We will use a method of substitution.
y = 5/2 x + 2
2 y = 5 x + 4 ⇒ 2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0 ⇒ x, y ∈ R
Answer: D)
This system has infinitely many solutions.
Answer:
h = 2,67 units of length
Step-by-step explanation:
Volume of a cone is
V(c) = 1/3*π*r²
Where π*r² is area of the base
we know V(c) = 40 cubit units, and area of the base 15 square units, then
V(c) = Area of the base * h (height of the cone )
V(c) = 15 * h
h = V(c) / 15 ⇒ h = 40 / 15 ⇒ h = 2,67 units of length
Answer:
r = 3
Step-by-step explanation:
The formula of a volume of a cone
V= 1/3 pie r^2 H
r - radius
H - height
We have V = 12π in³ and H = 4 in. Substitute:
