What single amount on April 1, 2012, is equivalent to a series of equal, semiannual cash flows of $5200 that starts with a cash fl
inysia [295]

The single amount on April 1, 2012 that is equivalent to a series of equal, semiannual cash flows of $5200 is; $57,023.2

<h3>Compound Interest Factor</h3>

We are given;

Semi annual cash Flow; A_sa = $5200

Interest rate; r = 6%

From April 1, 2012 to January 1 2019 is 6.75 years

Thus; Period; T = 6.75 years

Cash flows is semi annual. Thus; t_a = 1/2

Thus; n_sa = 6.75 * 2

n_sa = 13.5

i_sa = 6% * 1/4 = 1.5%

Thus;

Single amount = 5200 * (P/A, 1.5%, 13.5)

From compound interest tables, P/A at n = 13.5 and at i = 3% by interpolation gives 10.966. Thus;

Single amount = 5200 * 12.137

Single amount = $63,112.4

forsale [732]

Answer:

\large\boxed{V=192\pi}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

<em>r</em><em> - radius</em>

<em>H</em><em> - height</em>

<em />

We have a diameter <em>d = 8 → d = 2r → 2r = 8 → r = 4</em>

and <em>H = 12.</em>

<em></em>

Substitute:

V=\pi(4^2)(12)=\pi(16)(12)=192\pi

Jane made a mistake when writing down a mutliplication , and she multiplied by 54 instead of 45. Her answer was 198 more than it
BARSIC [14]

Answer:

22

Step-by-step explanation:

Given that:

Let number multiplied by 54 = x

Let output = y

x * 54 = y + 198

x * 45 = y

54x = y + 198 - - - (1)

45x = y - - - (2)

Put y = 45x in (1)

54x = 45x + 198

54x - 45x = 198

9x = 198

x = 22

Number multiplied by 54 is 22
