Answer:
i think E.942 cm³ is answer
Volume = πr²h
so
3.14×5×5×12
= 942 cm²
Cos 28 = 18/ y
so
y = 18 / cos 28
y = 18 /.8829
y = 20.4
8) x represents the number of pounds of peanuts, and y represents the number of pounds of raisins
9)
Solve:
x+2y=9
-2y -2y
x=9-2y
2(9-2y) + 3y=14
18-4y+3y=14
-18 -18
-y=-4
y=4
x+2(4)=9
x+8=9
x=1
