Rick bought 5 pounds of steak.
Step-by-step explanation:
Given,
Cost per pound of steak = 13.50
Cost per pound of chicken = 3.25
Total bought = 8 pounds
Total paid = 77.25
Let,
x represents the pounds of steak purchased
y represents the pounds of chicken purchased
According to given statement;
x+y=8 Eqn 1
13.50x+3.25y=77.25 Eqn 2
Multiplying Eqn 1 by 3.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 10.25

<h2>Answer:</h2><h2>The angle of depression from the hiker to his car, Θ = 56.39 degrees</h2>
Step-by-step explanation:
A hiker at the top of a mountain spots his car back in the parking lot at the
bottom of the trail. If the trail is 632 meters long and the mountain is 420
meters tall,
opposite side = 632 m
adjacent side = 420 m
Angle of depression, Θ = arctan
= arctan
Θ = 56.39 degrees
