Answer:
36) C, 790 m²
37) D, 625 in²
Step-by-step explanation:
To find the volume of a rectangular prism, we will multiply the length, width, and height together. The dimensions of the aquarium are 22.9×7.5×4.6. Multiply these together.
22.9 · 7.5 · 4.6 = 790.05
The volume is 790.05 m². This rounds down to 790 m², so the answer is C.

For the next question, the dimensions aren't given. Instead, we need to calculate them from the sidelengths of the unit cubes. Multiply 2.5 by the number of units on the length, width, and height of the prism. So, the dimensions are 10×12.5×5. Find the product of these dimensions.
10 · 12.5 · 5 = 625
The volume is 625 in². The answer is D.

Answer: CI = (0, 8)
Step-by-step explanation: Confidence interval for difference between mean is given below as
Lower limit
= (x1 - x2) + margin of error
Upper limit
= (x1 - x2) - margin of error
where x1 - x2 = 8 and margin of error = 8
For lower limit,
= 8 - 8 = 0
For upper limit
= 8 + 8 = 16
Hence CI = (0, 8)
Answer:
the answer is 5
Step-by-step explanation:
20 a: x = 5
20 b: x = 12
17 c: 30
Answer:
The numbers are 12 and 36
Step-by-step explanation:
x + y = 48
x - y = 24
Add y to both sides of the equation
x = 24 + y
Substitute new value for x into first equation
24 + y + y = 48
Add y's together
24 + 2y = 48
Subtract 24 from both sides of the equation
2y = 24
Divide both sides of the equation by 2
y = 12
48 - 12 = 36
The numbers are 12 and 36
Hope this helps :)
