Answer:
14
Step-by-step explanation:
4x-29+ 5x-9= 7x -10
4x+5x-29-9=7x-10
9x-38=7x-10
9x-7x=38-10
2x=28
x=28/2
x=14
The relationship between the height and shadow length is a direct proportionality type of relationship. That is, the higher the height, the longer the shadow and vice versa. The ratio of height to shadow length is a constant.
Therefore, if x and y are are the length of shadow of tether ball pole and flagpole receptively,
=
=> y=
When x= 1.35 m
y=(6.8/3)*1.35 =3.06 m
When x=1.8 m
y= (6.8/3)*1.8 = 4.08 m
When x= 3.75 m
y=(6.8/3)*3.75 = 8.5 m
When x= 0.6
y= (6.8/3)*0.6 = 1.36 m
When x=2
y= (6.8/3)*2 = 4.533 m
Therefore, it is true that B and D are the true answers.
