Cost = 15x + 2000
Earning = 35x
At break even, cost = earning
35x = 15x + 2000
20x = 2000
x = 100
100 rides are needed to break even.
If a parallelogram has an area of 7 square units, and the height corresponding to a base is
units, then the base is 28 units.
As per the question statement, a parallelogram has an area of 7 square units, and the height corresponding to a base is
units.
We are required to find out the base of the parallelogram.
To solve this question, we need to know the formula to calculate the area of a parallelogram, which goes as
Area of Parallelogram = (Base * Height)
Putting our data obtain from the question statement, in the above-mentioned formula, we can calculate the value of the base of our concerned parallelogram, i.e.,

Therefore, base of our concerned parallelogram is 28 units.
- Parallelogram: In Euclidean geometry, a parallelogram is a four-sided, plane, closed figure (Quadrilateral) with two pairs of parallel, opposite sides.

A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
80
The absolute value of 78 is < the absolute value of -222
