Answer:
Jose's solution is not correct, the auditorium has rows
Step-by-step explanation:
we have
where
f(x)------> is the total number of seats in the auditorium
x----> represents the number of rows
How many rows are there in the auditorium if it has a total of 416 seats?
so
Find the value of x for f(x)=416 seats
substitute the value of f(x) in the equation
Using a graphing calculator
The values of x are
The solution is
x=16 rows because the number of rows can not be a negative number
Answer:
Answer D
Step-by-step explanation:
The formula is . We have our r (radius) and h (height), so plugging it all in would give us A = (3.14)(5 + sqrt(12^2)+(5^2). After computing this, you would get answer D, 282.6.
Answer:
B. No.
Step-by-step explanation:
We have been given 3 side lengths 7 ft, 12 ft, 17 ft. We are asked to determine, whether the given set of lengths can form a right triangle or not.
We will use Pythagoras theorem to solve our given problem, which states that the square of hypotenuse of a right triangle is equal to the sum of squares of two legs of right triangle.
Since the sum of squares of both legs is less than square of hypotenuse, therefore, the given set of lengths can not be the side lengths of a right triangle.
