Answer:

48√3 cm

Step-by-step explanation:

I'm assuming that ∠A = 30°, ∠R = 60°, and ∠Y = 90°.

The sides of a 30-60-90 triangle are in the ratio 1:√3:2.

RY is opposite the 30° angle and has length 48 cm.

AY is opposite the 60° angle, so the length of AY = 48√3 cm.

Answer:

  • golf: $10
  • batting: $2.50

Step-by-step explanation:

We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.

  5g +4b = 60 . . . . . Sylvester's expense

  3g +6b = 45 . . . . . Lin's expense

Dividing the second equation by 3 gives ...

  g +2b = 15   ⇒   2b = 15 -g

Substituting into the first equation, we have ...

  5g +2(2b) = 60

  5g +2(15 -g) = 60 . . . . . substitute for 2b

  3g = 30 . . . . . . . . . subtract 30, collect terms

  g = 10 . . . . . . . divide by 3

__

  2b = 15 -10 = 5 . . . . use the value of g to find b

  b = 2.5 . . . . . . . . divide by 2

Mini golf costs $10 per round; batting cages cost $2.50 per turn.

How can you write repeating decimals as fractions?
Burka [1]
Rewrite the decimal as a fraction by putting that number as the numerator and the denominator would be how many times the number has repeated originally.

I hope this helped you!
