The diameter of the new rubber ball, to the nearest foot, must be D = 4.0 ft (in the case of the maximum cost).
<h3>
How to find the diameter of the ball?</h3>
Remember that for a sphere of diameter D, the surface area is:
A = 4*pi*(D/2)^2
In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:
$0.02*A = $1
A = $1/$0.02 = 50
So the surface of the ball must be 50 square feet.
Then we solve:
50ft^2 = 4*3.14*(D/2)^2
D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft

The <u><em>correct answer</em></u> is:
1983 B.C.
Explanation:
To subtract this, we can reverse the order and make the answer negative. The reason for this is that we are taking away more than we have, so we will have a negative answer.
4000-2017 = 1983
In terms of time, though, we don't deal with negatives, we deal with A.D. and B.C. The use of A.D. is for dates after the year 1; B.C. is for anything before this. Since our number is "negative," it will be 1983 B.C.
5x - 9 = -30
"Nine less than" means - 9
"Five times a number" means 5*unknown number = 5x
Answer:
A
Step-by-step explanation:
A statementent of the relationship and a function is that the numbers from the x-axis cannot be double number with another number heres an example.
For Example:
1 6
7 4
5 2
Ok for example the number seven can only be with only one of the numbers from the right side but the number from the right side can be with more than one number get it now?
I hope this helps you for your math class.
