Answer:
Your answer is 3.1
Step-by-step explanation:
Wherever you see j, substitute 5. Wherever you see k, substitute 3
1. Set up: 
2. Multiply 4.7 * 5, to get 23.5
3. Multiply 6.8 * 3 to get 20.4
4. Subtract 23.5-20.4
5. Final anwer - 3.1

Step-by-step explanation:
The ladder forms a triangle with the wall and ground.
The side of the triangle opposite of the 60° angle is 4 feet.
To find the length of the ladder (the hypotenuse), use sine.
sine = opposite / hypotenuse
sin 60° = 4 / L
L = 4 / sin 60°
L = 4 / (√3 / 2)
L = 8 / √3
L = 8√3 / 3
L ≈ 4.619 feet
To find the distance from the wall, use tangent.
tangent = opposite / adjacent
tan 60° = 4 / x
x = 4 / tan 60°
x = 4 / √3
x = 4√3 / 3
x ≈ 2.309 feet
Answer:
280
Step-by-step explanation:
<u>Change percentage into decimal:</u>
80% = 0.80
