Answer:
1/2 (150 -2x)
Step-by-step explanation:
You know queen parallela has 150 meters to build her pen. That means that the perimeter of the pen must be 150 (meters), therefore if x is the width and L is the lenght, we have
2*x + 2*L = 150
We want the value of L in terms of x, so we will send 2*x to the other side of the equation and we have
2*L = 150 - 2*x
Therefore
L = (150-2*x)*1/2
The correct answer is 1/2 (150 -2x)
I hope this helped you!
Answer:
B
Step-by-step explanation:
To find the volume of the box you will use the volume of the sphere formula to find the radius of the circular region of the sphere. You wil then double the radius to find the diameter.
V = 4/3 x pi x r^3
972 x pi= 4/3 x pi x r^3
729 = r^3
The cubic root of 729 is 9 because 9 x 9 x 9 = 729.
The radius is 9 inches, and the diameter is 18 inches.
The volume of the box is 18 in x 18 in x 18 in or 5832 in.³.
