4 pounds of salt are needed for 18 pounds.

Explanation:

2 pounds > 9 gallons
pounds > 18 gallons

9 times by 2 equals 18.
2 timed by 2 equals 4.
Everything is getting doubled.

A sphere is inscribed in a cube with a surface area of 216 square centimeters. What is the volume of the sphere? Round your answ

qwelly [4]

Answer: 113.04 cm^3

Step-by-step explanation:

The surface area of a cube is:

S = 6*L^2

then:

216 = 6*L^2

216/6 = L^2

L = √(36) = 6

So the length of the side of this square is L = 6cm

Then the diameter of the sphere is also 6 cm, and the radius is half the diameter, so the radius is 3cm.

Now the volume of a sphere is:

V = (4/3)*pi*r^3 = (4/3)*3.14*3^3 = 113.04 cm^3

Solve for A if Ab = ut<br> Solve for c if Kc = 9 a<br> Solve for D if Bd = Ca

pychu [463]

Answer:

Below in bold.

Step-by-step explanation:

Ab = ut

Divide both sides by b

A = ut/b.

The other 2 are solved in a similar way:

Kc = 9a

c = 9a/K

Bd = Ca

d = Ca/B.

A garden hose is spraying a stream of water at a box on the ground with a force of 2.8 pounds. The water stream makes an angle o

Lorico [155]

Answer:

The horizontal component of force is 1.99 pounds.

Step-by-step explanation:

We are given the following in the question:

Force = 2.8 Newtons.

The attached image shows the arrangement.

Angle made by the water stream with the ground

$\theta = 30^\circ$

The horizontal component is given by:

$|F|\cos \theta\\=2.3\cos(30)\\\\=2.3 \times \dfrac{\sqrt3}{2}\\\\=1.99$

Thus, the horizontal component of force is 1.99 pounds.
