Mistura = 26 ml + 104 ml = 130 ml
130................100%
26.....................x
130x = 260
x = 260/130
x = 2 --> 2% de álcool
Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)
ANSWER

EXPLANATION
The basic sine function is

The transformed sine function has equation

where a=1 is the amplitude
2π/b=2π is the period
c/b= 4 is the horizontal shift 4 units left.
d=-4 is a downward vertical shift of 4 units.
The required sine function is:

24 × 9 (48Cans) = 9:48
12 × 10 (48Cans) = 10:48
12 × 9 (36Cans) = 9:36
Thirty seven square units
