Answer:
Orange Circle is approximately 31.4
Blue Circle is approximately 62.8
Step-by-step explanation:
To find the circumfrence of a circle you have to use the equation C=2(pi)r. To find the circumfrence of the orange circle, you first multiply the radius (5) by 2, then by pi which gets you 31.4. You do the same for the blue circle except you add the radius from the blue circle and the orange circle to get 10 times 2 times pi.

Answer:
a. 13 years
b. 27950 students
Step-by-step explanation:
Let x be the number of years since the initial year 2005. In 2005, , in 2006, , and so on.
For college "A" the number of students is given by the function:
For college "B" the number of students is given by the function:
Matching these expressions you have the value of x for which the two colleges have the same number of students.
Then, the two colleges will have the same number of students 13 years later, that is, in 2018.
The number of students that each colleges will have in 2018 will be students.
Answer:
The probability that the next customer will pay with credit card is approximately 0.33
Step-by-step explanation:
The given parameters are;
The number of customers that paid cash = 80 customers
The number of customers that used a debit card = 7 customers
The number of customers that used a credit card = 42 customers
The total number of different payments made = 80 + 7 + 42 = 129 payment
Probability = The number of desired outcome/(The number of possible outcome)
The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)
∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.
