Charlotte invested $33,000 in an account paying an interest rate of 7 3/4% compounded continuously. Alyssa invested $33,000 in an account
paying an interest rate of 7 1/4% compounded daily. After 19 years, how
much more money would Charlotte have in her account than Alyssa, to
the nearest dollar?

Answers

Answer 1

The amount of money more in the account of Charlotte after 19 years than the money in account of Alyssa is, $13035.13

How to calculate the compound interest?

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{n\times100}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Charlotte invested $33,000 in an account paying an interest rate of 7 3/4% compounded continuously for 19 years. The rate of interest is,

[tex]r=7\dfrac{3}{4}\\r=\dfrac{31}{4}\\r=7.75[/tex]

Thus, the final amount in his account after 19 years is,

[tex]A=33000\times\left(1+\dfrac{7.75}{360\times100}\right)^{360(19)}\\A=143861.22[/tex]

Alyssa invested $33,000 in an account paying an interest rate of 7 1/4% compounded daily. The rate of interest is,

[tex]r=7\dfrac{1}{4}\\r=\dfrac{29}{4}\\r=7.25[/tex]

Thus, the final amount in her account after 19 years is,

[tex]A=33000\times\left(1+\dfrac{7.75}{360\times100}\right)^{360(19)}\\A=130826.09[/tex]

The more money would Charlotte have in her account than Alyssa is,

[tex]D=143861.22-130826.09\\D=13035.13[/tex]

Thus, the amount of money more in the account of Charlotte after 19 years than the money in account of Alyssa is, $13035.13

this is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.

we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.

since the sum of all angles is 180°, the equation will be 55°+55°+x=180

combine like terms (55+55), which equals to 110.

If the area of the rectangular base of Julian's tank is approximately 300 square inches, what is the approximate area of the rectangular base of his friend's tank?

302.5 square inches
468.75 square inches
750 square inches
375 square inches

Answers

The area of the rectangular base of his friend's tank is 468.75 square inches. So, Option D is correct.

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

One of Julian's friends also has a rectangular aquarium.

The dimensions of his friend's tank are each exactly 1 1/4 times the dimensions of Julian's tank.

Let x be the length of Julian's tank.

Let y be the width of Julian's tank.

So, the Area of Julian's tank = length × Width

                                               = xy

Since we are given

300 = xy

Now we are given that the dimensions of his friend's tank are each exactly times the dimensions of Julian's tank.

So, the length of his friend's tank = 5/4 x

So, the width of his friend's tank = 5/4 y

So, Area of his friend's tank = ( 5/4 x) (5/4 y)

                                           = 25 / 16 xy

                                           = 25 / 16 (300)

                                           = 468.75

                         

Hence the area of the rectangular base of his friend's tank is 468.75 square inches.

So, Option D is correct.

Carolina, with the intention of investing money in real estate, acquired a plot of land for R$ 350,000.00. Over four years, the asset underwent changes in its commercial value, as follows variations:

First year: 12% appreciation
Second year: 10% appreciation
Third year: 8% devaluation
Fourth year: 6% appreciation

Having this information as a reference, it is correct to say that at the end of the analyzed period this plot of land
will have the value of:

(A) BRL 329,000.00.
(B) BRL 372,901.76.
(C) BRL 420,000.00.
(D) BRL 420,506.24.
(E) BRL 437,754.24.

Answers

At the end of the analyzed period this plot of land will have the value as given by: Option D: 420,506.24

What is appreciation and deprecation?

Deprecation, also called devaluation, is the decrement in price of an asset. Appreciation is opposite of deprecation. This indicates increment in the price of the considered thing.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

It is given that:

Initial price of the plot of land = $350,000First year: 12% appreciationSecond year: 10% appreciationThird year: 8% devaluationFourth year: 6% appreciation

Now, consider appreciation of an amount A by P%.

Then, we have:

Increased price = Initial price + P% of initial price

Increased price = [tex]A + \dfrac{A}{100} \times P = A \times \left(1 + \dfrac{P}{100} \right)[/tex]

Similarly, depreciated price by P% of an amount A is:

Decreased price = [tex]A - \dfrac{A}{100} \times P = A \times \left(1 - \dfrac{P}{100} \right)[/tex]

We've got: A = 350,000

After 1st year, which had 12% appreciation, we get:

[tex]A_1 =A(1 + 12/100) = A(1.12)\\[/tex]
After 2nd year, 10% appreciation we get:

[tex]A_2 =A_1(1 + 10/100) = A_1(1.1) = A(1.12)(1.1)\\[/tex]

After 3rd year, which had 8% devaluation effect on the price, we get:

[tex]A_3 = A_2(1 - 8/100) = A_2(1-0.08) = A_2(0.92) = A(1.12)(1.1)(0.92)[/tex]

After 4th year,  which had 6% appreciation effect on the price, we get:[tex]A_4 = A_3(1 + 6/100) = A_4(1+0.06) = A_3(1.06) = A(1.12)(1.1)(0.92)(1.06)[/tex]

Thus, the final effect on A is:

[tex]A \rightarrow A(1.12)(1.1)(0.92)(1.06) = A(1.2014464)\\\$350,000 \rightarrow 350000(1.2014464) = 420506.24\: \rm dollars[/tex]

Please help me. please

Answers

Step-by-step explanation:

a)

the total length of the outer or also only the inner perimeter ?

I assume the second case. but it is not difficult to change it to the outer perimeter case (per the information of b).

the total length consists of a straight side and 2 radius (left and right) of the end circles.

a radius is half the diameter, so 2×radius = 1 diameter.

so,

400 = length + 49

length = 400 - 49 = 351 m

the length of the straight sides is 351 m.

b)

the difference in length between both perimeters bases only on the difference in length of the circumference of the end circles. the lengths of the straight sides remain the same, not matter if outer or inner perimeter.

the circumference of 2 half circles is the circumference of 1 whole circle.

the circumference of a circle is

2×pi×r = pi×diameter

in our case for the inner perimeter

pi×49 = 153.93804... m

for the outer perimeter the radius and therefore the diameter changes : we have to add 6×1.5 m = 9 m on both sides of the circle

so, the radius of the outer circles is 9 m longer and the diameter 9×2 = 18 m longer : 49 + 18 = 67 m

so, we get for the outer circle perimeter

pi×67 = 210.4867078... m

therefore, the difference in the length of outer and inner perimeter is

210.4867078... - 153.93804... = 56.54866776... m
