Answer:
81
Step-by-step explanation:
9 × 3n= 3^7
9×3n= 2187
27n= 2187
n= 2187/27
= 81
Hence n= 81
Answer:Multiply the base area times the height to find the volume, which is the amount of packing material required
Step-by-step explanation: example :An empty box is shaped like a rectangular prism. The box has a base area of `9/10` square foot and a height of `1/3` foot. How much packing material is required to fill the box?
First, multiply the numerators, or the top numbers. 9 * 1 = 9
Then, multiply the denominators, or the bottom numbers. 10 * 3 = 30
So, the amount of packing material required is 9/30 cubic feet.
Answer:
440 hours
Step-by-step explanation:
In this case the aircraft has completed one cycle of service in the first 454 hours of service. Then making the difference between the hours of service and the hours of the first cycle we have:
Hours of the second cycle= Total time in service- time Airworthiness Directive
=468-454=14
Then we have 14 hours of service and need to accumulate the rest to complete 454. It is
454-14=440
Then we need to accumulate 440 hours additional to complete the Airworthiness Directive .
Answer:
75 cm
Step-by-step explanation:
Perimeter of smaller rectangle = 45 cm
Perimeter of larger rectangle = 5/3 * 45 = 5*15 = 75 cm
The maximum rate of change occurs in the direction of the gradient vector at the given point, with magnitude equal to the norm of the gradient at that point.
