Answer:
D
Step-by-step explanation:
The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.
The entry in the 
row (start counting rows from 0) and 
column (start counting columns from 0) of Pascal's triangle is denoted by
Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.
Hence,
Answer:
width = 12 ft
Step-by-step explanation:
Given the figure of the pond and the fact that the corners form a right triangle that is across from the string of flags, you can use the Pythagorean Theorem to solve for the width of the triangle that is formed by the flags:
a² + b² = c², where 'a' and 'b' represent the legs of the triangle and 'c' represents the diagonal or hypotenuse. Using 16 for 'a' and 20 for 'c':
16² + b² = 20²
256 + b² = 400
Subtract 256 from both sides: 256 - 256 + b² = 400 - 256 or b² = 144
Take the square root of both sides: √b² = √144 or b = 12 ft
