3/5 of Alice's stickers is twice as many as Berniece's stickers. Alice has 56 more stickers than Bernice.
(a) Find the ratio of Alice's number of stickers to Bernice's number of stickers.
(b) How many stickers does Bernice have?
Answers
B. 24
Explain:
Call x is alice’s sticker
Y is bernice’s sticker
•3/5 of alice’s stickers is twice berniece.
-> 3/5x =2y
•Alice have 56 more than bernice
-> x=y+56
You want to find number of bernice’s sticker log in the second equation to the first equation:
3/5(y+56)=2y
-> y=24
A cylinder has a height h, and a radius (3h-2)
The area of the base is pi (3h-2)^2
The volume of the clinder is V= pi(3h-2)^2h

Answers
Answer:
[tex]V= 4\pi (9h^2 -12h + 4)[/tex]
Step-by-step explanation:
Given
Shape: Cylinder
[tex]Radius = 3h - 2[/tex]
[tex]Height = h[/tex]
[tex]Base\ Area = \pi (3h - 2)^2[/tex]
Required
Simplify the volume
The volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Substitute values for Base Area and Height
[tex]V= \pi(3h-2)^2*h[/tex]
Expand the bracket
[tex]V= \pi(3h-2)(3h-2)*h[/tex]
Open brackets
[tex]V= \pi (9h^2 -6h - 6h + 4) *h[/tex]
[tex]V= \pi (9h^2 -12h + 4) *h[/tex]

The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $28.00. With the coupon book, the fare is reduced to $1.00. Determine the number of times in a month the bus can be used so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book
Answers
Answer:
56 = 56
Step-by-step explanation:
Given:
Bus fare = $2.00
coupon book = 28.00
bus fare w/ coupon book = $1.00
let x be the number of bus rides.
2.00x = 1.00x + 28.00
2.00x - 1.00x = 28.00
1x = 28.00
x = 28.00
24 bus rides for both to have the same cost.
2.00x = 1.00x + 28
2.00(28) = 1.00(28) + 28
56 = 28 + 28
56 = 56

Find the value of x:

Answers
Answer:
-91x² + 5x³ - 56x -15 = 0
Step-by-step explanation:
x² + 3x³ - 2x + 9 = 24 + 54x + 92x² - 2x³
x² + 3x³ - 2x + 9 - 92x² = 24 + 54x + 92x² - 2x³ - 92x²
-91x² + 3x³ - 2x + 9 + 2x³ = 24 + 54x -2x³ + 2x³
-91x² + 5x³ - 2x + 9 - 54x = 24 + 54x - 54x
-91x² + 5x³ - 56x + 9 - 24 = 24 - 24
-91x² + 5x³ - 56x -15 = 0

The Bluejay Apartments is a new development and is in the process of structuring its lease agreements. The company would like to set the damage deposits high enough that tenants will keep the apartments in good condition. The company is actually more concerned about damage than about tenants not paying their rent.
a) Discuss the tax effects of the following alternatives:
i. $1,000 damage deposit with no rent prepayment�
ii. $500 damage deposit and $500 rent for the final month of the lease
iii. $1,000 rent for the final two months of the lease and no damage deposit
b) Which option do you recommend
Answers
Answer:
The Bluejay Apartments
1. Tax Effects of the following Alternatives:
i. $1,000 damage deposit with no rent prepayment
No tax will be paid by The Bluejay Apartments until the deposit will no longer be refunded.
ii. $500 damage deposit and $500 rent for the final month of the lease
Tax will be paid on the rental income of $500 and on the $500 if it will no longer be refunded. If it is taken as part of the rent income for a month, then tax will be paid on a total income of $1,000.
iii. $1,000 rent for the final two months of the lease and no damage deposit
Tax will be paid on the rent income of $1,000.
b) From a tax point of view, option i is recommended.
Step-by-step explanation:
According to the IRS, a security or damage deposit is not taxable when it is received by the landlord. It becomes taxable income when the landlord is no longer obligated to return it to the tenant. The reason a damage deposit is not taxed is that it is recorded as an asset and not an expense or income.
