Answer:
Both plans last for 1.25 hours (1 hour 15 minutes)
Step-by-step explanation:
Let x hours be the time needed for plan A and y hours be the time needed for plan B.
On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.
On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.
Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:
Therefore,
Answer:

According to the Pythagorean theorem, the square of the hypotenuse (the longest side) of a right-angled triangle equals to the sum of the squares of the other two sides. In this case, the ladder is the hypotenuse, which equals to the distance between the bottom of the ladder and the tree + the distance we want to find (x):
5² + x² = 13²
25 + x² = 169
x² = 144
x = √144 = 12.
The distance between the ground and the top of the ladder is 12 ft.
