Well set it up first. You get: 8.2-(-3.5) so what you do is that you first subtract 8.2-3.5=4.7. Then you want to find out weather it is negative or positive. First point out which one is bigger in this case 8.2 is bigger and a positive so your answer would be positive. Answer: +8.2 or 8.2
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:
Looking at this, slope seems to be 2 for the graph
So, looking at your options, -4 is less than 2, therefore, the answer is
D, with slope -4
One Half of a number +four =(is) three -(less) than quotien of five and a number :
