because obviously the pyramid has a square base and triangles around it, which rules out c, and if you try and fold them together in your head
For the first flower she has a choice of 15. For the second 14 (15 minus the one that was already used). For the third 13, and so on.
Each of the first 15 can be match with any of the second 14. Any of the first pairs can be matched with ant of the third 13 and so on.
This gives us
Number of Selections = Choices for Flower 1 x Choices for Flower 2 x Choices for Flower 3 x Choices for Flower 4 x Choices for Flower 5

Answer:
9.54 feet
Step-by-step explanation:
Using Pythagoras rule :
Length of ramp = 10 feets = hypotenus
Hypotenus² = opposite² - adjacent²
d² = 10² - 3²
d² = 100 - 9
d² = 91
d = √91
d = 9.5393920
d = 9.54 feets
