7. Stretch your arm out straight in front of you and hold your thumb straight up. Close one eye and look at a distant object.
Without moving your arm (or thumb), switch eyes. What
appears to happen? Measure the distance between your eyes
and the distance between one eye and your thumb. Explain
how, with one other piece of information, you can now use
similar triangles to estimate the distance to the distant object.
What else do you need to know?

50- 250 is correct i did that one too

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

hope this : )

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
