Answer:
$1.95
Step-by-step explanation:
The lateral area is the area of everything but the base. A shortcut formula for this area is Ph. (where P is the perimeter of the base and h is the height of the prism).
So the lateral area is (3+9+9.49)x37 = 795.13 m^2 or 795 m^2
The surface area is the lateral area plus the area of the 2 bases. The base is a triangle. (area = 1/2 bh)
Since there are two identical bases, the total area of the base is just 3x9 = 27
So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
Answer:
6.84 ≤ x ≤ 37.39
Step-by-step explanation:
we have
-----> equation A
we know that
The company wants to keep its profits at or above $225,000,
so
-----> inequality B
Remember that P(x) is in thousands of dollars
Solve the system by graphing
using a graphing tool
The solution is the interval [6.78,39.22]
see the attached figure
therefore
A reasonable constraint for the model is
6.84 ≤ x ≤ 37.39
Answer:
<h2>
V ≈ 160.85 cm³ ≈ 0,161 l</h2>
Step-by-step explanation:
Volume of cylinder: V = π×r² × h
r = 3.2 cm
h = 5 cm
Volume:
V = π×(3.2)²×5 = 51.2π cm³ = 160.8495.... cm³ ≈ 160.85 cm³
