Answer:
18.8 billion dollars
Step-by-step explanation:
S - 1.7x = 5.2
x = 2006 - 1998 = 8
S - 1.7(8) = 5.2
S - 13.6 = 5.2
S = 5.2 + 13.6
S = 18.8
Answer: D
Step-by-step explanation:
Answer:
The answer is below
Step-by-step explanation:
The ramp has the form of a triangle. The height of the ramp is the vertical side of a triangle, the top of the frame is the hypotenuse while the length of the ramp is the base side of the triangle.
Let the hypotenuse be b, length be a and height be c Hence:
b² = a² + c²
b² = 3² + 5²
b² = 9 + 25
b² = 34
b = 5.83 feet
B) The plywood needs to be 5.83 feet long
C) Since the top of the ramp is 10 feet, let us assume the height of the ramp to be 6 feet, hence, the length of the ramp a is:
10² = a² + 6²
100 = a² + 36
a² = 64
a = 8 feet
