R = rate of growth of raindrop vine = 0.75 feet/day
we know that : 1 feet = 12 inches
1 day = 24 hours
replacing the units accordingly in the above expression for rate of growth of raindrop vine
R = 0.75 (feet/day) (12 inches/1 feet) (1 day/24 hours)
R = (0.75 x 12 /24) (inches/hour)
R = 0.375 inches/hour
Answer: 10 units²
Step-by-step explanation:
We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.
We can get each triangle's area using the formula 
<h3>Left Triangle</h3>
base length - 4 units
height - 4 units


<h3>Right Triangle</h3>
base length - 2 units
height - 2 units



Total = 8 units² + 2 units² = 10 units²
The answer is -6 degrees Celsius
