Answer:
Surface area = 850 cm²
Volume = 1000 cm³
Step-by-step explanation:
Applying,
A = h(a+b+c+d)................ Equation 1
Where A = Surface area of the trapezoidal prism, a, b, c, d = length of the four sides the trapezium respectively, h = height of the prism.
From the diagram in the question,
Given: h = 25 cm, a = 6 cm, b = 14 cm, c = 7 cm, d = 7 cm
Substitute these values into equation 1
A = 25(6+14+7+7)
A = 25(34)
A = 850 cm²
From the volume,
V = A'h...................... Equation 2
Where A' = Area of the base.
From the diagram,
A' = 1/2(6+14)4
A' = 40 cm²
Therefore,
V = 40×25
V = 1000 cm³
<h2>
Answer:</h2>
720 pounds
<h2>
Step-by-step explanation:</h2>
Initially, we have that the amount of algae in the pond is 
. Every four hours the amount of algae doubles. If we called 
the time and 
the amount of algae, we have that:
Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>
You would have to figure out what x would be... I use trial and error because i don't really know a better way to do it
The answer is c because there asking for the rate of change which is $20 per month
The answer is C
hoped this helped!
