Your friend tells you that if you let him keep 50 of your Pokemon cards for a month, he will give you 1 card extra when he retur

ns your cards. What is the annual rate of interest he is willing to pay for the borrowed cards? Note: Even though he only keeps your cards for a month, we can still calculate an annual interest rate

Answer:

the answer depends on which type of interest we use:

  • simple interest rate = 24%
  • compound interest rate = 26.82%

Step-by-step explanation:

the interest rate paid for holding the cards one month 1/50 or 2%.

to convert 2% monthly interest rate to a simple annual rate:

monthly rate x 12 months = 2% x 12 = 24%

now to convert 2% monthly interest rate to an annual rate (using compound interest):

  • = (1 + r)ⁿ - 1
  • = (1 + 0.02)¹² - 1 = 1.2682 - 1 = 0.2682 or 26.82%

in compound interest, earned interest earns even more interest by itself besides the interest earned by the principal.

The value of y in the triangle is 7.5

<h3>How to calculate the value of y?</h3>

The given parameter is the triangle

On the triangle, we have the following equivalent ratio

y : 8 = y + 15 : 20

Express as fraction

y/8 = y + 15/20

Cross multiply

20y = 8y + 90

Collect the like terms

20y - 8y = 90

Evaluate

12y = 90

Divide by 12

y = 7.5

Hence, the value of y in the triangle is 7.5

Answer:

it is C 10

Step-by-step explanation:

 If the positions are distinct, as in executive offices, then P(9, 5). 

P(9, 5) = 9!/(9 - 5)! = 15120 

If the positions are equivalent, such as seats in a legislative body, then C(9, 5). 

C(9, 5) = 9!/[(9 - 5)!(5!)] = 126

Assuming the five positions are unique in their duties and responsibilities (i.e. order matters): position 1 has 9 candidates to choose from, position 2 has 8, position 3 has 7, and so on. Otherwise, if you're talking about 5 distinct but duplicate positions - meaning their responsibilities are the same but 5 people are required to carry them out - you need to divide the previous total number of possibilities by the number of ways those possibilities could have been reordered.
