15.

I had x before the movie.

x - 13.50 = 26.50

Add 13.50 to both sides of the equation:

x = 40

I had $40 before the movie.

16.

The original balance was x.

x - 161.15 = 423.28

Add 161.15 to both sides:

x = 584.43

The previous balance was $584.43

Find the volume of the solid where the cone and half sphere are hollow. Use 3.14 for П ; height is 19 in; radius is 5 in. Round
Vera_Pavlovna [14]

Volume of Solids

The volume of the solid is 758.83 in³

Step-by-step explanation:

Given that the cone and half sphere is hollow

The volume of the cone = 1/3 \pi r^{2} h\\

The Volume of the sphere  = 4/3 \pi r^{3}

So the Volume of the half sphere =2/3\pi r^{3}

The volume of solid = volume of cone + volume of the half sphere

V = V_{1}  + V_{2}

Given

height h = 19 in

radius r = 5 in

V_{1\\}  = 1/3 \pi r^{2} h

     = 1/3 × 3.14 × 5 × 5 × 19

     = 497.16 in³

V_{2}  =  2/3 \pi r^{3}

   = 2/3 × 3.14 × 5 × 5 × 5

   = 261.67 in³

V =  497.16 in³ + 261.67 in³

  = 758.83 in³

Hence the volume of the solid is 758.83 in³

We can use the Pythagorean theorem to find the answer

The lengths in the problem form a right triangle with a hypotenuse of 20ft and legs of 16ft and the horizantal distance

400-256 = 144

✓144 = 12

Suppose f(x)=2x-5 and g(x)=|-3x-1|.<br> Find the following value.<br> 2g(-4)=??
Tema [17]
When x = -4,
g(-4) = |-3*(-4) - 1| = 11

So, 2g(-4) = 2 * 11 = 22

[Where * represents multiplication.]
