DP BOOT

Answers

Answer 1

Answer:

  £46

Step-by-step explanation:

You want to know the cost of luggage in the hold when 2 in the hand and 1 in the hold is £86, and 1 in the hand and 1 in the hold is £66.

Relations

Let 'a' and 'b' represent the costs of a piece of hand luggage and one in the hold, respectively. Then the given relations are ...

  2a +b = 86

  a +b = 66

Solution

Subtracting the first equation from twice the second gives ...

  2(a +b) -(2a +b) = 2(66) -(86)

  b = 46 . . . . . . . simplify

It costs £46 to put an item of luggage in the hold.

3 newspapers every 12 days as a ratio is - 3:12


3:12 / 3 = 1:4

Find the surface area of the cylinder. ROUND YOUR ANSWER TO THE NEAREST TENTH. PLEASE I NEED HELP also if anyone can I need the steps:(

Answers

Answer:

Area = 87.96

Step-by-step explanation:

87.96 square mm, using 3.14 as pi

For surface area of a cylinder:
A = 2(pi)(radius)(height) + 2(pi)(radius squared)


For the first half of that equation:
2(pi)(radius)(height)
2(3.14)(2)(5)
= 62.8

Now the second half of that equation, the area of the circle ends:
2(pi)(radius squared)
= 2(3.14)(2)(2)
= 25.12

Add them up:
62.8 + 25.12 = 87.92

Janice Davidson, single mother of two in her late 20s, manages an in-store boutique at Lacy's Department Store. She earns $60,000 a year before taxes (her gross income) and pays 20% in taxes. Janice's fixed monthly living expenses are $2,400 with another $1,600 in variable/discretionary living expenses. Janice has $13,000 in emergency savings. Janice has an employer-paid disability benefit through the department store where she works. Lacy's provides its employees a long-term disability insurance benefit that pays 60% of an employee's gross salary up to a maximum of $5,000 a month. Would a policy that pays 40% of her gross salary provide enough income to cover Janice's fixed monthly expenses if she became disabled and couldn't work? If yes, how much could she set aside each month after fixed expenses are paid? If no, how much of a shortfall would she have and how could she cover it?​

Answers

Answer:

No, her savings

Step-by-step explanation:

Her monthly income is 5000 (60000/12). She pays $1000 per month (5000x.2) in taxes and has another 2400 in fixed expenses. So her monthly fixed expenses (don’t include 1600 variable) are 3400 (1000+2400). A disability benefit of 40% would pay $2000 per month (5000 x .4). S0 she would be short 1400 per month (2000-3400). She would have to use her $13,000 in savings to make up the difference.

hopefully I interpreted the questions correctly!

a) 40% policy will not cover Janice's fixed monthly expenses.

b) Janice's shortfall is $400.

c) For the shortfall, Janice may resort to emergency funds.

What is a fixed monthly living expense?

A fixed monthly living expense is an expense that does not change from period to period.

Examples of fixed monthly living expenses include:

Mortgage paymentsUtility billsLoan payments.

Data and Calculations:

Annual gross income = $60,000

Annual tax liability = 20% or $12,000 ($60,000 x 20%)

Fixed monthly living expenses = $2,400

Annual fixed living expenses = $28,800 ($2,400 x 12)

Variable discretionary living expenses = $19,200 ($1,600 x 12)

Emergency savings = $13,000

A policy that pays 40% as the disability allowance of gross salary will pay $2,000 ($5,000 x 40%).
