Tore A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function
c
c
(
n
n
) = 2.5
n
n
, where
n
n
is the number of boxes for Store A and
n
n
is the number of pounds of rice for Store B.

The domain of
c
c
(
n
n
) = 2.5
n
n
is all the real numbers.

For each store, drag the restriction needed on values of
n
n
for
c
c
(
n

) to model each situation.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

The median segment divides the triangle into 2 isosceles triangles and everything else is trivial.|ad|=|bc|2=|bd|soδadb  is isosceles with∠dab=∠dbasimilarlyδadc  is isosceles with  ∠dac=∠dca∠cab=∠cad+∠bad=∠acb+∠abctherefore∠cab  is a right angleandbc  is the hypotenuse of a right-angled triangle.hope this

A67 it might be it or c 67
