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.
EXPLANATION
Given the equation:
1/5m = 4-3/10m (Adding +3/10 to both sides)
1/5m +3/10m = 4 (Adding 1/5 + 3/10)
1/2m = 4 (Isolating m)
m = 2*4 (Multiplying)
m=8
ANSWER: m=8
Answer:
A = -12, B = 9 and C = .2
Step-by-step explanation:
So it just looks like we need to use algebra to move everything around to get it in the form Ax + By = C
So, let's start with 9y = 12x + 0.2. From standard form we have all terms wth variables on one side, so let's do that. the right sie has both a variable term and non variable term, so let's get rid of the variable term. The variable term is 12x, so to get rid of it you subtract 12x from both sides.
9y = 12x + 0.2
9y - 12x = 0.2
To make it exactly in standard form just rarrnge.
-12x + 9y = 0.2
So now we have A = -12, B = 9 and C = .2
calculate area of wall
20 x 1.5 = 30 square meters
now calculate area of 1 block
12 x 18 =216 square centimeters
convert cm to meters 1 cm^2 = 0.0001m^2
so 216 x 0.0001 = 0.0216 sq meter for 1 block
divide area of wall by area of block
30/0.0216 = 1388.88 so 1389 blocks are required.
Did you ever answer it??? I am stuck on this one and I don't know how to figure it out so I can get the answer myself.
