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.

Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70
Answer:
x=9
Step-by-step explanation:
To solve for x, you can set up a proportion between the 2 triangles we see.
The small triangle can be written as , and the large triangle can be written as .
Set both proportions equal to each other.
Cross multiply and solve for x.
32x+272=560
32x=288
x=9
