Equipment was purchased for $85,000 on january 1, 2015. freight charges amounted to $3,500 and there was a cost of $10,000 for b
Elena-2011 [213]
85000+3500+10000=98500 is a historic price of equipment. Annual depreciation is (98500-15000)/5=83500/5=16700. At december 31 2016 will be gone 2 years-2015 and 2016. So the accumulated depreciation will be 2*16700=33400

If r = 4 and ^a8 = 100, what is the first term of the geometric<br> sequence?
telo118 [61]

The first term of the geometric  sequence is 0.0061

<u>Step-by-step explanation:</u>

The general form of geometric  sequence is a, ar, ar²,ar³,.......

where,

  • a is the first term of the sequence.
  • r is the common ratio. Here, the common ratio r = 4.
  • The 8th term of the sequence is 100. Hence n = 8.

<u>The formula to find the nth term of the geometric sequence is given by :</u>

⇒ n_{th} term = ar^{n-1}

⇒ 8_{th}term  = a\times4^{8-1}

⇒ 100 = a \times 4^{7}

⇒ 100 = a \times 16384

⇒ a = \frac{100}{16384}

⇒ a = 0.0061

Therefore, the first term of the geometric  sequence is 0.0061

Nick has some quarters and dimes. He has 17 coins worth a total of $3.35. How many of each type
kolbaska11 [484]
Equations:
q + d = 17
0.25q + 0.10d = 3.35$
———————
-0.10( q + d = 17)
-0.10q -0.10d = -1.7

-0.10q -0.10d = -1.7
0.25q + 0.10d = 3.35
Add the equations together
0.15q = 1.65
/0.15 on both sides
q = 11
———————
q + d = 17
11 + d = 17
-11 on both sides
d = 6
———————
0.25q + 0.10d = 3.35
0.25(11) + 0.10(6) = 3.35
2.75 + 0.60 = 3.35
3.35 = 3.35
———————
