Step-by-step explanation:
Step 1: Set up the formula for the surface area of a regular pyramid.
SA =
where :
- SA equals the total surface area of the pyramid,
- p equals the perimeter of the base,
- h equals the slant height of the pyramid
- B equals the area of the base.
Step 2: Plug the perimeter of the base into the formula
you can calculate the perimeter by multiplying the length of one edge by the number of edges.
Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)
Step 4: find the area of the base (depend on the shape of the base)
Hope it will find you well.
Answer: 68%
Reasoning: To find the experimental probability, we divide the number of students that scored an 80 or higher by the total number of students, so 17/25
17/25 = 0.68 x 100 = 68%
The slope is 30... each week he gains 30 dollars
