Answer:
the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.
Step-by-step explanation:
It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2
Okay so you're trying to find the unit rate of 720yds/4min. If you divide 720 by 4 you will have the unit rate as 180yds/1 min or 60 sec then if you divide 180 and 60 by 4 again you will get the answer of 45yds/15sec.
The answer is 7b+35 because the seven multiplies by the b and the 5 meaning that you multiple the number that’s on the outside with what’s on the inside and be b is a variable it cannot be multiplied so you combine 7 and b which gives you 7b and then you multiply 7 and 5 which gives you 35
