In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig
horrorfan [7]

Answer:

  (b)  24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

  LH males = 4 × LH females = 4x

  RH females = 3 × RH males = 3y

  LH males + RH males = 204 = 4x +y

  RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

  (x, y) = (24, 108)

There are 24 left-handed females.

__

<em>Additional comment</em>

Other numbers involved here are ...

  y = 108 . . . . right-handed males

  204-108 = 96 . . . . left-handed males (=4×24)

  348-24 = 324 . . . . right-handed females (=3×108)

__

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

  3(204 -4x) +x = 348   ⇒   -11x = -264   ⇒   x = 24

The answer is 16 pi - 16. The area of each triangle is 8, so both triangles are 16. The area of the circle is pi times the radius squared, 16 pi.

Pankaj gets ice cream in a cone that is 6 inches tall and has a radius
Arisa [49]

The volume of the ice cream is  72.03 in³.

<h3>What is the volume of the ice-cream?</h3>

The volume of the ice cream is the sum of the volume of the cone and the volume of the hemisphere.

volume of the cone = 1/3πr²h

1/3 x 22/7 x 2.5² x 6 = 39.29

Volume of the hemisphere = 2/3πr³

2/3 x 2.5³ x 22/7 = 32.74

The volume of the ice cream = 39.29 +  32.74 = 72.03 in³
