To add fractions together, you must convert the smaller fraction (
) to a denominator that matches the other fractions denominator.
In this case, 1/2 would become 4/8
We can add 4/8 to 7/8 to get 11/8
Then we can add the 1 to it, which acts as 8.
Which gives us 19/8
Or 2 3/8
5x + 4x + 1
= 9x + 1

Answer:
It helps because you now know the y-intercept and the slope.
Step-by-step explanation:
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
