Assuming that the aquarium is rectangular, the formula to work out the volume would be
V = L x H x D
Considering that 1 gallon = 231 inches³
Multiply both by 33.75 to get the total number of inches³ (volume)
231 x 33.75 = 7796.25 inches³
If you also want the depth, read on...
Also, there are 12 inches in one foot
Length = 2 x 12 = 24 inches
Height = 1.5 x 12 = 18 inches
Now we can fill in the information we know
7796.25 = 24 x 18 x D
To work out D, we divide the volume by the values we know
7796.25 / 18 = <span>433.125
433.125 / 24 = </span><span>18.046875 inches
</span>18.046875 / 12 = 1.50390625 feet
To the nearest 2d.p. ≈ 1.5 feet
Answer:
A
Step-by-step explanation:
We can see that the slope is positive, which means that the x-term must be positive.
If you expand and simply both equations into the form y = mx + b, you will find that m is positive for A and negative for B, hence A is the correct answer.
The answer to number 1 is not accurate,the answer to number 2 is accurate, and the answer to number 3 is 102 pounds.
A standard line equation takes the form of y=mx+b
m= the slope so we see that 2 is next to x in your example
A) Slope = 2
Perpendicular lines will have the negative reciprocal of the original equation's slope
2 -> -
B) 
A plus b equals c for my knowledge
