First the surface area of the cube. Round to the nearest whole number and the next one after that pllzzzzz
1 answer:
To find a surface area of a cube you want to find the area of ONE side first. Since we know that the area of a square is 
, and we know that the side is 8.5, we can square it.
= 72.25
Since the area of one side is 72.25, and the number of sides in a cube is 6, we should multiply 72.25 by 6
=433.5
Your answer for the first problem should be 433.5 if I am not mistaken.
The second problem simply asks to write the fraction as a repeating decimal
17/7 = <span>2.428571428571
We can see that the decimal digits of 428571 repeats, you would put the bar over it. Good luck!</span>

Answer:
1.96 planes
Step-by-step explanation:
The computation of the number of planes is shown below:
As we know that
System Inventory is
= Flow rate in the system × Throughput time
where,
Flow rate is
= Frequency of taken off
= 16 planes ÷ hour
= 16 ÷ 60 Planes per minute
Throughput time is
= runway waiting time + runway Run time
= 33 seconds + 6 minutes × 60 seconds + 48 seconds
= 441 seconds
= 441 per 60 seconds
Therefore the number of planes is
= 1.96 planes
