They can line up 20 different ways
Answer:
D.
Step-by-step explanation:
Answer - 42 Sandwiches
Explanation -
56 is what you start out with. you will need to find 25% of those 56 to see the remaining. So 25% of 56 is 14 because .25 x 56 is 14. You then subtract 56 from the 14 Tuna sandwiches and you’re left with 42.
R represents radius or the distance between two points, the pythagorean expression will be
r² = Δx² + Δy²
Δ means the change, Δx means the change of x, Δy means the change of y
Given:
(x₁,y₁) = (-5,-1)
(x₂,y₂) = (0,2)
Input the numbers to the expression
r² = Δx² + Δy²
r² = (x₂ - x₁)² + (y₂ - y₁)²
r² = (0 + 5)² + (2 + 1)²
r² = 5² + 3²
r² = 25 + 9
r² = 34
r = √34
The distance is √34 unit length
