Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
Answer:
here is how to do it
Step-by-step explanation:
The car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet.
In order to determine the distance that the car has travelled, we will use the formula for calculating the circumference of a circle.
<h3>How to calculate Circumference of a circle</h3>
C = 2πr
where
r = radius
Therefore,
r is the radius of the fairy wheel
r = 20 ft
C = 2 × 3.14 × 20
C = 40 × 3.14
C = 125.6 ft
This shows that the car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet

Answer:
17 m² or 17 square meters
Step-by-step explanation:
A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?
Area of a trapezoid =1/2(b1 + b2)h
Where
b1 = First base length = 5m
b2 = Second base length = 3.5 m
Height = 4m
= 1/2(5m + 3.5m) × 4m
= 1/2(8.5m) × 4m
= 1/2 × 8.5m × 4m
= 17 m²
Therefore, the area of the trapezoid is 17 m² or 17 square meters
