Answer:
123 km/h
Step-by-step explanation:
the formula for the unit rate would be 82/40
82 divided by 40 is 2.05km/m
Then you have to convert 2.05 km/m to km/h
multiply 2.05 times 60 and your answer is 123 km/h

Answer:
When the input is 6, the output must be 12.
Step-by-step explanation:
f(6) = 12
The input to the function is x which is 6 and the output is what f(6) equals which is 12
Answer:
C. 439.6 in.²
Step-by-step explanation:
The container is a cylinder.
Since the two circular bases won't be covered, therefore:
The least construction paper needed to cover the remaining surface = curved surface area of the cylinder
= 2πrh
r = 5 in.
h = 14 in.
Plug in the values
Curved surface area = 2×π×5×14 = 439.6 in.²

Step-by-step explanation:
<u>Step 1: Define</u>
-12(x + 4) + 14x = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -12: -12x - 48 + 14x = 60
- Combine like terms: 2x - 48 = 60
- Add 48 to both sides: 2x = 108
- Divide 2 on both sides: x = 54
