A pizza is divided into 30 equal pieces. Violet and Sophie each ate one sixth
erastovalidia [21]

Answer:

12.5 or 12 1/2 Slices left

Step-by-step explanation:

30 divided by 6 or (1/6) is 5

So,

Violet ate 5

Sophie ate 5 (same amount)

30 divided by 5 or (1/5) is 7.5

so we add 5+5+7.5 = 17.5 and subtract it from 30 to get our left over slices which comes up to

12.5 or 12 and 1/2 slices

hope this helps

PLEASE HELP which of the following identities? Check all that apply
alisha [4.7K]
\sin(x - \pi) = \sin(x) \cos(\pi) - sin(\pi) \cos(x)
via the angle sum formula of sin
since \: cos(\pi) = - 1 \: and \: sin(\pi) = 0 \: then \\ sin(x - \pi) = - sin(x) \: which \: proves \: the \: first \: choice

\cos(x + y) + cos(x - y) = 2 \cos(x) \cos(y) =\:cos(x + y) + cos(x - y)=cos(x) cos(y)-sin(x)sin(y) +cos(x)cos(y)+sin(x)sin(y)=2cos(x)cos(y)
which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true
