Answer:

Step-by-step explanation: the area of the circle is A=r%5E2%2Api

A=x%5E2%2Api

and if x is the diameter of the small circle,then r=x%2F2 and the area of the smaller circle is

A=%28x%2F2%29%5E2%2Api->A=%28x%5E2%2F4%29%2Api

Write a polynomial that represents the area of the square.
Tema [17]

Answer:

The answer to your question is Area = 49n² - 70n + 25    

Step-by-step explanation:

Data

Length of the side = 7n - 5

Formula

Area of a square = side x side

Process

1.- Substitute values

Area = (7n - 5)(7n - 5)

2.- Expand

Area = 49n² - 35n - 35n + 25

3.- Simplify

Area = 49n² - 70n + 25    

4.- The polynomial is 49n² - 70n + 25

A number cube is rolled. What is the probability of rolling a 2,3, or 5?
Liula [17]
Well if the number cube goes up to 6 like most number cubes, then the probability would be 3/6 because there are 3 numbers that you want to roll (2, 3, and 5) out of 6 total numbers (1-6). Then 3/6 can be further simplified to 1/2. So the answer should be 1/2.

First. we have 150% so let's divide 150%/100=1.5

Second. you will multiply 1.5*39= 26%

39/150=0.26
0.26/100=26

39 is 26% of 150
