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:
8n + 5 = 69
And that number is 8, because 8•8+5=69
Step-by-step explanation:
"eight times a number and five is sixty-nine" in this statement the words "a number" is the number we dont know and so we use a variable for it. I put n, but you could have used x or a or any variable. The "and five" indicates adding. The "is" indicates equals.
it's 51 but i would give brainlyst to the other person so yeah hope this help you :)
