Answer:
4 units
Step-by-step explanation:
Let ABC be isosceles right angled ∆ right angled at B
By Pythagoras theorem,
AC² = AB² + BC²
(√32)² = 4² + s²
32 = 16 + s²
s² = 32 - 16
s² = 16
s = √16
s = 4 units.
Therefore s = 4 units

Answer:
5 nights
Step-by-step explanation:
Solve the inequality:
90x + 90(0.1)x + 12x + 30 600
Add like terms:
102x + 30 + 90(0.1)x 600
Isolate the variables:
102x + 90(0.1)x 570
102x + 9x 570
111x 570
x 5.13
So, the Lincolns can stay for 5 nights without exceeding $600
