A² + B² = C²
So 10² + 10² is 200
The square root of 200 is about 14.14
10² + 10² ≈ 14.14²
Hope that helps :)
The total number of student can be solve by dividing the
partial student by its percentage of the overall student. Since there are 180
students in the band and it represnts 9% of the total students of the scool. So
the number of studetns are 180/0.09 = 2000 students
Answer:
We see two intersecting lines.
It means there is one solution, it is the intersection point.
Solution is (3, 4)
It was easy to find the solution as both lines and their intersection is visible on the graph.
With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.
If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.
With same slopes and different y-intercepts there is no solution.
With same slopes and y-intercepts there is infinitely many solutions.
The % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.
<h3><u>Percentages</u></h3>
Given that last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639, to determine the % decrease in the number of scheduled passenger flights from February of 1999 to last February, the following calculation must be made:
- 709639 = 100
- 617624 = X
- 617624 x 100 / 709639 = X
- 61762400 / 709639 = X
- 87.03 = X
- 100 - 87.03 = X
- 12.97 = X
Therefore, the % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.
