Answer:
Davide is 10 years old.
L'età di Davide è 10.
Step-by-step explanation:
The average ages of Aldo, Bruno, Carlo, and Davide amount to 16 years.
Let’s denote:
x for Aldo's age.
y for Bruno's age.
z for Carlo's age.
w for Davide's age.
The average for all four is 16 years.
This gives us:
Excluding Davide, the average age of the other three is 18. Therefore:
Substituting into the original equation:
Hence, Davide’s age is indeed 10.
L'età di Davide è 10.
The statue's height is 152 feet. To answer this question: The total height of the Statue of Liberty alongside its pedestal is 305 feet, which is 153 feet more than the statue’s height. You can derive the height h of the statue using the formula.
There exist two coefficients: one pertains to x raised to the first degree, and another corresponds to the zeroth degree of x (the constant term).
Thus:
the coefficient for the constant term is 42 (i.e. 42x^0=42).
the coefficient for the linear term is 2 (i.e. 2x^1=2x)
For the first film he may pick any of 6 options; once that choice is made, 5 remain for the second, then 4 for the third, and so forth.
Hence the total is 6! = 6*5*4*3*2 = 720 possible orders
