Answer: 4 feet
Step-by-step explanation:
An airplane is 180 feet long.
Blake makes a scale model of the airplane which is 1:45 of its actual size. To find the length of the airplane model goes thus:
= 1/45 × 180
= 4 feet
The model is 4 feet
The most important thing here is converting the length into the same units. So:
3 feet 9 inches = 45 inches
now, we know that compound 'growth' can be worked out by multiplying the initial value by the decimal to the power of the years. So, relating to this question, the equation would be:
5 x α⁴ = 45
Now, we have to solve for α!
α⁴ = 45/5
α⁴ = 9
α = ⁴√9
α = 1.732050808
This is the increase every year written as a decimal so, if we want to work out the pure percentage, we have to subtract 1 and then multiply by 100:
1.732050808 - 1 = 0.732050808
0.732050808 x 100 = 73.20508076
Rounded to 2 decimal places the answer would be 73.21% !

Answer:5
Step-by-step explanation:
This can be solved by fixing the position of shortest and tallest person in the first and second row respectively .
Rest we have four person remaining and we have to arrange 4 person in 4 positions therefore we can do it in
ways out of which we have to exclude the case when both the tall persons is in the first row and short person in second rows
Therefore a total of 6-1 ways is possible
