Answer:
The volume is 3825 cubic units
Step-by-step explanation:
To find the volume of the fish tank multiply out the dimensions.
We were given the dimensions as:

Change the numbers to improper fractions

We cancel out to get


 
        
             
        
        
        
Answer:
   4/5 ft
Step-by-step explanation:
Assuming both boxes need to fit completely on the shelf, Ebony should make it as wide as the largest of the boxes.
In decimal, 4/5 = 0.80 and 3/4 = 0.75, so 4/5 > 3/4. 
The shelf should be 4/5 ft wide.
 
        
             
        
        
        
Answer: Choice C
7 divided by cosec 50 degrees
=====================================
Explanation:
Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)
-----------------
Let the horizontal leg be x
This leg is opposite the angle 50 degrees. The hypotenuse is 7
Opposite = x
Hypotenuse = 7
We'll either use the sine rule or the cosecant (csc) rule
sine = opposite/hypotenuse
cosecant = hypotenuse/opposite
Since "sine" is nowhere to be found in the answer choices, we'll use the cosecant rule
-----------
cosecant = hypotenuse/opposite
csc(angle) = hypotenuse/opposite
csc(50) = 7/x
x*csc(50) = 7
x = 7/csc(50)
This is why the answer is choice C

Divide the number by 1,000,000 (1 million).
Micrometer is a millionth of a meter
11,562/1,000,000 = 0.011562
