A storage box without a top is 18 inches long , 15 inches wide ,and 10 inches high , The outside of the box is painted yellow .
1 answer:
Answer:
The total area that is painted yellow is
Step-by-step explanation:
we know that
The area of the outside of the box is equal to the surface area of the box minus the area of the top
The area of the outside is
where
B is the area of the base
P is the perimeter of the base
H is the height of the box
<em>Find the area of the base B</em>
<em>Find the perimeter of the base P</em>
we have
substitute the values

Answer:
Step-by-step explanation:
This is a horizontally stretched ellipse. That means that the horizontal line which is represented by the x-axis is the longer one. The equation for this type of ellipse is
In an ellipse, the a value is ALWAYS bigger than the b value, and since the x-axis represents the longer axis, the a goes under the x-squared term.
To solve for the h, the k, the a, and the b, we simply have to do some counting. The center of the ellipse, the (h, k) our of equation, is sitting at (4, 6). Put them where they belong in the equation. The a axis (the horizontal one) is 8 units long, and the b axis (the vertical one) is 4 units long. Square both of them and put them where they belong in the equation:
There you go!
It must be true that a implies c, because of the transitive property.
If a is true, then b is true as well. But every time b is true, c is true as well.
So, "jumping" over b, we have that if a is true, c is true as well.
Think of this example:
- a: I live in Rome
- b: I live in Italy
- c: I live in Europe
It is true that , because Rome is inside Italy, and similarly
, because Italy is a European state.
So, if I live in Rome, I must live in Europe as well.
