He climbes 1 1/4 miles.
1/4+1/4+1/4+1/4+1/4= 1 1/4.
Answer:
(2,-4)
Step-by-step explanation:
You can use substitution
We know that y=2x-4
2x+5(2x-4)=16
2x+10x-20=16
12x-20=16
12x=36
x=3
Solve for y
Y=2x-4
Y=2(3)-4
Y=6-4
Y=2
The solution is(3,2)
Answer:
72°
Step-by-step explanation:
The string, pole, and ground form a right triangle. The hypotenuse of this triangle is 160 feet. The base of the triangle is 50 feet. The angle adjacent to the base can be found with cosine:
cos x = 50 / 160
x = acos(50 / 160)
x ≈ 72°
