Professor Stache awarded 500 certificates, some for math, and some for science. Girls won 2/3 of the math certificates and 1/2 o
wariber [46]

Answer:

  • 200

Step-by-step explanation:

<u>Given:</u>

  • Total certificates = 500
  • Math = m
  • Science = s

<u>Equations </u>

  • m+s = 500  ⇒ s = 500 - m

<u>Girls who won certificates:</u>

  • 2/3m = 50 + 3/2*1/2s
  • 2/3m = 50 + 3/4s

<u>Multiply both sides by 12 to clear fractions</u>

  • 8m = 600 + 9s

<u>Substitute s</u>

  • 8m = 600 + 9(500 - m)
  • 8m = 600 + 4500 - 9m
  • 17m = 5100
  • m = 5100/17
  • m =300

<u>Girls who won math:</u>

  • 2/3*300 = 200

AleksAgata [21]

Answer:

For each player:

Headbands = 11.67 inches of fabric

Wristbands = 9.31 inches of fabric

Step-by-step explanation:

Shauna is making accessories for the soccer team

For Headbands

She uses 513.48 inches of fabric on headbands for 40 player and 4 coaches

The total number of persons = 40 players + 4 coaches

= 44 persons

Hence:

44 persons = 513.48 inches

1 person = x

Cross Multiply

44x = 513.48 inches × 1

x = 513.48 inches/44

x = 11.67 inches per person

For Wristbands

She uses 372.40 inches of fabric on wristbands for just the players how much fabric was used on a headband and wristband for each player?

Number of players = 40

Hence

40 players = 372.40 inches

1 players = x inches

Cross Multiply

40x = 372.40 inches

x = 372.40 inches/40

x = 9.31 inches

Hence, 9.31 inches per player.

Therefore

For each player:

Headbands = 11.67 inches of fabric

Wristbands = 9.31 inches of fabric
