Step-by-step explanation:
Given that,
The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.
The tank is filled to 80% capacity with water.
We need to find the water needed for this tank.
The volume of cuboid is given by :

As it is filled to 80% capacity, so,

So,
of water is needed for this tank.
Answer: 24
Step-by-step explanation:
Let the number of defeats be represented by x.
Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:
= x + 4
We then add the number of victories and losses together and equate them to 44. This will be:
x + x + 4 = 44
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 40/2
x = 20
Therefore number of victories will be:
= x + 4
= 20 + 4
= 24
Answer: Choice A
Set the radicand (stuff under the radical) greater than or equal to 0. Solve x+11 >= 0 for x to get x >= -11

Answer:
$562,500 per hour
Step-by-step explanation:
The cost will be a minimum where C'(x) = 0.
C'(x) = 0.56x -0.7 = 0
x = 0.7/0.56 = 1.25
The cost at that production point is ...
C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625
The minimum production cost is $562,500 per hour for production of 1250 items per hour.
_____
<em>Additional comment</em>
This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.
