y=\frac{283}{8}\end{aligned}
x=
16
333
y=
8
283
Done
Use the sum of angles's trigonometric identity formula:
cos(A+B)=(cosAcosB-sinAsinB)
x+y=4cos(t+π/6)+2sint=4(cost*cosπ/6-sint*sinπ/6)+2sint
recall that cosπ//6=√3/2, and sinπ/6=1/2:
4(cost*cosπ/6-sint*sinπ/6)+2sint=4[(√3/2)cost-(1/2)sint]+2sint
simplify:2√3cost-2sint+2sint=2√3cost
<span>10% of 8350=$835.
15% of 25600(8350 from 33950) =25,600 15% of 25600= 3840.
25% of 3500. (32450 minus 33950= 3500 25% of 3500 =875.
Add the three and you get $5550. Of course you could have eliminated step two and three by anticipating a tax that far exceeded the other choices which were way to low to even consider.
Work this out for yourself. It is simple and fun when you get the hang of it.
