<span>Let's assume the mat as a right triangle
Taking length of triangle be x
so height = x-21
and hypotenuse= x+6
for right triangle we can apply pythagoras theorem
so (x+6)^2=x^2+(x-21)^2
expanding we get
x^2 + 12 x + 36 = 2 x^2 - 42 x + 441
solving for x we get
x=9,45
But for length to be 9 height will be negative
So the length of mat will be 45 inches</span>
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
