Answer:
Between -12 and -13, decimal estimate: -12.2
Step-by-step explanation:
First let's disregard the negative sign, and focus on . The smallest square below it is , or 144. The greatest square right above it is , or 169.
Now we know that is somewhere between 12 and 13. Likewise is between -12 and -13. If 12.5 is the square root of 150, it is too high, so we reduce it to 12.2 to 12.3.
Then we can just negate our answer, since we are looking for , to get about -12.2.

The width of the aquarium is 0.1625 ft.
Step-by-step explanation:
Given,
The length (l) of the aquarium = 2 ft
Height (h) = 1.5 ft
The capacity of water it holds = 3.75 gallons
That means the volume (V) = 3.75 gallon
To find the width(b) of the aquarium.
Formula
- The volume of a cuboid with l as length, b as width and h as height = lbh
So,
V = 3.75×0.13 cube ft
According to the problem,
2×1.5×b = 3.75×0.13
or, b = (3.75×0.13)÷(2×1.5)
or, b = 0.1625 ft
Hence,
The width of the aquarium is 0.1625 ft.
Answer:
32/25
Step-by-step explanation:
Any finite-length, or repeating, decimal number is a rational number. Perhaps you want the number expressed as the ratio of two integers.
__
You can start by recognizing that the value of the number is one hundred twenty-eight hundredths, or 128/100.
This improper fraction can be reduced by removing a factor of 4 from numerator and denominator:
128/100 = 32/25
