Find the payment necessary to amortize a 6.3% loan of 7500 compounded semiannually, with 6 semiannual payments. Find the payment

Lorico [155]

Answer:

Semiannual payment = $ 1391.37

Total payment = $ 8348.22

Interest paid = $ 848.22

Step-by-step explanation:

Since, the semiannual payment formula of a loan,

$P=\frac{PV(\frac{r}{2})}{1-(1+\frac{r}{2})^{-n}}$

Where,

PV = present value of the loan,

n = number of semiannual payments,

r = annual rate,

Here, PV = 7500, r = 6.3% =0.063, n = 6,

By substituting the value,

The semiannual payment would be,

$P=\frac{7500(\frac{0.063}{2})}{1-(1+\frac{0.063}{2})^{-6}}$

$\approx \$ 1391.37$

Also, total payment = semiannual payment × total semiannual periods

= 1391.37 × 6

= $ 8348.22,

Also, the interest paid = total payment - present value

= 8348.22 - 7500

= $ 848.22

What is the most accurate representation of the area of a plot measuring 11.7 cm by 15.4 cm?

sergiy2304 [10]

In the given question the length and width of the plot are already given. although there is no direct specification regarding the one that is length or the one that is the width, so it can be taken as your own choice. This will not affect the ultimate answer.
So
Area of the rectangular plot = Length * Width
= 11.7 * 15.4 square cm
= 180.18 square cm
So the area of the rectangular plot as can be seen from the above deduction is 180.18 square centimeter.

On a blueprint, the scale says that 2 cm represents 3 m. What is the actual length of a wall if its measurement on the blueprint

Leokris [45]

Answer:

The actual length of the wall is 10.5 m

Step-by-step explanation:

Write and solve an equation of ratios to answer this question:

2 cm 3 m

--------- = ---------

7 cm L

Solve this for L by inverting both sides:

7cm L

---------- = --------

2 cm 3 m

and then multiplying both sides by 3m:

----- = L

The actual length of the wall is 10.5 m
