Correct Answer: Option A

Principal Amount = P = $23,400
Interest rate = r = 3% = 0.03
Time = t = 10
Number of compounding periods in a year = n = 2
Compounded amount = A = ?

Formula for compound interest is:

A = P(1+ \frac{r}{n} )^{t*n}

Using the values, we get:

A=23400(1+ \frac{0.03}{2})^{2*10}=31516.41

Option A is the closest one, so its the correct answer

Can I please get some help?? Use the diagram and the given information to find the unknown length.
Ostrovityanka [42]
The diagram shows that
AB = 5
AC = AB+BC = 5+2 = 7
DE = 7
DF = DE+EF = 7+x

So,
AB/AC = DE/DF
5/7 = 7/(7+x)
5(7+x) = 7*7
5(7+x) = 49
35+5x = 49
5x = 49-35
5x = 14
x = 14/5

So EF = 14/5 in fraction form
In decimal form, EF = 2.8 (since 14/5 = 2.8)

It costs $26 to fertilize, water, mow, and maintain each square yard of a full size FIFA field (with maximum dimensions) before
ElenaW [278]

Answer:

It will cost $256542 to prepare the field for next weeks match.

Step-by-step explanation:

The maximum dimensions of a field according to FIFA rules is 110 m by 75 m.

So, the maximum area of a field is (110 × 75) = 8250 square meters.

Now, 1 square meters is equivalent to 1.196 square yards.

So, the maximum area of a field is (8350 × 1.196) = 9867 square yards.

Now, given that it costs to make ready each square yard of a full-size FIFA field, $26 before each game.

Therefore, it will cost $(26 × 9867) = $256542 to prepare the field for next week's match. (Answer)
