Answer:

(b) 80/3π in³

Step-by-step explanation:

The volume of a circular cone is given by ...

V = 1/3πr²h . . where r is the radius (half the diameter) and h is the height

Your cone has r = 4 inches and h = 5 inches, so its volume is ...

V = (1/3)π(4 in)²(5 in) = 80/3π in³

The volume of the cone is exactly (80/3)π cubic inches.

The volume of a cylinder is 196pi in. cubed and the height of the cylinder is 1 in. What is the radius of the cylinder?

Free_Kalibri [48]

Answer:14in

Step-by-step explanation:

volume(v)=196π

Height(h)=1

Radius=√(v ➗ π x h)

Radius=√(196π ➗ πx1)

Radius=√(196)

Radius=14in

A certain amount of money is shared between

ICE Princess25 [194]

<h3>Hello There !! </h3>

<h3><u>Explanation :- </u></h3>

• Amount received by Rui = 5x = 5 x 11 = $55..

• Amount received by Vishal = 9x = 9 x 11 = $99..

Let the amount received by Rui be 5x..

Then the amount received by Vishal is 9x ..

And by this data = 5x + 44 = 9x ..

4x = 44
x = 44/4 = 11

• Amount received by Rui = 5x = 5 x 11 = $55..

• Amount received by Vishal = 9x = 9 x 11 = $99..

<h3>Hope this helps you..! </h3>

Simplify expression:<br> 3^{−(4a+1)} −3^{−(4a−1)} + 3^{−4a}

lyudmila [28]

$3^{-(4a+1)}-3^{-(4a-1)} + 3^{-4a} =3^{-4a-1 }-3^{- 4a+1 } + 3^{-4a}=\\ \\=3^{ -4a }*3^{-1}-3^{ - 4a }*3^1 + 3^{-4a} =3^{-4a}(3^{-1}-3+1)=3^{ -4a }*(\frac{1}{3}-2)=\\ \\=3^{ -4a }*(-1\frac{2}{3})=3^{ -4a }*(-\frac{5}{3})=3^{ -4a }*(-5)*\frac{1}{3} =-5 *3^{ -4a }*3^{-1}=\\ \\ =-5 *3^{ -4a +(-1)}=-5 *3^{ -4a -1}$

Which of the following is the solution to the compound inequality below?<br> 3x+5 2 -1 or -2x - 725

sashaice [31]

Answer:

x= -674

Step-by-step explanation:

Solve for x and check: x + 5 = 3

Solution

Solve for x and check: - 3x = 12

Dividing each side by -3, we obtain

Another way of solving the equation

3x - 4 = 7x + 8

would be to first subtract 3x from both sides obtaining

-4 = 4x + 8,

then subtract 8 from both sides and get

-12 = 4x.

Now divide both sides by 4 obtaining

- 3 = x or x = - 3

Solve for c: 3(x + c) - 4y = 2x - 5c

First remove parentheses.

Remember, abx is the same as 1abx.

We divide by the coefficient of x, which in this case is ab.
