alisha [4.7K]

Answer:

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Step-by-step explanation:

  • Math session = 45 min = 3/4 hr
  • French session = 30 min = 1/2 hr
  • Number of math sessions = m, total math hours = 3/4m
  • Number of French sessions = f, total French hours = 1/2f

<u>Total hours constraint:</u>

  • 3/4m + 1/2f ≤ 30

<u>Number of session constraint:</u>

  • f ≤ 30

<u>So the system is:</u>

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Marysya12 [62]

Answer:

1. 18.84 in

2. 56.52 cm

Step-by-step explanation:

The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.

1. C = πd = π(6) = 3.14(6) = 18.84 in

2. C = 2πr = 2(3.14)(9) = 56.52 cm
