The golf clubs have been sorted into woods and irons. the number of irons is four more than two times the number of woods. the equipment is 75% irons. how many woods are there?
4
5
6
7

Let no of woods be x

no of irons= 2x+4

Equipment contains 75% iron

2x+4 = 0.75 ( x+2x+4)

2x+4 = 0.75x + 1.5x +3

2x+4 = 2.25x + 3

0.25x = 1

x= 4

No of woods = 4

4

Step-by-step explanation:16/4 = 4

if 75% of equipment is iron then do the math

So it would be 4(2) + 4 = 75% of 16
So if 75% of 16 is 12 you need that extra 4 to get you to 16

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
