Mathematics
1 answer:

5 0

the volume of the cube is: 512 cubic feet

Step-by-step explanation:

Given

Length = l = 8 feet

The formula for the volume of a cube is given by:

V = l * w * h

In case of a cube, the length, width and height are equal so the volume will be:

V = l^3

Putting l = 8

V = (8)^3\\V = 8*8*8\\V = 512\ ft^3

Hence,

the volume of the cube is: 512 cubic feet

Keywords: Volume, cube

Kristen invests $ 5745 in a bank. The bank 6.5% interest compounded monthly. How long must she leave the money in the bank for i
podryga [215]

Answer:

1. 10.7 years

2. 17.0 years

3. 2nd option

Step-by-step explanation:

Use formula for compounded interest

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

where

A is final value, P is initial value, r is interest rate (as decimal), n is number of periods and t is number of years.

In your case,

1. P=$5745, A=2P=$11490, n=12 (compounded monthly), r=0.065 (6.5%) and t is unknown. Then

11490=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12t},\\ \\2=(1.0054)^{12t},\\ \\12t=\log_{1.0054}2,\\ \\t=\dfrac{1}{12}\log_ {1.0054}2\approx 10.7\ years.

2. P=$5745, A=3P=$17235, n=12 (compounded monthly), r=0.065 (6.5%) and t is unknown. Then


17235=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12t},

3=(1.0054)^{12t},

12t=\log_{1.0054}3,

t=\dfrac{1}{12}\log_{1.0054}3\approx 17.0\ years.

3. <u>1 choice:</u> P=$5745, n=12 (compounded monthly), r=0.065 (6.5%), t=5 years and A is unknown. Then

A=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12\cdot 5},\\ \\A=5745\cdot (1.0054)^{60}\approx \$7936.39.

<u>2 choice:</u> P=$5745, n=4 (compounded monthly), r=0.0675 (6.75%), t=5 years and A is unknown. Then

A=5745\cdot \left(1+\dfrac{0.0675}{4}\right)^{4\cdot 5},\\ \\A=5745\cdot (1.0169)^{20}\approx \$8032.58.

The best will be 2nd option, because $8032.58>$7936.39

What is the sum of the measures of the interior angles of a regular polygon if each exterior angle measures 120?
IrinaVladis [17]
The answer would be 180 because the sum of the exterior angles would equal 360 and 360 divided by 120 equals 3 so that means there are 3 sides. Next you find out how much the interior angle is worth by subtracting it from 180 because they're supplementary you would find that the interior angle is equal to 60 degrees then multiply 60 degrees by how many sides there are (3) which equals 180 degrees.
