To calculate the monthly deposit needed to earn $50,000 per year in interest alone, we can use the present value of an annuity formula:

PV = PMT x ((1 - (1 + r/n)^(-nt)) / (r/n))

Where PV is the present value, PMT is the monthly deposit, r is the annual interest rate (13%), n is the number of times the interest is compounded per year (12), and t is the number of years (30).

We want to solve for PMT, so we can rearrange the formula:

PMT = PV / ((1 - (1 + r/n)^(-nt)) / (r/n))

Since we want to earn $50,000 per year in interest alone, and the principal will be untouched, the present value is $0. So the formula simplifies to:

PMT = ($50,000 / ((1 - (1 + 0.13/12)^(-12*30)) / (0.13/12)))

Using a financial calculator or spreadsheet, we can calculate that the monthly deposit needed is approximately $436.

Therefore, to earn $50,000 per year in interest alone, while leaving the principal untouched, you would need to deposit approximately $436 at the end of each month into an IRA that pays 13% compounded monthly, for a period of 30 years.

The number of toothpicks that the jumbo box hold is 6760.

From the information, there are 250 toothpicks in a regular-size box and jumbo-size box is made by tripling the length, width, and height of the regular box.

Therefore, the number of toothpicks will be illustrated by multiplying the value by the change. This will be:

= 250 × 3 × 3 × 3

= 6750

This was because the dimensions were tripled

(a) Average velocity = -7(5^2-1^2) + 70(5-1) = -90 m/s.

(b) Average velocity = -7(4^2-1^2) + 70(4-1) = -62 m/s.

(c) Average velocity = -7(3^2-1^2) + 70(3-1) = -34 m/s.

(d) Average velocity = -7(1+h)^2 + 70(1+h-1) = -7h^2 + 70h m/s.

(a) Average velocity = -7(5^2-1^2) + 70(5-1) = -7(25-1) + 70(4) = -7*24 + 280 = -168 + 280 = -88 m/s.

(b) Average velocity = -7(4^2-1^2) + 70(4-1) = -7(16-1) + 70(3) = -7*15 + 210 = -105 + 210 = -95 m/s.

(c) Average velocity = -7(3^2-1^2) + 70(3-1) = -7(9-1) + 70(2) = -7*8 + 140 = -56 + 140 = -16 m/s.

(d) Average velocity = -7(1+h)^2 + 70(1+h-1) = -7(1+h)^2 + 70h = -7(1+h)^2 + 70h m/s. The average velocity of an object over a given period of time is calculated by taking the difference between the final and initial positions, and dividing it by the amount of time elapsed. In this exercise, we are given the position of an object along a line as a function of time, s(t) = -7t^2 + 70t. To solve each part, we can plug in the given time intervals into the function, and calculate the difference between the initial and final positions. We then divide this difference by the amount of time elapsed to find the average velocity. For example, in part (a), the average velocity is calculated as -7(5^2-1^2) + 70(5-1) = -90 m/s. In part (b), the average velocity is calculated as -7(4^2-1^2) + 70(4-1) = -62 m/s. In part (c), the average velocity is calculated as -7(3^2-1^2) + 70(3-1) = -34 m/s. Finally, in part (d), the average velocity is calculated as -7(1+h)^2 + 70h m/s

Step-by-step explanation:

ito answer: Combine 130 and x2.C=x230−2x+1530

The choice that is equivalent to the given product when x>0 is (C) x/2.

The result of multiplying two terms with two different signs will be negative, while the product of two factors with the same signs will be positive.

(xa * xb) = x(m + n) if x is a variable and a and b are positive integers.

To simplify the given product, we can combine the square roots and simplify the coefficients:

\($\begin{aligned} \sqrt{\frac{3x}{2}}\times\sqrt{\frac{x}{6}} &= \sqrt{\frac{3x}{2}\cdot\frac{x}{6}} \ &= \sqrt{\frac{3x^2}{12}} \ &= \sqrt{\frac{x^2}{4}} \ &= \frac{x}{2} \end{aligned}\)

Answer:

B. 745 miles

Step-by-step explanation:

Given that

Kim took 3000 miles trip in 4 days

And,

1st day - 850 miles

2nd day - 745 miles

3rd day - 660 miles

We need to find out that how much she travel in the 4th day

So, it is

= 3000 miles - 850 miles - 745 miles - 660 miles

= 745 miles

Hence, the option b is correct

Answer:

The commission rate is 15%

Step-by-step explanation:

commission = commission rate x sales

where the commission rate is expressed as a decimal.

In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:

345 = commission rate x 2300

To solve for the commission rate, we can divide both sides by 2300:

commission rate = 345/2300

Simplifying this expression, we get:

commission rate = 0.15

So, the commission rate is 15%

Answer:

84,206 is exactly 10 less than 84,216, making 84,216 larger.

Step-by-step explanation:

Answer:

Step-by-step explanation:

a. The probability to get a sample average of 33 or more customers if the manager had not offered the discount is  0.0139.

b. Yes, there is only a small chance (less than 5%) of getting 33 or more customers without the discount if you want to know about confident feel that manager's discount strategy has worked.

a. To find the probability of getting a sample average of 33 or more customers without the discount, we need to find the z-score corresponding to this value. We can use the formula:

z = (x - μ) / (σ/√n)

where x is the sample average (33), μ is the population mean (25), σ is the population standard deviation (10), and n is the sample size (5). Plugging in the values, we get:

z = (33 - 25) / (10 / √5) = 2.236

Using a standard normal table, the probability of getting a z-score of 2.236 or higher is 0.0139. So, the probability of getting a sample average of 33 or more customers without the discount is 0.0139.

b. Based on the probability we found in part a, we can conclude that it is very unlikely (less than 1.5%) to get a sample average of 33 or more customers without the discount.

Therefore, we can say that there is only a small chance (less than 5%) of getting 33 or more customers without the discount, and it is likely that the manager's discount strategy has worked. So, the answer is "Yes, there is only a small chance (less than 5%) of getting 33 or more customers without the discount".

The density of the Machu Picchu place is 3586.14 visitor per square miles

He currently has about 18000 visitors daily.

This means for each day his visitors are 18000.

The area of his apartment is 13 km square.

The daily visitor density can be calculated as follows:

Therefore,

number of visitor daily = 18000

area of the place = 13 km square

13 km² = 5.01933 miles²

Hence,

How crowded or density of the place = 18000 / 5.01933

How crowded or density of the place = 3586.13599823

How crowded or density of the place = 3586.14 visitor per square miles

The equation which correctly relates the measure of diameter and radius of a circle is (c) r = d/2.

The Diameter (d) of a circle is defined as the distance across the circle through its center. The radius (r) of a circle is defined as the distance from the center of the circle to any point on the circle.

We know that the radius of the circle is half of diameter, because it extends from the center to the edge of the circle, while the diameter extends all the way across the circle.

So, we can express the relationship between d and r as:

⇒ d = 2r

To solve for r, we can divide both sides by 2:

We get,

⇒ r = d/2

Therefore, The correct equation is Option (c) r = d/2.
