Answer:

A 83 cups

B 16 cups.

Step-by-step explanation:

A) the volume of the cone = 1/3 pi r^2 h

= 1/3 pi 2^2 * 6

= 8pi

Number of cups needed = 2000/3 pi / 8  pi

= 83 cups to the nearest cup.

B)  Volume of this cup is  1/3 pi 4^2 * 8 = 128/3 pi

Number of cups required = 2000/ 3  * 3 / 128

=  15. 6 cups.

Your basketball team scored 4 fewer than twice as many points, x, as the other team. a. Write an expression for the number of po
velikii [3]

Answer:

A) p = 2x - 4  for the expression. B) Your team scored 44 points.

Step-by-step explanation:

Let <u>P</u> represent the points your team made.

Since the question says "Your basketball team scored 4 fewer than twice as many points as the other team." this is how I came up with the expression.

p = 2x - 4 ( our points = 2 times more then the other teams points minus 4.

Using this expression and the given information that the other team made 24 points, I solved B.

44 = 2(24) - 4.

Combine the following expressions:
melisa1 [442]

ANSWER

(4n - 1)\sqrt{3 n} + 3\sqrt{n}

EXPLANATION

The given expression is

\sqrt{48 {n}^{3} }  +  \sqrt{9n}  -  \sqrt{3n}

We remove the perfect squares under the radical sign.

\sqrt{16 {n}^{2}  \times3 n}  +  \sqrt{9n}  -  \sqrt{3n}

We can now take square root of the perfect squares and simplify them further.

\sqrt{16 {n}^{2}}   \times \sqrt{3 n} +   \sqrt{9} \times  \sqrt{n}  -  \sqrt{3n}

This simplifies to:

4n\sqrt{3 n} + 3\sqrt{n}  -  \sqrt{3n}

This further simplifies to:

(4n - 1)\sqrt{3 n} + 3\sqrt{n}
