John invested $17,500 that

babymother [125]

Answer:

<u>The future value of the investment after 10 years is $ 29,240.53</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Principal = $ 17,500

Interest rate = 5.2% = 0.052 compounded semiannually

Time = 10 years = 20 semesters

2. What is the future value of the investment after 10 years?

Let's use the formula of the Future Value, to calculate it for this investment:

FV = P * (1 + r) ⁿ

Let's replace with the real values:

FV = 17,500 * (1 + 0.052/2)²⁰

FV = 17,500 * 1.670887521

lisabon 2012 [21]

we are given:

Selling price=$40.00

Fixed cost=$72000.00

Cost per piece=$32.00

Let x products be sold to break-even then

$\\ \ 40x=7200+32x\\ \\ \ \Rightarrow 40x-32x=7200\\ \\ \ 8x=7200\Rightarrow x=\frac{7200}{8}=900\\$

Nemo's aquarium is filled with 2,4002{,}400 2,400 2, comma, 400 cubic centimeters of water. The base of the aquarium is 20 cm 20

kolezko [41]

The water in the aquarium is a rectangular prism with dimensions 20, 12 and h (where the height is unknown).

We know that the volume is the product of the dimensions, and that it is 2400, so we have

$V=2400=20\cdot 12 \cdot h \iff 240h=2400 \iff h=10$
