Answer:
Part A
The required wood for the ladder is 98 feet
Part B
The cost of the wood is 49,000
Step-by-step explanation:
Part A
The dimensions of the ladder to be made with wood are;
The distance between each step of ladder = 1 foot
The length of the ladder = 25 feet
The width of the ladder = 2 feet
The required wood = 2 × 25 feet/rail + 2 feet/steps × 24 steps = 98 feet
The required wood for the ladder = 98 feet
Part B
The cost of the wood = 500/foot × 98 feet = 49,000
The cost of the wood = 49,000

Answer:
26 square feet
Step-by-step explanation:
When two of the trapezoids are combined to make a parallelogram, the height remains the same (4 ft), but the width is the sum of the base lengths, 10 ft + 3 ft = 13 ft.
The area of the combined trapezoids is ...
A = bh = (13 ft)(4 ft) = 52 ft^2
The area of one trapezoid is half that, so is ...
A = (52 ft^2)/2 = 26 ft^2 . . . . area of the trapezoid
we are adding 4 each time
10+4 = -6
-6 + 4 = -2
-2+4 = 2
2+4 =6
6+4 = 10
10+4 = 14
14+ 4=18
The 7th term is 18
