Propane is stored in a cylindrical tank with a diameter of 15 inches and a height of 48 inches. Which equation could be used to

determine the radius of a spherical tank with the same volume?

Step-by-step explanation:

remember. the radius is always half the diameter.

volume of a cylinder

pi × r² × height

pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³

volume of a sphere

4/3 × pi × r³

and that volume should be the same as the cylinder. so,

4/3 × pi × r³ = pi×56.25×48

4/3 × r³ = 56.25 × 48

1/3 × r³ = 56.25 × 12

r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025

r =  \sqrt[3]{2025}

which would be 12.65148998... in.

Answer:

<h2>it will take 30 minutes</h2>

Step-by-step explanation:

obtain a formula

<h3>=> M = $0.10($p)+$25</h3>

<u>insert the value of p dollars</u>

<h3>=> M = $0.10(50) + 25</h3>

<u>multiply 50 by 0.10</u>

<h3>=> M = $5 + 25</h3>

<em> </em><u>add 25 + 5</u>

<h3><em><u>=></u></em> M = $30</h3>

<u>So it takes 30 minutes for international minutes</u> <em><u>Thank </u></em><em><u>You</u></em>

Aaron found rhe length of the diagonal of a rectangle to be an irrational number. What could be the lenght of the diagonal
Amanda [17]

Answer:

See below

Step-by-step explanation:

It could be a positive square root l like √10  ( the number not being a perfect square).

He would have obtained this value from the application of the Pythagoras theorem. For example the length and width of the rectangle might have been 3 and 1 foot respectively, so the diagonal would have length  √(3^2 + 1^2) = √10.

He could give an estimate of the length to nearest hundredth using his calculator. This would be 3.16 feet.

At t= 0, a particle starts from rest at x= 0, y = 0, and moves in the xy plane with an acceleration a⃗ = (4.0i^ + 3.0j^)m/s2. As
alexira [117]
Given that: a = acceleration = (4i^ + 3j^) m/s^2

Using the following relations:
a = dv/dt
v = <span>∫ a dt

such that:
</span>v = ∫ (<span>4i^ + 3j^</span>) dt + C
v = (4t + Cx)i^ + (3t + Cy)j^

Therefore:
Vx = 4t + Cx
Vy = 3t + Cy

At t = 0, Cx = Cy = 0

Finally:

Vx = 4t
Vy = 3t
