pychu [463]
Knowing that an optimal shape is a cube is critical to solving this problem.  With you now having that in mind, each side of the cube has a length of 4 inches.  So the area of 1 face is 16 square units and the total surface area is 96 square units.

GC - If the principal amount of money put into a bank is $2000 with a 3.5% rate compounded quarterly, what is the amount after 6
alisha [4.7K]

Given:

Principal amount = $2000

Rate of interest = 3.5% compounded quarterly.

Time = 6 years

To find:

The amount after 6 years.

Solution:

The formula for amount after compound interest is:

A=P\left(1+\dfrac{r}{n}\right)^{nt}

Where, P is principal, r is rate of interest in decimal, n is the number of time interest compounded in an year and t is the number of years.

The interest is compounded quarterly, so n=4.

Substituting P=2000,r=0.035,n=4,t=6, we get

A=2000\left(1+\dfrac{0.035}{4}\right)^{4(6)}

A=2000\left(1+0.00875\right)^{24}

A=2000\left(1.00875\right)^{24}

A=2465.10340

Approximate the value to the nearest hundredth.

A\approx 2465.10

The amount after 6 years us $2465.10. Therefore, the correct option is A.

Trava [24]

Answer:

The answer is 10x - 10y - 9

Step-by-step explanation:

14 - 3 - 20 = -9

2y - 12y = -10y

7x + 3x = 10x

14 + 2y - 3 + 7x - 12y + 3x - 20 = 10x - 10y - 9
