There are 3 feet in 1 yard. 300 feet is equal to 100 yards.

2 pieces of rope at 16 yards = 32 yards

1 piece of rope at 12.5 yards = 12.5 yards

1 piece of rope at 123.25 feet, divided by 3 feet per yard = 41.1 yards (approx.)

100 - 32 - 12.5 - 41.1 = 14.4 yards

Now multiply by this number of yards by 3 to convert it to feet.

14.4 x 3 = 43.2 feet

The school club needs 43.2 feet of additional rope.

Answer:

35 tickets at $35, 72 tickets at $25

9x+5y=675

Substract

 9x+5y=675

The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.

2)A parabola has single focus and directrix

A hyperbola has two foci and two directrices

3)Eccentricity, e = 1(parabola)

Eccentricity, e>1(hyperbola)

4)The two arms present in a parabola should be parallel to each other

The arms present in hyperbola are not parallel to each other
