The figure shown below illustrates the problem.
The volume of the empty cone is
V₁ = (1/3) π r²h
The volume of the sphere is
V₂ = (4/3) π r³
Because the melted ice cream completely fills the cone, therefore
V₁ = V₂
(1/3) π r² h = (4/3) π r³
Divide each side by (1/3) π r².
h = 4r
Answer:
The height of the cone is 4 times greater than the radius f the cone.

His equation could be written in quadratic form, which is ax^2+bx=c
we will find number of non-zero elements on each rows
and then we add them
First row:
we can see that non-zero elements are
2 , 3.1 , 22 , 9
so, number of non-zero elements in first row =4
Second row:
we can see that non-zero elements are
21 , 3.2 , 6
so, number of non-zero elements in first row =3
Third row:
we can see that non-zero elements are
1 , 42 , 8
so, number of non-zero elements in first row =3
Fourth row:
we can see that non-zero elements are
40 ,4 , 6,14
so, number of non-zero elements in first row =4
Fifth row:
we can see that non-zero elements are
10 , 20 , 13 , 5 , 6.3
so, number of non-zero elements in first row =5
now, we can add them
so,
total number of non-zero elements = 4 +3+3+4+5
so,
total number of non-zero elements is 19...........Answer
Answer:
-22
Step-by-step explanation:
6j-5k=11
5j-6k=22
-----------------
5(6j-5k)=5(11)
-6(5j-6k)=-6(22)
-----------------------
30j-25k=55
-30j+36k=-132
-----------------------
11k=-77
k=-77/11
k=-7
6j-5(-7)=11
6j+35=11
6j=11-35
6j=-24
j=-24/6
j=-4
------------------
2j+2k=2(-4)+2(-7)=-8-14=-22
