Let x = one of the side lengths of the base.
Then area of the base = x². So volume of the base = x²h.
That gives us x²h = 20. Solving for x, we get x = √(20/h²).
Glass is needed to cover the sides of the aquarium. There are 4 sides and 1 base. Area of a side = hx = h√(20/h²). Area of the base = x² = 20/h. Total area of glass = h√(20/h²) + 20/h. So the cost for glass = 8 * [h√(20/h²) + 20/h] = 8 h√(20/h²) + 160/h.
Metal frame is needed along the edges of the sides. There are 4 edges on the top, 4 edges in the bottom and 4 vertical edges. So the total length of metal frame = 4x + 4x + 4h = 8 √(20/h²) + 4h. Then the cost for metal frame = 7 * [8 √(20/h²) + 4h] = 56 √(20/h²) + 28h.
So the total cost = 8 h√(20/h²) + 160/h + 56 √(20/h²) + 28h
Answer:
Yes, the pre-image and image have the same side length measures
Step-by-step explanation:
we know that
A rigid transformations not change the size or shape of the objects.
Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations.
In this problem
The pre-image and image have the same side length measures
therefore
Is a rigid transformation
Answer:
3 9/10
Step-by-step explanation:
39 = 3(10) + 9
Answer:
Option B
same-side interior angles
Step-by-step explanation:
Given in the question, two non parallel lines a and b.
The area between lines a and b is called the interior of the two lines.
Angles 4 and 5 are same-side interior angles.
Other options are wrong because:
<h3>A)</h3>
The area which not between lines a and b is called the exterior
<h3>C) </h3>
Corresponding angles are on same side of the traversal line.
Example
Angles 1 and 5
<h3>D)</h3>
Alternate interior angles are in interior region but in opposite side of traversal line.
Example
Angles 3 and 5
Answer:
x = -5/2
Step-by-step explanation:
0 = -2x - 5
2x = -5
Divide^
x = -5/2
