Arc length, (s)=(radius, r)(central angle, q)
s=rq
q=s/r
q=4/10
q=2/5, or 0.4 radians
Easy
when rock is in water, it takes up a certain volume, say x
so
initial+x=final volume
luckily we have final and inital
13.7ml+x=28.9ml
minus 13.7ml both sides
x=15.2ml
the volme of the rock is 15.2ml
Answer:
gas it's gas
trust me I have a 96.7% in science
To get percentage u take the percent u are trying find and divide it by 100 like 98percent and u get .98 then u would multiply .98 by 192 and u get 188.16 u do the same with the next two and u get 66.34 , 39.48
The answer would be D. For you to find the solution you would need to look at the x from the coordinates.
