What is the amount of a $4,000.00 annuity due at 12 percent compounded semiannually for 3 years?

Dmitriy789 [7]

Answer:

$ 5674.076

Step-by-step explanation:

The question is on compound interest

The formulae = A= P(1+ r/n) ^nt .......where P is the principal amount, r is the rate of interest in decimal, n is number of compoundings per year and t is the total number of years.

Given; P= $4,000.00 , r=12/100=0.12, n=2 and t=3

Substituting values in the equation A= P(1+ r/n) ^nt

A= 4000 ( 1+0.12/2)^2×3

A=4000(1.06)^6

A=$ 5674.08

Which expression is equivalent to a^m divide a^n?(20points)

Citrus2011 [14]

<h3><u>Answer</u> :</h3>

$\bigstar\:\boxed{\bf{\dfrac{a^m}{a^n}=a^{m-n}}}$

<h3><u>Learn More</u> :</h3>

$\dag\sf\:\:a^m\times a^n=a^{m+n}$

$\dag\sf\:\:\dfrac{a^m}{a^n}=a^{m-n}=\dfrac{1}{a^{n-m}}$

$\dag\sf\:\:a^{-m}=\dfrac{1}{a^m}$

$\dag\sf\:\:(a^{m})^n=a^{mn}$

$\dag\sf\:\:a^1=a$

$\dag\sf\:\:a^0=1$

$\dag\sf\:\:\sqrt[n]{a^m}=a^{\frac{m}{n}}$

The volume of 100 drops of a liquid is 0.1 fluid ounce.<br><br> What is the volume of 1000 drops?

Ket [755]

Hey there!

100 drops of the liquid is 0.1 fluid ounces.

1,000 is equal to 10 x 100.

To find the volume of 1,000 drops of liquid, we must multiply the volume of 100 drops, which is 0.1, by 10.

0.1 x 10 = 1

Therefore, the volume of 1,000 drops of this liquid is 1 fluid ounce.

Hope this helps!

A 15ftX20ft room has a 6ft diameter circular rug in it. How much of the flood is not covered by the rug?

Luda [366]

Answer:

There are 271.74 ft^2 not covered by the rug

The percentage not covered by the rug is 90.58%

Step-by-step explanation:

step 1

Find out the area of the room

The area of the rectangular room is

$A=(15)(20)=300\ ft^2$

step 2

Find out the area of the circular rug

The area of the circle is

$A=\pi r^{2}$

we have

$\pi =3.14$

$r=6/2=3\ ft$ ----> the radius is half the diameter

substitute

$A=(3.14)(3)^{2}$

$A=28.26\ ft^{2}$

step 3

Find out what percentage of the room is not covered by the rug

we know that

300 ft^2 represent the 100%

using proportion

Find out what percentage represent the difference (300-28.26)=271.74 ft^2

Let

x ----> the percentage not covered by the rug

$\frac{300}{100\%}=\frac{271.74}{x}\\\\x=100(271.74)/300\\\\x=90.58\%$

Convert to fraction form

$90.58\%=\frac{90.58}{100}$

Simplify

$\frac{4,529}{5,000}$

therefore

There are 271.74 ft^2 not covered by the rug

The percentage not covered by the rug is 90.58%
