Complete Question
Angela has constructed a wedge-shaped pillow for her TV watching needs. It contains 0.35 m³ of fluffy material. The pillow's base area measures 0.5m², and its height stands at 1m.
What is the length of the pillow?
Provide an exact answer (no rounding).
Answer:
1.4m
Step-by-step explanation:
A wedge can be defined as a Triangular prism. Thus,
The volume formula for a wedge (Triangular prism) is given by: 1/2 × B × H × L
b = 0.5m
h = 1 m
l =??
Volume of the wedge = 0.35 m³
0.35 = 1/2 × 0.5 × 1 × L
0.35 = 0.25 × L
Solving for L, we get: L = 0.35/0.25
L = 1.4m
Answer:
Step-by-step explanation:
If you compare numbers based on the hundreds digit, the digits to the left (thousands and ten-thousands) remain the same, while the hundreds digit differs.
This applies for any five-digit numbers structured like:
(3)(5)(not 7)(any digit)(any digit).
Digits to the right of the decimal point, as well as those in the tens and ones places, don't impact this comparison.

Step 
Calculate the volume of a cone
We are aware that
the volume of a cone equals

In this example

Use the Pythagorean Theorem to determine the height h


Step 
Calculate the empty volume inside the cylinder

Thus
the final result is
the empty volume inside the cylinder is 
Answer: y = 2/5 --> y = 0.4
Step-by-step explanation:
The equation 5y = 2 represents a horizontal line at y = 2/5.
This means that the y-coordinate holds the value of 2/5 = 0.4 for any x-coordinate.
