Answer:
Step-by-step explanation:
Let the distance be 
and the time be 
.
It was given that the distance, , varies directly as the square of the time , we write the proportional relation,
.
, where 
is the constant of variation.
It was also given that, 
, when 
.
Now the equation of variation becomes;
When, 
, 
The object will travel 301865 feet in 55 seconds.

Answer:
x=12
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + x^2 = 15^2
81 + x^2 = 225
Subtract 81 from each side
x^2 =225-81
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x=12
