The 8th term of a GP is -7/32 find its common ratio if its first term is 28
Ugo [173]
<h2>Common ratio = -1/2</h2>

Step-by-step explanation:

       \text{8}^{th} term of a Geometric progression is given as \dfrac{-7}{32}. The first term is given as 28.

       Any general Geometric progression can be represented using the series a,ar,ar^{2},ar^{3},ar^{4}...\text{ }ar^{n-1}.

The first term in such a GP is given by a, common ratio by r, and the n^{th} term is given by ar^{n-1}.

       In the given GP, a=28;t_{8}=ar^{7}=\dfrac{-7}{32}\\\\28r^{7}=\dfrac{-7}{32}\\\\r^{7}=\dfrac{-1}{128}\\\\r=\dfrac{-1}{2}

∴ Common ratio is \dfrac{-1}{2}.

Patricia, Luca and Dauda shared an amount of money such that, Patricia had twice as much
inn [45]

Answer:

GH 1533

Step-by-step explanation:

Let Dauda's share of the money=x

Patricia had twice as much  as Dauda, therefore:

Patricia's share=2x

Luca had GH 600.00 more than Dauda, therefore:

Luca's Share =x+600

If Patricia had GH 2,000.00

Then: 2x=2000

x=1000

Therefore:

  • Dauda's Share=GH 1000
  • Patricia's share=GH 2000
  • Luca's Share =1000+600=GH 1,600

Next, we determine the average share.

\text{Average Share=}\dfrac{1000+2000+1600}{3}\\=\dfrac{4600}{3}\\\\=$GH 1533.33\\\text{Average Share} \approx $GH 1533 (to the nearest GH)

Sheila is moving to a new house. She rents a truck with a storage body as shown below.
patriot [66]

Answer:

volume of the storage body is 576. multiply by 9. she can fit 64 boxes

Step-by-step explanation:

so draw a line at the short end of the body so it would be 6ft x 4 ft x 2ft = 48 ft. then the rest of the body becomes 11 ft (15 ft minus 4 ft) x 8ft x 6ft =528. so 48 + 528 = 576 then you divide 576 by 9 and get 64.
