Step-by-step explanation:
Answer:
14.4 miles
Step-by-step explanation:
Given that :
Distance moved North = 12 miles
Distance moved West = 8 miles
Shortest distance to reach starting point :
Let shortest distance to reach starting point = d miles
Using the relation :
Longest side of a right angled triangle:
d = sqrt(8^2 + 12^2)
d = sqrt(64 + 144)
d = sqrt(208)
d = 14.422205
d = 14.4 miles (nearest tenth of a mile)
Answer:
70 yards
Step-by-step explanation:
we know that
The perimeter of the rectangular pen is equal to
we have
The width is between 10 and 20 yards inclusive
we know that
The longest pen will be for the smaller value of W
so
For W=10 yd
substitute in the equation of perimeter
solve for L
