Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded mont

dlinn [17]

Answer:

1)state bank

2)$16.21

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW

Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.Which bank pays higher interest? How much higher?

The Amount in the formula for compound interest is

A= P(1+r)^2

P = principal amount,

r = rate per periods,

t = number of periods,

To know the interest she got from the State bank, we say

P = $ 9000, r = 4.1% = 0.041, t = 2 years,

A= 9000(1+0.041)^2

A= 9000(1.041)^2

= 9767.74

Then interest earned = A - P

= 9767.74 - 9000

= $ 767.74

To know the interest she got from the State bank, we say

P = $ 9000, r = 4.01% = 0.0401, t = 2 years,

A= 9000(1+0.0401)^2

A= 9000(1.0401)^2

= 9751.53

Then interest earned = A - P

= 9767.74 - 9000

= $ 751.53

The difference between the two interest is ($ 767.74 - $ 751.53)

=$16.21

Hence state bank will have $16.21 higher interest

A car wheel is 56 cm in diameter. A. How far does the car go in one revolution of the wheel?

andre [41]

The car moved 175.84 cm in one revolution

The car has moved 17584 cm in 100 revolutions

Solution:

Given that car wheel is 56 cm in diameter

diameter = 56 cm

To find: distance traveled in one revolution of wheel

Usually wheel is of circular shape

one revolution of wheel = circumference of circle

The circumference of circle is given as:

$c = 2 \pi r$

We know that,

diameter = 2(radius)

$d = 2r$

So the circumference becomes:

$c = \pi d$

substitute $\pi$ = 3.14 and d = 56 cm

$c = 3.14 \times 56 = 175.84$

Thus the car moved 175.84 cm in one revolution

B. How far does it go in 100 revolutions

Distance covered in 100 revolutions = 100 x Distance covered in 1 revolution

$\rightarrow 100 \times 175.84 = 17584$

Thus the car has moved 17584 cm in 100 revolutions

The volume of a prism is 8000 mm3. What is the volume of this prism, measured in cm3?

Tema [17]

1meter=1000milimeter
1meter=100centimeter
1000milimeter=100centimeter
1cm=10mm
1cm^3=1000mm^3
8000mm^3 * 1cm^3/(1000mm^3) = 8 cm^3
hopes this gains.
