Answer:
Step-by-step explanation:
You need to use the following formula for calculate the Surface area of a Right triangular prism:
Where "p" is the perimeter of the base, "h" is the height of the prism and "B" is the area of the base.
You can identify that the height is:
The area of a triangle can be found with this formula:
Where "b" is the height of the triangle and "H" is its height.
Knowing this formula, you can find the area of the base of the prism. This is:
Since the perimeter of a figure is the sum of the lenghts of its sides, "p" is:
Therefore, substituting values into the formula, you get:

Step-by-step explanation:
He should choose Alfredo because he shot the highest percentage of 75% or 15 of 20 shots that he made. Whereas Tony only made 14 out of 20 which is 65% and Martin only made 60% or 13 out of 20, so as a coach you want to choose your best shooter.
Answer:
(-2, -9)
explanation:
original coordinates of B: (7, 9)
use the formula: (x, y) ---> (x, -y)
- if reflects over x-axis new coordinates: (7, -9)
If horizontally shifted there will be change in x axis,
- new coordinates (7-9,-9) → (-2, -9)
