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.

original=100%
75% off means
100%-75%=25%
remaining is 25%
it was sold for 45
therfor
25%=45
find 100%
just multipl it by 4 since 25 times 4=100
100%=45 times 4=180
originl price=180
answer is A
7. simle interest
I=PRT
P=principal=1000
I=interest=300
T=time=5
R=rate in percent form=?
300=1000*?*5
300=5000?
divide both sides by 5000
0.06=?
