Based on a $400 loan amount, rank the following companies from the lowest to highest annual percentage rate (APR)

Answers

Answer:

Step-by-step explanation:

A = 40* (365/5)= 29.2%

B = 50*(365/12) = 15.2%

C= 80*(365/15)=19.46%

D = 100*(365/20)=18.25%

so best is B,  then D , then C then A .  

B,D,C,A   in lowest to highest APR

As per the given data, with a base of $400 for loan amount, the ranking of all the given companies from the lowest to highest annual percentage rate is B,D,C, and A.

What is the annual percentage rate?

Annual borrowing costs, including fees, are stated as a percentage and are known as the annual percentage rate, or APR. The APR is a more comprehensive indicator of how much borrowing money will cost because it includes both interest rates and application fees.

Instead of just a monthly fee or rate, the term annual percentage rate of charge refers to the interest rate for the entire year as applied to a loan, home loan, credit card, and many more. It can also be referred to as a nominal APR or an effective APR. It is a financial fee that is calculated at an annual rate.

Required calculations are as follow:

A = 40 × (365/5)= 29.2%

B = 50 × (365/12) = 15.2%

C= 80 × (365/15)=19.46%

D = 100 × (365/20)=18.25%

Therefore, the ranking of all the companies  with the lowest to highest annual percentage rate are B,D,C, and A.

Dan invests £1500 into his bank account.
He receives 3% per year simple interest.
How much will Dan have after 2 years?
Give your answer to the nearest penny where appropriate.

Answers

Answer:

£1,725.00

Step-by-step explanation:

To calculate simple interest, we use the formula:

a = p(1 + rt)

a is the answer

p is the principle, or the starting amount of money

r is the rate, or the rate of interest (the percent)

and t is the time, or years.

First, 3% as a decimal is 0.03

So we can plug that in as r.

Then just plug the rest of the numbers in.

a = 1500(1 + 0.03 x 2)

Then just solve the equation to get 1,725.00.

Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units. Container B has the same radius as container A. Which statement derives the formula to find the volume of container A?

container A is a right cylinder that has had a right cone subtracted from its base, container B is half of a sphere

π(92)(9) − 1 over 3π(92)(9)
2[π(92)(9) − 1 over 3π(92)(9)]
1 over 3π(92)(9) − π(92)(9)
2[1 over 3π(92)(9) − π(92)(9)]

Answers

Answer:

a. π(92)(9) − 1 over 3π(92)(9)

Step-by-step explanation:

Solution given: For A

height =9units

breadth =9units

for both cylinder and cone

Volume of container A=volume of cylinder -volume of cone

=πr²h-1/3×πr²h=π(9²)9-1/3×(9²)9

so your final answer is A

a. π(92)(9) − 1 over 3π(92)(9)

The volume of the container A and container B will be π(9²)9 – (1/3)π (9²)h. Then the correct option is A.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units.

Then the volume of the container A will be given as

Volume of A = Volume of cylinder – volume of cone

Volume of A = πr²h – (1/3)πr²h

Volume of A = π(9²)9 – (1/3)π (9²)h

Volume of A = (2/3) π(9)³

Container B has the same radius as container A.

Volume of B = (4/6) πr³

Volume of B = (2/3) π(9)³

Then the correct option is A.

According to the above we can establish that based on the given statistics, the average household paid approximately $97.52 per year in federal gasoline taxes.

How to calculate how much average household paid per year in federal gasoline taxes?

To calculate how much the average household paid per year in federal gasoline taxes, we can use the following steps:

Determine the total number of gallons of gasoline consumed by the average household per year:

Total gallons = (Total miles driven) / (Miles per gallon)Total gallons = 11,340 miles / 21.4 miles per gallonTotal gallons = 530 gallons (rounded to the nearest gallon)

Calculate the total amount paid in federal gasoline taxes per year:

Total taxes = (Total gallons) * (Tax rate per gallon)Total taxes = 530 gallons * $0.184 per gallonTotal taxes = $97.52

According to the above we can establish that based on the given statistics, the average household paid approximately $97.52 per year in federal gasoline taxes.

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[0.5,12.5][/tex]

The data values 0 and 13 lie outside the range [0.5,12.5].

Therefore, 0 and 13 are outliers of the given data set.
