Answer: second option Let (2a +1) be an odd number. Let (2b +1) be a different odd number. Because the sum of these two numbers, 2(a + b + 1), is a multiple of 2, it is an even number.
Answer:
The area of this park is 130.60 square miles.
Step-by-step explanation:
Given : The scale of a certain map is 
inch = 16 miles. A square park is represented on the map by a square with side length 
inch.
To find : What is the actual area of this park?
Solution :
The scale of a certain map is inch = 16 miles.
Let the side length of inch = x miles.
So, 
The side length of a square is 11.428 miles.
The area of the square is 
.
To nearest hundredth,
The area of this park is 130.60 square miles.
Answer: the radius is 2.61 cm
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 156 cm³
Height = 7.3 cm
Therefore,
156 = 3.14 × r² × 7.3
156 = 22.922r²
r² = 156/22.922 = 6.81
Taking square root of both sides of the equation, it becomes
r = 2.61 cm
First find the product of 1.36 and 15
1.36×15=20.4
5,300.012+20.4= 5,320.412
