Answer:

  3 in

Step-by-step explanation:

The volume of the large sphere is ...

  V = (4/3)πr³ = 288π . . . cubic inches

The volume of the smaller sphere is ...

  288π -252π = 36π . . . cubic inches

The ratio of volumes of the smaller sphere to the larger is the cube of the ratio of radii. The radius of the smaller sphere will be ...

  (6 in)∛(36π/(288π)) = (6 in)∛(1/8) = 3 in . . . . small sphere radius

The Hudson high school wrestling team just won the state tournament and have been awarded a triangular pennant to hang on the wa
Eduardwww [97]

Answer:

3 feet.

Step-by-step explanation:

  • Base of the  triangular pennant = 1.5 feet long.
  • Area of the triangular pennant = 2.25 Square feet.

Now, we know that:

Area of a Triangle=\frac{1}{2}$ X Base X Height

Substituting the given values, we have:

2.25=\dfrac{1}{2}$ X 1.5 X Height\\\\2.25=$\dfrac{1.5}{2}$  X Height\\\\Cross multiply\\\\2.25*2=1.5  X Height\\\\Divide both sides by 1.5 to solve for the height\\\\\dfrac{2.25*2}{1.5}=\dfrac{1.5  X Height}{1.5}\\\\$Height of the Triangle =3 feet

Therefore, the height of the pennant is 3 feet.

Bryan and Jadyn had barbeque potato chips and soda at a football party. Bryan ate 3 oz of chips and drank 2 cups of soda for a t
Diano4ka-milaya [45]

Answer:

200 mg sodium is in 1 oz of chips and 50 mg sodium is in 1 cup of soda.

Step-by-step explanation:

Let x mg sodium is in 1 oz of chips and and y mg is in 1 cup of soda.

∵ Bryan ate 3 oz of chips and drank 2 cups of soda for a total of 700 mg of sodium.

i.e. 3x + 2y = 700 --------(1),

Jadyn ate 1 oz of chips and drank 3 cups of soda for a total of 350 mg of sodium.

i.e. x + 3y = 350 ---------(2),

Equation (1) - 3 × equation (2),

We get,

2y - 9y = 700 - 1050

-7y = -350

\implies y = \frac{-350}{-7}= 50

From equation (1),

3x + 2(50) = 700

3x + 100 = 700

3x = 700 - 100

3x = 600

\implies x = \frac{600}{3}=200

Hence, 200 mg sodium is in 1 oz of chips and 50 mg sodium is in 1 cup of soda.
