2) Mr. Jenkins deposited $1,200 into an account. He made no additional
deposits or withdrawals. Jenkins earned 4.0% annual simple interest on
the money in the account. What was the balance in dollars and cents in
Mr. Jenkins's account at the end of 4 years?

Answers

Answer 1

Hello, I Am BrotherEye

Answer:

The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Initial deposit = $ 1,250

Interest rate = 4.25% annual simple = 0.0425

Time of investment = 4 years

2. What was the balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years?

Let's recall the simple interest formula, as follows:

A = P * (1 + rt), where:

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the values we know:

A = P * (1 + rt)

A = 1,250 * (1 + 4 * 0.0425)

A = 1,250 * 1.17

A = 1,462.50

The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50

The Pony Express
Chapter 1
At A Nation's Crisis
The Pony Express was the first rapid transit and the first fost mail line across the continent from the Missouri River to the Pacific Coast. It was a system
by means of which messages were carried swiftly on horseback across the plains and deserts, and over the mountains of the far West It brought the
Adontic coost and the Pacific slope ten days nearer to each other.
It had a brief existence of only sixteen months and was supplanted by the transcontinental telegraph. Yet it was of the greatest importance in
binding the East and West together at a time when overland travel was slow and cumbersome, and when a great national crisis made the rapid
communication of news between these sections an imperative necessity.
The Pony Express marked the highest development in overland travel prior to the coming of the Pacific railroad, which it preceded nine years.
It, in fact, proved the feasibility of a transcontinental road and demonstrated that such a line could be built and operated continuously the year
around-a feat that had always been regarded as impossible.
The operation of the Pony Express was a supreme achievement of physical endurance on the part of man and his ever faithful companion, the
horse. The history of this organization should be a lasting monument to the physical sacrifice of man and beast in an effort to accomplish
something worthwhile. Its history should be an enduring tribute to American courage and American organizing genius.

Profile: John John is a 35 year old, divorced man with one child (who lives with his mom). His take home pay is $4123 per month. He pays $1200 per month in child support to his ex-wife. He owns a 2-storey home and his monthly mortgage payments are $475 every 2 weeks. His car expenses total $145 monthly and his car insurance costs him $113 every month. His house insurance is $47.36 monthly. John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.

1.Use one highlighter to identify all sources of income. Total the income for each month.

2.Use a different highlighter to identify all sources of expense. Total the expenses for each month.

3. Subtract the Total Expenses from the Total Income for each

month. A Surplus is when your Income minus Expenses = a positive number.

A Shortage is when your Income minus Expenses = a negative number. Does he have a surplus or a shortage?

Answers

Answer:

1. Income highlight: $4123 of take home pay. That's it.

Total monthly income: $4123

------------------------------------

2. Expense highlight:

$1200 child support

$475 every 2 weeks

$145 car payment

$113 car insurance

$47.36 house insurance

$55 loan payment

Total monthly expense:  $2510.36

(1200 + 2(475) + 145 + 113 + 47.36 + 55 = $2510.36

---------------------------------------------

3. $4123 - 2510.36 = 1612.64 surplus

--------------------------------------------

The only question remaining is what if they want him paying more on his credit line...it's kind of a variable expense at this point.

John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.

Subtract line 2 from line 1 to find your taxable income

Answers

Answer:

is there a pic?

Step-by-step explanation:

Your taxable income for the year is $42,000.

What is your available pay in an expense estimation?

Your taxable income is the amount on which you are taxed in a tax calculation. Start with your $50,000 annual income as your base for the calculation.

Then, at that point, take away the allowances, which diminish your available pay, from the all-out pay. The deductions in this instance total $8,000 As a result, your taxable income will be $42,000, or $50,000 divided by $8,000.

This indicates that you will pay tax on $42,000, which will determine your tax bracket and the amount you owe. Deductions like contributions and expenses lower taxable income, thereby lowering the yearly tax bill.

Deduct the total income from the deductions to determine the taxable income:

Available pay = Complete pay - Allowances

Available pay = $50,000 - $8,000

Available pay = $42,000.

Your taxable income for the year is $42,000.

Answers

Answer:

a) 58.24 square centimeters

b) 5cm

Step-by-step explanation:

a) Area of a parallelogram

The formula for the Area of a parallelogram = Base × Height

Height : 5.2cm

Base : 11.2cm

Area = 5.2 cm × 11.2cm

= 58.24 square centimeters

b) Volume of a cuboid

The formula for the Volume of a cuboid = Length × Width × Height

7cm = Width

3cm = Length

y = Height

Volume = 105cm³

We are to find y

Hence,

105cm³ = 7cm × 3cm × y

y = 105cm³/7cm × 3cm

y = 5cm

Which three lengths could be the lengths
of the sides of a triangle?
A. 4 cm, 8 cm, 13 cm

B. 13 cm, 11 cm, 23 cm

C. 5 cm, 18 cm, 12 cm

D. 25 cm, 8 cm, 16 cm

Answers

Given:

The three lengths in the options.

To find:

Which three lengths could be the lengths of the sides of a triangle?

Solution:

If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.

In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.

Sum of two smaller sides is:

[tex]4+8=12[/tex]

[tex]4+8<13[/tex]

So, the triangle is not possible.

In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.

Sum of two smaller sides is:

[tex]13+11=24[/tex]

[tex]13+11>23[/tex]

So, the triangle is possible.

In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.

Sum of two smaller sides is:

[tex]5+12=17[/tex]

[tex]5+12<18[/tex]

So, the triangle is not possible.

In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.

Sum of two smaller sides is:

[tex]8+16=24[/tex]

[tex]8+16<25[/tex]

So, the triangle is not possible.

Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

Their is a rectangle that has measurements in inches. If the width is 7/8 of an inch and the height is 2/3 of an inch, what is the AREA of the rectangle?

Answers

Answer:

Area of a rectangle = 7/12 of an inch

Step-by-step explanation

Area of a rectangle = Length × width

In this case, the length is represented by height

Height = 2/3 of an inch

Width = 7/8 of an inch

Area of a rectangle = Length × width

= 2/3 × 7/8

= (2 * 7) / (3 * 8)

= 14 / 24

= 7 / 12

Area of a rectangle = 7/12 of an inch

2 CDs and 9 DVDs cost £69. 2 CDs and 6 DVDs cost £48. i. Form a pair of simultaneous equations to represent these two sentences ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.

Answers

Answer:

Cost of 1 CD = x = £3

Cost of 1 DVD = y = £7

Step-by-step explanation:

Let us represent:

Cost of 1 CD = x

Cost of 1 DVD = y

i. Form a pair of simultaneous equations to represent these two sentences

2 CDs and 9 DVDs cost £69.

2x + 9y = 69.... Equation 1

2 CDs and 6 DVDs cost £48.

2x + 6y = 48..... Equation 2

ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.

Combining both equations together:

2x + 9y = 69.... Equation 1

2x + 6y = 48..... Equation 2

We substract Equation 2 from Equation 1

3y = 21

y = £7

Solving for x using Equation 1

2x + 9y = 69.... Equation 1

2x + 9 × 7 = 69

2x + 63 = 69

Collect like terms

2x = 69 - 63

2x = 6

x = 6/2

x = £3

Therefore,

Cost of 1 CD = x = £3

Cost of 1 DVD = y = £7
