Answer 2

do they give u answers to pick?

Answer 3

@lhxza2 theyre A) 1/6 ...B) 1/4.....C) 2/3.....D) 3/2..... E) 3/4

Answer 4

u want the answer?

Answer 5

@lhxza2 yup lol

Answer 6

ok its c 2/3

Answer 7

@lhxza2 thank you !

Answer 8

@jdoe0001 hey again, do you have an idea?

Answer 9

ur welcome

Answer 10

well.. there's the assumption that AB = 1 and thus AD = 2/3AB = 2/3
since your choces are not in "AB terms"


so the same, you'd use the arc's length formula

so, we could say for the arcBC, the radius is AB = 1
thus you have the radius and angle, plug and chug

for the arcDE, the radius is 2/3
thus you also have the angle and radius, thus plug and chug :)

Answer 11

arc's length = \(\large s = r\theta\)

Answer 12

@jdoe0001 thank you, I just wanted to double check lol. btw tell me when Im asking for too much.

Answer 13

hmm ok... wait.. they'd want the ratio of arcBC to arcDE... well... get the arc's length first
then simplify

Answer 14

Answer 15

@jdoe0001 A toy company manufactures sealed cubes that contain a colored liquid
that glows in the dark. The liquid completely fills the cubes. If 8 cubic
blocks with a side length of 1/6 m are needed to find the volume of
each cube, how much of the liquid can each cube hold?

hmm tis easy posting anew... more eyes :)
