Sin A =12/13
Answer:
60ml of the 50% alcohol solution and 20ml of the 6% alcohol solution
Step-by-step explanation:
We can build a system of equation for solve this problem
x = first solution
y = second solution
x + y = 80
0.5x + 0.06y = 80 * 0.39
x + y = 80
0.5x + 0.06y = 31.2
x = 80 -y
0.5(80-y) + 0.06y = 31.2
40 - 0.5y + 0.06y = 31.2
-0.44y = -8.8
y = 20
x = 80 - 20 = 60
Answer:
84
Step-by-step explanation:
37 + 47 = 84
Circle area is πrsq
So 3.14 x 1 squared = 3.14
3 x 3 = 9
9 - 3.14 = 5.858
5.858 rounded is 5.86
So the answer is 5.86
