Answer:
The answer to your question is ratio = 9
Step-by-step explanation:
Data
Circle 1 radius = 5''
Circle 2 radius = 15''
Process
1.- Calculate the area of circle 1
Area = πr²
Area = π(5)²
Area = 25π
2.- Calculate the area of circle 2
Area = πr²
Area = π(15)²
Area = 225π
3.- Calculate the ratio of the areas
ratio = 225π / 25π
= 9
Answer: A
Step-by-step explanation:
If 40% of the price is profit, then our answer will be 40% of $65.
40% x $65 = 0.4 x $65 = $26
The store profits $26
(x - 2)(x - 5)(x - k) >= 0
Let's set each term equal to 0
x - 2= 0
Add 2 to both sides
x = 2.
x - 5 = 0
Add 5 to both sides
x = 5
x - k = 0
Add k to both sides
x = k
Since x = 2 and 5, k = 2, 5
Let's plug our numbers into the inequality.
(2 - 2)(2 - 5)(2 - 2) >= 0
(0)(-3)(0) >= 0
0>=0
(5 - 2)(5 - 5)(5 - 5) >= 0
(3)(0)(0) >= 0
0 >= 0
This proves that 2 and 5 are equal to k
