After 18 years, how much more money would Santiago have in his account than Ella, to the nearest dollar?

Answers

Answer 1

Answer:331

Step-by-step explanation:

7360.3097-7029.415≈330.8947

Answer 2

Santiago could have $81 more than Ella after 18 years.

To calculate the amount of money each person can have after 18 years, we are able to use the formulation for compound interest:

[tex]A = P(1 + r/n)^{(nt)[/tex]

Wherein:

A = the final amountP = the principalr = the interest price n = the number of times the interest is compounded in step with yeart = the number of years

For Ella's investment:

P = $4,800

r = 2.28125% = 0.0228125

n = 4

t = 18

[tex]A = 4800(1 + 0.0228125/4)^{(4*18)[/tex]

A = $8,481.48

For Santiago's investment:

P = $4,800

r = 2.28333% = 0.0228333

n = 365 (compounded daily)

t = 18

A = 4800(1 + 0.0228333/365)^(365*18)

A = $8,562.02

The distinction of their final amounts is:

$8,562.02 - $8,481.48 = $80.54

Therefore, Santiago could have $81 more than Ella after 18 years.

A car was valued at $44,000 in the year 1992. The value depreciated to $15,000 by the year 2006.
A) What was the annual rate of change between 1992 and 2006?
r=---------------Round the rate of decrease to 4 decimal places.
B) What is the correct answer to part A written in percentage form?
r=---------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2009 ?
value = $ -----------------Round to the nearest 50 dollars.

Answers

(A)  the annual rate of change between 1992 and 2006 was 0.0804

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

What is the rate of change?

The rate of change is a mathematical concept that measures how much one quantity changes with respect to a change in another quantity. It is the ratio of the change in the output value of a function to the change in the input value of the function. It describes how fast or slow a variable is changing over time or distance.

A) The initial value is $44,000 and the final value is $15,000. The time elapsed is 2006 - 1992 = 14 years.

Using the formula for an annual rate of change (r):

final value = initial value * [tex](1 - r)^t[/tex]

where t is the number of years and r is the annual rate of change expressed as a decimal.

Substituting the given values, we get:

$15,000 = $44,000 * (1 - r)¹⁴

Solving for r, we get:

r = 0.0804

So, the annual rate of change between 1992 and 2006 was 0.0804 or approximately 0.0804.

B) To express the rate of change in percentage form, we need to multiply by 100 and add a percent sign:

r = 0.0804 * 100% = 8.04%

C) Assuming the car value continues to drop by the same percentage, we can use the same formula as before to find the value in the year 2009. The time elapsed from 2006 to 2009 is 3 years.

Substituting the known values, we get:

value in 2009 = $15,000 * (1 - 0.0804)³

value in 2009 = $11,628.40

Rounding to the nearest $50, we get:

value in 2009 = $11,650

Hence, (A)  the annual rate of change between 1992 and 2006 was 0.0804

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

Dividends Per Share Seacrest Company has 25,000 shares of cumulative preferred 2% stock, $50 par and 50,000 shares of $25 par common stock. The following amounts were distributed as dividends: 20Y1 $37,500 20Y2 20,000 20Y3 75,000 Determine the dividends per share for preferred and common stock for each year. Round all answers to two decimal places. If an answer is zero, enter '0'.

Answers

To determine the dividends per share for preferred and common stock for each year, we need to use the following formulas:

Dividends per share of preferred stock = Total dividends on preferred stock / Number of outstanding shares of preferred stock

Dividends per share of common stock = Total dividends on common stock / Number of outstanding shares of common stock

First, we need to calculate the total dividends on preferred and common stock for each year:

Year 20Y1:
Total dividends on preferred stock = 25,000 shares x $50 par x 2% = $25,000
Total dividends on common stock = $37,500
Year 20Y2:
Total dividends on preferred stock = $25,000 (cumulative preferred stock) + $20,000 x 2% = $25,400
Total dividends on common stock = $20,000
Year 20Y3:
Total dividends on preferred stock = $25,000 (cumulative preferred stock) + $20,000 (cumulative preferred stock) + $30,000 x 2% = $26,600
Total dividends on common stock = $75,000

Using the formulas above, we can calculate the dividends per share for each year:

Year 20Y1:
Dividends per share of preferred stock = $25,000 / 25,000 shares = $1.00
Dividends per share of common stock = $37,500 / 50,000 shares = $0.75

Year 20Y2:
Dividends per share of preferred stock = $25,400 / 25,000 shares = $1.02
Dividends per share of common stock = $20,000 / 50,000 shares = $0.40

Year 20Y3:
Dividends per share of preferred stock = $26,600 / 25,000 shares = $1.06
Dividends per share of common stock = $75,000 / 50,000 shares = $1.50

Therefore, the dividends per share for preferred and common stock for each year are as follows:

Year 20Y1: Preferred stock = $1.00, Common stock = $0.75
Year 20Y2: Preferred stock = $1.02, Common stock = $0.40
Year 20Y3: Preferred stock = $1.06, Common stock = $1.50

A company makes steel rods shaped like cylinders. Each rod has a diameter of 6 centimeters and a height of 20 centimeters. If the company used 30520.8cm3 of steel, how many rods did it make?

Answers

As a result, the company produced number of rods are **56** rods.

What exactly is radius?

A radius is a section of a straight line in geometry that connects a circle's or sphere's center to its edge or surface Its length is divided by the circle's diameter by two.

Each rod has a diameter of 6 centimeters, hence the radius is 3 centimeters. Each rod has a 20-centimeter height.

The following formula can be used to determine a cylinder's volume:

V = πr²h

where V stands for volume, r for radius, which is equal to half of the diameter, and h for height.

Adding these values to the formula yields the following results:

V = π(3)²(20) (20)

V = 180π

The volume of each rod is therefore 180 cubic centimeters.

30520.8 cubic centimeters of steel were used to make how many rods?

To find out,

Determine the point estimate of the population mean and the margin of error for the given confidence interval. Lower bound: 12 Upper bound: 20To determine the point estimate of the population mean, we simply take the average of the lower and upper bounds of the confidence interval: Point estimate = (Lower bound + Upper bound) / 2 = (12 + 20) / 2 = 16 Therefore, the point estimate of the population mean is 16. To calculate the margin of error, we need to determine the distance between the point estimate and either the lower or upper bound of the confidence interval. We can do this by subtracting the point estimate from the upper bound (or vice versa): Margin of error = (Upper bound - Point estimate) / 2 = (20 - 16) / 2 = 2 Therefore, the margin of error for this confidence interval is 2.

A. 2/7


B. 5/14


C. 4/19


D. 3/7

Answers

The correct option is B. 5/14, which is equivalent to approximately 0.357 or 35.7%

The probability of selecting a chocolate ice cream bucket is calculated by dividing the number of chocolate ice cream buckets by the total number of buckets:

P(chocolate) = number of chocolate ice cream buckets / total number of buckets

P(chocolate) = 5 / 14

P(chocolate) = 0.35714285714285715

To simplify the fraction, we can express it as a decimal or a percentage:

P(chocolate) ≈ 0.357 or P(chocolate) ≈ 35.7%

Therefore, the probability of selecting a chocolate ice cream bucket is approximately 0.357 or 35.7%. The probability of selecting a chocolate ice cream bucket can be calculated by dividing the number of chocolate ice cream buckets by the total number of buckets.

Sales of portable MP3 players grew approximately exponentially from $0.07 billion in 2001 to $0.91 billion in 2005. Predict the sales of MP3 players in 2008

Answers

the sales of portable MP3 players in 2008 will be approximately $3.50 billion. To predict the sales of MP3 players in 2008, we need to first understand the exponential growth pattern of sales from 2001 to 2005.

We are given that sales grew approximately exponentially from $0.07 billion in 2001 to $0.91 billion in 2005. This means that the sales data can be modeled by an exponential function of the form:

[tex]S(t) = a * b^t[/tex]

where S(t) is the sales at year t, a is the initial sales value (in 2001), and b is the growth factor per year. We can find the values of a and b by using the given sales data.

When t = 0 (in 2001), S(t) = $0.07 billion. So, we have:

[tex]0.07 = a * b^0\\a = 0.07[/tex]

When t = 4 (in 2005), S(t) = $0.91 billion. So, we have:

[tex]0.91 = 0.07 * b^4b = (0.91/0.07)^(1/4) = 1.770[/tex]

Therefore, the exponential function that models the sales data is:

[tex]S(t) = 0.07 * (1.770)^t[/tex]

To predict the sales of MP3 players in 2008, we need to find the value of S(7) (since 2008 is 7 years after 2001). We have:

[tex]S(7) = 0.07 * (1.770)^7= $3.50 billion[/tex]

Therefore, we can predict that the sales of portable MP3 players in 2008 will be approximately $3.50 billion.

It is important to note that this is a prediction based on the data we have and the model we have used. The actual sales value in 2008 could be different due to various factors such as market changes, competition, and technological advancements.

A soccer team is planning to sell candy bars to spectators at their games. They will buy two-pound bags of candy. The number of candy bars per bag has mean 12 and standard deviation 2. They will sell each candy bar for $1.25. (Assume that all of the candy in a bag will be sold.)
1. What is the expected value and the standard deviation for the amount of money that would be made selling all of the candy in one bag of candy?

Answers

The expected value for the amount of money made selling all of the candy in one bag is $15, and the standard deviation is approximately $24.33.

What exactly is a standard deviation?

The standard deviation is a measurement of how widely apart a set of numbers or statistics are from their mean.

The expected value for the amount of money made selling all of the candy in one bag can be found by;

Expected value = mean number of candy bars per bag x price per candy bar

Expected value = 12 x $1.25 = $15

Formula for the standard deviation of a product of random variables:

[tex]SD (XY) = \sqrt{((SD(X)^2)(E(Y^2)) + (SD(Y)^2)(E(X^2)) + 2(Cov(X,Y))(E(X))(E(Y)))}[/tex]

where X and Y are random variables, SD is the standard deviation, and Cov is the covariance.

X is the number of candy bars in a bag, which has a mean of 12 and a standard deviation of 2. Y is the price per candy bar, which is a constant $1.25. So we have:

E(Y²) = $1.25² = $1.5625

E(X²) = (SD(X)²) + (E(X)²) = 2² + 12² = 148

Cov (X,Y) = 0 (because X and Y are independent)

Using these values, we can calculate the standard deviation for the amount of money made selling all of the candy in one bag:

[tex]SD = sqrt((2^{2} )(148) + (0)(12)(1.25)^{2} + 2(0)(2)(12)(1.25))[/tex]

SD = √(592)

SD ≈ $24.33

Therefore, the expected value for the amount of money made selling all of the candy in one bag is $15, and the standard deviation is approximately $24.33.

Suppose that a cliff diver's height (in feet) after t seconds is given by the model
H(t)=-16t^2+32t+20 find the height after 1.25 seconds pls help me

Answers

The height of the cliff diver after 1.25 seconds is 35 feet.  

Calculating Height :

The concept used is evaluating a function at a given input or value. In this case, we are evaluating the height function H(t) at t = 1.25 to find the height of the cliff diver after 1.25 seconds. The formula for the height function is given as H(t) = -16t^2 + 32t + 20.

Here we have

A cliff diver's height (in feet) after t seconds is given by the model

H(t)=-16t² +32t +20  

Given time t = 1.25 seconds

To find the height after 1.25 seconds, we simply need to evaluate H(1.25) using the given formula:

H(1.25) = -16(1.25)² + 32(1.25) + 20

On Simplifying the expression we get:

H(1.25) = -16(1.5625) + 40 + 20

H(1.25) = -25 + 60

H(1.25) = 35

Therefore,

The height of the cliff diver after 1.25 seconds is 35 feet.

The number a is less than the number b by (1)/(5) of b. By what part of a is b greater than a ?

Answers

Answer:

B is greater than A by 1/4 of A

Step-by-step explanation:

Let's use the information given in the problem to write expressions for the values of a and b:

a = b - (1/5)b = (4/5)b

b is greater than a by the difference:

b - a = b - (4/5)b = (1/5)b

To express this difference as a fraction of a, we divide by a:

(b - a)/a = ((1/5)b)/((4/5)b) = 1/4

Therefore, b is greater than a by 1/4 of a.

A point at (-5,7) is reflected across the x-axis. The new point is then reflected across the y-axis. What ordered pair names the third point?explain.

Answers

Answer:

Step-by-step explanation:

Reflecting a point across the x-axis negates the y-coordinate, so the point (-5, 7) reflected across the x-axis becomes (-5, -7).

Reflecting a point across the y-axis negates the x-coordinate, so the point (-5, -7) reflected across the y-axis becomes (5, -7).

Therefore, the third point is (5, -7).

First, note that to right side of the y-axis, the x-values are positive. To the left of the y-axis, x-values are negative.
Similarly, above the x-axis, y-values are positive, and below the x-axis, y-values are negative.

Starting with (-5,7), this point is located to the left of the y-axis and above the x-axis.

Reflected over the x-axis, the sign of the y-value changes from positive to negative:

7 becomes -7 so the second point is (-5,-7).

Reflect the second point over the y-axis, and the x-value changes from negative to positive:

-5 becomes 5, so the third point is (5,-7)

The third point is (5,-7).

Determine the length of side FE

Answers

the length of EF is 11 units.

How to solve similar triangles?

Since triangles DEF and GHF are both right triangles, we can use the Pythagorean theorem to find the length of EF.

Let's first find the lengths of DE and EF.

DE = DF + FE = 13 + x, where x is the length of FE.

GF = DE - DG = (13 + x) - 4 = 9 + x.

GH = 4.

Now, using the Pythagorean theorem in triangle GHF, we have:

GH² + HF² = GF²

4²+ HF² = (9 + x)²

16 + HF² = 81 + 18x + x²

And in triangle DEF, we have:

DE²+ EF² = DF²

(13 + x)² + EF² = 13²

169 + 26x + x²+ EF² = 169

Simplifying the above equation, we get:

EF²= -26x - x²

Substituting this into the equation we got from the GHF triangle, we have:

16 + HF² = 81 + 18x + x² - EF²

16 + HF² = 81 + 18x + x²+ 26x + x²

HF² = 97 + 44x + 2x²

Now, using the fact that HE + EF = HF, we have:

8 + x = √(97 + 44x + 2x²)

Squaring both sides and simplifying, we get:

4x² + 16x - 225 = 0

Solving this quadratic equation, we get:

x = (-16 ± √(16² - 44(-225)))/(2*4) = (-16 ± 34)/8

Since x has to be positive, we take the positive solution:

x = 3

Therefore, EF = HE + FE = 8 + 3 = 11.

So the length of EF is 11 units.
