We would use the sine function because we have an angle the hypotenuse, and the unknown opposite side.

sin(x)=opposite/hypotenuse
sin(60)=x/30
√3/2=x/30 (cross multiply)
30*√3/2=x (divide numerators and denominators by 2)
x=15√3 ft. 
So the correct answer is A

Hope this helps

An aquarium holds 3D 3.75 gallons of water it has a length of 2 feet and a height of 1.5 ft what is the volume of the aquarium w
just olya [345]

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
  • 1 gallon = 0.13 cube ft

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.

Round 8.95 to the nearest tenth.did the ones place change? explain
Gekata [30.6K]
8.95 to the nearest tenth.

The tenth digit is the first after the decimal point to the right. And that is 9.
Looking at the next digit after it is 5, and it is up to 5 so we increase the 9 to 10.

And of course the 10 would cause an increase to the 8 for it to become 9.

≈ 9.0  to the nearest tenth.
