Answer:
Maximum volume error = ±540 cm³
Relative error = 0.02
Percentage error = 2%
Step-by-step explanation:
Relative error : The ratio of volume error to the total volume.
Percentage error: The product of relative error and 100.
The volume of a cube is = 
v =x³
Differentiate with respect to x


Here are x = 30 cm and dx= ±0.2 cm
∴ dv = 3×(30 cm)² (±0.2 cm)
=±540 cm³
The volume of the cube = 30³ cm ³ = 27,000 cm³
Then the relative error


= 0.02.
The percentage error
= (0.02×100)
=2%
For this case what we can do to represent this problem is the following rule of three:
25 feet ---> 10 inches
450 feet ---> x
Clearing the value of x we have:
x = (450/25) * (10)
x = 180 inches.
Now, let's convert this value to feet:
x = 180 * (1/12) = 15 feet
Answer:
Ella's model is 15 feet tall
Answer:
The answer should be B. 86.7
The shape of the window is a trapezoid, and the area of the window is 110.88 square feet
<h3>How to determine the area of the window?</h3>
The given parameters are:
- Long base = 15.2 feet
- Short base = 11.2 feet
- Perpendicular height = 8.4 feet
The shape of the window is a trapezoid.
So, the area is:
Area = 0.5 * (Long + Short) * Height
This gives
Area = 0.5 * (15.2 + 11.2) * 8.4
Evaluate
Area = 110.88
Hence, the area of the window is 110.88 square feet
