The answer to this question is 7/10 because 3 out of 10 marbles are green so the rest is a different color.
Answer:
12 inches
Step-by-step explanation:
Suppose the ice cream scoop has the shape of a sphere of a radius (r) inches.
Thus, the top of the cone will also have a radius (r) inches.
Let consider h to be the height of the cone in inches.
So, the objective is to make the volume of the scoop of the ice cream to be the same as the volume of the cone.
To do that; we need to equate both volumes together and make h the subject of the formula:
The volume of a sphere = 4/3 πr³ and the volume of a cone = 1/3πr²h
4/3 πr³ = 1/3πr²h
Multiply both sides by 3
4πr³ = πr²h
4r = h
h = 4(3)
h = 12 inches
To contain all the ice cream inside the cone, the height of the ice cream cone needs to be 12 inches tall
Answer:
x=4 x=-5
Step-by-step explanation:
x^2+x-20=0
Factor
What 2 numbers multiply to -20 and add to 1
-4*5 =-20 and
-4+5 =1
(x-4) (x+5) =0
Using the zero product property
x-4 =0 x+5=0
x=4 x=-5

Answer:
- y-intercept: y=9
- zeros: x= -3, -1, 1, 3
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. On this graph, that is just below y=10. A reasonable estimate* of the y-intercept is y=9.
__
The zeros are those places on the graph where y=0. The line y=0 is the x-axis, so the zeros are the x-values of the places where the graph crosses the x-axis. Those points are clearly labeled: x = -3, -1, 1, 3.
_____
* Knowing the zeros, you can write a factored-form equation for the graph:
y = (x +3)(x +1)(x -1)(x -3)
You can substitute x=0 in this equation to see what the y-intercept would be:
3×1×-1×-3 = 9
That is, with no scale factor applied to the function, its y-intercept would be 9. This is the same value we estimated above, so it is reasonable to assume that value is correct.
