Answer:
Volume = 144 ft
Step-by-step explanation:
1. Let's write some things down, so we don't forget them!
Length = 12 ft
Height = 2 ft
Width = 6 ft
2. We can probably assume the sandbox is a rectangle. The formula for the volume of a rectangle is Length x Height x Width. So, 12 x 2 x 6 = 144, therefore that's the volume!
Well you're given the equation and the time.
substitute:
V(t) = 26,000(0.90^t)
V(11) = 26,000(0.90^(11))
V(11) = 8,159.075498
V(11) ≈ 8,159
Answer:
Population after 16 year = 927 people (Approx.)
Step-by-step explanation:
Given:
Decrease rate = 10% per year
Current population = 5,000
Find:
Population after 16 year
Computation:
A = P[1-r]ⁿ
A = 5,000[1-0.1]¹⁶
A = 5,000[0.9]¹⁶
A = 5,000[0.1853]
A = 926.51
Population after 16 year = 927 people (Approx.)
Answer:
um 2y
Step-by-step explanation:
The sum of interior angles of a triangle is always* 180°, so the following triangles are possible:
- 90°, 40°, 50°
- 82°, 38°, 60°
- 59°, 31°, 90°
_____
The following are not possible triangles.
- 65°, 25°, 75° — add to 165° ≠ 180°
- 57°, 70°, 33° — add to 160° ≠ 180°
_____
* in plane Euclidean geometry. There are other topologies such that the sum of angles of a triangle differs from 180°.
