Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>

Answer:
563.5 cm³
Step-by-step explanation:
Use the formula for the volume of a cone:
V = (1/3)πr²h
Recognize that the radius is half the diameter:
r = (11.9 cm)/2 = 5.95 cm
V = (1/3)π(5.95 cm)²(15.2 cm) ≈ 563.516 cm³
The volume of the cone is about 563.5 cm³.
_____
<em>Additional comment</em>
If you use 3.14 for the value of π, then the result will be 563.2 cm³.
Answer:
B(-7, -3) C(3, -3) D(3, -1) E(-7, -1)
Step-by-step explanation:
*I am just labeling the points*
B(-7, 5) C(3, 5) D(3, 7) E(-7, 7)
If we were to translate the points 8 units down, we would only need to subtract the y-intercept for every point by 8. (Except don’t include any tenth places)
B(-7, -3) C(3, -3) D(3, -1) E(-7, -1)
