To solve for the given problem above:
Let x be the number of boxes left after 3 hours
3 * ½ X = 24
3/2 X = 24
X = 24 * 2/3
X = 16
The correct answer is 16.
Answer:

Step-by-step explanation:
Given:
Vertex of the parabola is, 
Equation of the parabola in vertex form is given as:

Plug in
. This gives,

Therefore, the equation of the given graph is
.
Step-by-step explanation:
the side on the left of 155 is 180-155 which is 25
the one on top of 120 is 180-120 which is 60 so the one on the right of x is 180-(25+60) which is 95
now the value of x is 180-95 which is 85.
in the second one x=180-100 because the angle on the bottom of x is corresponding to the one that's equal to 100, so x=180-100 which is 80
for the first one x=85
the second one x=80
The answer is the third one: 32 inches
