Answer:
Third one
Step-by-step explanation:
30x would be 30 times the amount of fish (x)
+ 80y would be 80 times the amount of octopus captured (y)
- 15z would be subtracting 15 times the amount of crabs she captures
93 * 20 / 120 = 15.5

Answer:
Step-by-step explanation:
A = ½(5.5)(6.4) + ½(5.5)(5.2)
A = ½(5.5)(6.4 + 5.2)
A = ½(5.5)(11.6)
A = 31.9 in²
Answer:
<em>The other dimension is x=4 cm</em>
Step-by-step explanation:
<u>Surface Area of a Rectangular Prism</u>
Given a rectangular prism of dimension x, y, and z. Its surface area is calculated with the formula:
A = 2(xy + yz + xz)
We are given the dimensions y=5 cm and z=6 cm. We also have A=148 cm2. Substituting:
148 = 2(x*5 + 5*6 + x*6)
Dividing by 2:
74 = x*5 + 5*6 + x*6
Operating:
74 = 5x + 30 + 6x
Simplifying:
74 = 11x + 30
Subtracting 30:
44 = 11x
Dividing by 11:
x = 4 cm
The other dimension is x=4 cm
