<span>Use the formula below to find the volume of the beach ball.
Remember that the radius is one-half of the diameter.
 V=3/4 pi r^3 =4/3(3.14)(9 in)^3 =3,052.08
Therefore, the beach ball has a volume of 3,052.08 cubic inches when it is completely full.

The airplane in the scale drawing has a wingspan of a feet and a tail span of b feet. If the tailspin in the drawing is 2 inches
xeze [42]

Correct answer is: actual wingspan of airplane is 6 inches.

Solution:-

We are given that wingspan is 'a' feet and tail span is 'b' feet in a scale drawing.

And we are also given that tail span is 2 inches that is b=2 inches and \frac{a}{b}=3

Let us plugin the b value in above equation.

\frac{a}{2}=3

Multiplying with 2 on both sides.

a=3X2=6 inches.

Hence actual wingspan of airplane is 6 inches.

Answer:

Step-by-step explanation:

Equation

3x + 9 + 2x = x - 2x - 3              

Solution

Combine all the like terms.

3x+2x+9 =  x - 2x - 3

5x + 9 = -x - 3                            Add x to both sides of the equation

5x+x +9 = -x+x -3                      Combine

6x + 9 = - 3                                Subtract 9 from both sides of the equation

6x+9-9 = - 3-9                           Combine

6x = -12                                      Divide both sides by 6

6x/6 = -12/6

x = - 2

Answer x = - 2

Solve the equation.<br><br> 2 ( 4z - 1) = 3(z+2)<br><br> Z=
sveta [45]

Answer:

z = \frac{8}{5}

Step-by-step explanation:

Calculate for the value of z :

2(4z - 1) = 3(z + 2)

-Use <u>Distributive Property</u> on both left and right:

2(4z - 1) = 3(z + 2)

8z - 2 = 3z + 6

-Take 3z and subtract 8z :

8z - 3z - 2 = 3z - 3z + 6

5z - 2 = 6

-Add 2 to both sides:

5z - 2 + 2 = 6 + 2

5z = 8

-Take 5z and divide on both sides:

\frac{5z}{5} = \frac{8}{5}

z = \frac{8}{5}

Therefore, the value of z is \frac{8}{5}.
