lukranit [14]

Answer:

0.4

Step-by-step explanation:

If the ratio of boys to girls in a class is 2:3, then

  • there are 2x boys;
  • there are 3x girls.

If there are 18 girls in the class, then

3x=18\\ \\x=6

Thus, there are

  • 2\cdot 6=12 boys;
  • 3\cdot 6=18 girls;
  • 12+18=30 students in total.

The probability of a boy being in the class is

P=\dfrac{12}{30}=\dfrac{2}{5}=0.4

Fiesta28 [93]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle.

Sum the sides and equate to 54, that is

3x + 4x + 5x = 54, that is

12x = 54 ( divide both sides by 12 )

x = 4.5

Thus

AB = 3x = 3 × 4.5 = 13.5 in

BC = 4x = 4 × 4.5 = 18 in

AC = 5x = 5 × 4.5 = 22.5 in
