Does anybody go to Connexus and take Geometry B in 10th Grade?
Plots of land between two roads are laid out according to the boundaries shown. The boundaries between the two roads are parallel. What is the length of Plot 3 along Cheshire road?
@amistre64
the only way this makes sense to me is if all the plots are "similar"
if they are similar, then we can conclude that 48n = 56 40n = length desired
Okay so should I just say they are similar. The answer choices are A. 46 2/3 yards B. 67 1/5 yards C. 66 yards D. 37 1/3 yards @amistre64
we can gather from the information, that they are similar. As such, they have a similar ratio. 48 scales to 56, and 40 scales to (something) as such, we can find the scalar to multiply by. 48n = 56; therefor 40n=(something) find n to solve for the (something) we want to know
How do I find n?
48n = 56, is a simple algebra process ....
48, times 'what', is equal to 56?
1.16
close enough :) so, 40(1.16) will get us close enough to what the answer is as well
46.4
then what we want for an answer will be 46, and a little bit ....
So, A?
A seems good to me yes
Can you help me with one more question?
I need to find the geometric mean of 275 and 11.
what is 275*11?
3025
to find the GEO mean, we then take the sqrt of it what is the sqrt of 3025?
55
then 55 it is
Thank you so much :)
