first 80° and then 120° first 40° and then 60° first 60° and then 90° first 72° and then 108°
How many people are at the table?
oops my bad
but u skipped numbers?
I jumped from 10 to 12 for some strange reason
sorry I see where I added the extra number
ok yeah, 12
anyways, divide 360 degrees by 12 360/12 = 30
going from person to person means that you go 30 degrees along the outer arc
so going from Abbey to Kai means we go 2 spots (2 spots)*(30 degrees per spot) = 60 degree rotation
yeah but the next spot i over 180? if its 30 degree each spot
going from Kai to Haifa means we move 3 spots (3 spots)*(30 degrees per spot) = 90 degree rotation
its 2 spots and the 5 spots?
ohh i see lol
yeah it's starting from Kai on the second part (and not Abbey)
Okay do u know this one? Every _____ tessellates. pentagon octagon triangle decagon
the answer is given at the top of this page http://gabrielattar.weebly.com/uploads/4/3/2/2/43226303/12.6_tessaletions_notes_.pdf where it says "Theorem 12-6"
yay i got it right then
congrats on getting it right
A taxicab starts at (1, -2) on the grid and picks up a passenger. The taxicab travels a total of 16 blocks, and then drops the passenger off. Which composition of two translations could describe the taxicab’s final position? (x, y) > (x + 4, y - 3), and then (x, y) >(x - 9, y + 1). (x, y) > (x - 4, y + 3), and then (x, y) > (x + 6, y - 1). (x, y) > (x - 3, y + 4), and then (x, y) > (x + 8, y - 1). My answer (x, y) > (x - 3, y + 4), and then (x, y) > (x + 7, y - 1).
good, choice C is the only one where the total distance traveled is 16 blocks
So im right!?
In the diagram, triangle ECD is a _____ of triangle ABC across line p.
translation glide reflection rotation reflection (my guess)
let me think
the reflection does not line up with ECD so reflection doesn't work I couldn't get glide reflection to work either
translation doesn't work either the only thing left is rotation. The only issue is that I'm not sure how they're rotating it. This problem is just odd
if line p were along BC, then a glide reflection would work but that's not the case since line p is through EC
I think the authors messed up
All i can guess is relfection
A blueprint for a fence has a scale of 1:40. The fence in the blueprint is 6 in. What is the length of the actual fence? 20 feet 240 feet (or this one) 20 inches (my answer) 72 feet
"has a scale of 1:40" means that you multiply the smaller dimension (6 inches) by 40 to get the corresponding longer dimension then convert to feet
Yeah. 6*40=240 240/12 = 20 right?
