Answer:
The length of the third piece of the ramp is;
D. 9.24 feet
Step-by-step explanation:
The given parameters are;
The height of the ramp = 8 feet
The angle between the piece that forms height and the base = 90°
The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°
Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;
Therefore, we get;
The length of the third piece, r ≈ 9.24 feet
50-degree temperature is 0 minutes to heat = 50/0 = 50
60-degree temp. is 1 minute to heat = 60/1 = 60
70-degree temp, is 2 minutes to heat = 70/2 = 35
80-degree temp. is 3 minutes to heat = 80/3 = 26 2/3
90-degree temp. is 4 minutes to heat = 90/4 = 22.5
100 degree temp. is 5 minutes to heat = 100/5 = 20

Answer:
Price in Japan= 17.81
Price in Switzerland = 13.58
Step-by-step explanation:
First set up system of equations
80.59 = 3j +2s
76.36 = 2j + 3s
Make it to where you can eliminate one variable
161.18 = 6j +4 s
-229.08 = -6j - 9s
Reset the problem
-67.9 = -5s
s=13.58
Re plug them in to the original equation to get j = 17.81
Y= 1,100
Explanation
9,787-8,687=1,100
